Cloud continues to grow in importance in even the most conservative companies’ IT strategies. Because of this, even experienced software architects must confront a new world in which many of our normal architectural assumptions no longer hold. Before we create architectures that leverage cloud infrastructure, we need to rebuild our mental model of infrastructure around the appropriate concepts and principles. The purpose of this session is to do just that.

In this session we’ll:

• tour the current cloud infrastructure landscape
• explore the key business and technology motivators for adopting cloud
• explore the unique aspects of cloud infrastructure that violate our traditional assumptions
• examine the risks associated with adopting cloud infrastructure
• navigate some of the key tradeoffs involved with cloud architecture choices
• overlay traditional architecture patterns and examine their suitability to cloud
• define a cloud native architecture that is optimized to exploit the uniqueness of the cloud environment

The learner should leave this session prepared for deeper dives into cloud native architecture patterns and migration strategies.

NOTE: We'll cover roughly 50% of the material in Part 1.

NOTE: We'll cover roughly 50% of the material in Part 1. If you come to only Part 2, we'll be starting in the middle.

Now that we’ve been equipped with an understanding of how software architectures can exploit the unique aspects of cloud infrastructure environments, it’s time to construct a pattern catalog that can guide our decision making as we journey from concepts and principles to concrete implementations. The software industry has long been motivated by the promise of a “component marketplace” from which we can draw commodity components which can be composed via standardized mechanisms to create powerful systems. These systems are often compared to the myriad of possible creations that can be produced using Lego pieces. The power in the Lego “architecture” is found in the amazing diversity of individual pieces that are composed via a universal system of compatibility. Cloud native architectures approximate the same power via Lego-like patterns.

In this two-part series, we’ll divide the cloud native patterns into two categories:

1. Bricks - how we design cloud native services
2. Mortar - how we compose cloud native systems

In part one we’ll study “Brick Patterns” from the following categories:

• Externalized Configuration
• Externalized State
• Externalized Channels
• Runtime Reconfiguration
• Continuous Delivery via Multi-Version Concurrent Execution
• Brick Telemetry

The learner should leave this session prepared to design and implement cloud native “bricks” that can be composed via any “master builder” of cloud native solutions.

• Contract Management
• Integration Telemetry

The learner should leave this session prepared to compose cloud native solutions from any available collection of cloud native “bricks.”

If you’ve been following along, you’ve realized by now that cloud native architectures are fundamentally different than most traditional architectures. Most of the cloud native architectures that we can see in the wild have been built by relatively young companies that began from a zero-legacy state. Architects in more mature organizations are faced with the daunting challenge of building modern systems that exploit the unique characteristics of cloud infrastructure while simultaneously attempting to migrate legacy systems into those same environments, all the while “keeping the lights on.”

Much of the last two years of my career have been spent helping Fortune 500 companies devise cloud native migration strategies, and I’ve built a increasingly large catalog of patterns that have proven useful across multiple systems and industry verticals. In this session we’ll dive into those patterns and more, including:

• the utility of cloud native maturity models
• the cloud continuum: cloud ready, cloud friendly, cloud resilient, cloud native
• the app continuum: evolving toward distributed systems
• criteria for selecting applications to migrate
• the occasionally palatable perils of “lift and shift”
• applying the Strangler Pattern
• leveraging strategic domain-driven design: bounded contexts, context maps, and anti-corruption layers
• insulating from “irreplaceable” legacy systems of record with hexagonal architecture

The learner should leave this session with a tool belt suitable for attacking an upcoming cloud native architecture migration effort.

On the 2017 tour, I introduced the notion of “serverless” and Functions as a Service (FaaS) platforms. We understood the motivation for serverless computing, compared serverless to other cloud-native infrastructure approaches, navigated some architectural tradeoffs, and took a whirlwind tour of the Big 3 FaaS providers.

In this 2018 edition of the talk, we’ll still cover a few of the same themes to bring new folks up to speed, but we’ll also look at what’s changed in this ecosystem over the past year, take a look at new or enhanced features, offerings, runtimes, and programming models, and examine what use cases are becoming popular for serverless computing. We’ll also look at how tradeoffs have evolved, and definitely throw in a few demos.

Java 8 is the most significant change to the language since it's introduction, surpassing changes seen in any of the previous versions. It is not merely syntactical change or addition of a few extra features, it's a paradigm shift. Come to this presentation to learn about the power and capabilities of functional programming using Java 8 and how to benefit from those when building Java applications.

Lambda Expressions
A Look under the hood
Stream
Functional Programming Principles Applied
Function Pipeline
Lazy Evaluations
Parallel Streams

Functional programming promotes immutability and using higher-order functions. Functional code is in general easier test, but lambdas and lazy evaluations pose some challenges from the tools point of view. That's where JUnit 5 comes in.

Learn the challenges to testing functional style code and how JUnit 5 addresses those.

Turning a stream into a parallel stream is extremely easy, but is that the prudent thing to do? While flipping that switch is almost effortless there are some significant ramifications. In this presentation we will learn the power of parallel streams but also why, when, and where it makes sense to use parallel streams. Through a series of example we will learn about cases where it makes sense and some there it does not.

Streams
Parallel Streams
Controlling Threads
Deciding Threads
Performance Implications
Recommendations on prudent use

If Java 8 was all about how we code, Java 9 is all about how we will build. Modularization will have the biggest impact of any change that happened in Java since its inception. In this presentation we will learn about the need for modularization, how it impacts development, the rules to follow when creating modules, and the effect it has on legacy code.

We will explore creating module, using modules, readability, exports, automatic modules, and unnamed modules.

JShell, introduced in Java 9, is a great experimentation tool, useful for micro-prototyping, and trying out code snippets. In this presentation we will learn the benefits of the tool, when to use it, and how to put that to real good use during development.

In this example driven presentation we will look at writing snippets, creating functions, defining and redefining variable and methods, creating classes, and configuring the tool to meet your desired level of feedback.

In this session we will take a look at building applications with Angular. We will build a very simple application from the ground up, and attempt to understand the approach of Angular, as well as understand some of the terminology that Angular introduces.

This session will focus on the Angular 10

TypeScript, Components, Annotations/Directives, Observables, Reactive Stores, Model-Driven forms … Oh my! Angular, much like AngularJs (1.x.x), despite being a powerful platform for building rich client side applications, comes laden with both new terminology, and a “newer” approach to writing client side code.

In this session, as we build a simple application, we will attempt to tease apart these concepts, slowly building our understanding towards how these pieces come together, and how we can leverage them to build rich client side application.

Details

• Quick overview of what Angular has to offer, how it is different from Angular 1.x
• A glance at the project we are going to build, and all the important files that angular-cli generates
• Create our first component
• Proceed with creating a component hierarchy to display all hard coded data

Along the way we will see how to use the Angular style guide to follow conventions adopted by the Angular community at large, and some ways to use the angular-cli tool.

Details

• Using in-build pipes in Angular
• Create our own pipe
• Create the necessary infrastructure to allow for HTTP Calls to the backend
• Load all the containers using Ajax
• Introduces routing, and update the homepage to navigate to these routes

Along the way we will see how to use the Angular style guide to follow conventions adopted by the Angular community at large, and some ways to use the angular-cli tool

In this session we will get acquainted with Docker. We will discuss what docker is, how to install it, and how to start using Docker. We will also explore some of the benefits of containerizing your applications.

Containers are taking over the world. Containers provide a means to have hermatic builds of your software, allowing for truly immutable testing, and delivery of your software. Docker is one of many containerization technologies, and in this session we will take a brief look at Docker and what it has to offer.

In this session we will dive deeper into Dockerfiles. We will explore the DSL that Dockerfiles provide to allow for the automation of image creation.

Dockerfiles provide a means to automate the creation of images, and consequently the containers within which our applications run. The Dockerfile, though minimal, provides us with everything we need to package our software, and enable it to run. In this session we will dive deep into the Docker DSL, and explore the many commands that it provides, and along the way explore some differences between similar commands, and some gotchas.

Kafka has captured mindshare in the data records streaming market, and in this presentation, we knock on its door and see what lies behind. What is the draw? What makes it an attractive addition? How does it compare to Message Queues and other message streaming services?

We will do a thorough introduction into what is Kafka. We will also discuss Consumers, Producers, Streams. Integration with ZooKeeper, and discuss the performance aspect of using Kafka.

Java 8 is pretty great, but mix in JavaSlang (now called Vavr) and get ready for some functional programming excitement.

JavaSlang is a project that decorates Java with immutable data structures, better Optionals, tuples, and more. Now with JavaSlang (Vavr) we can really bring in some more power to functional programming and Java. We will even discuss some new concepts like for comprehensions, Try, and Either!

Reactive is a the latest buzzword to consume our industry. This presentation distills and defines reactive systems, describe the difference between reactive architecture vs. reactive programming, describe common patterns, and demos the popular reactive JVM technologies like RXJava, and Akka.

Introduction to reactive gets in deep on a discussion of patterns: Source, Sink, Back Pressure, Reactive Pull/Push including a Light introduction to actors using Akka, ReactiveX using RXJava and Reactive Streams in RXJava and Akka. We also will showcase the differences between ReactiveX and Akka.

Starting with JDK 5, we have had Futures, and they mostly went ignored. Now with concurrency and reactive technology in demand, it is essential that we understand what futures are, and how to handle them and make use of their power in asynchronous systems.

This presentation is a basic ground up introduction to Futures. We start with Futures and how they came packaged with JDK 5. We take a look at Executors, how to create a thread pool, which pool you should choose. How to model Futures in the JDK and show the difference for awaiting the answer and taking on the answer asynchronously. We also take a look at what a Promise is and when to use one. We then invest time taking a look at Guava's callback solution. Then we finally look at the handling of futures in both Scala and Clojure.

ReactiveX is a set of Reactive Extensions developed by Netflix, and is developed for various programming languages, like Java, Scala, and Clojure. ReactiveX overhauls the observable design pattern to achieve reactive goals. This presentation will solely focus on the Java version of ReactiveX, RXJava.

RXJava is combining the Observer Pattern with Functional Programming to compose complex asynchronous reactive systems. This presentation will also give an overview on RXJava concepts like Source, Sink, BackPressure and Reactive Pull and Push.

On the NFJS tour, there are questions that seem to come up again and again. One common example is “How do we determine which new tools and technologies we should focus our energy on learning?” another is “How do we stop management from forcing us to cut corners on every release so we can create better and more maintainable code?” which, after awhile becomes “How can we best convince management we need to rewrite the business application?”

There is a single metaanswer to all these questions and many others.

It begins with the understanding that what we as engineers value, and what the business values are often very different (even if the ultimate goals are the same) By being able to understand these different perspectives it's possible to begin to frame our arguments around the needs and the wants of the business. This alone will make any engineer significantly more effective.

This session picks up from where “Stop writing code and start solving problems” stops discussing what is value, how do we align the values of the business with the needs and values of the engineer.

It happens to us all; there are simply days where it seems impossible to get anything done. This session focuses on techniques and tips to get into the zone, stay in the zone and to protect your productivity, even in disruptive environments.

Rather than focusing on any one productivity methodology (e.g. GTD) This talk analyzes the internal and external factors that affect our productivity and offers broader strategies to get back on track.

Continuous delivery is not a pipe-dream technology, reserved only for the “cool kids” at hip tech startups. Although it's not easy, many concepts are within reach of most teams. That being said, it require more than simple technology changes. Attend this session to learn the fundamental concepts of CD, how to build your CD pipeline with Gradle and Jenkins, and recommendations on tools and best practices.

No prior knowledge is assumed and this talk will start from first principles.

Part one begins with a detailed overview of what CD is (and isn't) and how to build a business case for CD. Making both the technical case and business case for CD is vital as it's necessary to get the entire organization on board with the changes required.

Part two is a deeper dive into building a continuous delivery pipeline with Gradle and Jenkins (although the broader concepts can be applied to the tooling of your choice) You'll see how easily Gradle integrates with Java and how to leverage configuration management and gradle plugins to build all of your quality gates.

A Technology Radar is a tool that forces you to organize and think about near term future technology decisions, both for you and your company. This talk discusses using the radar for personal breadth development, architectural guidance, and governance.

ThoughtWorks Technical Advisory Board creates a “technology radar” twice a year, a working document that helps the company make decisions about interesting technologies and where we spend our time. ThoughtWorks then started conducting radar-building exercises for our clients, which provides a great medium for technologists company-wide to express their opinions about the technologies they use every day. For companies, creating a radar helps you document your technology decisions in a standard format, evaluate technology decisions in an actionable way, and create cross-silo discussions about suitable technology choices. This session describes the radar visualization and how to conduct a radar building session for yourself. After a brief introduction, the bulk of the workshop consists of attendees building a radar for the group, following the same procedure you'll use when you do this exercise at your company. At the end, we'll have created a unique Radar for this event and practiced doing it for yourself.

By the end of this conference you will have learned many new tools and technologies. The easy part is done, now for the hard part: getting the rest of the teamand managementon board with the new ideas. Easier said than done.

Whether you want to effect culture change in your organization, lead the transition toward a new technology, or are simply asking for better tools; you must first understand that having a “good idea” is just the beginning. How can you dramatically increase your odds of success?

You will learn 12 concrete strategies to build consensus within your team as well as 6 technique to dramatically increase the odds that the other person will say “Yes” to your requests.

As a professional mentalist, Michael has been a student of psychology, human behavior and the principles of influence for nearly two decades. There are universal principles of influence that neccessary to both understand and leverage if you want to be more effective leader of change in your organization.

In this session we discuss strategies for getting your team on board as well as when/how to approach management within the department and also higherup in the organization.

In Part 1, you learned the core principles of influence and persuasion. How to we take this back to the office and apply what we've learned?

We dive deep in to specific strategies to get both the team and the business on board with your ideas and solutions. We cover several realworld patterns you can follow to be more effective and more persuasive. Part 1 was conceptual, part 2 is practical.

This is a revised and updated version of the previous talk, with current thinking from practice and the literature. The talk presents why conflicts with your manager are inevitable based on differences in priorities and perspectives, and how to plan for them. The goal is to show you how to build the loyalty relationship that allows you to get what you need when you need it.

Topics covered will include diagnosing communication styles, lessons from game theory, working within the organizational hierarchy, and lessons on how to build a relationship with your manager that still allows you the freedom to express yourself and what you really want.

Distributed and parallel computing have been around for a while. The problem is not new, but solutions have generally been complex. Over the years several solutions have come along to ease the pain. Spark is a wonderful programming API and a tool that can ease the pain of creating distributed, high concurrent, performing code.

In this presentation we will take an example oriented approach to creating applications that make use of Spark. We will learn how to create the code to use Spark, how to configure and manage the number of threads, and how to distribute the computations.

We all have seen our share of bad code and some really good code as well. What are some of the common anti patterns that seem to be recurring over and over in code that sucks? By learning about these code smells and avoiding them, we can greatly help make our code better.

Come to this talk to learn about some common code smell and to share your experiences as well.

Back in the day, web developers had to rely on their wits and a plethora of alert statements - to say our toolkit was spartan would be an understatement. But with the increased importance of web front ends and the rise of JavaScript MVC frameworks, a modern web developer toolkit is finally emerging.

We've evolved from text editors to full fledged IDE's with code completion and refactoring tools but our toolchain doesn't end there. With multiple testing libraries, mocking frameworks, test drivers and even code coverage tools, today's web developer gets to walk downhill on a sunny day.

Take a look at your codebase. Go ahead, this abstract will wait. Notice anything? Perhaps a few more lines of JavaScript than years past? JavaScript is no longer an outlier, a language for the interns, something we can just mash together. Today, JavaScript is a first class citizen. As such, we need to treat it will all the care and feeding we extend our server side languages. This talk will introduce you to a set of tools that will help you write bulletproof JavaScript.

Step one, make sure we aren't making any basic mistakes like using == when we really mean ===. To remedy these types of bugs, we'll leverage JSHint to statically analyze our code. In addition to walking through the setup, we'll discuss how to ratchet up the rules as you improve your codebase. Just like Java or C#, we also need to test our JavaScript code. We'll introduce Jasmine, a BDD style testing tool as well as other tools that make help in the testing process. Last but not least, we'll take a tour of Plato, a JavaScript source code visualizer. Taken together, these tools can go a long way to improve your JavaScript code.

In this example-driven presentation, you'll learn how to leverage Spring Boot to accelerate application development, enabling you to focus coding on logic that drives application requirements with little concern for code that satisfies Spring's needs.

For over a decade, Spring has sought to make enterprise Java development easier. It began by offering a lighter alternative to EJBs, but continued to to address things such as security, working with various sorts of databases, cloud-native applications, and reactive programming. And, along the way, Spring even took steps to make itself easier to use, offering Java-based and automatic component configuration. Even so, there's still a lot of near-boilerplate code required to develop Spring applications.

Enter Spring Boot. Spring Boot's primary purpose is to make Spring easier to work with. It achieves this in three ways:

• Automatic configuration : Considering what's on the runtime classpath as well as other factors, Spring Boot can automatically configure components in a Spring application context.
• Simplified dependency management : Taking advantage of transitive dependency resolution at build-time, Spring Boot offers several “starter” dependencies, focused on specific characteristics of an application, that transitively bring in libraries to enable development of those characteristics.
• Runtime insight : Spring Boot offers insight into the inner workings of a running application via REST endpoints and/or JMX MBeans to better understand what makes a running application tick.

All together, Spring Boot lets you focus on fulfilling your application's requirements without worrying about writing code that satisfies the needs of a framework.

In this session, you'll learn how to take your Spring Boot skills to the next level, applying the latest features of Spring Boot. Topics may include Spring Boot DevTools, configuration properties and profiles, customizing the Actuator, and crafting your own starters and auto-configuration.

TBD

In this session, you'll learn how to use Spring Data to rapidly develop repositories for a variety of database types, including relational (JPA and JDBC), document (Mongo), graph (Neo4j), and others (Redis, Cassandra, CouchBase, etc).

For decades, relational databases and SQL have enjoyed their position as the leading choice for data persistence. Even though many alternative database types have emerged in recent years, the relational database is still a top choice for a general purposes data store and will not likely be usurped from its position any time soon. When it comes to working with relational data, Java developers have several options.

But relational databases are not a one-size-fits-all solution. Thankfully, there are many options for data persistence, including relational, document, graph, key-value, and column-store databases, each presenting their unique way of handling data suitable for different problems.

Spring Data makes it easy to work with various databases by offering a programming model that is consistent, regardless of which type of database you're working with. And regardless of the database you're dealing with, you will find that Spring Data eliminates a lot of boilerplate code.

In this session, you'll see how to take Spring Data's automatic repository generation to a whole new level. We'll look at ways to model data and manipulate Spring Data to produce repositories and APIs that are more than just CRUD layers on top of a database.

TBD

In this session, we'll explore the new reactive features in Spring 5 to build reactive, non-blocking applications using Spring's familiar programming model.

Traditionally, applications have been built using a blocking, synchronous model. Although comfortable and intuitive for most programmers, this model doesn't scale well. And although there are several new approaches to reactive programming, they don't necessarily fit into the familiar programming model that Spring developers are accustomed to working with.

Spring 5 has introduced a set of new reactive features, enabling non-blocking, asynchronous code that scales well using minimal threads. Moreover, it builds on the same concepts and programming models that Spring developers have used for years.

Gradle is the build tool of choice in the open source world, and rapidly becoming the standard in industry as well. Anyone who works with Gradle on a Java project knows the basics of the Java plugin and how to write simple tasks in Groovy. Gradle can do much more, however. This talk will demonstrate how to write your own custom task classes and how to create Gradle plugins from them. Other Gradle features will be demonstrated as well, including file manipulation, incremental builds, generating the Grade wrapper, and resolving conflicts in dependencies.

Gradle Inc also provides a free build scan capability to analyze build files. This too will be demonstrated, as well as profiling your build, determining dependencies, and more.

For the last several years, the JavaScript world has been awash in various Model-View-Whatever frameworks and libraries with new implementations popping up like bunnies. With the popular React library, Facebook took a different approach to developing JavaScript user interfaces by focusing on the View in MV*. This talk will get you up and running on React, a library that gives us a declarative approach to designing highly performant interactive user interfaces. We'll dive into the basics of components, JSX, the virtual DOM and more. By the end of this session you'll have a solid foundation in what React brings to the table and how it might help you on your next project.

JavaScript UI frameworks continue to evolve but centers of gravity have clearly formed around Angular and React. With both libraries boasting of big company backing and passionate communities, which one is right for your next project? While we cannot crown the one true framework, we will dive into the differences and the similarities with an aim to help you make an informed decision on your next web project.

Picking a framework is often fraught with clashing opinions, in this talk I'll try to help you make a good choice for your team.

The technology space is a lot like the ocean - miss one wave and another will come along shortly; most shiny new things begin with a sizable amount of hype as everyone rushes to play with the new toy. This cycle is often met with a level of disappointment as we quickly discover our new bauble isn't all that and a bag of chips so we rush off to the next best thing ever.

A few short years ago, HTML5 was the new hotness but at the time browser support was spotty at best. Despite the spotlight moving on to something else, browser support has improved markedly and we even have new toys to play with! In this talk, I will walk you through what is possible in today's browser as well as what other new features you might not be aware of. HTML5 may no longer qualify as bleeding edge, but it is still deserving of our attention.

An evolutionary architecture supports incremental, guided change along multiple dimensions.

For many years, software architecture was described as the “parts that are hard to change later”. But then microservices showed that if architects build evolvability into the architecture, change becomes easier. This talk, based on my upcoming book, investigates the family of software architectures that support evolutionary change, along with how to build evolvable systems. Understanding how to evolve architecture requires understanding how architectural dimensions interact; I describe how to achieve appropriate coupling between components and services. Incremental change is critical for the mechanics of evolution; I cover how to build engineering and DevOps practices to support continuous change. Uncontrolled evolution leads to undesirable side effects; I cover how fitness functions build protective, testable scaffolding around critical parts to guide the architecture as it evolves.

The software development ecosystem exists in a state of dynamic equilibrium, where any new tool, framework, or technique leads to disruption and the establishment of a new equilibrium. Predictability is impossible when the foundation architects plan against changes constantly in unexpected ways. Instead, prefer evolvability over predictability. This keynote illustrates how to achieve evolutionary architectures and how to retrofit existing systems to support better evolution.

This session covers two critical soft skills for architects:

• creating clear, concise documentation of software architecture, both structure and decisions
• presenting architectural ideas as clearly as possible

New architects find soft skills like creating lucid documentation and building compelling presentations challenging. This presentation covers a variety of ways to document ideas in software architecture, ranging from diagramming techniques (that aren't UML) to Architecture Decisions Records and ultimately to presentations. The second part of the talk leverages patterns and anti-patterns from the Presentation Patterns book to help architects build clear and concise representations of their ideas.

This session compares Service-oriented, Service-based, and Micro-service architectures, describing the problem each is designed to solve, differences and similarities, variants and hybrids, and engineering practices.

Microservice architectures are quite popular, described as “SOA done correctly”. But what are the real differences between SOA, Microservice, and service-based architectures? What about middle ground between the shared everything of SOA versus shared nothing of microservices? This talk explores the similarities and differences between various service-oriented architectural styles. I describe the characteristics of SOA, microservices, and hybrid service-based architectures, along with the considerations and constraints for each. I also discuss specific engineering practices, orchestration styles, reuse strategies, and migrating from monolithic applications to service-based or microservice architectures. No one architecture can solve every problem, and many projects take on more complexity than necessary by choosing the wrong paradigm.

The Gradle build tool is one of the most successful projects in the Groovy ecosystem because it addresses a difficult problem – every major build is a custom build. Gradle builds are written in Groovy, so the full power of the language is available if you need it. Gradle supports Maven project structure and repositories and uses Ivy dependency management without being bound by their normal constraints. With major systems like Grails, Hibernate, and the Spring Framework moving to Gradle, this is a technology worth taking the time to understand.

This talk will cover the basics of Gradle both through simple examples and by examining the build files for major open source projects.

Traditional approaches to software architecture do not address the core tenet of all agile practices - feedback! We make many of the most important architectural decisions early in the development lifecycle and fail to get accurate feedback on those decisions throughout implementation. Compounding the problem? Agile methods offer no architectural advice. This session explores several architectural practices that help increase architectural agility.

What’s the goal of architecture? To serve as a blueprint of the system that everyone understands? Possess the flexibility to evolve as new requirements emerge? To satisfy the architectural qualities, including performance, security, availability, reliability, and scalability? Yes. Yes. Yes. At the heart of these three questions are the three pillars of architecture - social, process, and structure. But how do we create software architectures that achieves all of these goals? And how do we ensure no disconnect occurs between developers responsible for implementation and architects responsible for the vision? In this session, we’ll explore several principles to increase architectural agility and provide some actionable advice that will help you get started immediately.

Recently, microservices have take the development community by storm. Though a modern architectural paradigm, the underlying principles of microservices are embedded across many proven traditional architectural approaches, especially modularity. At the end of the day, microservices are just one way to the increase modularity of our software system. But there are others.

In this session we will examine several different ways to modularize large software systems. We'll start with the “modular monolith” and demonstrate how this modular monolith gives us a significant degree of architectural agility to evolve the architecture to microservices by incrementally breaking pieces of the application off and deploying them as microservices.

Microservice architecture is a modern architectural approach that focuses on breaking apart the monolith and building modular services. But the framework we use has a tremendous impact on how we build and deploy services. A new type of framework has emerged that provides a lightweight stack for building microservices.

In this session, we will explore some modern Java micro frameworks for building microservices. Example frameworks you may see include Dropwizard, Spark, Ninja, RestExpress, Play, Restlet, and RestX.

The way we build and deliver software is changing. We must deliver software more quickly than ever before and traditional approaches to software architecture, infrastructure and methodology do not allow us to meet demand. We’ve reached the limits of agility through process improvement alone, and further increases demand we focus on improving architecture, infrastructure, and methodology simultaneously. 12 Factor is an app development methodology for building modern apps in the modern era.
