Apache Cassandra, Spark and Spark Streaming for Real Time Big Data Analytics

Apache Cassandra is one of the best solutions for storing and
retrieving data. We will explore data analytics cluster computing
framework with real-world examples. It is 100x faster than Hadoop!
We will start with an introduction to Apache Cassandra. We will explore challenges encountered when attempting to scale
with relational databases, and how NoSQL databases like Cassandra address those problems. It reviews the Cassandra architecture, benefits, and how to use the Cassandra read and write paths.

Later, you will learn how to effectively and efficiently solve analytical problems using Apache Spark, Apache Cassandra, and DataStax. You will learn about Spark API, Spark-Cassandra Connector, Spark SQL, Spark Streaming, and fundamental performance optimization techniques.
Big Data applications nowadays require a faster speed of data
processing and analysis.

Next, Cloud security is a must to be incorporated throughout application development. We will explore Threat Modeling, SOC2 compliance, disaster recovery, and different ways to identify and fix vulnerabilities. Next, we will explore design principles to build support for availability, failover strategies, and downtimes. We will explore ways to design applications, which support <500 ms response time. Next, we will discover how modern cloud enabled applications need to be built using 12 factor application model. Lastly, we will look at how Dockers, Kubernetes, and Mesos DC/OS are helping build scalable Cloud applications.
You can now directly apply your knowledge of architecture principles through this workshop. This will be helpful in enhancing your architect skills with constructive feedback from attendees. You can also come with your organization’s architectural challenges.

Best Practices for designing Enterprise RESTful APIs in cloud workshop

API Gateway is a way to connect Enterprise application in cloud-ready applications. New applications need to design the data model and create public APIs to be consumed by mobile apps, third party apps, and different devices. We will explore best practices, which you must adopt to be cloud ready. Firstly, we will examine how contract first API development is helping enable more extensible and reliable APIs. Next, we will look at
We will ask tough questions during this design session. How to provide security? What are best practices to authenticate? When should we version APIs? Should we use HATEOS for developing APIs? How to support internationalization? How to publish and maintain APIs?

Enterprise Ethical Hacking Cloud Applications

Securing of the web application is an enormous task. In this talk, we will explore how to protect enterprise applications. We will explore different kinds of vulnerabilities and hot to secure your applications properly. Security patterns need to be understood by first wearing the hat of a hacker and then putting the hat as a defender. In this workshop, we will explore different security patterns and determine how to prevent attacks.

We will be using Kali Linux to understand Ethical hacking techniques using Metasploitable applications. In the end, we will see how OpenVas can help in scanning the vulnerabilities in the application.

Containers 101 using Dockers and Kubernetes Workshop

Kubernetes and Docker Swarm are universally used tools to deploy containers inside a cluster. Both are created as helper tools that can be used to manage a cluster of containers and treat all servers as a single unit.

Docker is an open platform for developing, shipping, and running applications. In this talk, we will discover how Docker help separates your applications from your infrastructure and treat your infrastructure like a managed application. Docker helps you ship code faster, test faster, deploy faster and shorten the cycle between writing code and running code. We will explore Docker architecture. We will investigate how you can create your image and compose and deploy in Docker hub so others can start using the same environment. Docker Swarm is native clustering for Docker. It turns a pool of Docker hosts into a single, virtual Docker host. Because Docker Swarm serves the standard Docker API, any tool that already communicates with a Docker daemon can use Swarm to scale to multiple hosts transparently.

Kubernetes is Google’s answer to an open-source system for automating deployment, scaling, and management of containerized applications. In this talk we will discover how to use Kubernetes which is portable: public, private, hybrid, multi-cloud; extensible: modular, pluggable, hookable, composable; self-healing: auto-placement, auto-restart, auto-replication, auto-scaling.
