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.

Real-world Integration case studies and patterns part 1

Building 3rd party integrations require deep understanding of the business problems. You would not want to reinvent the wheel to solve common issues. In this talk we will explore different case studies with patterns which helps solves real world issues. We will start with exploring SOA patterns like Service host, Active service, Transactional service, Workflodize, Edge component. After that we will look at patterns related to performance, scalability and availability like Decoupled invocation, parallel pipelines, Gridable service, Service instance, Virtual Endpoint, and Service watchdog.
Lastly we will dive into security and manageability patterns like Secured message, Secured Infrastructure, Service firewall, Identify provider, and Service Monitor. Message exchange patterns include Request/Reply, Request/Reaction, Inversion of Communications and Saga. In Service consumer pattern we will explore Reservation, Composite front end and client/Server/Service. In Service integration patterns we will explore Service bus, Orchestration, Aggregated reporting. Lastly we will examine Service anti-patterns like Knot, Nanoservice, Transactional integration.

Cloud Architectural design patterns blueprints

In this talk, we will explore different cloud computing architecture design patterns blueprints and how you can take advantage of them. We will study cloud patterns for Private and Hybrid cloud deployments, Cloud Services, Common cloud management platforms, Security, Cloud governance, resiliency, Performance, and consumability.

Enterprise Security, Privacy and Data compliance

Data integrity, security, recovery, privacy and regulatory compliance are essential attributes for enterprise implementation. Enterprise customers ask for transparency in how the vendors will provide security programs. Many questions need to be asked for any cloud implementation to policy makers, architects, coders, and testers.
In this presentation, we will explore data security and storage, privacy, and data compliance issues. We will explore the security management in the cloud. The presentation is useful for anyone starting from Executives to developers who are going to implement the Enterprise Applications in both private and public cloud.

15 Best Practices for designing Enterprise RESTful APIs in cloud

API Gateway is a way to connect real-world 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

Introduction to Apache Cassandra
