Current JavaEE deployment requires the deployer to provision the various dependent services of an application in that container. To support PaaS deployment scenarios, GlassFish is working to provide a simplified application provisioning and deployment interface to users, with the runtime handling the discovery of service dependencies, provisioning services, and associating service references with these services. Some of the metrics (such as CPU, memory, and response times) can be used to monitor system health. These metrics can then be used to determine if the cluster of virtual machines hosting the JavaEE container needs to be dynamically expanded or shrunk to accommodate fluctuations in demand.

This session details how JavaEE containers such as GlassFish can provide such service orchestration and elasticity capabilities. This session will take an existing JavaEE 6 application and walk through the complete life cycle of taking this application from desktop to a PaaS environment. The session will explain the development, testing, and debugging of such an application in the PaaS envinronment.

Furthermore, JavaEE 7 continues the ease of development push that characterized prior releases by bringing further simplification to enterprise development. It also adds new, important APIs such as the REST client API in JAX-RS 2.0 and the long awaited Concurrency Utilities for JavaEE API. Expression Language 3.0 and Java Message Service 2.0 will under go extreme makeover to align with the improvements in the Java language. There are plenty of improvements to several other components. Newer web standards like HTML 5 and Web Sockets will be embraced to build modern web applications.

This talk will provide a complete introduction to the JavaEE 7 platform, including different components, and provide a roadmap.

This session aims to cover some scalability and load distribution considerations we followed while developing application which had to scale to a million users.

It will cover the following considerations:

1. Restful Architecture: Heart of horizontal scalability and distributed application.
2. Stateless UI: No need to do extra configuration if you do follow simple guideline
3. MySQL master/slave replication: Use it to maximum
4. Separate read and write layer: Divide and Rule.
5. Distribution of load: In horizontal scaling how you can distribute load across your nodes/server. This applies specifically to daemon processes running in background to perform some CPU intensive processes (like data mining) or some low priority non-real time processes (like sending some (non-critical) notifications to users) or batch processing.
6. DB sharing: Idea is to divide data physically so that each cluster should have its own users data

The talk will discuss learning from a system GSLab built using java/j2ee technologies. This particular product required to have support of 1 million user and processing packets coming from each user after every two hour to show it on users dashboard.

We will also go through the workload distribution technique we have used which is required for batch processing of data using Quartz library.

In the session I plan to talk about following points:
1. What makes it hard to test and write Multithreaded code.
2. Improving design and structure of Multithreaded code to enhance the testability.
3. Writing Effective Unit tests for concurrent programs.
4. Demo – build a small example application using concurrency and putting test safety net around it.
5. Share some interesting situations faced while developing a Multi-core application and remedies applied.

A relatively new entrant to this space is Gradle. Built using Groovy it offers an extremely flexible means of describing builds with only as much text as is absolutely necessary thanks to it’s powerful plugin infrastructure and sensible conventions borrowed from existing tools.

This session will introduce the audience to Gradle, the various DSLs used to describe builds as well as the plugin infrastructure that allows for extending Gradle’s capabilities.

Speaker:

A software consultant with over 8 years of experience in a wide range of technologies, I,ve spent the last couple of years at ThoughtWorks, brainstorming solutions for anything from microsites for text-messaging apps and specialized product tracking services to arguing over enterprise-wide deployments of integrated virtualization and source control systems. And that’s when I wasn’t busy building eCommerce apps! Now, I work at Vayana Services, building B2B integration services connecting enterprises and banks. As a self confessed Java evangelist, I have always tried to keep myself updated about technologies and new developments at the edges of this space.

This case study shall focus on the following points:

1. Why choose Solr as your search engine : What lured us to go for Solr
2. Solr offers various configurations and components to build a Google style Suggestions engine – Elicit pros and limiting factors of these components and highlight when to use which component.
3. Fuzzy Searching with Solr – I want to search ‘Karan’ but I type ‘Naran’ yet Solr finds it. – Analyse what fuzzy searching can do for you and to what extent should you stretch your engine’s fuzzy search quotient.
4. Discuss Solr scaling topology – Point out what factors should you consider while scaling Solr
5. Unit testing Solr code

The presentation would walk through the Akka features for building a web scale system. We would look at a real world case study in which Inphina developed a web scale framework using Akka which is capable of processing 150 million streaming messages a day. We would discuss the architecture and key design decisions.

Takeaways would include an understanding of Akka, its features which would help in developing a scalable system, potential architecture and pitfalls to be cautious about.
