Webinar: Resistance Is NOT Futile: How to talk Spring and Influence People

News | Pieter Humphrey | July 08, 2013 | ...

Sure the new features coming out in Spring Framework 4.0 are super exciting, but what about those of us that are still explaining dependency injection to our junior developers? And while Spock, Geb, and spring-test-mvc are revolutionizing our ability to test applications, what about the senior developers that are still justifying the value of unit testing to their managers. Strong technical leadership can overcome the organizational inertia that often resists your team's adoption of Spring technologies. Improve your leadership skills by drawing from lessons that were learned during the process of migrating Liberty University's software development department from "cut-and-paste coding" in ColdFusion to enterprise grade application development on the Spring Framework. Learn to plan an effective technology adoption strategy that avoids "new technology overload" and balances the pace of technology improvement with the necessity to continue production. Relationships with managers, junior developers, and production system administrators will all be important. Gain a better xtunderstanding of nontechnical managers and explore strategies for providing the conte they need to make the right decisions. Examine ways to build mentoring plans for your junior developers that include but extend beyond training and certifications from SpringSource University so that you can spend less time teaching and more time coding.

Webinar: Introducing Reactor - A framework for asynchronous applications on the JVM

News | Pieter Humphrey | June 26, 2013 | ...

The sheer volume of non-human-generated data in modern applications can easily overtake a traditional single-threaded, blocking design model. Reactor aims to address this volume, by providing a foundational framework for JVM applications -- applications that need high throughput when performing reasonably small chunks of stateless, asynchronous processing. Join Jon Brisbin as he discusses the motivations behind the project, the design patterns and existing technology that inspired the project, and how it fits in the asynchronous ecosystem today, as a teaser to his upcoming session at SpringOne 2GX 2013.

Webinar Replay: Building REST-ful services with Spring

News | Pieter Humphrey | June 25, 2013 | ...

Today's applications don't exist in isolation. REST applications and web services are a great way to connect applications together. REST is a design principle that imposes no constraints on the client except basic HTTP support, which all platforms provide. Designing REST services, however, is still as much art as it is science, as standards are emerging. Join Spring Developer Advocate Josh Long as he introduces some of the ins-and-outs of REST API design with Spring, building on Spring MVC, Spring HATEOAS and answers some commonly- asked questions like how to secure REST-ful services, and how…

SpringOne 2GX 2012 Replays: Virtualizing and Tuning Large Scale Java Applications, From Spring and Java to Spring and Akka

News | Pieter Humphrey | April 09, 2013 | ...

Virtualizing and Tuning Large Scale Java Applications

This session shares many of the production proven methods of running Java on vSphere. Covering how to size JVMs, and VMs for large scale deployments. The session will have a special section on GC tuning and show how a wide range of JVMs can be tuned using a GC recipe developed over the past 15 years of actual field experience in tuning JVMs.

Three key trends and associated tuning techniques are discussed in this session. The key trends are: Consolidation, Elasticity and Flexibility, and Performance

Consolidation Many of our customers find that their middleware deployments have proliferated and are becoming an administrative challenge associated with higher costs. We see a trend across customers who look to virtualization as a way of reducing the number of server instances. At the same time, customers are taking the consolidation opportunity to rationalize the number of middleware components needed to service a particular load. Middleware components most commonly run within a Java Virtual Machine (JVM) with an observed scale of 100 to 1000s of JVM instances and provide many opportunities for JVM instance consolidation. Hence, middleware virtualization provides an opportunity to consolidate twice – once to consolidate server instances, and, secondly, to consolidate JVM instances. This trend is far-reaching, because every IT shop on the planet is considering the cost savings of consolidation. One customer in the hospitality sector went through the process of consolidating their server footprint and at the same time consolidated many smaller JVMs that were less than 1GB heap. They consolidated many of these smaller 1GB JVMs into 2 categories, those that were 4GB, and others that were 6GB. They performed the consolidation in such manner that the net total amount of RAM available to the application was equal to the original amount of RAM, but with fewer JVM instances. They did all of this while improving performance and maintaining good SLAs. They also reduced the cost of administration considerably due to the reduced number of JVM instances they had to manage, and refined environment that helped easily achieve SLA.
Another customer, in the insurance industry, was able to achieve the same as the above customer, but additionally was able to over-commit CPU in development and QA environments in order to save on third party software license costs. On the other hand, sometimes we come across customers that have a legitimate business requirement to maintain one JVM for an application, and/or one JVM per a line of business. In these cases, you cannot really consolidate the JVM instances, as that would cause intermixing of the lifecycle of one application from one line of business with another. However, while such customers don’t benefit from eliminating additional JVM instances through JVM consolidation, they do benefit from more fully utilizing the available compute resource on the server hardware, that otherwise would have been underutilized in a non virtualized environment

Elasticity and Flexibility It is increasingly common to find applications with seasonal demands. For example, many of our customers run various marketing campaigns that drive seasonal traffic towards their application. With VMware, you can handle this kind of traffic burst, by automatically provisioning new virtual machines and middleware components when needed, and then automatically tear down these VMs when the load subsides. In addition, the ability to change updating/patching hardware without causing outage is paramount for middleware that supports the cloud era scale and uptime. VMware VMotion gives you the ability to move VMs around without needing to stop applicators and or the VM. This flexibility alone makes virtualization of middleware worthwhile when managing large-scale middleware deployments. One customer in the financial space, handling millions of transactions per day, used VMotion quite often to schedule their hardware upgrades without any time downtime. What otherwise would be a costly scheduled downtime to their business.

Performance Customers often report improved middleware platform performance when virtualizing. Performance improvements are partly due to the updated hardware that customers will typically refresh during a virtualization project. There is also some performance improvement due to the robust VMware hypervisor. A recent customer that reported a great level of performance provided the following testimony

“With our OrderExpress project we upgraded our Middleware Services, Commerce, Portal, WCM, Service Layer, DB2 Database; migrated from AIX to Linux; virtualized on VMware; moved the application into a three-tier DMZ; increased our transactions by over 150 percent; and added significant new capabilities that greatly improved the customer experience. Changing such a wide range of technology components at once was a huge challenge. However using VMware vSphere and additional architectural changes we were successful in improving performance by over 300 percent; lowered costs in the millions; improved security, availability, and scalability; and how we plan to continue evolving this application to maintain greater than 30 percent yearly growth.”

– Jeff Battisti, Senior Enterprise Architect at Cardinal Health

In this session, I will show some actual JVM and VM sizes for middleware components both small and large JVMs. Will also detail out GC tuning recipe that I have developed over the years,that has been shown to handle JVM heap sizes form 4GB to 88GB+, and higher. Of course the introduction of in-memory databases has driven the trend to have these larger JVMs and hence why we will discuss what is the best way to tune the JVM, VM, and the hardware platform they are deployed on.

I see the sizing question as the most commonly asked question with our customer base,and as a result I plan to focus on it during the session.

From Spring + Java to Spring + Akka - A Journey of Discovery

Actor based concurrency model is a paradigm shift. What is paradigm shift?

A change in the basic assumptions, or paradigms, within the ruling theory of science. A paradigm shift makes simple ideas hard to grok. Even though Actor model is a simple and revolutionary idea it becomes hard for programmers to see practical benefits and usage. Similarly, the Scala programming language brings a lot to the table in simplifying actor-based design, but comes with a new style of coding. One possible solution to this problem is to evaluate the new paradigm in terms of old paradigm. In this presentation we will take a working Spring based web application and gradually implement it using actors and Scala. We will be skeptical and suspicious of new ideas but at the same time we will be open minded. We will learn about actor based concurrency model using the knowledge of spring. At the same time, we'll learn best practices behind Actors, Scala and combining these with the Spring Framework.

Introduction to Spring Integration and Spring Batch

In this session you will learn what Spring Integration and Spring Batch are all about, how they differ, their commonalities, and how you can use Spring Batch and Spring Integration together.

We will provide a short overview of the Enterprise Integration Patterns (EIP) as described in the highly influential book of the same name. Based on these patterns, we will then see how Spring Integration enables the development of Message-driven applications. This allows you to not only modularize new or existing applications but also makes it easy to integrate with external systems.

This session will also introduce Spring Batch. Spring Batch addresses the needs of any batch process, be it complex calculations in large financial institutions or simple data migration tasks as they exist in many software development projects. We will cover what Spring Batch is, how Spring approaches the concepts of batch and how Spring handles scaling batch processes to be able to handle any volume of data.

You will also see how Spring Integration and Spring Batch maximize the reuse of the integration support provided by the core Spring Framework. In addition to providing a robust, proven foundation, this also flattens the learning curve considerably to all developers already familiar with Spring.

Getting started with Spring Data and Distributed Database Grids

Alternative data persistence approaches are all the rage these days. Transitioning our skill sets and legacy applications to these new and promising technologies though can be problematic. Spring Data is an exciting solution to persistence proliferation. It brings the flexibility and familiarity of the Spring Framework and adds the concepts of Repositories which allow developers to write their programs to using familiar methods such as save, update, delete, and dynamic finders.

In this presentation we will introduce Spring Data for GemFire and how it leverages your existing Spring Framework skills to create generic Spring style interfaces which will make it more efficient to transition to distributed data grids such as GemFire.

Whoops! Where did my architecture go?

When applications grow bigger, modularity becomes a key aspect regarding maintainability. Design decisions made in the early days are hardly discoverable in the codebase, inter-module dependencies grow a lot. The talk introduces means and approaches to connect logical architecture to the codebase. Beyond that we discuss patterns and best practices around general code organization, package structures to build a solid foundation for Java applications and in how far Spring can help creating loosely coupled components and dedicated points to extend applications.
