Migrating JEE Applications to SpringSource tc Server

The migration decision process

In this white paper, we will be discussing an important trend in IT development and deployment architectures: the evolution from JEE Application Servers to lighter weight Java containers. As evidenced by the growing popularity of Tomcat server - according to Evans Research, Tomcat is in use at 68 percent of all organizations (50 percent of which are built in Spring), making it the most widely deployed application server on the planet - many IT organizations have been re-thinking their commitment to commercial JEE application servers. This is due to challenging business environments that drive the need for more cost-effective application architectures and, just as important, the trend toward the use of more lightweight and efficient mechanisms for application development. This also becomes even more important as organizations begin to consider building applications for deployment into the cloud future. When IT organizations talk about "migrating" their applications, they generally are focusing on one or more of three distinct situations. These are:

  • Moving existing applications (or portions of applications) off of JEE servers and onto lightweight, modular, horizontally scalable container infrastructures
  • Expanding access to existing JEE applications by adding services layers built in lightweight containers.
  • Transitioning new development away from JEE application servers and focusing on lightweight containers

We will be focusing primarily on the migration of existing JEE applications to the SpringSource tc Server, which is an "enterprise ready" web application server built on top of standard Apache Tomcat and optimized for the Spring Framework. There are many excellent reasons to consider moving applications off of commercial JEE servers. While we are focusing on the JEE application migration process, many of the business and technical decision factors apply equally well to the second and third situations as well.

The IT Manager considering migrating applications from their commercial JEE servers has a number of important things to determine before embarking on the process. It is extremely important to clearly understand the objectives of the migration in order to properly assess the benefits, and costs, of such a program.

In this white paper, we focus on the migration decision processes for determining whether to migrate your applications or portions of your applications from commercial JEE servers to SpringSource tc Server. Many of these decisions should be based on business factors, although there are also significant technical opportunities and challenges to address.
