TW的技术雷达分成四个象限：1. 技术；2. 工具；3. 平台；4. 语言

首先，来看技术，其中一个有趣的点就是应用服务器的终结，这是因为虚拟技术大行其道，不再需要一个应用服务器管理许多应用了，而是每个虚拟机一个应用了

A decade ago when memory was at a premium, application servers made a lot of sense. They were popular and useful as a mechanism to run and manage multiple applications on a shared server or cluster. These days applications are more often run on separate physical or virtual servers and the need for an application server is reduced. Consider evaluating server / application container end-of-life within your organization, and only use one if you benefit from the added complexity.

在Java应用中直接嵌入Servlet Container就是一个办法 

Embedding a servlet container, such as Jetty, inside a Java application has many advantages over running the application inside a container.

With the popularity of embedded HTTP servers increasing, so has the technique of out-of-container functional testing. That is writing tests at the boundary of the

system, using a mock container to provide both fast feedback and high coverage. Servers such as Jetty and tools like Plasma for the .Net platform can provide

a significant reduction in the time it takes to run your test suite.
