containers, but also required by any software. For example, add a security policy. What is "lightweight "? Since it is "light", it is more "heavy. A typical example of "heavy" is EJB, which provides a series of "Heavyweight" enterprise-level services and allows you to develop good components.Integrates enterprise-level services provided by EJB containers, such as JTA. Now that we have a service container "yes, why do we still need" lightweight? This

ObjectiveThe company has been using the traditional Tomcat to drop the war package architecture system, with the increase of the project, the number of servers, the need to spend a lot of time on different server system environment issues. In order to advance the technology and the operational efficiency of the work, the author introduced the Docker container deployment mode, through the Gitlab+jenkins+harb

storage, retrieval, and integration of data. Therefore, it is necessary to split these services into their own containers through design and deployment. If an application can be split into more distributed components, the more choices the application extends. However, the more distributed components, the higher the complexity of management. Step 2: Select an underlying image When performing an application migration, try to avoid the practice of top

A: Several people cloud is triggered by monitoring the alarm to expand the elastic, such as monitoring the return time of the interface, container memory utilization, etc. Q: What kind of management method do you use for environmental

Describes several SSIS deployment methods and ssis deployment methods.Introduction If you have developed a good SSIS package and can run it perfectly locally, each task will be highlighted with a green pass sign. In this case, you need to publish the package to a server and configure it properly to make it run at a specified time. As developers, we may not be able to do this directly in the production envir

1. Tomcat is the Apache Support Java Web Application Server, because of its excellent stability and rich documentation, a wide range of users, thus in the open source area has been the most popular. - 2. JBoss, as a Java EE application Server, is not only a servlet container, but also an EJB container that is welcomed by enterprise developers, making up for the flaw that Tomcat is just a servlet
