My apologies in advance if this has been already discussed in the group. I am looking for experiences of the community, any nitpicks, etc.
Currently we are using standalone Tomcat version (9.x) to host a web applications which are essentially hosting REST APIs. We plan to move to micro services model where each web application (logical unit of related APIs) will be hosted as a different process. With this mind, I wanted to evaluate the embedded version of Tomcat. 1. Is there any guidance around when to use what? 2. Are there any feature disparities between standalone Tomcat and embedded version? We have fairly extended Tomcat classes for use cases like automatic certificate renewal, not having to mention is plain-text password in server.xml for key stores, hooking in custom security provider (for FIPS) for Tomcat JVM. etc. So we ideally wouldn't want to lose any of such capabilities when we move to the embedded version. 3. Currently, we have written a Windows SCM service wrapper and manage our Tomcat JVM via that (on Windows). Would there be any issue with embedded Tomcat if we want to have SCM service wrapper? 4. How is the upgrade process different for embedded version? Currently, we ship Tomcat with our product and have a well-defined process to upgrade Tomcat even with older versions of our product deployed in customers' environment. 5. Externalizing the configuration (like we can do that via web.xml, server.xml, context.xml) - any issues, limitations here? 6. Any differences with resource usages (e.g. heap)? Any help is greatly appreciated. Thanks, Amit
