There are plenty of examples of basic Dockerfile based builds out there, but a production application requires a bunch of different things, such as reproducibility, hardening, health checks, static analysis - and ideally still be quick to build.
Spring MVC abstracts the Java servlet container implementation away from you almost completely, this allows you to migrate from Tomcat quite easily.

One part of doing C++ the right way is using automatic variables for everything you possibly can. However at some point in your C++ endeavours, you’re likely to be using a C API of some sort, with explicit method calls to manage lifecycles, which can make this more difficult. My work at Canonical has involved talking to lots of these sorts of APIs, many of them based on GNOME’s Glib. To make life easier, I have created a set of easy to use wrappers to manage the lifecycle Glib and GObject objects.
