Upgrading the software stack on a hosting infrastructure (e.g. the OS, the DBMS or the Servlet Container) is inevitable, and that it might well generate undesired side-effects in the hosted applications.
For instance, a new version of the DBMS might not support some special features your backend relies on. Even worse, a new version of the Operating System might not support an open-source library your backend depends on. In such cases, locating and fixing the problem can be hard and very expensive.
The Livebase subscription not only includes regular upgrades of the software stack on the Hosting Infrastructures, but it also guarantees that a new version of the platform is contextually released, capable to automatically rebuild all the Cloudlets in order to make them compatible with the new software stack.
