You are correct to assume that you cannot replace Jetty with a different web server.
Jetty is a well-known open-source project backed by the Eclipse Foundation, making it a reliable choice for Mendix. It has a very active community that is dedicated to maintaining high performance and resolving security issues quickly. Additionally, it is a lightweight web server with a low memory footprint, specifically designed to be embedded into Java servers rather than functioning as a standalone server, which aligns perfectly with our needs.
Mendix is designed to be as agnostic as possible to the technology choices. This abstraction allows developers to focus on building applications without worrying about the underlying infrastructure. As technologies advance, the Mendix runtime can be adapted accordingly. This approach is part of our commitment to ensure that Mendix applications remain reliable and future proof indefinitely.
