Jakarta EE has several profiles, each focusing on different subsets of the overall EE platform. Web Profile is one of those subsets that focuses on the Web aspects of Jakarta EE. For example, Tomcat is more of a Web Profile stack (I don't know it Tomcat officially supports it or not) compared to the full boat EE containers like Glassfish, Websphere, etc. Jakarta Concurrency (which is essentially portable access to container managed thread pools and other similar resources) was originally part of the full EE specification. Now they've moved it to the Web Profile so it can be used in those containers that do not support the entirety of Jakarta EE.
