Program
The Java platform has reached maturity at the server level with the JEE standard. The JEE platform has been in existence for several years now and its reliability is proven. It has demonstrated its robustness for large-scale applications needing to offer high levels of availability. After a presentation of the components of the JEE standard, this seminar analyses the essential points related to designing and deploying a multi-tier transactional JEE architecture. After this course, the participants will be able to determine which the architectures correspond best to their needs in terms of performance and availability. They will also be able to evaluate the different commercial and Open Source products on the market.
