Description

This course will help you master the Java solution deployment process. You will find the essential elements of a JEE architecture there. Applications will be bundled and deployed to an application server. Finally, you will learn how to monitor these applications and analyze their performance.

Who is this training for ?

For whom ?

Integration architects, deployment managers, production architects, integrators, analysts and operations engineers.

Prerequisites

Basic knowledge of technical architectures (system, notions of deployment and integration, n-tiers).

Training objectives

Mastery of various Java EE/Jakarta EE architectures

Package Java EE / Jakarta EE applications and deploy them to an application server

Monitor and analyze the performance of Java EE / Jakarta EE applications
