title: Application Server to Container Migration
description: >-
  Complete workflow for migrating Java applications from traditional application
  servers (WebLogic, JBoss, Tomcat) to containerized deployment using Docker
  and AWS cloud platform. Covers containerization, orchestration, and cloud-native deployment.
