Deploying a Packaged Java Application on an AWS EC2 Instance
This document explains how build tools and package managers automate software compilation, dependency management, testing, packaging, and artifact publication.
It also explains how these tools integrate into CI/CD pipelines, containerized deployments, and modern DevOps workflows.
Software is not delivered as source code. It is delivered as a deployable product.
Before an application reaches production, it must pass through multiple engineering stages:
Build tools and package managers exist to automate these processes in a predictable, repeatable, and scalable manner. They transform source code into deployable artifacts while ensuring consistency across developer workstations, CI/CD systems, testing environments, and production infrastructure.
From a DevOps perspective, build tools are not simply developer utilities, they are critical components of the software delivery lifecycle.
Imagine a software application consisting of:
