Software development has never been more dynamic—or more demanding. Users expect uninterrupted service, businesses require faster innovation, and the technology ecosystem is more diverse than ever. Traditional methods of application deployment are simply not equipped to handle these challenges with the required agility. Traditional monolithic applications typically group all parts of an application—frontend, backend, and database—into a single unit, often leading to challenges in scaling and maintenance. In this approach, all application components—such as the user interface, business logic, and database—were bundled into a single, unified codebase. While this method worked for smaller projects, it became increasingly difficult to scale, maintain, and deploy as systems grew in complexity. In contrast, modern microservices architectures break down applications into smaller, independent services that communicate via APIs. Each service can be developed, deployed, and scaled independently, promoting flexibility. However, managing multiple services introduced a new challenge: how to deploy and maintain these components efficiently. Containerization plays a crucial role here, providing isolated environments for each microservice and enabling the development and deployment of complex applications with ease.
