Containerize your stuff.

It was never so straightforward. If you are having difficulty, you can find assistance in Nigel Poulton's books and courses. These can be accessed on CloudGuru, Udemy, or Pluralsight. As of 2023, this app server and backend engine run within Docker containers.

Dockerization, or containerization, offers a myriad of advantages.

Those make applications more efficient, scalable, and portable. Here's why apps are often considered better when Dockerized:

  1. Portability: Docker containers encapsulate an application and its dependencies, ensuring consistency across various environments. This portability allows developers to create applications that run seamlessly on different machines, eliminating the notorious "it works on my machine" problem.
  2. Isolation: Docker containers isolate applications and their dependencies from the underlying infrastructure. This isolation improves security by reducing the attack surface and mitigating compatibility issues, as each container operates independently.
  3. Efficient Resource Utilization: Docker containers share the host OS kernel, which minimizes resource overhead. This leads to more efficient utilization of system resources, allowing for a higher density of applications on the same infrastructure. Scalability: Docker's lightweight nature makes it easy to scale applications horizontally by deploying additional containers. This scalability is particularly beneficial for microservices architectures, where components can be independently scaled based on demand.
  4. Rapid Deployment: Docker containers can be quickly created, started, and stopped. This agility streamlines the development and deployment process, facilitating faster release cycles and enabling continuous integration/continuous deployment (CI/CD) practices.
  5. Version Control and Rollbacks: Docker enables version control for both applications and their dependencies. This ensures that the environment remains consistent across different stages of the development lifecycle, and rollbacks can be easily executed if issues arise.
  6. DevOps Facilitation: Docker promotes collaboration between development and operations teams by providing a standardized platform. Developers can work in an environment identical to the production setup, reducing friction during the transition from development to deployment.
  7. Resource Efficiency: Docker's containerization technology allows for better resource utilization compared to traditional virtualization. This efficiency results in faster startup times and improved performance.
