In the current age, almost all IT companies are moving their infrastructure and architecture to cloud and DevOps trends. We can see cloud computing, containerization and orchestration solutions everywhere. When talking about cloud-native, it is hard to ignore names like Docker and Kubernetes, which have revolutionized the way we create, develop, deploy and ship software at scale.
Docker removed an issue called “dependencies”. It makes it extremely easy for organizations to run applications in a similar environment without any issues of dependencies or OS as it provides its own OS libraries.
The Development Team and the testing team now have the same system running on Docker containers. It allows to “Build, Ship, and Run applications, Anywhere.” If it works on your machine, it will work on others’ machines. It packages up the services comprising an application and makes them portable across different compute environments, for both developers, testers, and production uses.
While Docker provides an open standard for packaging and distributing containerized applications, there are problems that need to be tackled down.
- How containers can be coordinated and scheduled?
- How to seamlessly upgrade an application without interrupting the services?
- How to monitor the health of the application and know when something goes wrong and seamlessly restart it?
Then, the solution comes as a Container Orchestration tool called – Kubernetes. It can handle the container management responsibilities like container deployment, scaling, healing, and load balancing of containers. Docker helps us to create containers, and Kubernetes allows us to manage them at runtime.
