How does Docker compare to similar solutions?

Kubernetes vs. Docker: Friend or Foe?

Even if Kubernetes and Docker work together wonderfully, there is competition when it comes to Swarm. Docker handles both solutions and can even switch back and forth between them, but Docker Swarm and Kubernetes do cannot be combined. Therefore, users are often faced with the question of whether to rely on the very popular Kubernetes or use the Swarm, which belongs to Docker.

The structure of the two tools is fundamentally very similar - only the names of the individual aspects change. The purpose of use is also the same: Manage containers efficiently and through intelligent scaling ensure that resources are used as sparingly as possible.

Swarm reveals advantages in the installation: Since the tool is an integral part of Docker, the transition is very easy. While with Kubernetes you first have to set up the orchestration, which is admittedly not particularly complex, everything is already there with Swarm. Since you are most likely already working with Docker in practice, you do not need to familiarize yourself with the peculiarities of a new program.

But Kubernetes shines with its own GUI: The dashboard belonging to the application not only gives you a very good overview of all aspects of the project, but can also perform numerous tasks. Docker Swarm, on the other hand, only offers such convenience through additional programs.

Kubernetes can also score points for its range of functions: While Swarm for the Monitoring and keeping a log If additional resources are required, these tasks are already provided in Kubernetes and corresponding functions are part of the repertoire.

The main benefit of the two programs, however, is that Scaling and ensuring availability. It is said that Docker Swarm is generally better in terms of scalability. The reason for this is the complexity of Kubernetes, which leads to a certain clumsiness. On the other hand, the complex system ensures that automatic scaling is better with Kubernetes. Another great advantage of Kubernetes is that it monitors the condition of the containers at all times and compensates for a failure directly.

For this, Swarm cuts the Load balancing better: The even distribution of the load is a matter of course with Swarm. With Kubernetes you have to take a little detour for load balancing. There, deployments must first be turned into services in order to benefit from the load distribution.
