The use of physical or virtual servers managed in clusters, with a focus on intensive server operations using Swarm and Slurm and the differences between them.
What is Swarm?
Swarm is a system that operates with a cluster mechanism published by Docker. This highly preferred system allows multiple dockers to communicate with each other and work synchronously, thus enabling an image to be created `n` times across multiple machines.
An additional advantage of this Cluster mechanism is that systems working in different compute pools or data centers can be added to the same cluster using the Swarm mechanism. When dockers located in different locations are added to the same cluster, an orchestration system emerges that can operate optimally without regard to location, continuing to function even if the electricity in one data center is cut off.
What is Slurm?
Slurm is a workload manager. It generally has similar functionalities to those provided by Swarm. One of the most important functionalities, the `Container` mechanism, can also be loaded into Slurm via a plugin. The main functionalities of Slurm are as follows.
- Management and prioritization of running processes.
- Providing framework support for managing and monitoring processes.
- Managing system resources for processes.
Differences Between Swarm and Slurm
Swarm is a much newer technology than Slurm and is more commonly used and known by new engineers as it is published by a large company like Docker. One reason for this is the efficiency of the documentation created by Docker. However, since Slurm is much older, it is more frequently used by senior engineers. The reason for this popularity is that the management of the system can be customized as desired and it can also be used without issues on older machines with old blades.
Therefore, when Swarm and Slurm are compared, while Swarm is a more user-friendly and quickly learnable system, Slurm is used more by professionals and is utilized in half of the world's top 100 computers. However, it should be noted that since Swarm is a new technology, it is still very open to developments, and as more people start using Swarm every day, its technology may evolve to surpass Slurm and establish its place as a sector standard in our computers in the upcoming years.
