Docker containerization is a popular technology that allows developers to package their applications with all their dependencies, run-time environments, and code into a single unit, which can be easily shipped and deployed on any machine. However, as the number of containers grows, issues like scaling, replication, fault tolerance, and container communication become complex challenges. To overcome these limitations, container orchestration tools are needed to manage multiple containers across a fleet of machines. The presentation discusses three popular container orchestration tools: Docker Swarm, Kubernetes, and Apache Mesos. Each tool has its strengths and weaknesses, and the choice of which one to use depends on specific requirements and needs. Docker Swarm provides simplicity and ease of use, while Kubernetes offers more concepts, abstraction, stability, and maturity. Apache Mesos is a resource allocation manager that can manage both Docker and non-Docker jobs, providing flexibility and scalability. The presentation concludes by emphasizing the importance of choosing the right orchestration tool based on specific needs and requirements.
