Why has Kubernetes become more popular than Docker Swarm, even though both are orchestration systems?

Kubernetes became more popular than Docker Swarm for several reasons:

• Scalability and flexibility: Kubernetes was originally designed to manage large clusters and complex scenarios, whereas Docker Swarm is geared towards simpler cases.
• Rich functionality: Kubernetes offers more advanced features such as automatic scaling, self-healing, configuration and secret management, and complex deployment strategies.
• Community and ecosystem support: Kubernetes is supported by major companies and has a large community, numerous tools, and integrations.
• Standardization: Kubernetes has become the de facto standard for container orchestration, making it easier to hire specialists and integrate with cloud providers.

While Docker Swarm is easier to set up and use, its functionality and scalability options are limited compared to Kubernetes.
