Frequently Asked Questions about Kubernetes
What is Kubernetes?
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications across clusters of machines.
What are the primary use cases for Kubernetes?
Orchestrating containerized applications. Automating deployment, scaling, and rollback. Managing microservices architectures. Providing service discovery and load balancing. Running hybrid or multi-cloud workloads
What are the strengths of Kubernetes?
Highly scalable and resilient. Cloud-agnostic and portable. Strong ecosystem with tooling and extensions. Declarative and automated operations. Active community and enterprise support
What are the limitations of Kubernetes?
Steep learning curve for beginners. Operational complexity at scale. Debugging issues can be challenging. Resource-intensive compared to lightweight orchestrators. Requires good understanding of networking and storage concepts
