Kubernetes
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It provides a framework for running distributed systems resiliently, handling tasks like load balancing, storage orchestration, and self-healing. Originally developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF), it is widely used in cloud-native environments.
Developers should learn Kubernetes when building scalable, microservices-based applications that require automated deployment, scaling, and management across clusters of hosts. It is essential for DevOps and cloud engineering roles, particularly in production environments where high availability and resource efficiency are critical, such as in hybrid or multi-cloud setups. Use cases include managing containerized web apps, batch processing jobs, and stateful applications like databases.
