Kubernetes
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It groups containers into logical units called pods for easy management and provides features like load balancing, storage orchestration, and self-healing capabilities. Originally developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF), it is the de facto standard for running containerized workloads in production environments.
Developers should learn Kubernetes when deploying and managing microservices-based applications at scale, as it simplifies operations like rolling updates, service discovery, and resource allocation across clusters. It is essential for cloud-native development, enabling portability across on-premises, hybrid, and multi-cloud environments, and is widely used in DevOps and site reliability engineering (SRE) roles to ensure high availability and efficient resource utilization.
