Kubernetes, the open-source container orchestration platform from Google, has revolutionized the landscape of modern application deployment and management. Its ability to automate and simplify the management of containerized applications has made it a go-to solution for enterprises seeking to accelerate their digital transformation journeys. This comprehensive guide delves into the intricacies of Kubernetes, exploring its key features, benefits, and best practices for successful implementation in an enterprise environment.
What is Kubernetes?
Kubernetes, also known as K8s, is a portable, extensible, open-source platform for managing containerized workloads and services, providing a consistent experience across on-premises, public cloud, and hybrid cloud environments. It orchestrates containers across a cluster of machines, ensuring high availability, scalability, and efficient resource utilization.
