Kubernetes is a container orchestration system that automates the deployment, scaling, and management of containerized applications. Originally developed by Google, Kubernetes has become the de facto standard for managing container clusters in production environments. It allows for distributing workloads, restarting failed containers, and balancing traffic among multiple instances, ensuring high availability and efficiency. With a declarative architecture, teams can define the desired state of their applications and let Kubernetes handle the implementation. Its use is fundamental for companies adopting microservices and looking to operate at scale, as it simplifies administration and improves application resilience.
