Azure Kubernetes Service (AKS) is a managed container orchestration service provided by Microsoft Azure. It simplifies the deployment, management, and scaling of containerized applications using Kubernetes, an open-source platform for automating application deployment and scaling. With AKS, users can easily create and manage a cluster of virtual machines that run containerized applications. It offers built-in monitoring, scaling, and security features, allowing developers to focus on building applications rather than managing infrastructure. This service is ideal for organizations looking to leverage the benefits of containers without the complexity of managing the underlying Kubernetes infrastructure.
