Which Azure service provides container orchestration and scalable deployment for microservices?

Azure Kubernetes Service (AKS) is the correct answer because it is a managed Kubernetes offering that provides container orchestration, enabling you to deploy, scale, and manage containerized applications like microservices efficiently. AKS handles the underlying infrastructure, allowing you to focus on your applications. Azure Functions is a serverless compute service for event-driven, short-running code, not primarily for container orchestration. Azure App Service is a platform-as-a-service (PaaS) for hosting web applications, APIs, and mobile backends, but it doesn't offer the same level of container orchestration as AKS. Azure Virtual Machines provide infrastructure-as-a-service (IaaS) for running virtualized servers, which would require manual setup and management of container orchestration tools.
