Azure App Service: Build, deploy, and scale web apps on a fully managed platform. Quickly build, deploy, and scale web apps created with popular frameworks .NET, .NET Core, Node.js, Java, PHP, Ruby, or Python, in containers or running on any operating system. Meet rigorous, enterprise-grade performance, security, and compliance requirements by using the fully managed platform for your operational and monitoring tasks; Azure Kubernetes Service: Simplify Kubernetes management, deployment, and operations. Fully managed Kubernetes container orchestration service on Microsoft Azure.
Azure App Service belongs to "Platform as a Service" category of the tech stack, while Azure Kubernetes Service can be primarily classified under "Containers as a Service".
