A healthcare app team wants to focus solely on writing application code and avoid managing servers. Which Azure offering should they choose?

Azure App Service (PaaS) is the correct choice because it's a fully managed platform that allows developers to deploy, manage, and scale web apps without worrying about the underlying infrastructure. This aligns perfectly with the team's goal of focusing solely on code and avoiding server management. Azure Kubernetes Service (AKS) still requires some cluster management and configuration, which goes beyond just writing application code. Azure Virtual Machines (IaaS) require significant server management, including operating system patching, security, and networking. Azure Blob Storage is an object storage solution, not a platform for running applications, and therefore irrelevant to the team's need to host an application.
