Which Azure service allows for the deployment and management of applications composed of microservices?

The Azure service that specifically allows for the deployment and management of applications composed of microservices is Azure Service Fabric. This platform provides a robust environment that facilitates the development, deployment, and management of microservices-based applications. Service Fabric supports both stateless and stateful microservices, and it helps manage the lifecycle and scaling of these services seamlessly.

Azure Service Fabric addresses the complexities of microservices architecture by providing features such as service discovery, load balancing, health monitoring, and automatic scaling. It also allows developers to create and run services in various programming languages, making it versatile for different application needs.

While Azure Kubernetes Service is also designed for managing containerized applications, including those built on microservices, it focuses primarily on the orchestration of containers. Azure App Service is generally aimed at web applications, mobile apps, and API services rather than specifically managing microservices. Azure Logic Apps targets workflow automation which leverages a visual designer for building automated workflows rather than managing microservices architectures.

In summary, Azure Service Fabric is explicitly tailored for microservices, offering comprehensive management capabilities and a mature platform for developers working within that architecture.
