 [AWS App2Container](https://aws.amazon.com/app2container/) (A2C) is a command line tool that containerizes your applications. It automatically generates a container image configured with the correct dependencies, network configurations, and deployment instructions for Amazon ECS or Amazon EKS. A2C can  detect a .NET 8 runtime version and containerize the application using the corresponding runtime base images.
 
-[AWS Microservice Extractor for .NET](https://aws.amazon.com/microservice-extractor/) is an assistive tool that serves as an advisor to assess and visualize monolithic code, and recommend microservice candidates using artificial intelligence and heuristics. It also serves as a robotic builder to simplify microservices extraction. Microservice Extractor supports analyzing .NET 8 applications for visualization, grouping, and extraction. With its integrated strangler-fig porting capability, you can also use Microservice Extractor to break down a large .NET Framework-based application with hundreds of projects and thousands of classes into manageable groups and port those directly to .NET 8.
