Abstract: A network service may be supported by a software application that is executed by multiple computer servers, such as servers that are maintained as part of a server pool. To migrate to a container-based platform, the software application is containerized to create a container image. A container cluster is then created based on the container image. The container cluster includes one or more executing containers, each of which performs the functions of the software application. The container cluster is then added as a member of the server pool to receive a portion of any network requests for the network service. Computer servers of the server pool may then be removed gradually, over time, to let the container cluster gradually assume responsibility for responding to network requests.

Abstract: A network-based services may be supported by a single, monolithic application that is responsible for responding to many different types of requests. The monolithic application may be replaced with multiple microservices that correspond respectively to multiple operations supported by the monolithic application. Each microservice is designed to honor the same application programming interface (API) contract that the monolithic application uses for the corresponding operation. Migration to a microservices-based architecture can be performed gradually, over time, by appropriately configuring a number of API gateways to redirect certain requests, for certain operations, to appropriate microservices. For each operation and corresponding microservice, the number of APIs configured in this manner can be increased until all requests for the operation are being directed to a corresponding microservice.
