Microservices with AWS Serverless

The popular microservice architecture pattern can profit significantly from the use of serverless resources even if it is not restricted to the conventional three-tier architecture.
Each component of the application is independent, decoupled, and deployed and operated separately with this design. All you need to build a microservice is an API created with Amazon API Gateway and functions that are then launched via AWS Lambda. These services can be used by your team to decouple and granularize your environment as needed.
The following challenges can generally be introduced by a microservices environment: repeated overhead for developing each new microservice; problems with optimizing server density and utilization; complexity of running multiple versions of multiple microservices concurrently; and proliferation of client-side code requirements to integrate with numerous microservices.
These issues become easier to resolve and, in some circumstances, even go away when leveraging serverless resources to build microservices. The serverless microservices pattern lowers the hurdle for each additional microservice to be created (API Gateway even allows for the cloning of existing APIs, and usage of Lambda functions in other accounts). With this method, optimizing server use is no longer necessary. Finally, to minimize integration complexity, Amazon API Gateway offers programmatically built client SDKs in a variety of widely used languages.
