Aws Microservices Architecture Example

In this tutorial you will use the lambda console to create a lambda function and an amazon api gateway endpoint to trigger that function.

Aws microservices architecture example.

The aws architecture center provides reference architecture diagrams vetted architecture solutions well architected best practices patterns icons and more. Aws provides a ton of managed building blocks for handling every aspect of microservices implementation and provides all the tools needed to replace these components with open source alternatives should you have the necessary expertise at hand and be able to. It is a software engineering approach that focuses on decomposing an application into single function modules with well defined interfaces. You will be able to call the endpoint with any method get post patch etc to trigger your lambda function.

We chose amazon web services aws as our cloud provider because it provided us with the greatest scale and the broadest set of services and features. Monolithic architecture the entire node js application is run in a container as a single service and each container has the same features as all other containers. Microservices is a service oriented architecture pattern wherein applications are built as a collection of various smallest independent service units. Figure 1 depicts a reference architecture for a typical microservices application on aws.

Source in 2009 netflix began the gradual process of refactoring its monolithic architecture service by service into microservices. These services are owned by small self contained teams. When the endpoint is called the entire request will be passed through to your lambda function. Microservices architectures make applications easier to scale and faster to develop enabling innovation and accelerating time to market for new features.

This expert guidance was contributed by aws cloud architecture experts including aws solutions architects professional services consultants and partners. I hope that you have read my previous blog on what is microservices that explains the architecture compares microservices with monolithic and soa and also explores when to use microservices with the help of use cases. Organizations are quickly moving towards microservices architecture hunting for professionals with microservices certification. A central idea of a microservices architecture is to split functionalities into cohesive verticals not by technological layers but by implementing a specific domain.

Microservices are an excellent choice for building running and updating resilient and highly scalable applications. For example you can use constraints to place certain microservices based on instance type or instance capability such as gpu powered instances.
