Aws Microservices Architecture Example

Microservices is a service oriented architecture pattern wherein applications are built as a collection of various smallest independent service units.

Aws microservices architecture example.

It is a software engineering approach that focuses on decomposing an application into single function modules with well defined interfaces. The aws architecture center provides reference architecture diagrams vetted architecture solutions well architected best practices patterns icons and more. 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 are an architectural and organizational approach to software development where software is composed of small independent services that communicate over well defined apis.

We first describe different aspects of a highly scalable fault tolerant microservices architecture user interface microservices implementation and data store and how to build it on aws leveraging container technologies. These services are owned by small self contained teams. In many cases design patterns of the twelve factor app are leveraged for microservices. Organizations are quickly moving towards microservices architecture hunting for professionals with microservices certification.

For example you can use constraints to place certain microservices based on instance type or instance capability such as gpu powered instances. When the endpoint is called the entire request will be passed through to 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. 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.

Microservices architectures make applications easier to scale and faster to develop enabling innovation and accelerating time to market for new features. A central idea of a microservices architecture is to split functionalities into cohesive verticals not by technological layers but by implementing a specific domain. You will be able to call the endpoint with any method get post patch etc to trigger your lambda function. This expert guidance was contributed by aws cloud architecture experts including aws solutions architects professional services consultants and partners.

In this tutorial you will use the lambda console to create a lambda function and an amazon api gateway endpoint to trigger that function. Figure 1 depicts a reference architecture for a typical microservices application on aws.
