Microservices are a software engineering and architecture methodology in which the software is composed of de-coupled componentized services that communicate via well-defined interfaces over an API.

Setup AWS Lambda Function as a Kinesis stream consumer. The stream will trigger the Lambda Function to run for each record sent to the Kinesis stream.

Microservices architectures allow applications to scale, grow, pivot, and innovate much more efficiently than other architectures.

What’s the difference: Monolithic v Microservices

Monolithic architectures typically indicate that all processes are tightly coupled and can only run as a single service and usually on that same server. Expanding the codebase and product offering becomes increasingly complicated dues to the inter woven functionality. Monolithic applications need to have an indepth infrastructure monitoring &amp; maintenance and DevOps plans in place to keep access and performance stable and the application grows.

Microservices architecture designs allow an application to be built with independent components that run each application process individually as its own service. Services communicate via a well-defined interface through a, typically internal, API layer. Microservice services are built for business capabilities by taking into account the needed business logic and each service performs an individual function or logically grouped functionalities. Since they are independently run, services can be individually updated, deployed, reverted, and scaled to meet current and future demand of an application.
