API microservices architectures help design software applications as small, independent, and self-contained services enabling the functionality of a larger application.
The fast pace of the digital-world, means businesses have to continually explore ways to improve their systems and processes. API microservices architecture is a game-changing approach that can help businesses improve their systems and processes. API microservices architectures help you design software applications as small, independent, and self-contained services. These independent services work together to enable the functionality of a larger application. Developers can use API microservices architecture to build scalable and resilient apps, which leads to greater efficiency and agility.
This article provides an in-depth analysis of API microservices architecture, including its core components, best practices, and essential considerations to help businesses harness its full potential.
Many wrongly assume a microservice is an API. A microservice is a type of architectural pattern. The purpose of a microservice is to build an app as a collection of small, standalone services. APIs are a set of tools, protocols, and standards used for interfacing with a service. APIs are used to interact with those standalone microservices. Microservices and APIs, while being closely linked, are not the same.
When planning a microservice, ensure that the following layers are considered in your design plans and threat model:
Resource or Data Model Layer: Defines the data or resources exposed through the API. It includes the data structure, data types, and relationships between data elements.
Control Layer: Specifies what operations can be performed on resources or data exposed by the API. Includes CRUD operations (Create, Read, Update, Delete), search, filtering, sorting, and pagination.
Logic Layer: Implements business logic and rules that determine the behavior of the API. This layer includes input data validation, access control, security, error handling, and other custom processing.
Service Layer: Provides the interface between APIs and the underlying system or app. The service layer includes the protocol, data format, authentication, and other technical aspects of communication between the client and the server.
API microservices architecture is an excellent approach to building complex software systems.Following the best practices and key considerations outlined, can help you maximize the power of API microservices architecture and build robust, scalable, and maintainable apps. By putting the right tools and processes in place, you can fulfill the full potential of API microservices architecture and help to improve your app's capability.
