Microservices Vs APIs: Citing Clear Differences

Microservices and APIs are two fancy-sounding terms often used in the discussion of software architecture and integration.

In certain ways, both concepts play a crucial role in the creation and design of online applications today. In order to use microservices effectively, it’s necessary to understand how they’re used, as well as the distinctions between them. By doing so, you can gain a deeper understanding of the programs you use and sell, as well as have more productive conversations with developers.

Both play crucial roles in contemporary online applications, and given how they are employed, it almost seems as though the two names are interchangeable, albeit that isn’t quite accurate.

Throughout this blog, we’ll examine the slight overlap between both concepts and answer the long-standing question “what is the difference between APIs and microservices? ”

What is the Application Program Interface (API)?

In programming, an API refers to the part of an application that communicates with other applications. APIs are a set of protocols and methods that define how two applications share and modify data.

What are Microservices? 

Microservices refers to a style of software architecture that breaks down an application’s functions into smaller components called services. An application built this way follows a microservice architecture.

Difference between API and Microservices

Definition

 The API is a set of communication protocols and tools that can be used to build software. This is a set of predefined communication methods between various components. The APIs provide developers with access to applications. It is possible to view microservices as lightweight service-oriented architectures (SOAs) for developing software systems. A service is a component of a larger application that divides the functions of the application into smaller components.

Concept

 Microservices architecture is an architectural and organizational approach to software development that breaks large siloed components into smaller, more agile, and more manageable components. An API exposes the functionality of those components through interfaces. A distributed software system with loosely coupled components is particularly beneficial from APIs.

Function

Both concepts are distinct. A software system can be easily connected to, integrated with, and extended using APIs. It is easy to connect different applications to APIs since they provide a reusable interface. It is common for them not to be visible on the surface, instead, they operate under the hood and are called directly by other applications. An architecture based on microservices is usually based on business capabilities and priorities and is designed to solve big and complex problems.
