All Big Giants, including Netflix, Uber, eBay, Amazon, Twitter, PayPal, and more, have already consummated value for money after using a microservices architecture. You would be surprised to know that Netflix, the fastest-growing company is one of the earliest adopters of Microservices architecture. Uber, initially used monolithic architecture, but soon shifted to microservices. Do you know the reason why? To find out the answers to all of these questions, including, “why should you use Microservice architecture for your software development?”, Keep reading this blog.
Microservices is a development technique, a variable of Service Oriented Architecture(SOA), that assists in developing large applications where you can arrange and divide services into small independent chunks depending on the domain. In a microservices architecture, the services are fine-grained, and the protocols are lightweight.
The tangible benefits of adopting this microservice architecture are, increase in scalability, modularity, availability, agility, flexibility, and others. For the very obvious reasons, the microservice approach is getting maximum traction these days. Ever since the term came into the picture, it is laying the foundation of resilient software development.
Microservices is helping developers to understand the complex application process better and deliver it faster after effective testing. To be honest, you just can not ignore this whole buzz going around the microservices architecture at all, can you?
Before we deep dive into the microservice architecture, it would help if we know the details of the contrary approach, which is monolithic architecture.
Wikipedia’s definition of monolithic architecture,
In software engineering, a monolithic application describes a single-tiered software application in which the user interface and data access code are combined into a single program from a single platform.
It is a traditional way of building applications usually comprises of a client-side user interface, server-side architecture, and a database. The architecture has a huge codebase but with no modularity. This means, if you wish to make any changes in the codebase then, you will have to go through the whole stack of code and make changes in it.
The monolithic approach uses a three-tier architecture, which is given below.
Business Layer: It is the middle layer where the data processing takes place for making logical decisions and calculations.
Data Access Layer: This is the final layer from where the data is passed to the user. In the Data Access Layer, the information is stored and retrieved from the database.
In simple words, the client query is received through the application, passes through the business layer for logic execution, stored in the Data access layer, and presented to the user in the Presentation layer. This traditional approach of software development was welcomed until the demand rose for continuous delivery. It proved to be inefficient in handling the continuous delivery demand.
