A. Delving into Microservices
Why should you choose microservice architecture over traditional ones? What is the need for it? Is it really important to replace the traditional systems with this architecture?
Let’s answer the above questions to know their utility.
B. Microservices and their Uses
Let’s discuss the need for microservices. Microservice architecture is a distinctive approach to build software, using single-module functions. Every module has a well-defined interface that possesses specific features. This is how they are using them towards DevOps and testing.
DevOps teams are using them and creating agile solutions. Netflix, eBay, Twitter, PayPal, and leading companies have utilized them and evolved their monolithic or traditional architecture to modern.
Monolithic structures were built on a single system. There are many drawbacks associated with traditional architecture. Adding small changes in a system makes the entire system slow. Even it is very difficult to change the whole system. If you are planning to build and deploy a new version of the software, you will have to rewrite the whole software. Even if one wants to upgrade a single function, developers will have to work on the entire application.
Microservices overcome the challenges of monolithic or traditional architecture. They create modular services that execute specific functions. The independent deployable nature of the services can scale individual components. Further, there is no effect of one system on another. Services can be written in any language. Scalable and agile systems can be quickly developed. APIs are used to connect them. There are major benefits of using them. For example, they leverage RESTful and current ecosystems to provide customizable solutions. Testing of APIs is important in every respect. It validates data throughout the deployment of microservices.
C. Benefits of Microservices
There are many benefits to deploy microservices. Below are some major advantages of using them.
-
Deployment: It can be independently allocated. The deployment of a single microservice does not affect others.
-
Easy to Understand: Easy codes can be used during development as the functions are isolated and do not depend on any other.
-
Multifunctionality: Small services can be easily shared. For example, login or payment option.
-
Easy Isolation: Whenever any service fails, they can be easily deployed to isolate the system.
-
Minimum Risk: Steps can be taken for innovation without any risk. Read more about microservices
D. Features of Microservices
-
Individual Components: Software built of microservices can be tweaked. You can deploy, re-deploy or change the structure without the need for changing the whole structure. Earlier, tech-savvy used to re-deploy the whole system for making a small change in any service. This feature has eliminated the problems of remote calls, APIs and complexity.
-
Specialized in Business: Microservice architecture is built or created to meet business capabilities and priorities. Earlier, developers were focussed on technology layers and logic. Now companies are focussed on creating specific products, i.e., product-based solutions. Example, message bus.
-
Easy to Route: Microservices are similar to UNIX in functionalities. Firstly, a request is received. Secondly, processing occurs. Lastly, the responses are generated. Thus they are contrary to ESBs where advanced or upgraded systems are utilized in meeting business functions. They have endpoints that easily process information by utilizing logics and dumb pipes.
