Microservices are achieving popularity in the market as organizations move in the direction of building complex and larger applications that can be segregated and handled as a compilation of smaller services. There has been an increasing number of people hoping to upgrade their traditional monolithic systems into a sequence of single independent microservices. The basic question that strikes your mind is, Which is the best language to be used while developing microservices for your next project?
You can use different technologies dependent on what best serves the purpose of your microservices. Here we will see some programming languages that have the features and libraries, which will help you in getting your job done. But before that, let us see, what is microservices architecture?
What is Microservices Architecture?
Microservices architecture is a development methodology wherein you can fragment a single application into smaller services, each one executing in its own process and interacting with lightweight mechanism. The microservices are developed around business capabilities, which are independently deployable with automated deployment mechanism. The microservices architecture needs an absolute minimum of the management of these services, built-in various programming languages and uses various data storage technologies.
Reasons to Migrate to Microservices Architecture-
- In a monolithic architecture, for a large application, it is difficult to penetrate the complexity and tough to deal with the code.
- Applications require broad manual testing so as to grasp the effect of alteration.
- The whole application requires to be deployed again even for a small change.
- Large applications with monolithic architecture can slow down the start-up time.
Benefits of Microservices-
1. Easier Process Adoption–
With a microservices architecture, new technology, and process adoption become easy.
2. Small Modules–
It is simple for developers to develop and maintain because the application is broken into smaller parts.
3. Independent Scaling –
Every module in microservices can scale freely through-
-X-axis scaling – by cloning with more memory Or CPU
-Z-axis scaling – by size using sharding
4. DURS –
Each service in microservices architecture can be autonomously DURS (Deployed, Updated, Replaced and Scaled)
5. Unaffected-
Even the failure of a single module won’t influence the rest of the app.
Microservices ensure increased the autonomy of development teams (speed to market), better fault isolation (reliability), reusability and scalability.
Criteria for Choosing a Technology for Microservices-
With microservices, you can build a reliable platform to enhance the business while exploiting the advantages of various languages. You can use various technologies or languages for various services, but it doesn’t mean it is effective.
The microservices architecture accompanies many operational overhead; thus including a diverse programming language on top of that can exponentially raise that performance overhead. To decrease that, you should standardize your microservices tech stack by selecting the programming language according to your business needs. Let’s see the criteria to evaluate the programming language for microservices development:
- Highly observable
- Support for automation
- Consumer-first approach
- Independent deployment
- Modeled around business domain
- Decentralization of components
- Support for continuous integration
Top 5 Technologies for Microservices-
Microservices can be implemented with a group of frameworks, versions, and tools. Java, Python, C++, Node JS, and .Net some of them. Let us know about the languages that support microservices development in detail:
