The 9 Best Programming Languages to Build Microservices Architecture

Microservices have become WIDELY POPULAR as companies aim to expand their business capabilities and services.

With such desires among entrepreneurs, more complex systems are required to run applications.

Unlike the traditional monolithic architecture, microservices can house and operate several functionalities under one UI (user interface).

Programmers can develop microservices with these 9 best programming languages and frameworks:

1.) Native iOS Swift

Swift is a native programming language in iOS, macOS, and other Apple applications. So, if you plan on developing microservices on these platforms, Swift is the easiest way to go.

Swift is a good language for microservices, given that it offers modern features and performs FASTER than other frameworks.

Additionally, this programming language can handle large connections (which is highly required on microservices) and has low memory footprints. Hence, it doesn’t require many resources to fit into existing projects.


  • Easy to code and contains modern features

  • Faster than existing languages

  • Handles large connections

  • Low memory footprints


  • Limited cross-platform support

  • Doesn’t support earlier iOS versions

2.) Native Android Kotlin

It will be easier for you to learn and adapt to this language since they have similar intricacies.

This further means it can operate with famous Java libraries and systems like Spring Boot, Jackson, and Reactor.

It’s also a good language for microservices development because it allows programmers to utilize modern idioms that can imply the method of developing microservices.

Additionally, Kotlin has first-class support from Google in the Android ecosystem. Hence, it’s guaranteed to stay a mainstream language for a long time.


  • Interoperability with Java, like Spring Boot

  • Utilize modern idioms

  • First-class Google support


  • Limited learning resources

  • Slow compilation speed

3.) Flutter

Flutter is a platform or framework rather than a language. Google created it as an open-source programming kit to develop native-looking applications for iOS and Android.

It has grown in popularity over the years because it can be used to develop apps quickly and easily for several operating systems.

Primarily, it uses Dart as its programming language in cross-platform development. Its operability is also SIMILAR to Java, JavaScript, and TypeScript, so you won’t have any difficulties adapting to it.

With Flutter and Dart, it is possible to create separate modules or mini-apps that can function independently. However, despite this , the module can’t be delivered one at a time. 


  • Supports cross-platform development

  • Easier to fix bugs

  • Fast and efficient programming


  • Mechanisms are not lightweight

  • Dart is not as popular as other languages

4.) React Native

Like Flutter, React Native is a mobile application framework supporting cross-platform development

This is a great option, especially if you want to SAVE MONEY when developing microservices architecture while still having native-level performance.

Developers love how they can reuse the codes and recycle the components they coded and developed in the React Native ecosystem.

Above that, sharing and delivering codebases within the program is possible to ease the workflow.


  • Quick and cheap to develop

  • Cross-platform support

  • Reusable codes and components


  • Slower performance than native

  • Doesn’t have custom modules

5.) React.js

One of the good frameworks that support microservices development is React.js. – an open-source JavaScript library popularly used in developing mobile and web applications.

It’s also relatively simple to use, as it doesn’t require developers to follow strict rules, and it’s EASY to integrate plug-ins or libraries into an existing project or codebase.

By utilizing Virtual DOM, it can also make quick updates and dynamic front-end. It’s also high performing and offers a good user experience.


  • Easy plug-in integrations

  • Quick updates

  • High-performing user experience


  • Only covers UI

  • Poor documentation

6.) Node.js

Microservices Node JS is said to be beneficial for startups and organizations who want to start microservices architecture since it’s based on V8 runtime.

Microservices Node JS is famous among developers because developing apps for web services is simple and easy. Plus, it offers HIGH PERFORMANCE for the program, cheaper development and maintenance costs, and increased productivity.

  • Cost-effective

  • Increase developer’s productivity


  • Not scalable

  • Unstable API

7.) Nest.js

Nest.js is another microservices framework that allows developers to code Node.js. It’s a good microservices framework since it’s a group of small services interacting with each other.

This general-purpose development methodology is highly adaptable, especially for C# and Java developers.

It allows for the utilization of various technologies and tools, enabling programmers to choose the right tool for a specific function or business skill.


  • Easy to adapt

  • Has a library of tools and technology


  • Doesn’t suit complicated API
8.) Laravel

Laravel is commonly used in developing custom applications. It offers various tools to create a reliable platform that’s easy to deploy and maintain.

This is one of the microservices frameworks that is lightweight and fast. It also has STRONG module boundaries, which is essential for large teams.

Additionally, since it’s versatile, programmers can choose whichever language they wish to use in the development.

It also has API support, per RPC or REST architecture model, and works with different data storage technologies and frameworks.


  • Lightweight and fast

  • Strong module boundaries

  • Versatile with any language


  • Costly

  • Limited support

9.) Elasticsearch

Elasticsearch is an open search and analytics engine central to the ELK Stack. It’s greatly known for its SPEED and SCALABILITY. 

Elasticsearch offers several search options and delivers fast search responses using indexes.

It also reduces the probability of data loss in multiple nodes while allowing data management and storage of huge files. 


  • Quick research response

  • Scalable

  • Store huge files

  • Reduce chances of data loss


  • Not as good as MongoDB and Hadoop in data storage
Other Programming Languages and Frameworks for Microservices

This is known for its concurrency and API support for microservice architecture.

This is primarily designed to handle and develop large and complex apps and in creating web services, and it supports increased productivity of machines.

It also allows developers to write robust tests and instantly embed them in the workflow.

Furthermore, Golang provides access to the RPC framework, GoMicro, and Go Kit, which work perfectly with microservice architecture.

.Net Microservices

.Net microservices provide built-in support to build and deploy microservices with Docker. It also comes with APIs that easily consume already developed microservices architecture.

This means that developers no longer need to revamp the application entirely to migrate.

Besides this, it also allows gradual migration to .Net core technology with new and existing microservices architecture since it can be mixed with other apps written in other languages. 

Java Microservices Framework

The Java programming language is known to be a great option due to its annotation syntax.

Java microservices are easy to develop, especially when coupled with microservices frameworks.

Additionally, it offers UI, model components, and connectivity to back-end resources. Java microservices offer service discovery solutions that are also easy to connect to microservices.

It provides several frameworks for this purpose, including Spring Boot (for aspect oriented-programming), Dropwizard, Restlet, and Spark (supports creating web apps).


This is a high-speed, NoSQL database that facilitates elastic data structures and quick replies for solving complex coding challenges. It also supports values in addition to a core data model.

What Is Microservices Architecture?

Microservices architecture is a technique or development process that allows a program to host several applications under a single UI.

It is an extensive concept implemented to disintegrate the application to create fragments of smaller services that can function INDEPENDENTLY while interacting in lightweight mechanisms.

Businesses primarily utilize microservices architecture. As they seek to expand their presence in the industry and gather a larger customer base, they’re also creating complex apps.

Instead of using the traditional monolithic architecture developed under a single code base, larger projects requiring smaller entities migrate to the more advanced structure.

What Are the Benefits of Microservices Architecture?

While monolithic structures are cheaper and easier to launch, microservices architecture still has a bigger edge that would easily overthrow the former.

There are many reasons why you should start writing microservices:

  • Simple to develop – Given that each service is divided into smaller components, it’s easier for developers to input codes and web protocols intended for a specific program.

  • Independent – Each service functions and operates independently. Hence, when one module fails, it doesn’t hurt the entire application.

  • Modifiable – Adding features, interfaces, and other inputs to the program is also relatively easy since each service is grouped according to business skill.

  • Scalable – Developers can straightforwardly scale the program up or down depending on business needs since its architecture is built into individual-versioned parts.

  • Easy to maintain – Given that each service operates independently, it’s also easy for developers to autonomously maintain, test, implement, and deploy one functionality after the other without compromising other model components.

Why Should You Migrate to Microservices Architecture?

Migrating to microservices architecture from the traditional monolith is a HUGE STEP for businesses.

While the latter is cheaper, the former is in the position of catering to complex applications.

Here are several reasons why you should consider migrating to single, independent microservice architecture:

  • Monolithic codes are complicated to handle and maintain. Services also lack distinction since they run as a single code base.

  • Developers are FREE to use a diverse programming language for each service, given that they are not built under one system.

  • It’s simpler to scale up and down and modify inputs in each service with microservices architecture.

  • Given that monolithic codes are built under the same system, modifying one component in the model would COMPROMISE the others. This could also happen when technical failures occur in a component.

Choosing the Best Programming Language for Microservices: What to Look For

If you’ve finally decided to switch to microservices architecture, you must choose the appropriate programming language based on business needs.

Here are the things to look for :

  • Observable and independent deployment process

  • Supports automation and operates in a customer-centric manner

  • Supports continuous integration

  • Has component decentralization

  • Suited for a business domain
