Are Microservices The Right Choice For My Business?

Are Microservices The Right Choice For My Business?

If you’re working in the world of IT and application development, you may be wondering if microservices are right for you. Microservice architecture has surged in popularity in recent years, thanks in part to the rise of containerized architecture with services like Docker and Kubernetes. These technologies have made it easier to develop loosely-coupled microservices.

 

So, in this article, we’ll discuss some of the benefits and challenges of microservice architecture, to help you decide if they’re right for you and your business.

 

Understanding The Benefits Of Microservices

There are many good reasons that microservices are becoming a popular development methodology in modern software companies. Here are just a few of the top reasons.

 

  • Easily scalable and reusable – Microservices can easily be scaled, and are also highly-reusable in different projects when a similar service or application is being built. This adds up to lower overall costs of ownership and lower development costs.

 

  • Improved DevOps effectiveness – Microservices are ideal for a continuous integration/continuous delivery (CI/CD) DevOps approach, because each individual microservices can be easily changed and updated without affecting the entire program.

 

  • Language-agnostic – Each microservice can use the programming language that is best suited to its function, or which your development team is the most familiar with. This increases flexibility and makes it easier to develop an efficient piece of software.

 

Some of the other benefits of microservices include enhanced security, better fault isolation, high-quality code and more.

 

The Challenges Of Microservice Architecture

 Now that we’ve discussed the benefits of microservices, let’s discuss some of the challenges of working with a microservice architecture.

 

  • Microservice monitoring and management – Monitoring dozens – or even hundreds – of microservices is more challenges than managing a single, monolithic application with a single integrated codebase. To use a microservices-based model, you must begin with monitoring and management in mind, and have a plan that will ensure you can monitor each individual microservice properly.

 

  • Testing complexity – Testing a microservice-based application can be more complex than a traditionally-built application, because there are more dependencies and it can be more difficult to understand where a particular fault or error is occurring. This, along with the complexity of the ways that microservices interact with each other, can make testing difficult for those who are not familiar with a microservice-based architecture.

 

  • Data migration challenges – If you are transitioning to a microservice-based architecture, migrating data and managing it properly can be a difficult challenge. You’ll have to split up a monolithic application into multiple microservices, and it can be very hard to determine the proper boundaries and functionality for each microservice.

There are some other challenges related to microservice architecture, such as more difficulty versioning your software, organizational challenges, and the adoption of a DevOps, CI/CD-focused culture at your workplace.

 

 Are Microservices Right For My Company?

 The answer is not as straightforward as you may hope. Moving to a microservice architecture has a number of benefits for your company, but doing so has some major challenges. If you’re willing to accept and overcome these challenges, though, you may find that microservices are a much better option if you are interested in a scalable, fault-resistant, and highly-secure application infrastructure.
