Best Practices For Building Serverless Microservices

By Robert Mutua

Microservices are a type of software architecture that enables developers to build applications as a set of independently deployable, modular services. These services communicate with each other using well-defined APIs, and are typically deployed on a cloud platform like Amazon Web Services (AWS).

There are many benefits to using a microservices approach, including reduced complexity, improved resilience, and better scalability. When done properly, microservices can help you build applications that are easier to maintain and extend.

What are the Best Practices for Building Serverless MicroServices?

If you're considering building serverless microservices, here are a few best practices to keep in mind:

  1. Keep your functions small and focused. One of the benefits of serverless microservices is that they're easy to break down into small, independent functions. So, when designing your microservices, make sure each one has a single purpose and is as small as possible. This will make them easier to develop, deploy, and manage.

  2. Make use of managed services where possible. When building serverless microservices, you'll likely be working with a lot of different cloud services. To simplify things, make use of managed services wherever possible. This way, you don't have to worry about provisioning and maintaining infrastructure yourself.

  3. Automate everything you can. Another benefit of serverless microservices is that they're highly scalable. To take advantage of this, automate as much as you can. This includes things like deployments, monitoring, and logging. Automation will save you time and help ensure your microservices are always running optimally.

  4. Keep an eye on costs. Although serverless microservices can be cost-effective, costs can quickly spiral out of control if you're not careful. So, make sure you keep an eye on your usage and costs. Set up alerts so you're notified if your costs start to increase. And, consider using a cost-optimization tool to help reduce your cloud bill.

  5. Monitor and alert on errors. When working with distributed systems like serverless microservices, things can go wrong. So, it's important to have monitoring and alerts in place to detect and respond to errors quickly. This way, you can avoid major issues and keep your microservices running smoothly.


By following the best practices outlined in this article, you can avoid many challenges and build serverless microservices that are reliable, scalable, and cost-effective.
