UPDATE: I’ve started the Serverless Reference Architectures Project that provides additional context and interactive architectures for some of theses patterns along with code examples to deploy them to AWS. Check it out.
I’m a huge fan of building microservices with serverless systems. Serverless gives us the power to focus on just the code and our data without worrying about the maintenance and configuration of the underlying compute resources. Cloud providers (like AWS), also give us a huge number of managed services that we can stitch together to create incredibly powerful, and massively scalable serverless microservices.
I’ve read a lot of posts that mention serverless microservices, but they often don’t go into much detail. I feel like that can leave people confused and make it harder for them to implement their own solutions. Since I work with serverless microservices all the time, I figured I’d compile a list of design patterns and how to implement them in AWS. I came up with 19 of them, though I’m sure there are plenty more.
In this post we’ll look at all 19 in detail so that you can use them as templates to start designing your own serverless microservices.
