Well-architect your way to better serverless applications

You can become a serverless blackbelt. Enrol in my course Learn you some Lambda best practice for great good! and learn best practices for performance, cost, security, resilience, observability and scalability. By the end of this course, you should be able to make informed decisions on which AWS service to use with Lambda and how to build highly scalable, resilient and cost-efficient serverless applications.

“What are the best practices that I should follow with serverless?”

This is easily the most frequently asked question I receive. And I have spent the last couple of years producing contents that document these best practices as they emerge. But hard as I tried, these are scattered over many articles and video courses. While they’re useful for someone learning about the serverless paradigm. It’s not the best way for one to conduct a thorough review of what they have built and gain confidence that they have “ticked the right boxes”.

Amazon’s Well-Architected Tool fills that gap. It provides a guide set of questions and suggestions to make sure you have considered and (hopefully) answered the most important questions around:

  • Security
  • Reliability
  • Operations
  • Performance
  • Cost

And today, Amazon has added the Serverless Lens to the (free) Well-Architecture Tool. It allows AWS customers and partners to take a self-assessment of their workload and their current approach.

And at the end of it, highlight the areas you need to improve on and offers you an improvement plan that you can follow.

It’s an incredible amount of information to pull together in a cohesive way. And it’s just what many AWS customers (and mine!) have been asking for. If you want to learn more, then go to the Well-Architected Tool to get started, and read Danilo’s announcement blog post here.

It’s good day for serverless users on AWS, and huge congratulations to my friend Heitor Lessa for a job well done!
