Book Summary: “Building Microservices” By Sam Newman

1 Sentence Summary: Building Microservices allows us the opportunity to tackle software complexity and deliver faster; if (and it’s a big if) we build our services right: choosing the right tech, interfaces and integration patterns.

Building Microservices Book

Microservices are a way of breaking down applications into their parts so that businesses can deliver the components separately, experiment with distinct technology stacks and create clear boundaries between business logic.

But building microservices isn’t easy an easy task. With microservices you need to consider many things, such as: how (and where) you split the services, how they talk to each other (integration) and what data they share.

It’s in-vogue at the moment to debate on the virtues of Microservices vs. Monoliths. But ultimately they’re just two different architectural patterns that solve different use cases. Ideally you should understand both patterns.

Here are my three big takeaways:

  • An architect is a town planner
  • Microservices are data abstractions
  • Independently deploy services

Reader Question: Which AWS Certificates Should You Start With If You’re A Junior?

In reader questions I share real reader questions / answers. In this question we discuss with AWS and where to start with AWS certificates. Also, if you have a question of your own, feel free to submit it.


Hey Lou, I’ve been following you since I registered in

Your posts and blog are some of the reasons I got interested in Cloud, but I kept delaying it because I didn’t want to rush into it, now that I’ve learned Docker, Swarm, Kubernetes, Jenkins, Ansible, Linux administration and a bit of cloud with Digital Ocean droplets (mind you I’m a junior so I have very little experience), I feel ready to begin AWS, I’m so excited you have no idea. I bought a course on AWS Architect Associate, but I haven’t started it yet, I have one question.

I’m aware AWS has four levels: foundational, associate, professional and specialty. I’m also aware associate has three paths: architect, developer, sysops.

I read that it could take a couple years to move from associate to professional, should I put all my time into one path? or should I learn all three associate paths before focusing on one?

Also, if you have any general advice for me and/or any useful posts from your blog before I begin AWS I’d seriously appreciate it.

Thank you very much!
