Dear Architect,

Welcome back to our weekly issue!

This week we have in our spotlight the ThoughtWorks Technology Radar, a great report done by the most prominent names working in ThoughtWorks. I personally love the radar because provides new ideas to try (or not) in your daily job.

After a while, it's time to talk again about documentation and in this case about post-mortems. I found post-mortems extremely helpful for learning from our mistakes and when done well they are a valuable process for increasing the knowledge of your platforms inside your teams

QCon Plus Virtual Conference will take place this May and for the first 25 sign-ups from this newsletter, you can have $50 discount. I had the chance to attend and speak at QCon and the quality of the talks is really top-notch, if you have a chance to join the event, you won't regret it.

My colleague Marcia Villalba, interviewed Marc Brooker - Senior Principal Engineer at AWS and one of the persons behind the AWS Lambda platforms. If you wanna know what's running under the hood I recommend spending an hour of your time to understand Lambda architecture.

Finally, Spotify shares its journey on revamping the desktop application architecture, providing valuable insights on the reasoning behind certain decisions and the impact they had on the development velocity.

Enjoy the read and see you next week!



Technology Radar

We encourage you to explore these technologies.
The Radar is graphical in nature, grouping items into techniques, tools, platforms and languages & frameworks. When Radar items could appear in multiple quadrants, we chose the one that seemed most appropriate. We further group these items in four rings to reflect our current position on them.

Post-mortems to the rescue

A good post-mortem process is broken down into three major parts, the first of which will usually take up the bulk of your time:

  • Writing a post-mortem.
  • Reviewing the post-mortem and publishing the post-mortem.
  • Tracking the post-mortem.

How Lambda works - cold starts? Firecracker? Container support?

Let's look under the hood of AWS Lambda and learn how Lambda works. Marc Brooker - Senior Principal Engineer at AWS and one of the persons behind the AWS Lambda platforms unveils the magic behind AWS Lambda. He shares with us how the platform changed over time, the challenges, the innovations and so many other things.
Case Study

Building the Future of Our Desktop Apps

Software engineering, as a culture, seems determined to sell each other on solutions based purely on some benefits, without consideration of context, complexity and cost. If you are not using complicated architecture pattern X or infinitely scalable message broker Y you are doing microservices wrong.

Thanks for reading Dear Architects 🙏
