In this blog post, I want to look back a little bit because, as Rachel Carson said:
“To understand the living present and the promise of the future, it is necessary to remember the past.” — Rachel Carson
For those who don’t know, Rachel Louise Carson (May 27, 1907 — April 14, 1964) was an American marine biologist, author, and conservationist whose book Silent Spring and other writings are credited with advancing the global environmental movement.
I love this quote and the work Rachel has done for our world — and today, I want to apply her wisdom to chaos…
reInvent 2020 is coming to an end. A lot of new launches have happened since I published Part 1 of this series. Because digesting all the different updates takes time and a lot of coffee, I thought I’d help you out a little.
Following is a curated list of things that I found most important; matters related to architecture, scalability, reliability, performance, resiliency, devops, and security — anything that caught my eye, and I hope will satisfy yours.
AWS Fault Injection Simulator is a fully managed chaos engineering service that makes it easier for teams to discover an application’s weaknesses…
While reInvent just started, the first keynote from Andy Jassy has had a lot of new launches. I know that digesting all the updates takes time and a lot of coffee, so let me help you.

This is hands-down my favorite launch!
Amazon S3 now delivers strong read-after-write consistency automatically for all applications for any storage request, without changes to performance or availability, without sacrificing…
A list of my operational excellence related blog posts.
It takes three interconnecting elements to operate the technology we build successfully. First, you need to have the right culture. Second, you need great tools. And third, you need complete processes.
Part 1 of the series covers the cultural side of Operational Excellence (OE) and examined Amazon’s culture in the context of its Leadership Principles (LPs). Part 2 discusses the role that tools play in achieving OE. Part 3 covers the final aspect to operational excellence — processes — or what we call mechanisms.
Large-scale distributed software systems are composed of several individual sub-systems-such as CDNs, load balancers, and databases-and their interactions. These interactions sometimes have unpredictable outcomes caused by unforeseen turbulent events (for example, a network failure). These events can lead to system-wide failures.
Chaos engineering is the discipline of experimenting on a distributed system to build confidence in the system’s capability to withstand turbulent events. Chaos engineering requires adopting practices to identify interactions in distributed systems and related failures proactively, and also needs implementing and validating countermeasures. The key to chaos engineering is injecting failure in a controlled manner.
First of all, I would like to thank everyone in the AWS Community in Australia and New Zealand and the AWS Heroes who have helped put this event together.
A little reminder that if you plan to share your day with others on social media, please use the hashtag:
A few years ago, I did a talk called ten lessons from ten years on AWS.
That was at the Community…
I’d like to express my gratitude to my colleague and friend Arni Birgisson for his valuable feedback.
Since I published my blog series Towards Operational Excellence, I received a relatively large amount of feedback. But one question, in particular, stood out.
“Can you share an incident postmortem template?”
In this blog post, I will share an example incident postmortem template, which I hope will help you get started. I will also share some DOs and DON’Ts that I have seen work across a wide variety of customers — both internally in Amazon, and externally.
A postmortem is a process where…
