Just Out! "Beyond Root Cause: A Better Approach to Understanding Complex System Failures" I'm excited to share my latest article, which explains why traditional root cause analysis and the 5 Whys approach fall short in complex systems. I hope you enjoy it! www.resiliumlabs.com/blog/beyond-...

Resilience Bites #9 - LinkedIn Rewind (week 14) is out! I've discussed a few key concepts, including Sherlock Holmes' "Dogs Not Barking", the tension between high standards and adaptability, and why sometimes "turning it off and on again" contains hidden wisdom. adhorn.me/posts/resili...

🚀🚀🚀New blog post! 🚀🚀🚀 I have been thinking a lot about AI meta-operators, which are AI agents that will manage our systems and make operational decisions. In this blog post, I am sharing some thoughts and asking questions. I hope you enjoy it! medium.com/the-cloud-ar... #AI

🚀 New blog post out! 🚀 This post discusses the 70% problem with AI-generated code, Bainbridge's automation ironies, and what chaos engineering can teach us about managing complexity in the age of AI. I hope you enjoy it! Happy weekend! adhorn.medium.com/chaos-engine...

In every system, something works. Rather than asking what's wrong and how to fix it, ask what's working and how to get more of it.

The best time to test your runbook is before the incident, not during it.

That is pretty scary.

Will 2025 finally mark the rise of the Chief Resilience Officer?

Right. The years and billions of dollars spent preparing are why Y2K didn’t “live up to the hype.” They *fixed* it. Before it happened. Which is good. Yes.

New HUGE Launch - AWS FIS now supports networking actions on AWS Fargate!!!! Network latency, Network blackhole, and Network packet loss are ready to be used! Long awaited. I'm super happy to see this one out for the end of 2024! Have fun! aws.amazon.com/about-aws/wh...

My second re:Invent talk is up! In this talk, I dive into the internals of thew new Aurora DSQL, looking at how we achieve each of the ACID properties, and highlight some of the decisions we made as we designed the product. www.youtube.com/watch?v=huGm...

Static stability. Where 'doing nothing' is actually the most productive response.

I have been doing an #amazon-q-advent over the past 12 days, and have daily Amazon Q Developer tips that I will publish until Christmas Day. Today's post - dev.to/aws/amazon-q...

Don’t fear what you know about your systems. Fear what you don’t know!

Can you imagine if people acted like most software libraries? You’d ask them a question, and sometimes, they’d just stand there, waiting for an answer forever. Set explicit timeouts folks.

There are two kinds of developers: those who say there is no such thing as infinite recursion, and those who say "There are two kinds of developers: those who say there is no such thing as infinite recursion, and those who say"...

The fourth and last in my series of blog posts on our new Aurora DSQL database is up! This time, we're looking at what happens during network partitions, and how we preserve consistency, availability, and durability. Check it out: brooker.co.za/blog/2024/12...

During @werner.social keynote at #reinvent, I was secretly hoping he would bring in the crew from that video , taking down a Jeep and putting it back together in under 5 minutes. That is Simplexity at its best. www.youtube.com/watch?v=tnLZ...

Technology is evolving to tackle humanity's hardest problems. From clean energy innovations and disaster preparedness to tools to fight disinformation, success now means making a positive impact. Read my tech predictions for 2025 and beyond: www.allthingsdistributed.com/2024/12/tech...

You want 99.999% availability for every services within your application? Are you sure? Because last I checked, not all services are created equal, folks. Know what really matters most to your users and business.

One of the best part about being part of this organization is working with a team that's constantly innovating. This includes a team of scientists that continue to equip the Q Dev Agent with more capabilities, e.g. new tools to search, navigate, understand, and modify code with precision.

New blog post, with my personal take on our launch of Amazon Aurora DSQL: brooker.co.za/blog/2024/12...

More information from @marcbrooker.bsky.social on the Aurora DSQL announcement brooker.co.za/blog/2024/12...

#reInvent This one is awesome! An active-active distributed architecture, Aurora DSQL ensures strong data consistency designed for 99.99% single-Region and 99.999% multi-Region availability. All that in a #serverless package. aws.amazon.com/fr/rds/auror...

🤩 Amazon Aurora DSQL 😍 Whhoo 🎉🎉🎉 ⬇️ Ca, c'est une des grosses annonces de cette année, pour moi ! 🤔 Et vu pendant combien de temps il a introduit le sujet, c'est en effet un gros truc, et pas que pour moi ^^ Werner parlera plus dans deux jours de "comment ça marche" ;-)

Synchronization is for clocks, not tasks. Embrace jitter.

Good morning Vegas. How are you doing today? #reInvent

now, we can share *any* VPC resource over AWS PrivateLink! *this* is PrivateLink the way we always wanted it! 🤯🤩 aws.amazon.com/about-aws/wh...

And so the journey to #reinvent starts now. See you there!

Stop lying to yourself. Past performance isn’t a predictor of future performance.

In one of my previous companies, we had a fitness competition. The team with more than 10k steps per day would win a cash bonus. Teams were so eager to win that some even put fitness trackers on their dogs to make sure they got 10k steps per day. Talk about getting caught up in surrogate metrics!

Pay attention to what isn't there, not just what is.

The most important lessons aren't taught in books.

Too good not to repost.

#reinvent hack. Set your LinkedIn Profile as a QR code. Make that QR code your phone's background. There, no need to carry business cards. One tap on the phone and you are good to go. You are welcome.

Join me! This one is sure to be a lot of fun, especially if you enjoy a technical deep dive.

To my dear friends in the US. May your Thanksgiving be full of peace, love and joy.

A new-launch session hosted by Marc Brooker has just popped up in the re:Invent session catalog. Seats are still available, and I'm sure you don't want to miss it.

Every time I say yes to talk at #reInvent I underestimate how panic I will get... every.single.time Will I ever learn?

AWS #reInvent2024 is less than a week away. Here are some of the must-see sessions on the topic of #Resilience. 🧵

MTTR is like that friend who always insists you split the dinner bill equally, even though you just had a side salad while they ordered the $50 steak and a bottle of wine.
