Reliability in the AWS Well-Architected Framework

Fall/2021 – 2 min read

An overview of the AWS Well-Architected Frameworks' Reliability pillar.

Reliability is one of the five pillars of the AWS Well-Architected Framework. The framework describes the principles and techniques required to make informed trade-offs when you’re building in the AWS Cloud.

I’ve taught thousands of builders how to build better using the framework on the A Cloud Guru platform. Be sure to check out my course, “Mastering The Well-Architected Framework”

This 👇 Twitter thread dives deeper into the Reliability pillar of the framework…

. @awscloud defines reliability as, "…the ability of a workload to recover from infrastructure or service disruptions, dynamically…meet demand, and mitigate disruptions." simply: systems shouldn't fail & if they do, recover quickly & automatically 🧵☁️ #cloud #devops

three areas of focus for the Reliability Pillar: - limits == know them, stay within them - networking == topology, bandiwdth, & latency will impact a lot of things - availability == your solution should be ready for business use almost all of the time 🧵☁️ #cloud #devops

. @werner's keynote from @awscloud #reinvent last year centered around the ideas that are core to this pillar. if you haven't already, watch it at https://www.youtube.com/watch?v=jt-gV1YwmnI&feature=youtu.be (even if you have, it's worth a re-watch) 🧵☁️ #cloud #devops

the pillar principles here are: - recover from issues automatically - scale horizontally first for resiliency - redule idle resources - manage change through automation - recover from issues automatically 😉 🧵☁️ #cloud #devops

biggest mistake I see with this pillar is that builders put too much focus on things never failing that would be great but 💩 happens. being able to recover automatically will do a lot more for your customers than trying to make everything 100% available 🧵☁️ #cloud #devops

you can read the entire Reliability Pillar at https://docs.aws.amazon.com/wellarchitected/latest/reliability-pillar/welcome.html remember, the Framework teaches you to balance the concerns of the five pillars to find the right fit for your solution...and that balance will change regularly /🧵☁️ #cloud #devops
