Summary

In episode #78 of Mobycast, we introduced the AWS Well-Architected Framework, an indispensable resource of best practices when running workloads in the cloud. We explained that the framework defines five pillars of excellence, and we dug deep on the first pillar, "Operational Excellence".

If you missed that episode, hit pause now and go listen to that one first. It's ok, we'll wait for you.
Now, in this episode of Mobycast, Jon and Chris continue their three-part series on the AWS Well-Architected Framework and discuss the next two pillars of excellence: "Security" and "Reliability".
