AWS re:Invent is 75 days away and while that seems like a really long time off, it'll be here faster than you think!
Leading up to the show, I'm hoping to share a number of live streams (maybe 2-3 a week) that help you better understand the AWS Cloud and cloud in general.
While I have a number of ideas, I'm looking to you to better understand what you'd like to see. Walkthroughs of various services? Discussions about design patterns? Even tips & tricks?
Anything goes, let me know in the comments below!
Also, check out my "Ultimate Guide" to the show at https://read.acloud.guru/the-ultimate-guide-to-aws-re-invent-2019-ddf65f2a0a42

![Can We Improve How Netflix Handled Failover Using DNS In 2017? (Reaction)
In late 2017, Netflix did an AWS This is My Architecture video. It was one of the first. In the video they explained how they tackled the problem of failing over when disaster struck.
Specifically, they drilled down on a clever use of DNS records to create a very flexible system that allows services to continue in the event of some pretty significant disaster.
Few companies operate at Netflixs scale (even their scale back then) but this technique is broadly applicable for any team that needs to failover in the event of either disaster or even a simple failure.
Now, a few years later, I react to that video and see whats stood the test of time, what could be done simpler given todays technology, and generally critique the design against the AWS Well-Architected Framework in a mini AWS Well-Architected Review.
