Data is extremely valuable. We've seen that with data brokers, social media giants, and almost every company out there. The current attitude is to gather all the data possible, save it forever, and monetize it later on.
That's problematic for a number of reasons. It's hard to manage that much data leading companies to simply allow internal access and prevent "outsiders". It also makes a tempting target for hackers.
What to do?
Maybe tidy up a bit? Take some inspiration from Marie Kondo and asked some key questions about the data your collecting.

![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.
