With 72 days (despite me saying 71) remaining until AWS re:Invent 2019, we take our first look at an AWS service. In this live stream (originally streamed on LinkedIn), we walk through creating your FIRST ever AWS Lambda function.
We look at the basics of setting up a function, how to test a function, and then connect our new function with a trigger from Amazon S3.
What do you want to learn on the road to AWS re:Invent 2019? Let me know in the comments below!

![Is the Software Supply Chain Corrupted? #shorts
Software supply chain is a relatively new term but not a new idea. Most software is built using a lot of other components. These components should be checked to make sure they are what you think they are BEFORE being packaged up and sent out to users.
Not shockingly, thats usually not the case and new research shows yet again why this practice hurts your cybersecurity by letting hackers easily compromise your software.

![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.
