Dad jokes lead the way in this episode as we interview Chris Martello, manager of application performance at Cengage. Chris is a wearer of many testing hats, but his passion is chaos and breaking things on purpose. Chaos was a natural fit for Chris with his background as a middle school science teacher, so when he made the jump to tech chaos engineering was a natural fit.

Imagine this: you're in the middle of an important presentation when all of a sudden your video feed starts to stutter. You hear other people speaking, but their words are choppy. A message comes through Slack from one of your co-workers: "I think your connection cut out."

As the world becomes more dependent on cloud-native systems, the tolerance for slow services is decreasing. Users expect instantaneous access to services, whether it's for work, entertainment, or even cloud infrastructure. Even small amounts of latency can significantly decrease user satisfaction: nearly half of all users expect web pages to load in under two seconds, and as many as 28% of users will permanently abandon a slow site.

In the field of Chaos Theory, there’s a concept called the Synchronization of Chaos—disparate systems filled with randomness will influence the disorder in other systems when coupled together. From a theoretical perspective, these influences can be surprising. It’s difficult to understand exactly how a butterfly flapping its wings could lead to a devastating tornado. But we often see the influences of seemingly unconnected systems play out in real life.

Being new in tech an be intimidating! Thankfully, folks like Carissa Morrow are shining examples of how to come into tech from the ground up. Carissa began with a career shift and just started coding, went through the Boise Codeworks bootcamp, and made the jump to tech.

When Ticketmaster started their Kubernetes migration, they had to address a huge problem: whenever ticket sales opened for a popular event, as many as 150 million visitors flooded their website, effectively causing distributed denial of service (DDoS) attacks.

It's the middle of the night when your phone goes off. You rub your eyes and unlock the screen to see a SEV 1 alert from your incident management tool.

You jump out of bed and start trying to troubleshoot. You log into your cloud provider and try to provision systems manually, only to find out you can't.
