I recently spoke at AWS Michigan about cloud migrations. The talk wasn’t AWS specific but we sure did talk about it a ton. From defining cloud to addressing priorities to preventing cost overruns we covered a lot during the meetup. I was peppered with questions by a lively audience. After speaking on stage at DevOpsDays Atlanta 2018, there was this awkward moment for me when the first question was asked. I wasn’t mentally prepared for questions during the talk but, adjusted quickly....

I went to DevOpsDays Atlanta for the first time this week. I hadn’t been in Atlanta in a very long time. It sure has changed a ton. Originally, I was going to help run the SJ Technologies booth. But, a speaker had to back out at the last minute and I was asked to fill the spot.

This talk will analyze human tendencies, historical data, and provide real-world examples of how to avoid conflict during your DevOps journey....

Abstract I worked for a large company with several hundred cron jobs running on two systems. Managing these jobs was cumbersome. Resource use during peak times brought things to a halt. Imagine what it was like when systems were down! In this talk, we discuss Kubernetes’ killer feature: Cron Jobs. Description Kubernetes, Jobs, and Cron Jobs What is Kubernetes? Kubernetes has the concept of Jobs Kubernetes Cron Jobs are a relatively new thing Use Case Former employer had several hundred cron jobs running on two systems Resource contention during peak times brought the systems to a halt If one cron job didn’t run it was hard to determine what task failed or didn’t run based on user tickets Chaos if the systems were offline for one reason or another Using minikube and Docker running locally…...
