CloudInit: The Good Parts

Linux virtual machines as small as a t3.nano in AWS, as large as a Standard_HB60rs in Azure, and even on-premise OpenStack all share a common service in their boot phase: CloudInit!

Many operators are familiar with supplying a shell script via user-data when provisioning their compute resources, but CloudInit has a massive amount of other functionality that is, more often than not, left untapped.
In this talk, we'll look through some of the features of CloudInit, and how to take advantage of them to improve the operability and resilience of your cloud operations. -
