Things that take up my time

● Deploying services

● Installing services on new environments

● Dealing with problems with differences

between environments

● Waiting for new VMs

I Need More Time for Coffee Breaks

Automation- repeatable for all environments

Containerize - environmental dependencies

Isolation- run multiple apps on 1 VM

Spin up new environments quickly.
