- technology changes, yet still maintain old technologies
- roles changing: DBA vs DBRE.

12 .Become a Learner, not “I need to learn technology X”
“You don’t need a unanimous vote to
win an election; you just need a
majority. It doesn’t matter if you cast a
few votes for a bad behavior or an
unproductive habit. Your goal is simply
to win the majority of the time.”

- It worked, proved the concept of scenarios for hands-on training
- VMs were base OS images to avoid downloading new image each time scenario
changed. Ansible provisioned each VM based on scenario requirements
- real example scenarios: mismatch timezone in primary/replica setup, point-in-time
performance analysis, continuent tungsten setup, migrating to Galera
- ideal: 15-min practice through scenarios daily (or 1-hour weekly) to practice things
you might not experience frequently on your team.
- Two main issues: time to deploy scenarios was 20-30min, making it hard to do at
beginning of day before distractions. Ansible dependencies on various operating
systems caused friction with troubleshooting and upgrades broke things.

Dependencies installed by Vagrant, versions are pinned.
ControlVM doesn’t need to be installed each time. One/done.
Docker enabled Low start up time: 2-3 minutes instead of 20-30minutes
Why didn’t we start with Docker? Time of development, Docker wasn’t a clear
‘need-to-know’ technology for data infrastructure, and there is a learning curve
working with it.
