26. Use-cases
•Developing cloud infrastructure
software
•Large (>= 16GB memory) long-
running VMs
•Folks who like the idea and think
it’s cool 😎

27. Running Your Own Cloud
• Isn’t as hard or as daunting as you might think
• Deploying and running OpenStack is no
longer scary
• Projects like Kolla and OpenStack-Ansible
make it very easy
• Can be a lot of fun
• Will cost you money
