12. VM vs Container
Fridge vs Canned Food? Ask the Right Question!
How to Preserve My Food?
What env Does My App Need?

13. The KEY Concept

14. • MS Package Software
• GUI Application
• Requires Windows Server
Example 1 – MSSQL
VM

15. • Simple Scripts
• Python Installed
• PIP Installed
• DOESN’T Require
Specific OS
• CMD python app.py
Example 2 – app.py
app.py

16. Conclusions
Key take-aways

17. if(require OS configurations){
App runs on a VM
} else {
App runs as Container
}
Conclusions

18. • Where does the company stand?
• Dev, Ops, DevOps?
• Testing Environments?
• Containers on VMs?
Typical Things to Think about…
Containers Might Ultimately Replace VMs
