17. According to Deloitte:
In 2020, only 14% of on-prem solutions
will be converted to the Cloud

18. • Is everything still used?
• Am I paying too much?
• Am I managing it right?

19. Ok, what’s the Plan?
1. Visibility
2. Optimization
3. Ownership
4. Lifecycle management

20. Visibility
• Measure cost
• Per subscription, resource
group and resource
• Alert on cost variations
• Monitor resource usage
• CPU, Memory, DTU, IO

21. Optimization
1. Idle services, storage, databases
2. Empty services
3. Oversized services
4. Abandonned disks
5. Stopped virtual machines
6. Geolocalized and specialized storage
7. Intermittent activity
8. Reserved instances

22. Idle app services and
virtual machines
• Check CPU activity
• < 15% for app services
• < 10% for virtual machines
• Where?
• Overview
• Metrics
• Alerts

25. Idle databases
• Check DTU activity
• < 5% for SQL databases
• Where?
• Overview
• Metrics
• Alerts

26. Idle storage
• Check I/O activity
• Turn on diagnostic logs

27. Empty services
• Check forApp services with no app
• Overview App service plan (0 / 0)

29. Oversized services
• Check CPU activity
• < 40%
• Check memory activity
• < 45% for app services
• Not available for virtual machines
(only if you have agent installed)

30. Abandonned disks
• When aVM is deleted, but not
the disk
• Powershell only
• Check if Disk AttachedTo
property == null

31. Stopped virtual Machines
• When you shut down aVM
• Stopped does cost money
• Deallocating does not cost
money

32. Geolocalized storage
• Create a GRS by default
• GRS is over twice as expensive as LRS
• GRS is rarely ever needed

33. Specialized storage
• Depending on usage:
• Hot
• Cool
• Archive (blob only)
• Use Azure price calculator

34. Intermittent activities
• VM are expensive for small workloads
• Low CPU usage
• Deallocate => loses credits

35. Intermittent activities
• Save from 50% to 70% over AxVMs

Check

36. Reserved instances
• Save
• ~30%, if you commit to 1 year
• ~60%, if you commit to 3 years
• If your subscriptions is not
MSDNDevTest
• Subscription/Region/Type => EX.
Canada East, 4xA1
• Protected against capacity issues

37. Bonus: Combo savings!
• A1 virtual machine: 65.70$/month
• B1MS. 26.38$/month
• B1MS reserved 3 years. 11.67$/month

38. Bonus: Hybrid benefits
• Save up to 20% when you use an On-
Prem license
• BYOL (Bring your own licence)
• Windows Server, SQL Server
• https://azure.microsoft.com/en-
ca/pricing/hybrid-benefit/

39. What to do?
• Downscale
• Delete
• Change service type

41. Governance plan
1. Categorize your assets
2. Specify an owner
3. Determine an expiration date
4. Have a specialised DevOps team
5. Use a third party tool

42. Categorize your assets
• Enforce a naming convention
• https://docs.microsoft.com/en-us/azure/architecture/best-
practices/naming-conventions
• Enforce tags
• Company name
• Department
• Environment

43. Specify a resource owner
• Create an « owner » tag
• owner : email
• Resource group level

44. Determine an expiration date
• Create an « expiration » tag
• Expiration : date
• Resource group level
