This document discusses moving from traditional on-premise data centers to cloud and DevOps models. It emphasizes automating servers, treating configuration as code, continuous integration and deployment, monitoring with metrics, and adopting an agile development approach to release more frequently with higher quality and reliability. The document is presented by Fernando Honig from Rackspace on cloud and new datacenter service models using DevOps.

3. SWITCH FROM THIS..

4. TO THIS..

5. QUESTION:
How many of you are in the
cloud?

6. 3 MYTHS ABOUT CLOUD:
• Is not secure:
– Truth: Public cloud is multi-tenant. You potentially could have noisy neighbors.
– Remediation: On-Premise cloud, Virtual Private Cloud, Hybrid Cloud
• Is too complex:
– Truth: Different types of cloud, with differing levels of complexity.
– Remediation: Choose a cloud provider who can offer you tools and support
• Cloud is for everything:
– Truth: Not all applications are suitable for cloud computing.
– Remediation: There will be situations where security requirements, flexibility,
performance or control will preclude the cloud

7. SCENARIO

8. BE READY..

9. Let’s focus on..
• Server Automation
• Configuration Management
• Everything as a Code
• Code Repositories
• Testing Overview
• M-T-V
• Money
• Time
• Value
CLOUD + DEVOPS
NEW DATACENTER SERVICE MODEL

10. AUTOMATE YOUR SERVERS
Everything IS code!
Treat your Servers as Commodities
No Server should be “special”
• Should be no “droideka”, “skywalker”, “backup01” names
You might be able to remove a server with zero
consequences

11. QUESTION:
How many of you use configuration
management tools?

12. AUTOMATE YOUR SERVERS
Configuration Management
Creates exactly what you need
Conforms a Server to a Role
Maintains State

14. QUESTION:
How many of you use continuous
integration tools?

15. EVERYTHING AS A CODE
Code repositories
Create the same Development lifecycle
Your Server code is also an application!

16. M-T-V
M-Money
No need to buy expensive tools
No “deployment nights/weekends” anymore
Less outage
T-Time
Speed up your deployment cycle
V-Value
Code Tested
Common goal across organizations

18. DevOps!
• Culture and Work methodology
• Set of tools
• Config Management
• Code Management
• Testing
• Monitoring
CLOUD + DEVOPS
NEW DATACENTER SERVICE MODEL

19. DEVOPS!

20. QUESTION:
How many of you know
what is Kanban?

21. DEVOPS!
Be Agile
Agile methodologies help you get there early
Release early, release often
Release several times a day
Code + CI/CD ensures quality

22. DEVOPS!
Tools
Collectd, Statsd,
Graphite

23. DEVOPS!
CODE MANAGEMENT
AUTOMATED WORKFLOWS
Collectd, Statsd,
Graphite
MONITORING
CONFIG MANAGEMENT

24. AT RACKSPACE
CONFIG MGMT CODE MGMT WORKFLOW MONITORING
Collectd, Statsd

25. CI/CD
• What is CI? What is CD?

26. THE ETERNAL PROBLEM OF IT
How do I go
faster?

27. TRADITIONAL RELEASE APPROACH
COMPETITION IS UNRELENTING
2
EXPECTATION
TIME
AREAS WHERE COMPETITORS
MAY BE AHEAD

28. COMPETITION IS UNRELENTING
2
EXPECTATION
TIME
AUTOMATED TEST & DEPLOYMENT (CI/CD)

29. CONTINUOUS INTEGRATION
If you write it TEST it!
Continuous Integration gives you assurance
Set on good behaviors

30. SERIOUSLY.. TEST IT!

32. CONTINUOUS INTEGRATION
• Also known as CI
• Perform all tests automatically for every piece
of code
• EVERY SINGLE ONE

33. CONTINUOUS INTEGRATION

34. CONTINUOUS DEPLOYMENT
• Also known as CD
• It’s an optional extension to CI
• Once a piece of code has been through CI
releases it automatically
• Very useful for bugs and minor changes

35. CONTINUOUS DEPLOYMENT
Releases
per day 30+ 100+ 20+ 2+
Features
Released Thursday Tuesday Daily Monthly

36. HAVE YOU THOUGHT?
How much does an outage cost
in your company?

37. HOW DO YOU EAT AN ELEPHANT?

38. HOW TO WIN?
Automate Everything!

39. HOW TO WIN?
Plan to fail!

40. HOW TO WIN?
DevOps teams spend more time
improving things and
less time fixing things

41. HOW TO WIN?
DevOps teams recover
from failures
FASTER!

42. HOW TO WIN?
DevOps teams release apps
more than twice as fast

44. Metrics
If it moves Graph It
Graphs and logs are key for your success
The 5% top and bottom tells where to go
