QUESTION:
How many of you are in the cloud?
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
SCENARIO
BE READY..
Let’s focus on..• Server Automation
• Configuration Management
• Everything as a Code
• Code Repositories
• Testing Overview
• M-T-V
• Money

CLOUD + DEVOPSNEW DATACENTER SERVICE MODEL
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
QUESTION:
How many of you use configuration management tools?
AUTOMATE YOUR SERVERS
Configuration ManagementCreates exactly what you needConforms a Server to a RoleMaintains State
QUESTION:
How many of you use continuous integration tools?
EVERYTHING AS A CODE
Code repositoriesCreate the same Development lifecycleYour Server code is also an application!

CONTINUOUS INTEGRATION
If you write it TEST it!Continuous Integration gives you assuranceSet on good behaviors
SERIOUSLY.. TEST IT!
IT WORKED FINE IN TEST
CONTINUOUS INTEGRATION
• Also known as CI
• Perform all tests automatically for every piece
of code
• EVERY SINGLE ONE
CONTINUOUS INTEGRATION
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
