Back in my day…
• Smaller server:admin ratios
• More manual processes
• Limited scripting/automation tools
• Minimal automation targets
• Fewer Layers

Today’s Talking points
• Infrastructure Extensibility
• Policy based management
• The Software Defined Datacenter
• New Tools/Methods
• Will we stop scripting?
• Tomorrow’s Skills

9.
Infrastructure Extensibility

10.
Infrastructure Extensibility
• APIs and SDKs to manage
• Integration with common tools
• Agility to change programmatically
• Maximum feature availability

11.
Policy Based Management

12.
Policy Based Management
• Policies define identity and behavior

13.
Policy Based Management
• Policies define identity and behavior
• Policies can be one to many

14.
Policy Based Management
• Policies define identity and behavior
• Policies can be one to many
• Consistent and flexible
• Control and monitor configuration drift

• Software component developed by
Storage Array Vendors
• ESX and vCenter Server connect to
VASA Provider
• Provides Storage awareness
services
• Single VASA Provider can manage
multiple arrays
• Supports VASA APIs exported by
ESX
• VASA Provider can be implemented
within the array’s management

Storage Policy Based Management (SPBM)
Storage Capabilities via VASA
Pros
• Leverages storage capabilities provided
by VASA provider.
• Fully dynamic.
• vCenter can query Volume/LUN to
validate compliance.
Cons
• Can NOT be used to directly compare
platforms.
• Limited to what storage vendor
presents through VASA.

21.
Storage Policy Based Management (SPBM)
vSphere Tags
Pros
• Widest range of definitions.
• Define custom rules.
• Can assign policies to any datastore that
contains required tags.
• Could conceivably be used to compare
platforms.
Cons
• Not a dynamic process.
• Requires manual work or automation
through PowerShell or vRO.
• Administrators must maintain policies
and tags.

22.
vRealize Automation

23.
Desired State Tools
• Create identity for application, server, or
infrastructure.
• Configuration drift management
• 1:1 and 1:Many deployments
DSC

24.
Software Defined
• IT as a Service - SLAs
• Requires infrastructure
extensibility
• Leverages policies
• Adapts based on active
conditions

25.
For Example…
• Virus identified
• VM tagged as high risk
• VM Network policy changes
to protect
• Once sanitized it can return
to normal policy
• Or you can kill it and create
a new VM

26.
New Tools and Methods
• DevOps Culture
• Disposable app instances
• Containers
• Cloudy stuff
• Version Control
New Challenges to automate!!

27.
Version Control

28.
Version Control
• GitHub (Git)
• BitBucket
• CodePlex
• Subversion
• FlowGrab (vRO)
DO IT!!

29.
Keep on Scripting
• Increased extensibility = more scripting
• Bridge to Software Defined
• Gather info not presented in tools
• Ad-Hoc FTW!

30.
Next Generation Skills
• Must understand all the application needs
• Work to enable self-service
• DevOps is not tools, it’s culture
• Rise of the Infrastructure Developer
