Celebrating 10 Years of PowerShell2006 - 2016• Jeffrey Snover• Kenneth Hansen• Lee Holmes• Narayanan Lakshmanan• Hemant Mahawar• Bruce Payette• Hitesh Raigandhi• Dan Travison• Jim Truher• Krishna Vutukuri
Congratulations to the team members who’ve been there
since the beginning…...and thanks for all
the great work!
Why PowerShell the Stack?Why wouldn’t you? PowerShell ALL the things!
Twitter PollI polled twitter to see how many layers people are managing with PowerShell
We Now Have• More Layers• More complexity• Consumption models
have shiftedSeeking• Management at Scale• DevOps / Lean Ops• More IT as a Service

Let’s Start with the ToolsWhen you’re a hammer every problem is a nail.
More APIs = More PowerShellGrowth of infrastructure extensibility means more opportunities for PowerShell and its users
Infrastructure Tools• PowerShell• VMware PowerCLI• OpenStack PoshShell• Cisco UCS Powertool• HP Scripting Tools for
PowerShell• SolidFire PowerShell Tools• NetApp PowerShell Toolkit• Community
• PowerNSX• EMC {Code}

Core Challenges• Managing Multiple
Modules/Tools• Relationship Mapping• Scale
Multiple Providers• PSSnapin vs Modules• Each Vendor has an installer• $env:PSModulePath
Defaults• $home\Documents\
WindowsPowerShell\Modules; $pshome\Modules.

Example
$scsiID = ((Get-ScsiLun -Datastore $datastore).CanonicalName).Split(".")[1] $result = Get-SFVolume | Where{$_.ScsiNAAdeviceID -eq $scsiID}
$result | ConvertTo-JSON | Set-Content Datastore-Volume.JSON
$global:DSVol = (Get-Content Datastore-Volume.JSON) –join “`n” | ConvertFrom-JSON
$scsiID = ($global:DSVol | Where{$_.DatastoreName –eq ‘DatastoreName’}).scsiID$result = Get-SFVolume | Where{$_.ScsiNAAdeviceID -eq $scsiID}
Why App DNA?
• Quicker Reporting• Shorter Time to Resolution• Faster Implementation• Improve Value Stream• Dynamic Parameter Sets• Faster PowerActions or vRO
calls.
Growth Areas• More DSC Resources
• Cisco UCS PowerTool DSC
• Moving away from PSSnapins
