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

Multiple Providers• PSSnapin vs Modules• Each Vendor has an installer• $env:PSModulePath

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
