Today’s IT Administrative Challenges

Increasing demands for ITReliance on technology for critical operationsAlways available, from anywhere

Increasing complexityAdding capabilities adds management burdenMost IT cost goes to managing existing systems

Trends of the future magnify challengesMove to data centers – large scale, virtualization, remote managementOutsourcing – lower skilled, high turnover users

The Importance of Windows PowerShell

Designed to reduce the cost and effort required to manage your IT infrastructure Helps to maximize your IT investmentLowers the barrier to entry Reduces time-to-resultsDesigned to help standardize and automate all of your management processes

What Is Windows PowerShell?Revolutionary interactive shell and scripting languageIncluded in Windows Server® 2008 R2 and Windows® 7Drastically reduces the time-to-results with consistent vocabulary and syntaxEasily discovered

No need to find, install, or learn other tools, utilities, or commands

Flexible outputOutput from one cmdlet easily consumed by another

Easily composed Create higher level tools for complex operations

Utilizes the .NET Framework Provides a common management automation platform

Time-to-results drastically reducedConsistent vocabulary and syntax

Verbs: (e.g. Add, New, Get, Set, Remove, Clear)Nouns: (e.g. Connection, EventLog, Member, Printer, Service, Transaction, and WmiObject)

ComposabilityInteractive environments lend themselves to piecemeal (step-by-step / progressive) solutionsEasily composed (pipelined) to solve complex end-to-end management problems

Flexible outputWindows PowerShell outputs objects that can be easily formatted and easily consumed by other cmdlets (no more parsing!)

Windows PowerShell Strengths

ExtensibilityWindows PowerShell takes this to another level with modules

ReusabilityNo more writing point solutions that you stick in a bin folder rarely to be used again

Scripting is no longer an exercise in workaroundsWe finally have purpose-built tools in the box

Able to control executions with transactionsEnd-to-end manageability across server roles

Active Directory®, Exchange, Group Policy, etc.

Windows PowerShell Strengths

Commands comprised of verb-noun pairsPS C:\> Get-ADUser

TAB-completion eases discoverabilityPS C:\> New-AD<now press TAB>

Arguments are positional PS C:\> Get-ADUser –Identity JamesPS C:\> Get-ADUser James

Help is built-in … and that’s consistent tooWell-known, legacy commands supported through aliasing and support for traditional binaries

e.g. dir, cls, cd, md , ping.exe, fsutil.exe

Where’s my AUTOEXEC.BAT?PS C:\> notepad $profile
