New Management Challenges

� Virtualization & SOA break old management models

– Need to manage virtual and physical relationships

– IT relies on tribal knowledge for infrastructure dependencies

� Discovery & configuration management pain

– 78% of outages caused by self-inflicted misconfigurations

– Stand alone best of breed tools no longer sufficient

� Change & compliance management pressures and costs

– Change management accounts for >60% of data center costs

– Only 1 in 10 companies can effectively measure compliance

� IT service desk and IT infrastructure management disconnect

– Operationalizing ITSM & ITIL difficult: people, process & technology

– Closing the loop from service desk through IT operations


Virtualization and SOA

� A combination of the movement towards a service oriented architecture and a virtualized approach to sharing resources is required

� Service Orientation provides a standardized approach to modular business services and interfaces

� Virtualization provides a variety of approaches to more efficiently and effectively share these resources

- Hurwitz & Associates, April 2008


Virtualization as the next stage of SOA

� SOA and virtualization are intended to provide– better resource utilization

– optimize corporate computing assets

� Both require sophisticated management of resources

� The combination of SOA and Virtualization help the IT organization meet the business’s anticipated service level

Hurwitz & Associates, April 2008


Wikipedia - Application Virtualization Defined

“Application virtualization is an umbrella term that describes technologies that improve application compatibility and manageability by encapsulating

applications from the underlying operating system on which they are executed. A virtualized application is not installed inthe traditional sense, although it is still executed as if it is.

Application virtualization differs from operating system virtualization in that in the latter case, the whole operating system is virtualized rather than only specific applications. “


Virtualization Client Computing Taxonomy

� Application Virtualization Software– Encapsulates and isolates application from underlying host OS and other applications

– Citrix Presentation Server, Altirus Software Virtualization Suite, Thininstall, Microsoft Softgrid

� Desktop Virtualization Software– Uses VMs to decouple client from host hardware and software including OS, App and Data

– Server hosted or Client hosted

– VMware VDI, Virtual Iron VDI, Citrix XenDesktop

� Virtual User Session Software– Runs on server with multipe user sessions with

– TSO, Mainframe, ugly green screens!

– Citrix Presentation Server, MS Terminal Services

- Mike Rose, IDC, December 2007


Virtualization: Client Mgmt Paradigm Shift

9

“In a growing number of organizations, traditional PC software distribution approaches are no

longer sufficient to address all user requirements.

A combination of streaming and operating-

system- (OS-) to-application virtualization often

can fill those deficiencies, improve the user's

experience, and may improve the efficiency of

application packaging and testing for IT.”

- Ronnie Colville, VP Gartner, October 2007

Works like a Native App with Mgmt Tools:

�Existing infrastructure �Leverage key features

�Policy Orchestration�Check point restart�Software Usage & Inventory�Rollback & More…� Connection to Asset Mgmt & CMDB� Reporting & Analytics

– Lower Support Costs

– Reduced Backoffice costs

� Improves Flexibility– Run any application on any hardware

� Simplifies Management– Rapidly deploy systems from templates

– Simplified desktop updating

– Consistent desktop deployment

� Ensures Security– Leverages perimeter and host security

– No distributed data risk

…And a Need to Simplify Core IT Processes

� Too many changes to manage:– more changes occur more quickly than ever before

� 1:1 application per server becomes many:1

� Too many configurations to track: – more relationships exist between the things that are changing

� 1:1 element per server becomes many:1

� As a result: – Increased task complexity, potential errors and time

� a 10 step change process and one expert becomes many steps and multiple experts

…Through Process Automation

Drivers for process automation:

� Configuration Management

� Compliance

� Problem Management

� Change Management

… Dramatically Improving IT Service Delivery

in the Virtualized Data Center


The Heart of the ProblemEmpowering IT operations to manage the Virtualized Data Center requires a clear

understanding of virtual and physical relationships to fully leverage the power of

virtualization and maintain service delivery commitments.

Efficiency ImprovementsTo manage the Virtualized Data Center, IT operations must unify discovery,

compliance, problem, and change management processes across the virtual and

physical domains.

World Class SolutionsIT must discover and model the virtualized data center. By automatically collecting

and analyzing infrastructure details IT can simplify the planning and management of

virtualized environments and ensure compliance.

Industry and Market TrendsAnalysts such as the Gartner Group believe that dependency-driven configuration

management is an imperative for IT organizations moving toward a virtualized

infrastructure and that they “should start planning now to enrich their configuration

management capability. Knowing "what is running where takes on a new importance."

Change Management Example

� Change tracking– Determine & set “gold standard” baselines, detect deviations & violations

– Track configuration changes for apps, services, hardware

� Imperative for incident management & problem management– Alert to RCA tools when a change occurs

– Incident triage: what changed and what should be changed back?

– Problem forensics: post-mortem analysis to determine root cause

� Track changes at parameter-level

� Old & new values , time of change


� Measure demand for applications, servers, and connections

� Identify peak and off-peak periods

� Identify isolated servers

Collect and Analyze Infrastructure Details


Key Challenges Managing the Virtualized Data Center

Accelerates MTTR by relating component behavior to

business impact

Identify the root cause across a virtualized

infrastructure – is it the VM,the ESX, the network, or the

host?

Pinpoint the exact source and impact of a problem in a

complex virtual configuration

Ease of resource pooling

simplifies accounting forshared storage in adynamic environment

Reclaim over-allocated storage no longer being used by dormant

VMs?

Eliminate manual storage provisioning for

virtualized production systems

Ease of provisioning

Define rules across our virtualized infrastructure, clusters and groups are running specific applications versions and ensure security

mandates

Know where your apps were running as VMs move from server to server and what they depend on?

Know how many VMs you really have, where they are, and who’s

using them?

Imagine if you could…

Define compliance and governance policy for PCI and

best practices

Enforce compliance and governance policies for

your virtualized environment

Ease of compliance and governance

Maps Virtual-to-Physical (V-to-P) dependencies

Predict the effect of a change to your virtual network infrastructure prior to

implementation

Ease of motion (e.g., vMotion)

Manages VM sprawl by tracking configuration details

Resolve a complex VM configuration problem before it creates a customer impact
