WHAT IS VIRTUALIZATION?
  • Virtualization
    • Presents hardware resources as virtual resources, i.e.:
      • Compute (CPU/Memory)
      • Storage (Disk)
      • Network Interfaces (NIC)
    • Allows managed sharing of hardware resources
    • Presents standard hardware to “Guest” operating systems running inside virtual machines (VMs)
    • Frees software from physical hardware dependencies

virtualization challenges
Virtualization Challenges
  • Lack of formalized strategy, planning, testing, and deployment disciplines – Trial and error model (Fix it later)
  • Increasing complexity of the operational production environment – Service delivery interruptions and outages
  • Lack of visibility and oversight by business management – Risk management and compliance issues
  • Lack of formalized roles and responsibilities with new virtualization model – Technicians are in control
  • Immaturity of operations and performance management systems and tools – Up to 18 to 24 months behind the Virtualization vendors’ products
  • Lack of management measurements and metrics – Meaningful qualitative metrics are not available

22

  • Best Practices:
    • Technology should not be the driving factor for Virtualization – Virtualization must fulfill a set of business requirements
    • Develop comprehensive Virtualization Management and Support Strategy and corresponding Plans
      • Isolate critical or sensitive systems
      • Develop using cross-functional teams
    • Manage all VM deployments using Change Management process which inter-relates with many of the processes mentioned above

  • Currently:
    • Most Business Process Models (Architectures) are based upon “static” defined processes and physical relationships between Configuration Items / Assets (e.g., ITIL V3)
    • IT Operations and Performance Management tools automate processes based upon this “static” model
  • Approach for Virtualization:
    • If no Business Process Model is defined and documented today, this could be the catalyst
    • If there is, move the Business Process Model from Physical to Virtual (P2V)
    • Focus the new model around defining and delivering IT Services, including the qualitative measurements and metrics (e.g., ITIL V3)
change management process
Change Management Process
  • Description: Plans, manages, and controls all changes to the production environment
  • Effects of Virtualization:
    • Change Management Process
      • Impact Analysis of Planned and Emergency Changes
      • Change Back-outs
    • In support of related processes
      • Risk and Compliance Management
      • Availability / Capacity Management
      • Release Management
      • Quality Management
      • Service Continuity Management
      • Asset / Configuration Management

  • Approach to refine Change Management for Virtualization
    • Change Manager needs to revise their Change Definition Checklist to include Virtualization
    • Require virtualization representation on the Change Advisory Board and at Post-Implementation Review meetings
  • All Process Owners are responsible for revising their respective processes to support a virtualized environment
      • Thoroughly understand the impacts of Virtualization on their processes
      • Revise roles and responsibilities, business rules, measurements and metrics
      • Develop requirements for new and improved operations and performance management tools
effect of virtualization on organization structure
Effect of Virtualization On Organization Structure
  • Currently:
    • Technical and operational expertise (Probably not in agreement of how to support a Virtualized environment)
    • Management disciplines and governance were developed over time to support a physical environment (Probably not at the level required to support a Virtualized environment)
  • Approach for Virtualization:
    • Establish ownership of the Virtualization Planning and Management process – Must work closely with other Process Owners because VPM has significant impact
    • Establish Virtualization Manager
      • Understands the whole production environment from a technical perspective
      • Is responsible for managing Virtualization strategies and plans and resolving all Virtualization issues (Attends Change Advisory Board meetings)
    • Strong relationship with the strategic Virtualization vendors

Effects of

Virtualization

26

effect of virtualization on measurements and metrics
Effect of Virtualization On Measurements and Metrics
  • Measurements and Metrics - Quantitative (how many?) vs. Qualitative (how well?)
  • Currently:
    • Quantitative measurements are justifying Virtualization investments – Dollars saved on servers, facilities, energy, and staff
    • Validity of current qualitative results could be suspect (e.g., Problems caused by Changes)
  • Approach for Virtualization:
    • Determine impact of Virtualization on IT’s Mission, Goals and Objectives, Critical Success Factors, KPI’s, and current measurements/metrics
    • Revise all processes to deliver redefined quantitative and qualitative measurements (e.g., Service Level Agreements, Business Value, Customer Satisfaction) in support of Virtualization Management and Support Strategy

Effects of

Virtualization

27

effect of virtualization on it management systems
Effect of Virtualization On IT Management Systems
  • Currently:
    • Most operations and performance management systems (e.g., monitoring tools) are mature in support of a physical model in the quantitative sense, but less mature in qualitative sense
    • All current systems and tools are immature in support of virtual model in both quantitative and qualitative sense
    • Major enterprise management tool vendors (HP, CA, IBM) - Trying to catch up with the technology
    • Virtualization vendors (VMware, Citrix, Microsoft) are focused on improving their technology, not building management support tools
  • Approach for Virtualization:
    • Define the new systems requirements during revision of the IT processes
    • Map to management systems and tools of major enterprise management vendors (HP, CA, IBM), to Virtualization vendors (VMware, Citrix, Microsoft), and to in-house systems and tools
    • Apply a “muscle management” style until mature operational and performance systems are available

Effects of

Virtualization

28

addressing the challenges
Addressing the Challenges
  • Lack of formalized strategy, planning, testing, and deployment disciplines
    • Process – Define the Virtualization Planning & Management (VPM) process to support your organization
    • Strategy – As output of VPM process, define the strategy to manage and support a Virtualized environment
  • Increasing complexity of the operational production environment
    • Process – Tightly align VPM process with Change Management, which serves as “gatekeeper” to the production environment
    • Management Systems – Fill the current gaps in operations and performance management tools to support Virtualization – Through defined processes and/or vendor or in-house tools
  • Lack of visibility and oversight by business management
    • Governance – Align the Virtualization Strategy with Enterprise and IT Governance principles
    • Process – Align the VPM process with Enterprise and IT risk management-related processes and report results to Enterprise management

Effects of

Virtualization

29

addressing the challenges1
Addressing the Challenges
  • Lack of formalized roles and responsibilities with new service delivery model
    • Organization Structure – Establish ownership and accountability for Virtualization within senior IT management team
    • Process – Define process roles and responsibilities within the VPM process, including Process Owner and Virtualization (Process) Manager
  • Immaturity of operations and performance management systems and tools
    • Process – Align VPM process with other Service Delivery and Support processes
    • Management Systems - Develop/update process automation requirements and select/implement operations and performance management systems
  • Lack of management measurements and metrics
    • Governance – Take a top-down, Balanced Scorecard or Management Dashboard approach to defining management measurements – Mission, Critical Success Factors, Key Performance Indicators
    • Process / Measurements – Align VPM process with other processes to provide qualitative measurements (Service Level Agreements, Business Value, Customer Satisfaction)

Key Concepts – Final Thoughts
  • Virtualization Planning and Management

Effects of

Virtualization

The world we’ve made is a result of the level of thinking we have done thus far, creating problems we cannot solve at the same level of thinking.Albert Einstein

  • Virtualization requires a significant change to the Service Delivery Business Model – From managing a physical production environment to a virtual or mixed virtual/physical production environment
  • No formalized business management Best Practices or Silver Bullets available from any research or governance entity – Requires solid strategy, thorough planning, and effective process management disciplines to improve the operational maturity of a virtualized environment

“We’re finding that security is the forgotten stepchild in the virtualization buildout.”

- Steven Elliott, IDC

“It’s easy to make a VM. People create lots of VMs. VMs increase complexity and connections geometrically.”

- Erik Worbel, Director of Product Management, VMware Corp.

“Hyper-V will ultimately mean that the power of virtualization will reach the masses and that virtualization is no longer an 'if' but a 'when.'  The 'when' pretty much just became 'now'.”

- Mark Bowker, Enterprise Strategy Group
