Study: Virtualization Brings New Levels of Complexity to Services

A new study from independent IT management software company CA (News - Alert) finds that the continued expansion of virtualization introduces new levels of complexity that threaten the quality, reliability and security of services.



CA released the findings of the commissioned study conducted by Forrester (News - Alert) Consulting on behalf of CA that examines the impact, challenges, and requirements of operating virtualized IT environments. The study also found that as day-to-day production responsibility shifts from subject matter experts to operational generalists, new management and automation tools are needed to minimize the risks.

Roger Pilc, corporate senior vice president and general manager of Virtualization and Service Automation at CA, said that the study results reflect CA's belief that management is the key to unlocking the business value of virtualization.

“Comprehensive, enterprise-class management and automation can increase IT agility, reduce costs, improve service quality, and reduce risks in physical, virtual and cloud computing environments,” he said.

Key findings from the survey of 257 virtualization decision-makers in the United States, United Kingdom, France, Germany and Japan include:

  • Moving to internal clouds requires changes to processes and automation management.
  • Many organizations see cloud computing as the logical outgrowth of virtualization.
  • Twenty-eight percent of respondents plan to evolve from virtualization to private cloud computing services for some production workload in the next six months. To attain this goal, the common model of IT service development and operations must be replaced.
  • Process discipline, automation and self-service management tools, and organizational changes are inevitable.

Comprehensive domain coverage is critical: High among enterprise users' requirements is the ability for management tools to seamlessly and comprehensively manage components of the overall virtualized service that are adjacent to the virtual server, including physical systems, network, and storage. Virtualization blurs the lines between domain silos, making seamless management critical.

A top-down, application-centric approach is needed: Business requirements revolve around the applications, not the infrastructure. Application analysis is near the top of desired features for virtualization management.
