New Forrester Report Offers Insights to Deploying Virtual Network Services

July 2, 2012 at 12:03 pm PST

An interesting new report has been issued by Forrester Research that provides a great deal of market research and insight into the challenges of the data center network supporting large-scale virtualization. The report provides a representative view about the types of obstacles organizations are facing and where they are making new investments, along with some recommended best practices. As usual, the application services infrastructure is one of the biggest challenges, i.e., how to replicate the layer 4-7 and security services that mission-critical applications require in a highly virtualized or hybrid cloud environment. While servers and networks have largely been virtualized, relying on physical firewalls or application controllers can undermine or limit the beneficial effects of virtualization.

Forrester starts by pointing out what benefits customers are looking for and where they see the greatest growth in virtualization going forward. Over the next four years, Forrester sees 500% growth in total virtual x86 workloads that will be hosted in private cloud IaaS (Infrastructure as a Service), where virtual servers are isolated between tenants, compared to 170% growth in private cloud pools in organizations’ own data centers. Forrester points out that overlooking virtual services can “negate private and public cloud investments”, however. 33% of their respondents indicated that they have difficulty integrating public services with internal virtual infrastructures, with 24% specifically citing “frustration with capability, agility and flexibility of traditional application delivery controllers (ADC)”. (see next table).
