Virtualizing Business Critical Applications – Integrity & Confidentiality

VirtualizationSecurityRecently I discussed Virtualizing Business Critical Applications and security, which includes availability, confidentiality, and integrity. However, that discussion was more about visibility into the environment for security operations. I purposely left off the discussion of gaining integrity and confidentiality of the data housed within those business critical applications.   Security encompasses a great number of technologies, and those that provide integrity and confidentiality often differ from those that provide visibility into an environment which differ from those that provide availability.

Virtualizing Business Critical Applications – Operations Management and Infrastructure Performance Management

PerformanceManagementAs VMware progresses towards virtualizing more and more business-critical and performance-critical applications, the tools and processes by which the virtualized data center needs to be managed need to change. As a first step, it is important to separate workloads into three groups: Tactical (no one cares if they go down for a while), Business-Critical (they must be up all of the time), and Performance-Critical (they not only must be up, but must deliver excellent response time all of the time).

Virtualizing Business Critical Applications – The Performance and Capacity Sizing Problem

PerformanceManagementVMware (and Microsoft) continue to make excellent progress driving the penetration of their data center virtualization offerings. Over half of the servers run by VMware customers are now virtualized. The progress has been so good that now it is time to ask two important questions. Is what is left to virtualize different that what already has been virtualized? And, if what is left is virtualizing business critical applications, will running them on the virtualization platform be any different than what we experience today?

Applications Performance Equals Response Time, not Resource Utilization

When VMware announced vCenter Operations, it combined performance management, capacity management, configuration management with self-learning analytics into one product (right now this is achieved by bundling three VMware products, vC OPS, vC CapacityIQ, and vC Configuration Manger, but integration over time will likely reduce three databases and three consoles into one). VMware now joins the ranks of many vendors who can monitor virtual (and through integration adapters – physical) environments, and who provide performance and capacity management features.

The ROI for Server Virtualization with Business Critical Applications

Server virtualization has been pretty much of a no-brainer for many IT departments as they were able to dramatically reduce the number of physical servers under management. This has been possible since IT has been able to virtualize the applications that IT owns and supports without IT having to consult or sell teams that own business critical applications. The ROI’s from virtualization have been driven largely by the savings associated with server consolidation. However, as these same IT organizations start to virtualized business critical applications different dynamics and assumptions come into play.
