Perils, pitfalls and problems need solutions. So, I asked Jasmine Noel to continue her discussion and to focus on what an enterprise might do to address the issues. Jasmine -
Tools to Tame Heterogeneous Virtualization Management
As I mentioned in my initial blog, virtualization is elevating the daily stress for over-extended datacenter administrators to alarming levels. Higher business agility and lower capital costs through virtualization can’t be achieved without sophisticated, complete, and always-on management of heterogenous virtual computing resources. In other words, agile management of heterogeneous virtualization is critical for business agility and profitability. Hence, the reason administrator stress levels are going through the roof is that they don’t have agile management of heterogeneous virtualization.
It is vital, and not optional then, that IT organizations become adept at matching increasingly dynamic needs (be they automated workload schedules or on-demand service requests) with the resource flexibility afforded by virtualization’s rapid provisioning strengths. As such, system administrators are quickly realizing that they need to look for a different type of management solution. So what are the characteristics of this new solution type?
A policy-based approach is a key characteristic of this new solution type. Virtualization enables application images to move to different virtual machines very quickly (in some cases before admins get a chance to check their emailed service tickets). Policies enable IT to introduce some necessary controls around those moves and changes. Policies can also simplify the workload to resource matching process. For example, policies can ensure that multiple workloads all run on the same virtual machine in a particular datacenter location, or incorporate time of day requirements so that a workload spans ten virtual machines during the day but thirty virtual machines at night.
Centralized management of dense computing infrastructures (be they Blades, packaged Cloud systems, or mainframes) appears to be a natural extension of this phenomena because for the first time, administrators truly need a centralized management platform to manage virtual systems. Many IT organizations are learning the hard way about the sprawl created when virtual images are deployed at will with minimal oversight or visibility into how the environment is changing. System administrators need management solutions that make oversight and resource visibility as quick and seamless as deploying the virtual images. Solutions which afford centralized control over all virtualization options and extend across a diverse infrastructure enable optimal use of administrators’ time.
Besides centralization, the solution should also have a workflow-based approach to automation embedded in its design. Automating the many other tasks (patching, security checks, compliance checks, etc.) that surround virtual image deployment drive down the business risk of high-speed image deployment. When these tasks are orchestrated as complete workflows, IT productivity skyrockets, which gives administrators the time to focus on policy design and decision-related resource analysis.
There is no escaping these solution requirements. The system management status quo can’t deliver the agile management of heterogeneous virtualization that is essential for business agility and profitability. What administrators can do is demand that management vendors prove how they deliver on these requirements.
