5 ways to get control of virtualization sprawl

Guest post by Andy MacKay, Sr. Product Marketing Manager – HP Software

 

Advances in server technology have made it almost comically easy to deploy a new Virtual Machine—you can get one up and running with just one click.

 

But what happens then? Whether a VM is running for days, weeks, months or even years, it needs to be maintained. And when it’s no longer required, it should be properly decommissioned.

 

Virtualization sprawl is a growing challenge for most IT organizations, as more VMs are deployed every day—but the teams that are managing this infrastructure are not scaling to the same degree, if they are scaling at all.

 

Automating VM lifecycles and compliance

Clearly, automation has become a necessity. But how do you ensure you have complete visibility and control over a rapidly expanding virtual machine environment?

 

Here are five features to look for in a server management tool that will ensure you can manage the complete lifecycle and compliance of your VMs:

 

  1. Create VM templates from “golden” servers — VM templates should contain everything you need to quickly and repeatedly create standard, fully compliant and fully manageable VMs. This includes: operating system, patches and patch policies, software and software policies along with audit policies.HP-SA lifecycle mgmt.png



 

2. Proactive update policy-based enforcement on VMs as well as VM templates — Ensure your servers do not drift out of compliance by updating your policies to the latest software, configurations, patches, and audit rules. Then you will need to remediate your servers to keep them up to date with the new policies.

Full end-to-end lifecycle and policy management for VMs and VM templates — By setting up a well-defined process of deploying, managing, and deleting VMs and VM templates, you can control VM sprawl and compliance drift. For example, if you already have a VM template, attach ongoing patch policies to it so that any VMs created from this template automatically derive the policies that were set on the templates.


 

 

4. Genealogy of VMs — Your server management system should record how each VM was created and display this information. It should also allow you to perform searches on how VMs were created.

5.Search VMs by virtual characteristics — Locate VMs, VM templates, hypervisors, clusters, resource pools and data centers by cluster properties, resource pool properties, number of processors, datastore, hypervisor, memory creation method, power state and many other criteria.
