Virtualization

What is virtualization management?

Virtualization management is software that interfaces with virtual environments and the underlying physical hardware to simplify resource administration, enhance data analyses, and streamline operations. It's largely interchangeable across hardware manufacturers and software vendors—allowing enterprises to deploy the management solution that best suits their needs.


Do I really need virtualization management software?

Not always, but it can make your life exponentially easier based on how big and diverse your environments are, how experienced your IT team is, and what your strategic goals are. Someone can manually manage a handful of virtual machines (VMs) fired up on a single workstation, but large enterprises must deploy virtualization management software if they want their investment to be successful. VMs aren't just provisioned automatically when hypervisors are installed—someone needs to tell the software what to do. That usually includes a combination of 4 responsibilities, which multiply each time a new virtual instance is requested.

Provisioning

Provisioning VMs involves processing resource requests, creating templates, and configuring VMs to the requestor's specifications.

Compliance

Making sure virtual environments are compliant involves securing and monitoring systems, identifying issues, and validating user access.

Operations

From lifecycle to capacity management and resource optimization to root-cause analysis, keeping virtual environments operational requires retiring or reclaiming unused or underused physical resources, investigating bugs, and projecting future needs.

Hybrid unification

Perhaps the most complicated administrative task, unifying hybrid environments involves implementing the other 3 responsibilities across virtual, private cloud, public cloud, and container environments.

Virtualization management and automation software reduces the manual effort needed to maintain virtual environments. It can automate approval, provisioning, and configuration workflows; track resource use; and execute policies. Some products even unify management across hybrid environments—so admins can oversee multiple systems using a single set of tools.


Managing traditional virtual environments

Traditional virtual environments are pretty straightforward—they contain physical hardware and VMs. But even these can get unwieldy if there are too many instances.

Imagine working at a large hotel, where you’re not only responsible for solving major maintenance issues but also have to make sure the lights are off, doors are locked, and water isn’t left running in each room. These are simple tasks that can become really, really time consuming.

It's a situation that leaves you with 2 choices:

  1. Check the empty rooms, leaving you little time to solve larger problems
  2. Solve the larger problems, leaving you little time to check empty rooms

What if outlets, faucets, and locks were synced to an app that automatically turned the lights off, locked the doors, and checked pipe flow in empty rooms after guests checked out? It would save you from climbing every step, traversing every long hallway, and opening every door just to perform a few simple tasks—freeing you to solve major maintenance issues that can’t be automated.

In this analogy, every room is a VM. When simple maintenance tasks are spread across hundreds of instances, it becomes unwieldy. Management software can take some of that burden off IT professionals’ shoulders so they can solve big, enterprise-wide problems.

Managing hybrid environments

Hybrid environments consist of 2 or more interconnected virtual, containers, private cloud, or public cloud environments.

These setups are far more complex than traditional virtual environments, since each responsibility is repeated in its own unique way. Imagine all the parts of a typical entertainment system: TV, cable box, sound system, and a few gaming consoles—each with its own remote. But nobody’s ever said that handling multiple remotes is an ideal situation. Rather, it’s something we just tolerate until we spend the time and money on an app that manages the entire system from 1 interface.

The same goes for hybrid environments: Private clouds are secured differently than public clouds, and commissioning VMs is different than commissioning containers. Pair that with your unique business situation, IT stack, and experience level, and you have a lot to consider when it comes to choosing the right management tools. But the right tools do exist, and the best of them unify heterogeneous environments in a vendor-neutral and scalable solution—giving IT admins greater efficiency without increasing operational expenses.
