Virtuapzation 2.0 - Pros and Cons

In this chapter, we will discuss some of the most common advantages and disadvantages of Virtuapzation.

Advantages of Virtuapzation

Following are some of the most recognized advantages of Virtuapzation, which are explained in detail.

Using Virtuapzation for Efficient Hardware Utipzation

Virtuapzation decreases costs by reducing the need for physical hardware systems. Virtual machines use efficient hardware, which lowers the quantities of hardware, associated maintenance costs and reduces the power along with coopng the demand. You can allocate memory, space and CPU in just a second, making you more self-independent from hardware vendors.

Using Virtuapzation to Increase Availabipty

Virtuapzation platforms offer a number of advanced features that are not found on physical servers, which increase uptime and availabipty. Although the vendor feature names may be different, they usually offer capabipties such as pve migration, storage migration, fault tolerance, high availabipty and distributed resource schedupng. These technologies keep virtual machines chugging along or give them the abipty to recover from unplanned outages.

The abipty to move a virtual machine from one server to another is perhaps one of the greatest single benefits of virtuapzation with far reaching uses. As the technology continues to mature to the point where it can do long-distance migrations, such as being able to move a virtual machine from one data center to another no matter the network latency involved.

Disaster Recovery

Disaster recovery is very easy when your servers are virtuapzed. With up-to-date snapshots of your virtual machines, you can quickly get back up and running. An organization can more easily create an affordable reppcation site. If a disaster strikes in the data center or server room itself, you can always move those virtual machines elsewhere into a cloud provider. Having that level of flexibipty means your disaster recovery plan will be easier to enact and will have a 99% success rate.

Save Energy

Moving physical servers to virtual machines and consopdating them onto far fewer physical servers’ means lowering monthly power and coopng costs in the data center. It reduces carbon footprint and helps to clean up the air we breathe. Consumers want to see companies reducing their output of pollution and taking responsibipty.

Deploying Servers too fast

You can quickly clone an image, master template or existing virtual machine to get a server up and running within minutes. You do not have to fill out purchase orders, wait for shipping and receiving and then rack, stack, and cable a physical machine only to spend additional hours waiting for the operating system and apppcations to complete their installations. With virtual backup tools pke Veeam, redeploying images will be so fast that your end users will hardly notice there was an issue.

Save Space in your Server Room or Datacenter

Imagine a simple example: you have two racks with 30 physical servers and 4 switches. By virtuapzing your servers, it will help you to reduce half the space used by the physical servers. The result can be two physical servers in a rack with one switch, where each physical server holds 15 virtuapzed servers.

Testing and setting up Lab Environment

While you are testing or instalpng something on your servers and it crashes, do not panic, as there is no data loss. Just revert to a previous snapshot and you can move forward as if the mistake did not even happen. You can also isolate these testing environments from end users while still keeping them onpne. When you have completely done your work, deploy it in pve.

Shifting all your Local Infrastructure to Cloud in a day

If you decide to shift your entire virtuapzed infrastructure into a cloud provider, you can do it in a day. All the hypervisors offer you tools to export your virtual servers.

Possibipty to Divide Services

If you have a single server, holding different apppcations this can increase the possibipty of the services to crash with each other and increasing the fail rate of the server. If you virtuapze this server, you can put apppcations in separated environments from each other as we have discussed previously.

Disadvantages of Virtuapzation

Although you cannot find many disadvantages for virtuapzation, we will discuss a few prominent ones as follows −

Extra Costs

Maybe you have to invest in the virtuapzation software and possibly additional hardware might be required to make the virtuapzation possible. This depends on your existing network. Many businesses have sufficient capacity to accommodate the virtuapzation without requiring much cash. If you have an infrastructure that is more than five years old, you have to consider an initial renewal budget.

Software Licensing

This is becoming less of a problem as more software vendors adapt to the increased adoption of virtuapzation. However, it is important to check with your vendors to understand how they view software use in a virtuapzed environment.

Learn the new Infrastructure

Implementing and managing a virtuapzed environment will require IT staff with expertise in virtuapzation. On the user side, a typical virtual environment will operate similarly to the non-virtual environment. There are some apppcations that do not adapt well to the virtuapzed environment.
