Virtual Reality Essay
I have chosen to research virtualization and the top benefits of this very topic. In doing so, I will detail topics such as the cloud, older applications, improved disaster recovery, and faster server provisions. I will utilize resources from the textbook, LIRN, and the Internet. Data center virtualization can reduce your costs on facilities, power, cooling, and hardware, simplify administration and maintenance, and give you a greener IT profile. If you’re thinking about migrating to a hosted data center or looking for ways to improve your on-premise data center, I have one word for you: virtualization. Offering profound changes to the way data centers perform, virtualization makes sense on multiple levels. Here are 10 key benefits of data center virtualization.
1: Less heat buildup
Millions of dollars have gone into the research and design of heat dissipation and control in the data center. But the cold, hard fact is, all of those servers generate heat. The only way around that? Use fewer servers. How do you manage that? Virtualization. Virtualize your servers and you’re using less physical hardware. Use less physical hardware and you generate less heat. Generate less heat in your data center and a host of issues go away.
2: Reduced cost
Hardware is most often the highest cost in the data center. Reduce the amount of hardware used and you reduce your cost. But the cost goes well beyond that of hardware — lack of downtime, easier maintenance, less electricity used. Over time, this all adds up to a significant cost savings.
3: Faster redeploy
When you use a physical server and it dies, the redeploy time depends on a number of factors: Do you have a backup server ready? Do you have an image of your server? Is the data on your backup server current? With virtualization, the redeploy can occur within minutes. Virtual machine snapshots can be enabled with just a few clicks. And with virtual backup tools like Veeam, redeploying images will be so fast your end users will hardly notice there was an issue.
4: Easier backups
Not only can you do full backups of your virtual server, you can do backups and snapshots of your virtual machines. These virtual machines can be moved from one server to another and redeployed easier and faster. Snapshots can be taken throughout the day, ensuring much more up-to-date data. And because firing up a snapshot is even faster than booting a typical server, downtime is dramatically cut.
5: Greener pastures
Let’s face it: If you’re not doing your part to help clean up the environment, you’re endangering the future. Reducing your carbon footprint not only helps to clean up the air we breathe, it also helps to clean up your company image. Consumers want to see companies reducing their output of pollution and taking responsibility. Virtualizing your data center will go a long way toward improving your relationship with the planet and with the consumer.
6: Better testing
What better testing environment is there than a virtual one? If you make a tragic mistake, all is not lost. Just revert to a previous snapshot and you can move forward as if the mistake didn’t even happen. You can also isolate these testing environments from end users while still keeping them online. When you’ve perfected your work, deploy it as live.
7: No vendor lock-in
One of the nice things about virtualization is the abstraction between software and hardware. This means you don’t have to be tied down to one particular vendor — the virtual machines don’t really care what hardware they run on, so you’re not tied down to a single vendor, type of server (within reason of course), or even platform.
8: Better disaster recovery
Disaster recovery is quite a bit easier when your data center is virtualized. With up-to-date snapshots of your virtual machines, you can quickly get back up and running. And should disaster strike the data center itself, you can always move those virtual machines elsewhere (so long as you can re-create the network addressing scheme and such). Having that level of flexibility means your disaster recovery plan will be easier to enact and will have a much higher success rate.
9: Single-minded servers
I’ve never been a big fan of all-in-one services. Not only are you looking at a single point of failure, you have services competing with resources as well as with each other. Those all-in-ones are purchased to save money. With virtualization, you can easily have a cost-effective route to separating your email server, your web server, your database server, etc. By doing this, you will enjoy a much more robust and reliable data center.
10: Easier migration to cloud
With a move to virtual machines, you are that much closer to enjoying a full-blown cloud environment. You may even reach the point where you can deploy VMs to and from your data center to create a powerful cloud-based infrastructure. But beyond the actual virtual machines, that virtualized technology gets you closer to a cloud-based mindset, making the migration all the more easy.
Experience the benefits
Virtual machines offer a powerful way to help relieve the typical headaches that plague administrator’s day in and day out. If you haven’t already begun to make use of virtualization in your data center, it’s time you start. Even if you migrate only a simple file server to virtualized technology, you’ll quickly see the benefits — and eventually, you may want your entire data center virtualized.
