Virtual Data Center is What  meant by VDC
 

overview

 
  • VDC is a symbol of Virtual DataCenter which described as a group of cloud basic
                 resources made for project business needs.
  • There are main resources which are:
  1. the processor which is CPU
  2. memory which is RAM
  3. storage which is the disk space
  4. networking which is the bandwidth

 

 

  • they are an image of the physical data center,
 
that ends with servers, storage bunches and lots of networking compounds,
 
all which stay in virtual space as it hosted by one or more actual data centers.

What are the benefits of the Virtual Data Center?

 

*COST:

 
Costs reduced from using a Virtual Data Center, not low as you no longer have the cost of buying the servers,
provisioning and servicing them. Although, there are other costs will save on,
not least your in-house IT team will no longer require servicing your in-house data center,
which either will free up their time or if you have an MSP,
they do not need to pay for travel time to and from your location to perform maintenance and upgrades.
 

*Saving Energy:

 
Datacenter uses a lot of power, not least to keep everything running cool. You may not be a “green” or into tree-hugging, but no matter, you will save a great deal of money on your power bills, besides to helping out the environment.
 

Increase the Life of Legacy Applications:

 
You may have more than one old application running somewhere in your business.
operating off a 10-year-old PC covered with dust, set up by an IT admin whose name you can’t recall!
 
Still, you still get many usages out of these old applications and changing them over may
not be within your budget, or the business disruption is too much to handle right now?
 

So, move them over to a virtual environment, and this will allow them to continue to run

and usually with enhanced uptime. It will not prevent the need to tackle them,
but you will and extend their useful life to your business.
 

Scalability:

 
As your servers are now virtual, it is simple and easy to start up new ones as your business needs dictate.
This allows the user to run business applications that he could not find the budget for because
you would have had to include the cost of buying and maintaining the hardware to run them on.
 
A Virtual Data Center allows you to build and move on more, faster than when you operated physical machines.
We could describe it as a simple matter to create a new virtual server,
and be deploying business applications, or create new ones, is a lot easier and faster too.
 

Server Consolidation

 
  • As increasing the number of resources available to your business, you will enjoy the benefit
  • of being able to merge and optimize server resources.
 
  • Moving over to a Virtual Data Center means a reduction in the physical machines, but, this does not mean
  • they are now redundant – consider using them as a test environment for your in-house team.
 
  • Old-style IT doctrine also means, one application/one server, for example, Microsoft Exchange,
  • which done to separate applications, but, this resulted in “server sprawl” and significant
  • under-utilization of server resources while adding to the cost.

 

Protection of the Data and Recovering the Disaster

 
  • By storing data off-site, you are mitigating the risk of loss of data in the event of a critical incident
 
affecting your business premises where you house your physical data center.
 
  •  Besides, making backups is much simpler and faster too, And because the servers are virtual,
  • they can deploy with a few clicks – in the event, a virtual server is down, for whatever reason,
  • another can make life almost.
 

Disadvantages of Virtual Data Center

 

 High Risk of Physical fault:

 
It is great to run very important five servers (as virtual) in one physical server.

So, have you anytime imagine the impact of these five servers by the single hardware failure in the physical

server? It may put all five important servers offline.
It’s a big disadvantage and drawback in virtualization which must considered in producing environment while planning.
 

Do Not Support All Applications:

 
  • Some of the cores applications including few database applications are not ready for virtualization.
  • Sometimes your applications or Operating Systems may act in a virtual environment
without giving any clues.
  • So, you should consider this while planning your server Operating
 
Systems and application implementation make sure it’s certified and supported to virtualization hundred percentage.
