Virtualization and Cloud Computing – What To Choose and When?

There has been a long-standing debate about whether virtualization or cloud computing is the best way forward, and in which case. Since the organization is yours, I will leave the decision to you at the end of this article. What I will present to you are the major differences between the two technologies and comparative pros and cons of both. You will be in a better position to judge your needs and budget and decide accordingly.
The first thing to remember is that virtualization enables cloud computing but both are essentially different. When we are speaking of virtualization we are talking about the creation of a virtual environment within the network or system present in an organization. Even creation of partition within the hard drives is virtualization. The same goes for servers. Using a single application on multiple platforms at the same time is also virtualization. Cloud computing is the process of using the internet to access the resource present at a remote location. The server is hosted by third-party and the organization only hires as much space as is needed.
Let us take a closer look at the various features of virtualization and cloud computing that will allow you to differentiate between the two.
Accessibility – Use of cloud computing system allows access from any place at any time. However, thenetwork is still the major issue. In thecase of network failure of server becoming overcrowded accessibility suffers. Though the same might happen with internal servers as well.
Security – Security is a major issue in thecase of organizational data and application storage. The question here is that whose security you are going to rely upon. If you are to set up your very own virtual server network, you will have to invest in network security. There is no better solution for this issue than the DNS security by BlueCat. Security of the data center is of utmost importance and needs to be taken care of. DNS is a soft target for hackers. DNS security needs to be heightened to keep cyber criminals away from the network.
Dependability – Maintenance will ensure how dependable a network is. In case you have your own virtual network, you will not only have to make sure that the security is in place but will also require a network administrator. Network automation is a better alternative, but it will need high-grade IPAM software as well. It is also essential that you have a network administrator to maintain the physical components of the server. However, this is not the case with cloud network. Server space is for hire and the organization will not have to think of maintenance.
Cost – As already mentioned, virtualization means having the entire network within the organization. This will increase the cost of having a network administrator and putting security features in place. There is also the need to buy all the components. In thecase of cloud computing, you will simply hire as much space as you need and there is no additional cost besides cost for space.
The final decision lies with the management. The above points will allow them to get to a decision.
