Creating web site nowadays is a very popular as an essential part of every modern business. Still, there are some requirements in the online world, so the remaining website should be hosted and physically placed. One of the options is using a server that will host the website, but this alternative can be quite expensive. Another option, not so expensive is Server Virtualisation. Most of the servers only use a small fraction of their entire processing capabilities, with server virtualisation a single server can be converted in multiple servers on the same machine. From the idea of virtualisation you place multiple websites in various sizes on a single server. The cost of using this type of service is significantly smaller, thus, using only one server for a single site can be very expensive. Consequently, everyone now decides to go into one server for more sites which doesn’t have to be related to each other.
Companies which are practicing this service of consolidation are enjoying lots of benefits by saving a large amount of space without additional investments in hardware components. So in the meantime, you can upgrade your technology and maintain the required space virtually by reducing costs for maintaining and hosting. Additional hardware systems can be very expensive and extra space is needed. This means you will need less hardware, fewer servers, minimal outflow for modems, cables, besides in long term you can reduce energy consumption dramatically.
The main benefits form virtualisation are:
- Server provisioning
- Data recovery capabilities
- Server backup
- Data availability
- Space recusing and information recovery.
The financial benefits are on top of these. The main ones are a reduction in capital costs because of the need for less IT hardware, and a fall in operational costs thanks to streamlined management. Another aim is bandwidth. A small website that doesn’t need a lot of bandwidth doesn’t need so much space that entire server will offer. Not only it will reduce costs, but it gives the site just the right amount of space needed, without having to pay for any unnecessary or unused space. This is a good reason for companies with smaller websites without any particular plan to grow in the future.
There are a few disadvantages of server virtualisation that can prevent a site from running properly. First is the problem of availability. If all sites owned by just one company are placed on the same server and come down for maintenance because that particular server goes down, all the sites will go down at the same time.
Another difficulty is the security. The majority of the time website is protected and can be accessed at any time with no problems. There are certain times when this isn’t the case and sometimes data from one site becomes viewable accidentally by any other log in user on that server. In practice, the overall experience is quite positive and there is no such thing like data transferring and changing between sites so you don’t have to worry at all if someone may use information from your site or change it. Security is more important for large companies who own national offices and have hundreds of employees, which are continuously updating and using server resources. Essentially virtualisation offers a superior level of security and brings better organization on of all these resources, so at the end you will have more control over all features.
Nowadays flexibility is a crucial skill, especially if you have employees in more different locations that need to enter data separately. Server virtualisations allow multiple accesses to enter data which results with higher levels of productivity and ability to run applications anywhere, anytime with fewer costs in long term.
