Performance Recent advances in hardware and software have removed some of the performance concerns associated with virtualisation Performance guarantees: If you have a database transaction requirement of a few milliseconds, it is very dif cult to provide that guarantee in a virtualised environment. Flexibility Live VM migration without downtime Fault tolerance Management of virtualised technologies VM action log VM snapshots Isolating work and home smartphones on a single physical handset Security Ability to isolate data and applications corresponds to another aspect of the technology Isolation enforced at the lowest level Among organisations currently using virtualisation, business-critical applications are now beginning to come into the limelight. Corporations are most willing to virtualise Web, databases and e-mail applications. Enterprises are willing to place sensitive applications like HR, accounting, ERP and CRM into a virtualised/cloud environment. Security, disaster recovery and governance are road blocks in virtualisation adoption. When it comes to actually implementing virtualisation and cloud computing solutions, organisations often discover it a complicated encounter. Actually, most of them discover it necessary to solicit the help of a third party to be able to completely apply their solution. According to Gartner, the overall virtualisation market reached a healthy $2.7 billion in 2011 and it is expected to grow to $6.3 billion by 2014. The price of handling virtual environments may be higher than predicted because, as usage improves, the price of handling hosts may stay the same or increase as companies come to grips with technological innovations they haven’t formerly dealt with. In order to truly make use of virtualisation, push up the amount of virtualised hosts and rely on the technological innovations to assist mission-critical applications, corporations must modify their virtualisation techniques to account for the changes this technological innovation brings to the hosting server room.
