Securing the virtual world

With businesses always looking for ways to decrease costs, improve efficiencies and availability of IT resources, there has been a rapid adoption of virtualization technologies. Virtualization makes it easy to build and deploy new releases and put changes into production. Over the past decade or more, businesses of all sizes have leveraged virtualization to improve utilization and reduce costs. In addition, service providers have used virtualization to respond to customer demands and provide capabilities such as instant provisioning, as well as the ability to offer the isolation and manageability of dedicated hosting without reserving expensive hardware for each customer. Today, these capabilities are prerequisites to achieve the elasticity and flexibility of private and public clouds.
