E-learning and e-teaching system are what help development in Competencies

It’s hard to believe how far we’ve come in the virtualization industry. What was once considered a niche technology used only for development and testing is now used for production work- loads and even business-critical applications. The VMware vSphere platform is capable of sup- porting nearly any virtualized workload with very few obstacles standing in the way of close to 100 percent virtualization. Today’s workloads are more demanding than ever before. Email servers frequently require large amounts of memory and CPU resources in order to handle the large volume of email that we all deal with on a daily basis. Database servers often require large amounts of memory and storage resources, from a capacity perspective as well as performance, to meet the demands of a business. And newer technologies, such as virtual desktop infrastructure (VDI), have intro- duced signii cant demand for resources in vSphere environments.
