What is Cloud Computing?
Cloud computing can be described as a combination of virtualization servers providing scalable services, applications, storage and infrastructure for multiple clients over the Internet.
How can Cloud Computing help with efficiency?
By combining cloud computer clients the efficiency per physical hosted server is improved greatly. Consolidation of 10 virtual servers :1 physical server and 40 virtual :1 physical server for desktop clients
is possible. Servers, desktop clients and telephony can be virtualized. End users can use thin clients for computer and telephony activity for further energy efficiency. Modern virtual server environments can allocate
resources as demand requires including powering down physical servers when requirements are low automatically.
Virtual telephony with multiple clients can handle 1000's of users from the same hosted VOIP hardware. Not having a local PABX phone system reduces energy consumption and cooling requirements. Business phone
lines can be replaced by business broadband connection saving in phone line rental fees. Some VOIP telephony can reduce long distance phone call charges by using the business wide area network for transport.
Economy of scale can be used in charges of phone calls. VOIP handsets can be connected to the local area network (LAN) and the local computer. This can half the cabling requirements per work point.
