اسلاید ۶: ۲۰irtualizationAndCloud6The Traditional Server ConceptSystem Administrators often talk about servers as a whole unit that includes the hardware, the OS, the storage, and the applications.Servers are often referred to by their function i.e. the Exchange server, the SQL server, the File server, etc.If the File server fills up, or the Exchange server becomes overtaxed, then the System Administrators must add in a new server.

اسلاید ۷: ۲۰irtualizationAndCloud7The Traditional Server ConceptUnless there are multiple servers, if a service experiences a hardware failure, then the service is down.System Admins can implement clusters of servers to make them more fault tolerant. However, even clusters have limits on their scalability, and not all applications work in a clustered environment.

اسلاید ۱۱: ۲۰irtualizationAndCloud11The Virtual Server ConceptVirtual servers seek to encapsulate the server software away from the hardwareThis includes the OS, the applications, and the storage for that server.Servers end up as mere files stored on a physical box, or in enterprise storage.A virtual server can be serviced by one or more hosts, and one host may house more than one virtual server.

اسلاید ۱۲: ۲۰irtualizationAndCloud12The Virtual Server ConceptVirtual servers can still be referred to by their function i.e. email server, database server, etc.If the environment is built correctly, virtual servers will not be affected by the loss of a host.Hosts may be removed and introduced almost at will to accommodate maintenance.

اسلاید ۱۳: ۲۰irtualizationAndCloud13The Virtual Server ConceptVirtual servers can be scaled out easily.If the administrators find that the resources supporting a virtual server are being taxed too much, they can adjust the amount of resources allocated to that virtual serverServer templates can be created in a virtual environment to be used to create multiple, i
