>>>>>>> To be honest with you i know it does ,, Because of the In the simplest terms, virtualization is the practice of emulating a fully functioning server (known as a guest OS) via an application executing on the host OS of a physical server. The VM (VM) running the guest OS is delivered courtesy of a VM software application and can either be isolated, such as in a test or development environment, or be made available to the rest of the network as an independent server. Either way, fewer physical machines will be in the server room than the number of logical servers available to clients.
Because a VM's guest OS can have applications installed and can provide network services to the rest of the network, a major benefit of virtualization in production is that a single physical server can serve multiple purposes on the network. Maintaining fewer robust physical servers, each providing multiple services, is more economical than supporting several physical servers, each dedicated to a single purpose. By consolidating services and applications, you can reduce ownership costs and power consumption while supporting a mix of physical and virtual network services within your environment. Centralized administration with the help of VM management utilities, such as Microsoft System Center Virtual Machine Manager (SCVMM), can reduce administration overhead while portable VMs lower the cost and downtime of disaster recovery, hardware migrations, and upgrades.
as my brother Emad sayed "By consolidating services and applications, you can reduce ownership costs and power consumption while supporting a mix of physical and virtual network services within your environment"
our physical servers can perform more services than before but having all those services in a single server might be causing to some problems
usually the physical server are utilized20% of there resource where in virtualization you can utilize it up to100%
also its very easy to manage and fast to deploy
now when should we host or heir cloud service.
- if you have small organization its better to host your services in any cloud service provider instead of building a datacenter and maintaining costly servers.
- if you are a big organization, I recommends to build a normal and simple virtual systems in your organization
- if your organization is serving so many departments and multi tenant people than you can go for your own private cloud like universities.
