Modern software, from operating systems to applications, constantly demands more. More data, more processing power, more memory. Virtualization makes a single physical piece of hardware act like multiple machines, saving you the cost of more servers and workstations.
Virtualization is a process that allows you to make multiple simulated environments from a single piece of physical hardware using a hypervisor. Each simulated environment is known as a virtual machine and can be treated as its own dedicated resource, even though they are all operating as files out of the same piece of hardware.
History of Virtualization
Virtualization technology actually dates back to the 1960s. It was used to give multiple users simultaneous access to a single computer entity, but the technology didn’t become widely used until more recently.
In the 1990s, companies accumulated different servers from different vendors, each server handling one task and all servers winding up underused. Virtualization took off as a way to allow one server to act as a host to multiple different virtual machines, which allowed for the more efficient use of the servers.
Benefits of Virtualization
The benefits of virtualization are both significant and numerous.
- Hardware Optimization: Rather than use three different servers for various software and applications, one piece of hardware can act as three different machines to handle them all. One machine operating at 90% capacity is more efficient than three pieces of hardware running at 30% capacity. This frees up the other two for different uses or can reduce maintenance and cooling costs. Additionally, you can also provide hardware redundancy across those same three servers if needed.
- Upgrading: When your machines are virtual, you can upgrade them with a mouse click, rather than needing to install new hardware on a real, physical machine.
- Disaster Recovery: The virtual machines, though they act like real machines, are simply files on your host server. This means that the entire virtual machine can be backed up, from data to installed programs to the operating system itself. This can also lead to faster restore times in the case of a disaster.
- Efficient Use Of Resources: Because your virtual machines are all running on the same hardware, they can share resources. If one virtual machine needs a bit more, it can take them from another machine that doesn’t need as much at that time.
Now that companies are realizing the benefits of virtualization, it is becoming an increasingly popular and cost-effective best practice.
