Things that were once impossible are now commonplace, thanks to virtualization technology. It is by far the most effective way to cut IT expenses, while simultaneously increasing efficiency and functionality.
Virtualization is a good idea for any company, from a large enterprise to a small business.
What is Virtualization?
Today’s X86 servers are designed to run only one operating system and application at a time, which means that many servers are required to run even a small data center. In addition, these servers only operate at 5-15% capacity, which is obviously is highly inefficient. As any business owner understands, the ability to be productive and efficient are key to success.
This inefficiency has been the biggest hurdle with IT management. The vast infrastructure required to keep a business up and running eats up a large portion of an operations budget- and that’s just for maintenance. It is nearly impossible to grow a business this way.
Virtualization technology easily and efficiently clears this hurdle, thanks to hypervisor software. Hypervisor software allows multiple operating systems and applications to run simultaneously on one physical server, known as a “host.” This host provides computing resources to each virtual machine (VM) connected to the server. VMs operate independent of each other, which means they behave as separate computers with little risk of damage to the host files and apps.
What are the Benefits of Virtualization?
- Cost to operate cut nearly in half.
- Time needed to provision a new server takes just days (vs. months via the old way).
- Starting up a new application or server no longer needs to be done on nights or weekends. With virtualization, the virtual workload can now be migrated to a new machine with no down time or added hassle.
- Virtual machines are independent of the hardware underneath, which means that Disaster Recovery can be automated. This reduces the need for added equipment and manual labor.
- Dramatic reduction in hardware requirements.
- Each physical server operates at up to an 80% increase in capacity.
Virtualization Services on a Network
Network virtualization (NV) is a way to combine available network resources by splitting up available bandwidth into channels. Each channel is independent (and independently secured) from the others, and may be assigned to a particular server or device, in real time. Every subscriber has shared access to all the resources on the network, from a single computer.
The overarching goal of NV is to improve network security, scalability, and the ability to recover quickly from failure (reduced downtime). One aspect of NV is access control, which is the means of providing secure and customized access for individuals and groups in order to prevent the LAN from being vulnerable external threats. Path isolation, or the way to direct authorized users and devices to the proper secured set of available resources on a virtual private network (VPN), is another aspect of NV that we cover here at Technology Solutions. Our NV solutions can consolidate many physical networks into one virtual network, or segment one physical network into many logical networks.
Security in a Virtualized Environment
When most people think of virtual security threats, they think of hackers. However, the biggest threat often comes from within. Employees are often responsible for the largest security breaches to a company’s virtual infrastructure, usually due to catastrophic mistakes.
Protecting your data is our priority at Technology Solutions. Our team doesn’t focus solely on larger security issues, as oftentimes the little things (like user permissions or VM patching) are what can truly bolster or weaken virtual security measures.
