(Article appeared in www.aslan.es the 11/01/2010 and written by Xavier Duran virtualization specialist at Nexica and certified by VMware)
Of all the ICT tools that are having more success in these times where is required curbing spending, and maximum use of available resources is, without doubt, the virtualization.
Virtualization is basically a technology that allows software and hardware transformation and the execution of multiple SO in a single physical machine. The benefits derived its implementation are:
-
Time saving: New servers deployment and fallen services recovering is faster.
-
Economic savings: It reduces infrastructure acquisition costs by increasing hardware efficiency, utilization and flexibility. Furthermore, by maintaining a smaller infrastructure, it also reduces real estate requirements, power and cooling, with consequent and significant reduction in IT costs.
-
Energy saving: reducing infrastructure, the energy expenditure is lower, whether they are housed in their own offices or in a data center like Nexica.
For a managed service provider as Nexica, virtualization is one of the factors that allows to provide ICT infrastructure as a Service (IaaS), a model within the cloud computing services that is having a great reception because:
-
It offers to the organizations flexibility and scalability as it allows to enjoy on-demand services tailored to companies requirements at any stage of their business.
-
Allows "pay as you go" formula.
The IaaS model is very suitable, for example, for software developers who want to offer to their customers Software as a Service (SaaS) with multitenancy distribution model that allows to serve all customers in a single platform.
Virtual infrastructure solutions are ideal for production environments and operate independently of the hardware and operating system, providing customers and widely deployed platform choice.
Conclusion
In summary, combining virtualization with a provider that offers a robust technology platform which combines the virtual servers with hundreds of storage devices and physical computers interconnected means access to a wide range of ICT resources (network, servers , storage, applications and services) that can be quickly provisioned with minimal effort and supplied and used on demand. The advantage of having a managed services provider that offers IAAS, allows organizations to have virtualization solutions both ad-hoc and managed solutions benefit from virtualization.
