Bemefits of Datacenter Virtualization
Lately, cloud computing and the Internet of Things monopolize news from the media specialized in technology. It could be understood that the interest of the companies when approaching the planning of the IT architecture also focuses on these concepts.
However, it is enough to chat with many of the heads of many Spanish SMEs to get their feet on the ground and see how their IT evolution is much slower and, for the time being, a good part of them need to implement technologies with less media impact but fundamental to start your digital transformation and gain competitiveness. Among these, the virtualization of key servers.
And it is because there are still many organizations that suffer from the complexity and ineffectiveness of distributed environments, with different and varied servers and storage, which prevent data flow smoothly by their applications.
This translates into slow access to corporate systems, residing in different silos, bottlenecks and inability to share information between different business areas. As a result, decision making is also slow. As slow as the administration and maintenance of each of the teams. With the usual risk for business continuity, both due to the difficulty to make and improve backup, recovery and disaster recovery processes and to ensure the high availability of the applications.
Benefits of Virtualization
The benefits of server virtualization are many and impact both IT operations and business. We point out four that are critical:
- High availability and application performance. The dynamic flow of resource use (RAM, HD, computation) between the different VMs ensures the high availability of virtualized applications. Being centralized in the same environment, they are easy to monitor using a single management software, which allows responding quickly to any incident.
- Savings in equipment purchases and time. A single server can host dozens of virtual machines with the same features as physical computers. In addition, the complexity of IT administration is reduced to the maximum, since the deployment and provisioning of VMs is automated, through a single administration console, following the needs of each application, service, business area, etc. Freed from operational routines, the IT team can engage in other, more valuable tasks.
- Reduction of energy costs and physical space. Having to acquire fewer physical servers entails a significant decrease in electrical costs as well as in square meters where they can be located, either in the facilities themselves or in external CPDs.
- An environment to innovate without risk. As each VM is an isolated repository, these become ideal scenarios for testing. Even something as basic as updating a system is no longer a risk. Let's imagine that we want to update the ERP. It would be enough to make a copy of the VM where it resides in another VM as a backup, and apply the update. If there is a problem, we could simply reinstall the copy made.
