Today we will analyze in detail what a virtual data center is, how it is technologically implemented, and what is better than a physical data center and VPS/VDS.
An Understanding of the Virtual Data Room Center and What Is It Used for?
Today, the term “virtual” is quite common. Virtual infrastructure, virtual machine – which we have repeatedly talked about in our blog articles. The time has come to get acquainted with the concept of a virtual data center. What is it, what tasks does it solve, and what advantages does it have? You will find answers to these and other questions in today’s material.
A virtual data center (data processing center) combines virtual resources in the form of servers, networks, and disks for storing, transmitting, and processing data. On the basis of the data center, an IT infrastructure of any scale and complexity is formed. In terms of its capabilities, it is not inferior to similar solutions using physical equipment.
A data center (DPC) is a centralized physical location that houses corporate computers, networks, storage, and other IT equipment to support business processes. The computers in the data center contain or support critical business applications, services, and data. Modern companies use computers in almost all aspects of doing business:
- for communication;
- information storage;
- accounting processes;
- everyday business tasks.
Resources are managed by means of a self-service portal both over the Internet and via dedicated communication channels, where the customer can independently change the number of resources provided, create virtual machines, configure the network, create the required network topologies, perform backups and other tasks. This allows you to fully control the services placed in the cloud and not depend on the technical support of the service provider in terms of providing additional resources.
Representing a virtual infrastructure in the IaaS model, a virtual data center is used to implement almost any task. But most often, companies focus on testing and development, data placement and storage, the connection of backup resources under peak load conditions, creation of a backup data center, equipment replacement, and migration.
The Virtual Data Room Center as a Multilayer Virtualization System
Events such as the transfer of employees by commercial and state companies to “remote work”, the need to transfer part of offline events and user actions online, and the redirection of marketing budgets to digital channels have become challenges that require prompt solutions and high capacities from data processing centers (DPCs), which they were unable to cope with.
If you imagine a virtual data center schematically, it will look like a multilayer system, where each layer is a separate virtualization level with its own capabilities:
- Network virtualization guarantees the interaction of virtual servers with each other, which allows you to build a single infrastructure and ensure data exchange.
- Storage virtualization gives you the ability to manage storage and optimize the use of disparate and disparate devices.
- The virtualization of computing resources allows efficient use of available capacities in accordance with business tasks.
Since virtual data centers are built on a public cloud using enterprise-grade virtualization technology such as VMware, customers share virtual data center resources between OS, applications, and services just like in a regular physical data center, which allows them to solve business problems without worrying about the reliability and availability of the infrastructure. The cloud infrastructure started out as a platform for hosting public applications. Businesses have seen the benefits and have begun moving their internal business applications to the cloud.
