In a world of exponentially growing data, businesses not only need to store securely, but also operate flexibly and efficiently. Virtualization was born to solve that problem. This is a technology that allows a single physical server to run multiple virtual servers (Virtual Machines – VMs) at the same time, each operating as an independent system.
Thanks to a middleware layer called the Hypervisor, hardware resources (CPU, RAM, storage, network) are dynamically and flexibly divided between virtual machines. This helps businesses maximize hardware performance, reduce the number of physical devices and simplify operations. Virtualization is considered the “heart” of the modern data center, the first step on the journey towards Cloud Computing, HCI, and other intelligent infrastructure models.
Virtualization is not limited to servers. In the data center, this technology is applied at multiple infrastructure layers:
Storage Virtualization: Combine multiple physical storage devices into a single virtual storage space, making it easy to manage and expand capacity.
Ảo hóa lưu trữ (Storage Virtualization): Kết hợp nhiều thiết bị lưu trữ vật lý thành một không gian lưu trữ ảo duy nhất, giúp quản lý và mở rộng dung lượng dễ dàng.
Network Virtualization: Create flexible logical networks on the same physical infrastructure, enhancing security and optimizing data flow.
Desktop Virtualization: Allows users to access the work environment remotely, increasing flexibility for the hybrid working model.
As a result, the entire data center can be managed, allocated, and scaled using software alone, without the need for complex physical intervention.
OUTSTANDING BENEFITS OF VIRTUALIZATION FOR BUSINESS
a. Optimizing investment and operating costs:
Virtualization helps businesses reduce the number of physical servers, saving electricity, space and maintenance costs. This is a great advantage in the context of rising energy prices and the need for constantly expanding infrastructure.
b. Increase resource utilization efficiency:
Instead of letting the hardware run underloaded, virtual machines can dynamically share resources according to actual needs, ensuring optimal CPU, RAM, and storage usage.
c. Easy to expand and flexible in operation:
Enterprises can create additional virtual machines in minutes, serving testing, deploying new applications or increasing system load without investing in new hardware.
d. Ensure safety and fast recovery:
Virtualization allows snapshots and backups of entire virtual machines, helping to recover data or convert systems within minutes in the event of a problem.
e. Increased automation and integration:
When combined with centralized management technology and AI, virtualization helps the system self-adjust, distribute resources and optimize operations in real time.
Virtualization is not only a cost-saving technology, but also the foundation of smart digital infrastructure. Cloud computing models, HCI (Hyper-Converged Infrastructure), or SDN (Software-Defined Networking) are all based on the principle of abstracting physical hardware into virtual resources that can be expanded on demand.
Thanks to this, businesses can build a hybrid cloud environment, flexibly connecting between on-premises and public cloud. This helps meet the requirements of continuous operation, global distribution and ensuring data sovereignty in the AI and IoT era.
In Vietnam, many technology enterprises and infrastructure providers such as VNPT, Viettel, FPT, DCH have deployed complete virtualized data center platforms.
These systems are helping domestic enterprises transform digitally faster, deploy services more flexibly and be ready to enter the AI and Big Data era.
In particular, with the emergence of new generation data centers in Ba Ria - Vung Tau, Ho Chi Minh City, Hanoi, the application of virtualization will be an inevitable step to improve operational efficiency and optimize national infrastructure.
If the data center is considered the brain of the digital economy, then virtualization is the nervous system that helps that brain operate more smoothly, flexibly and intelligently. Thanks to this technology, businesses not only reduce costs, but also open up the possibility of autonomy, expansion and unlimited creativity in the digital space. Virtualization is no longer an option – but a prerequisite for any sustainable digital transformation strategy.
