What is the difference between server virtualization and the cloud? Virtualization is the process of creating multiple virtual environments on a single server. It does this by using virtualization software, which allows multiple operating systems to run on the same server at the same time.

In other words, server virtualization allows you to divide each physical server into multiple virtual servers, which is our commonly used virtual host or vps.

Cloud computing uses virtualization technology. In a cloud data center, a large number of physical servers are actually partitioned, but it is not a virtualized cloud. We should think of the cloud as providing shared computing resources, software or data-as-a-service (SaaS) through the Internet, and its product is what we often call a cloud server.

Characteristics of Virtualization

One of the biggest advantages of virtualization is the ability to reduce capital expenditure and run multiple virtual servers on fewer physical servers. Can make better use of available resources and capacity, thus using the server more efficiently.

In addition, because each virtual machine can run its own operating system, it can run more applications at the same time; in essence, it allows you to achieve more functionality at less cost.

From an operational point of view, virtualization can improve availability. Downtime is reduced because maintenance can be performed on one VPS without disrupting other vps hosts.

Characteristics of Cloud Computing

One of the biggest attractions of cloud computing is cost-effectiveness. Placing the system in a cloud server means that you don't need to invest a lot to build your own data center, so the initial cost is much lower than traditional technology. In addition, cloud computing reduces the costs, storage costs and expenses associated with software updates.

Scalability is another advantage of cloud servers. You can immediately expand your computing resources to meet your needs. This will be very helpful for those enterprises with seasonal peaks or those with occasional peaks.

Backup and recovery are also easier to perform in the cloud server. Backups can be carried out automatically and continuously. With snapshot backup and fast recovery, virtual machines can easily and quickly migrate between clustered servers, ensuring that systems and mission-critical applications stay running. It is far better than the disaster recovery methods required by traditional servers.

The ultimate advantage of cloud computing is that it can be easily deployed. The entire system can be fully operational in a few minutes, and the rapid deployment of the cloud means that it provides a faster, more efficient, and more cost-effective disaster recovery model without having to maintain a redundant center on other sites.

The CVM is simple and efficient, and its processing capacity is flexible and scalable, which helps users quickly build more stable and secure applications, improve the efficiency of operation and maintenance, and reduce IT costs.
