Virtual hosting is a method that web servers use to host multiple domain names on the same computer, sometimes on the same IP address, while maintaining a separate management of each of these names. This allows sharing of server resources, such as memory and processor, without requiring that all services use the same host name.
The world of web hosting is huge and includes many offers. Virtual server is another option of accommodation which offers many advantages.
Here are 5 advantages of virtual hosting
1. Increased Operating Rates
A good server should have an operating rate 99.9%. Virtual servers can maintain an operating rate as stable as this – even higher, depending on circumstances. With the migration of servers, it is possible to perform maintenance of the equipment during working time. To do this, simply transfer the application on another operating cycle, thus avoiding interruptions in operation, which is of course desirable. This is one of the main advantages of virtual hosting.
2. Energy Savings
Electricity and energy can be expensive when running a webserver. Thanks to virtual servers, companies could save energy and electricity, and thus money. A simple way to see is as follow: Virtualization of physical servers into virtual servers results in a reduced number of physical servers. The savings come with less cooling costs, less need for space within the data center, and of course, reduced electricity bill in general. Each of these factors may correspond to substantial savings if they are conducted each month.
3. Faster Integration of Backups
Regardless of precaution taken, sometimes a component can fail. For hardware, this is unfortunately inevitable. When this inevitability occurs, we must quickly proceed to “Disaster Recovery”. On virtual servers, disaster recovery is usually done by automatic process, which has the advantage of requiring interruptions very short time and little work. Another advantage is the ability to test a real failure. Many hosting providers make these tests available.
4. Application Isolation
On physical servers, an application is usually located on a server. Even integrating multiple virtual servers on a physical server, it remains possible to isolate applications. The resources required by these applications can be precisely calculated, allowing optimum use the fact they are fully utilized and that there is no under-utilization of individual servers, which is often the case with physical servers. This is another great advantage of virtual hosting.
5. Reduced Server Deployment Time
Moving to virtual servers enables extremely rapid deployment. It is possible to create models for structural and safety rules. The rapid migration of servers and transferring data it requires are very fast. This results in a very rapid deployment, which all customers and end users love.
The advantages of virtual hosting are substantial. Although the technology is relatively new, it has been used for over decade with great success. In addition, the method has undergone numerous improvements which make it even better today.
