VPS or Virtual Private servers are used to get multiple servers connected to get maximum number of servers for all the users. This is done by virtually splitting the physical server into logical servers so that each server is capable of independent execution. This is mainly used to reduce the cost incurred in procuring many physical servers. Each server in the virtual environment has its own operating system and so they can be rebooted on their own. The VPS is mainly useful in a scenario of web site hosting where each user or client needs a server on their own.

When hearing about VPS, there are two main doubts that come into the mind of any individual. These are guaranteed memory and burstable memory. In the simplest definition, guaranteed memory is the allowable memory for use in a VPS. It can be used whenever the user wishes. The memory allocated in VPS will vary. But the portion of the memory which can be put to use for functioning in VPS is generally called by the name guaranteed memory.

Guaranteed Memory never claims that you can’t use memory more than that prescribed value. Rather it is the least amount that you can make use of. This is independent for each VPS connected to a single physical server. That is, even when the guaranteed RAM available for a virtual server is exhausted, it never affects any other server in the system. And the guaranteed RAM for each virtual server can be made use of at any time completely isolated from other servers in the system.

Guarantee RAM always refers to in the case of actual usage. That is if the required use of memory for the working is less than the guaranteed memory, then the memory can be put to use to the maximum limit. This is because the actual use is less than guaranteed memory.

Guaranteed RAM often remains the prime criteria for your selection of VPS services. So make sure that the memory guaranteed is sufficient for your use. This is because often the companies claim a high availability of RAM, but the net available RAM will not be enough for your use. Performance of VPS is directly proportional to the available guaranteed memory. So this should be the condition for choosing in the case of VPS hosting.

Guaranteed RAM plays a significant role in the selection of the platform also. It is always advisable to understand the memory guaranteed by Linux and Windows before making the platform chosen for VPS hosting. There are specific servers that help to burst the guaranteed RAM for use as burstable RAM which makes the total memory availability more.
