VPS vs Cloud Instance Computing
Virtual Private Servers, or VPS, is a technology used that allows multiple small servers to run concurrently on a single computer hardware. VPS provides the isolation so that each one behaves as if it’s on a totally separate machine and does not interfere with each other. Cloud Instance Computing is an extension of VPS that applies Cloud Computing principles to extend the capabilities far beyond that of typical VPS.
In VPS, servers are run in software on top of a single computer hardware. But in Cloud Instance Computing, that single hardware is instead implemented into software and is actually run on top of multiple computers. What Cloud Instance Computing achieves is a highly dynamic nature where you do not have to worry about how many servers can fit on a single hardware without causing major slowdowns during peak hours. Whenever performance is maxed out, you can just add more computers to the group.
A typical implementation of VPS requires that each server be set up with a limited amount of resources. If the limits are reached, an admin. needs to allocate more if the hardware can still accommodate it or move it to another server resulting in downtime. With Cloud Instance Computing, resources can be freely allocated by the software to and from other servers in order to maximize utilization. This is very useful in preventing crashes caused by sudden traffic caused by surges in people’s interest. The growth of a server is even made easier in Cloud Instance Computing because, if the server grows beyond the limits of a single machine, the Cloud software can easily be expanded to span multiple machines either temporarily or permanently.
Cloud Instance Computing also reduces downtime associated with servicing the hardware. A server in the cloud can be easily moved from one physical machine to another without the server going down. The abstraction associated with the cloud allows the hardware to seamlessly transfer all data from one point to another without the end-user even knowing that it happened.
Cloud computing seems to be a very good step forward for both ordinary users and companies providing services. It provides flexibility to both that would not otherwise be available with older VPS systems.
1.Cloud Instance Computing is the next step of VPS evolution.
2.Cloud Instance Computing is highly dynamic while a VPS is not.
3.Cloud Instance Computing can reassign resources as needed while VPS cannot.
4.Servers can be moved while running in Cloud Instance Computing but not in VPS.
