Differences between a Linux VPS and a Cloud Server
Cloud Server uses KVM which is a true virtualization where it operates as its own server with independent kernel and operating systems of the host node. Linux VPS with OpenVZ is a container style of virtualization which relies on the host node’s kernel.
So, what does it mean to you? Linux VPS is like renting a room in the apartment and Cloud Server is owning the entire apartment in a Condo. Giving an example, you are subscribing to internet and wiring around the house is needed. You would need to obtain permission from the owner before you can proceed to do so. This is exact same scenario on a Linux VPS, in the event if there is a need to update the kernel of an operating system, only the service provider can perform the task and all the tenants on this server will be affected during the update if reboot is required.
However, it’s not likely to happen for a Cloud Server instance. As explained, Cloud Server runs an operating system with the kernel independently, you can update and reboot the server at your own convenience.
Both Linux VPS and Cloud Server offer good privacy and security. Unlike shared hosting, security issues and performance may be affected by other websites hosted on the shared server will not likely happen to Linux VPS and Cloud Servers. However, it is known that Cloud Server has better isolation compared to Linux VPS, the fact that it own an independent Kernel.
The performance of a Cloud Server is usually better compared to Linux VPS, due to the limited number of guests can be hosted on one physical server. However, it’s difficult to make an apple to apple comparison because the number of guests on a Linux VPS server can be lesser at time, and performance remains good during this period. Nevertheless, Cloud Server will offer consistent performance and guaranteed resource throughout, unlike Linux VPS.
Both Linux VPS and CLoud server are SSD based. Solid State Drives are much faster than traditional hard drives. Which really speeds up performance of your Linux VPS and Cloud Server, because anything being written or read from the drive happens so much quicker.
