Cloud server vs VPS
Both the Cloud server and a VPS are fundamentally the same. They are virtualized, but in terms of function, they cloud be different. Operating both the cloud server of the VPS are the same, you do need special skill on a cloud server or a VPS.
The major difference is the storage. When you are labelling your service as cloud means the guest machine will move to another host when the resided host has failed. VPS works directly with the local storage.
If the resources are spread to a few hosts like MySQL, Web Server, Tomcat, etc are known as cloud hosting. They could be confusing especially to a beginner. So Cloud server is better? In a certain way, yes if your instance has failed. The guest machine (Cloud server) will move to another host.
There are more points of failure for a cloud server set up. The setup requires more equipment, costs are higher and there are more interconnects. So it is quite a debatable question which is better. Most importantly, you have a backup and you can restore quickly.
However, I reckon a VPS might perform better at the same CPU class due to the shared storage. Even it is a fibre connection, it will definitely cost more. In the industry, many providers jump into the bandwagon using the word ‘cloud’ on their services to get more people to sign up.
As a consumer, we need to ask more pre-sales question if you are buying a ‘Cloud’ service, it could be misleading. Anyway, you can know more about the service what you are paying.
