A number of features and functions make cloud a preferred option over other alternatives. Here is a brief explanation of why you should go for cloud instead of VPS:
Scalability: Scalability is one of the biggest advantages of using cloud servers. In VPS, scalability is directly affected by the resources you purchase, i.e. memory, disk space and processor speed. For example, if you require 32 GB RAM memory but only have 8 GB of it, surely it is not enough. Apart from that, with VPS data migration issue is there, as it usually takes a long time to do so. Recovery time is also an issue because of the fact that your data is stored locally if you use VPS, and it might take some time to recover your data if you relocate to a new server. Cloud servers, on the other hand, are capable of storing huge amounts of information unlike VPS. What’s more is that all the data is centralized, and the downtime is eliminated in case of data migration. Cloud allows you to move to higher or lower levels across a particular server. Cloud hosting utilizes your resources in the best possible manner and permits installation of vertical or horizontal development infrastructures.
High-Availability/Accessibility: VPS does not offer high availability to users, while cloud servers guarantee it. Higher availability is possible in the scenario where all the servers are interconnected and synced. The distribution of resources across so many machines ensures that they are always available, thus resulting in higher availability. Because data is centralized, even if one of the nodes stops operating, the hosting server can be accessed through any web server on the internet, thus eliminating downtime. Moreover, if one process ceases to work, the Self-recovery Cloud comes to the rescue right away on another web server.
Cost: Usually, VPS costs the same as Cloud and sometimes even more than the latter. With Cloud, however, you get improved performance, scalability, high availability and accessibility, more flexibility and many other features missing in VPS.
Usefulness: If you use VPS, your host company or service provider will store your data on a randomly chosen node, and it will just be a matter of time before that node crashes. If it does crash, you will need to migrate to another node, which is quite a time-consuming process and could take a few hours. This is because in VPS, storage is not centralized which largely reduces efficiency. This is not the case with cloud servers, in which you do not need to migrate even if the sources are being excessively used by other users. If you require more resources, you will have them without having to wait; it means that there is no downtime in cloud hosting.
