A top consideration in choosing a VPS plan is whether you want the service to be managed or unmanaged. Unmanaged plans are less expensive, but they put the burden of server management on your shoulders. With a managed plan, experts take care of many security and performance concerns. In addition, when you choose the memory, CPU power, and hard drive capacity of your virtual machine, also inquire about the quality and specifics of the physical host it will run on to be sure that the physical host has the power to meet the demands of your virtual machine. Finally, check on the backup plan and redundancy for recovery from any disasters or malfunctions.
Cloud server hosting offers the advantages of increased accessibility and reliability, seamless scalability and potential cost savings, as customers are freed from having to invest in on-premises servers and hardware, and they pay only for the resources they consume. On the other hand, security and lack of access and full control are potential concerns with cloud server hosting.
Cloud hosting is an alternative to hosting websites on single servers (either dedicated or shared servers) and can be considered as an extension of the concept of clustered hosting where websites are hosted on multiple servers. With cloud hosting, however, the network of servers that are used is vast and often pulled from different data centres in different locations.
