The terms VPS and Cloud server are usages which often burrows ambiguity in some contexts. But the right term to describe our cloud product would be Cloud VPS, as it’s a virtualized server, on redundant cloud infrastructure. In this section we will try and coin their right definitions and positions. Before we go into the differences between VPS and Cloud server, let us look into how same they are. • Both VPS and Cloud Servers use virtualized environments. • Both VPS and Cloud Servers use resources from a single hypervisor. Virtualised environment supports the functioning of both VPS and Cloud servers. Multiple virtualisation methods can be employed to get VPS or Cloud server started, in accordance to which provider you choose. Our software provider, OnApp has support for Xen, VMware and a few others. We’ve chosen Xen for our virtualization platform. Though it is rumoured that cloud servers has resources from multiple servers at its disposal, this fact is quite false. Despite the technological advances we still aren’t capable of converge together resources from multiple machines. Thus cloud server too uses resources from a single machine. Why choose Cloud Server over a Traditional VPS? Beyond the similarities that a VPS and Cloud server may share, the Cloud server still emerges out as a prodigy in website business. We will now look into the pros of Cloud server over a traditional VPS Versatility with Resource sizes. Facilitates resource up-gradations on the fly, sometimes even without rebooting Better redundancy Centralized redundant storage The upgradation facilities provided by Cloud server is supple enough to include your changing requirements. If you find your server short of resources during the run time, you could just add more resources to it. This strikes out the need of migrating to another server when met with immense traffic. The traditional VPS environment has your server hosted on a single hypervisor, with the hard drives running in a RAID 10 array. But when it comes to cloud server your server can be hosted on any of the hypervisors on the cloud as your data is hosted on SAN, a centralized storage system. This is where it hits its triumph. If one hypervisor is down your site is redirected to another in function. To add to this counter technique, cloud providers also replicate data across multiple SAN units. This ensures that another SAN is dispatched in case your current one fails you. With these advantages added to what a traditional VPS could offer, Cloud server definitely is worth your consideration. As it comes at a price similar to that of VPS, there is not much room left to deliberation.
