Shared hosting & VPS hosting are having many common features.
Both the hosting services offer some level of compartmentalization with a view to separate a particular user’s files & services from rest of the user’s files & services
Both the services provide an economical substitute for dedicated hosting
Both the hosting services permit a single server to offer services for multiple users
Now, a contrast between VPS andservice is put forward below:
Shared Hosting is usually Linux or Windows based which offers a fundamental level of file system & process compartmentalization Whereas VPS hosting provides Xen Linux & OpenVZ virtualization.
Accounts linked to shared hosting services share all of the available hardware resources along with the “soft” limits forced by the monitoring software whereashave private servers allocated with adequate disk space & independent of memory of any other location on the hardware node. In spite, the potential for individual accounts to influence the performance of hardware node still prevails. Hard limits are set in a manner so that monitoring capabilities are enhanced minimizing the chances of single user activity impacting rest users.
Shared hosting services have wide range of plans starting from plans that range from minimum memory allocations & bandwidth up to unlimited bandwidth and memory allocations. No matter what plan is chosen, the hosting account is likely to be residing on the very same hardware alongside many other accounts with various locations. On the other hand, Virtual private servers are automatically scalable. Irrespective of whether you require a minimum allocation to operate an easy to work e-mail server or run a VPN end-point or even run a web server with adequate resources, VPS hosting service offers a plan to meet all your requirements. The VPS Link accounts are sequestered through plan allocation on the high-end hardware with a view to make sure users get better performance as compared to shared hosting.
Inherently, it is impossible to make shared hosting totally secure as multiple users are having the ability of uploading & downloading files that can be executed under the very same operating system instance that supports the rest of the users’ accounts. This means, there exists the possibility of exploit by a malicious user to gain access to data of the other users. On the other hand, VPS hosting service is a lot more secure than the shared hosting service as it offers virtual environments having independent file systems. Moreover, in VPS hosting the administrators are offered the power to implement secured configurations.
