The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
The great news for VPS customers these days is that most web hosting companies offer managed VPS hosting. Here, not only will they set up your server environment, but they’ll also take care of tasks such as software upgrades, security patches, etc. Also, provision time is now greatly reduced and you can be up and running with your VPS hosting much more quickly.
You’ll also Benefit from the Following Features:
VPS hosting contains the best elements of shared hosting and dedicated hosting services. Like shared hosting, VPS hosting puts your website on a server that also has other sites running on it, except that there are fewer sites per server. The sites share the cost of running on the server, which results in a monthly or yearly charge that's less than the relatively high price tag of dedicated hosting.
I can’t say it as a disadvantage of VPS hosting because many of our VPS hosting customers have server administrator to manage their VPS and they manage it in very efficiently manner. But this doesn’t everyone must have server administrator, we have content-rich knowledge base on VPS hosting for our self-managed customers.Also, a managed service option at very affordable price.
