If the VPS you select is unmanaged, then as mentioned earlier, you will have to ensure that the server stays in good health and performs efficiently. If your server crashes or if you face any sort of security issue, be it a virus or a breach, then you will be responsible for restoring your server as the only administrator of the entire virtual private server. Hence, if you are well-versed in the functioning of servers and are knowledgeable with stuff such as rebooting, restarting, shutting down and repairing the server, you should consider opting for unmanaged hosting. On the other hand, if the last sentenced sounded alien to you, then you should consider paying slightly more and opting for a managed VPS.
Fully Managed VPS is a virtual private server that lets you take a hands-off approach. Your hosting company will handle the technical side to ensure the VPS provides the functionality and virus and spam protection you need without any work on your part. They’ll also handle maintenance, troubleshooting, and software installs, saving you time and making sure the job is done with expertise.
A VPS doesn’t just have more RAM, disk space, and a proprietary share of CPU than a shared account. Depending on the provider, some VPS plans offer burstable memory, which is a pool of RAM set aside for extraordinary events. This is the stuff that can help counter the so-called “Digg-effect,” that much-whispered about occurrence that’s the simultaneous hope and fear of everyone who runs a web site. When you have an unexpected high traffic event, burstable memory will call on a pool of reserved, shared memory to satisfy the needs of temporary high traffic. This is not available on shared servers and, while the necessary memory is available on a dedicated server, your site might not get the kind of traffic on a daily basis to justify the expense of a dedicated server. Again, not all VPS plans have burstable memory, so ask your provider if their VPS plans do.
