With VPS Hosting, there are multiple instances of separate operating systems on a machine—thus giving you your own virtual private server. So while you still may be sharing a physical server at the data center, with your own virtual operating system, you’re able to have dedicated resources such as RAM, bandwidth, and disk space. In other words, the environment mimics having a dedicated server—at a lower cost!
You’re paying more, so there SHOULD be a minimum uptime guarantee and better server speed. Look for a host that offers 99.5% at a very minimum, although ideally, I’d rather go with someone who offers 99.9%. Search through some reviews as there are many who have put this to the test. For example, any of WHSR’s many web host reviews include an uptime record as one of our key tests.
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.
A longstanding company which won’t disappear overnight, and the low-level offers can safely accommodate projects of a smaller scale. Just keep in mind that you are on your own, even on a managed VPS service, as I wouldn’t rely too much on GoDaddy’s live assistance for anything. Indeed, the company knows how to cut a deal, but it knows equally well how to cut corners.
Simply put, shared hosting means your site will share the same server as many other sites. It’s usually the cheapest option but comes with limited bandwidth, administration, and performance capabilities. VPS hosting is a more premium option, with the ability for greater customization and increased performance. But, as with any premium service, you’ll have to pay more to get more.
From the above mentioned reasons, it is clear to see why cloud servers are such a favorite amongst the VPS crowd. Not only do they offer several benefits and are more secure, stable and efficient, they are extremely economical as well which is why they are preferred especially by those who are new to the business of running websites and hence, do not have a large or flexible budget.
Essentially, here’s the criteria I would use to judge things – if your site is made up of primarily static, HTML-based content, then you probably don’t need a VPS package. However, if you have a large amount of files stored, multiple sites, dynamic content, and the possibility of major traffic from time to time, then you might consider upgrading to a VPS. It’s a powerful package that allows you to do more than you could with a shared hosting plan, but requires less investment than a dedicated server.
