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.
If you host it in a VPS environment, your site won't share resources with neighboring sites, the way it would with shared hosting. In fact, your site lives in a partitioned server area that has its own operating system, storage, RAM, and monthly data transfer limits, so you can expect smoother, more stable site performance. The sites with which you share your server are far less likely to affect your site—or even take it down altogether—than they would be on a shared site. Knowing how VPS setups operate is just the first step, however. You still need to familiarize yourself with the essential features needed for building a rock-solid, VPS-hosted website.
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.
A2 Hosting offers two VPS options. They are both great options and very affordable. The entry level option is just $9.89 per month, and the Cloud VPS is $15. They are both great choices and will be able to meet all your needs for most entry level or mid-sized sites.
There are numerous open source Linux virtualization platforms based on KVM, while Microsoft has Hyper-V with Windows cloud servers, Citrix maintains the Xen server framework, and VMware has a number of different hypervisor frameworks such as ESXi. Hypervisors permit the managing of multiple web servers independently on shared hardware each with isolated databases, file storage, and I/O request processing.
Installing the OS on HDD storage and low RAM VPS plans can be long and arduous, whereas managed VPS plans are available instantly with the full LAMP stack from shared hosting platforms pre-installed. Setting up a cloud VPS with server stack snapshots is much easier than command line administration, as well as much quicker. In summary, it largely depends on the user preferences of the system administrator which VPS installation approach is pursued or the requirements, budget, codebase, etc. of the website to be supported by the hosting can be taken as overriding factors in decision making.
The answer to this question is a definitive “maybe.” Since you’re looking at this site, you might be a Web designer who has a few sites, an online portfolio, and a couple of long-standing clients whose sites you manage. Is a VPS for you? Well, you’ve most likely outgrown a shared platform, and as a professional, it won’t do to have your site run poorly because another site that you share a server with is using more than its fair share of resources. A dedicated server could be overkill – if you don’t need all the resources on a consistent basis, you may not be able to justify the expense.
