VPS: bridging the gap between shared and dedicated servers
Most organizations, take the Forbes’ list of top 500 companies, for example, once started with shared hosting and gradually moved and upgraded their server towards a more advanced one. It takes money to evolve your idea to a business on track, tying down your hands into spending a bare minimum.
However, a lot of companies have, for decades, adhered to shared servers and never shed a tear in mourn of its performance. Meanwhile, there have been companies that continued advancing their tech with time and are blooming equally well. As a clan of professionals, we believe up-gradation becomes inevitable at one point in your business cycle.
Shared hosting brings in numerous advantages like cost reduction, reduced server management, etc., but may cripple in the presence of a notorious neighbor. Shared servers are just dedicated machines that house several tenants to share its resource. Things work pretty well on shared hosting, but only as long as the traffic is less to moderate.
There is another alternative though – A VPS hosting, that shall see our light in the later sections of this blog.
Shared servers host multiple tenants. Say, for example, you live in an apartment that has a common facility for water storage. A new neighbor moved into a flat that had been lying vacant for ages. This new neighbor has a habit of consuming excessive water, showers for hours, and drains all the water of the building, making water a scarce commodity and steering draughts.
The analogy is in regards to a shared server, wherein a traffic surge in any of the hundred (or more) tenants’ website can drain all resources of the server.
How secured could you be living in a building where an outlaw resides, too.
The scenario with Shared servers is tantamount to the one mentioned above. It would take only seconds for malware, Trojans from other websites to break into yours, given the fact that all sites rely on the same machine’s resource.
Sites hosted on such servers are more vulnerable to attack and can be compromised with, in a snap.
It only takes one of the webmasters in your server to misuse the HT access, inflicting damage to all the webpages hosted on the machine. Moreover, the maintenance of such machines poses unmatched challenges to the provider. Many providers are little concerned for these servers and tend to focus more on other profitable servers. Even a small technical glitch in a shared server can steer a mass site-outage.
How can VPS hosting help?
As long as your traffic is meagre, and your business is not solely dependent on your website, there is nothing bothering you. However, websites that attract big crowds are bound to run into problems starting day one.
A VPS bridges the gap between the shared and the more expensive dedicated server and is ideal for companies looking for a dedicated server-like alternatives at a somewhat lesser price.
Unlike shared hosting, a dedicated machine does not share its resources among several webmasters. It’s a no brainer that the latter will be more expensive, but can offer supreme security and performance. Running a dedicated machine may not always be economically viable, especially for small business that has only recently come into existence.
A VPS mimics a dedicated server hosting environment by allocating an exclusive set of resources to a particular tenant. The difference being, the computing resource is only virtually separated among tenants through software or an array of codes.
Benefits you can draw from a VPS
Virtual servers converge profits from a shared server with that of a dedicated server, and in the process, provide an intermediate machine that is not only affordable but also delivers performance in close proximity to a dedicated server.
It is worth noting that a VPS is also shared hosting, but with doled out resources. Hence, if a shared hosting and a dedicated machine are two ends of a see-saw, VPS is the fulcrum amidst the two ends.
Disadvantages with a VPS
From a financial standpoint, virtual private servers cost a lot when compared to a shared. While the cost is not as high as the dedicated, it is still very high, and can be prohibitive for startups constrained with funds.
Each virtual environment has its own Operating system – which could be either Linux, windows, or any other OS. Different operating systems running on a single server create a heterogeneity that makes it difficult for the provider to manage.
Sum it up
Though a VPS creates an illusion of being a dedicated server, it is not the same. However, it is possible to do almost anything on a VPS that a web developer can do on a dedicated server.
