VPS Hosting vs. Shared Hosting

Why choose a VPS over a traditional shared hosting solution?  While there are similarities between the two hosting technologies, there are also several significant differences that make VPS Hosting a superior option as compared to shared hosting.  

In order to fully appreciate the extended capabilities that a VPS Hosting solution offers you, a quick review of how they two technologies are similar is helpful.  Here is a brief list of their similarities:

  • Both technologies provide the ability for a single server to provide services to multiple clients or users
  • Both technologies provide segmentation of each customer’s data, files, services from the visibility and accessibility of other customers on the same shared server.
  • Both technologies offer a much more affordable option as compared to using a dedicated server.
The similarities of the two solutions do not extend much beyond this.  Let’s now compare the two and see why VPS Hosting offers a vastly superior solution in terms of functionality, performance and future growth.

Resources

Shared hosting solutions rely on a total pool of resources that span across all of the server’s hardware.  Each customer is allocated a certain portion of the system’s hardware resources and this limit is monitored and policed by the shared hosting platform software that the provider has chosen to use.  This technology is inherently flawed in that it leads to overselling, resource hogging and eventually all customers on a single server fall victim to one shared hosting customer being hacked or abusing their “share” of the overall resource pool.

This is not an issue with VPS Hosting.  Virtual Private Servers have their resources provisioned physically and not virtually.  This means that each VPS customer has a dedicated portion of the overall server’s disk, ram and cpu.  Hardware provisioning ensures that each customer is guaranteed their paid resources and that no other customer can impede upon those resources.  Should a customer on the server receive an overload of traffic, resources, etc. then only that customer’s VPS is affected.

Scalability

Shared hosting accounts years ago would have reasonable bandwidth, disk and various other resources that ensured customers would be able to easily and reliably expand their available resources as their hosting needs grew.  In recent years shared hosting providers have opted for a universal “Unlimited” type hosting plan in order to remain competitive in their aging market.  This results in a free-for-all hosting situation where everyone ends up competing for the same resource pool that is still limited to the hardware within any single server.  Customers end up with no true guarantee of resources and not always seeing an improvement when upgrading their accounts.

VPS Hosting doesn’t have this issue since it has a foundation of hard resource limits that are clearly defined and easily expandable.  If a customer upgrades their VPS account then they are guaranteed a new portion of the servers resources that only they have access to.  This ensures that their applications and hosting needs grow as required and performance increases as well.

Operating Systems & Applications

With a shared hosting account, you really have no control over the operating system that the provider is using as the underlying framework for your account.  In most cases, you also have no direct access to the operating system to perform advanced configurations or troubleshooting.  You can also be limited to which applications are available and compatible for your shared hosting account as certain applications run on certain operating systems and if you’re application requires a certain OS, then you can never be certain that it will be compatible.

With a VPS you can avoid this issue and uncertainly all-together by hand-selecting the operating system that you will use as well as the applications that you would like to run within it.  You can choose from both Linux and Windows templates and a variety of pre-made application templates in over 100 variations.  These can all be installed and deployed with a single click with no manual installation if you like.  

Security

Since shared hosting relies on a single filesystem for many users, it is incredibly vulnerable to exploitation and attack.  If a single customer is compromised then it can lead to the entire server being compromised and all customers that are also hosted on it.  There is also the possibility of the provider providing shell access to a customer who may use the access maliciously or inadvertently damage the server in a way that affects other customers.  

With a VPS you are ensured that your data and filesystem is completely isolated and secure from other VPS customers on a single server.  The VPS runs in an isolated environment on the server that has no shared resources or communications with other VPS customers on that server.  Should another customer be compromised, it will have no impact on you, your server or your data.
