Shared vs VPS Hosting

This depends on the goal of your enterprise and amount of resources you expect to use.

Honestly, most of customers have no idea how to use the resources they have, so they order VPS to run a simple vBulletin board, because "their shared package seems to have insufficient resources".

All they actually need is a good compilation to rectify code errors and allow better usage of server resources they are already given .

VPS gives much more control over software, up to reinstalling the OS and configuring each of the tools selected.

Common customers rarely realize and use its full potential but who cares as long as they pay the fees, yes?
 
Very nicely and briefly said.
VPS is also called as VDS i.e. Virtual Dedicated Server that means you have dedicated server virtually with features, almost equal to Dedicated Hosting.
 
I think something that is overlooked with shared hosting when making the consideration to switch to VPS is the management of the VPS. When you buy shared hosting, it intrinsically comes with control panel access and a management package....all this for $5, maybe $10 per month.

The prototypical person making the jump from shared hosting to VPS has two hidden expenses:

1) For the look and feel you're familiar with on shared hosting, you'll need a control panel. Some are free, but most will run you about $5-$12 per month.
2) Unless you're comfortable doing things like reading error logs and rebooting services if they crash or other system administrator tasks, you may want to invest in a management package. Googling how to do things can be a frustrating fallback plan if your site is offline. A management package can cost anywhere between $5-10 per month all the way into the $100s.

Sometimes one or both of those costs are bundled into the hosting package. Backups are another thing to consider, as your shared hosting vendor may have filled that need for you and it's a toss up whether or not your VPS vendor will fill that need.
 
I prefer VPS but to each their own. I just find I have more "control" when using a VPS and as such I feel it satisfies my needs a lot more than a shared hosting
 
It is possible to oversell the resources for VPS hosting. This depends on the virtulization technology. You need VPS when you can't host your website on the shared hosting server due to more resource requirements or additional software which can't be installed on shard hosting.
 
In the shared hosting you are sharing the server specifications with other user. Shared hosting usually has usage limits and extensive reliability features such as IIS, Apache Tomcat, PHP and others.

In the VPS hosting you will have full control and more customization settings of resources compared to the shared hosting servers. For example you can change your VPS's PHP version, memory_limit..and etc all can be done to optimize your website.
 
Shared Hosting is very similar to living in an Apartment Complex. All residents are in the same location and must share the available resources with everyone - such as the pool, parking lot, and play ground. In shared hosting, all accounts (sites) must share the available resources with all the other accounts on the server - such as CPU time, memory, and disk space.

VPS is a virtual server which is usually a part of a physical servers but has its own share of resources which are not shared by other VPS. Each VPS customer gets their own secure disk space, bandwidth, file system and process space, without sharing CPU load or applications with any other user on the VPS system.
 
Shared hosting simply cheaper hosting but have limited access to server while vps is cheaper than dedicated server but more expensive than shared hosting.
Similar to dedicated server you can have full access to your vps and you can run applications on it as per your needs.
This is not possible on shared server.
 
A VPS is always preferred as you are in complete control over your server, be it the configuration changes or installations or user level administration.
 
Shared hosting is for site that fit into 2 categories.

1) They consistently needs few resources

2) They needs large resources for short periods.

Caveats are that some people will need functionality deemed to insecure to run in a shared environment.

I have often had customers return to our shared servers, even from our managed VPSs, as they did not want to spend the money on a VPS with enough resources to run their site in a timely fashion.

Many customers return from our Unmanaged Servers, as they were unaware of the time and effort, and skill it takes to properly manage a VPS, with the newest software, security patches, performance tweaks etc.

If you choose a host shared hosting using CloudLinux, then whilst your resources are not absolutely guaranteed, there is some guarantee of performance, as each individual customer are restrained with certain resource limits (kinda like a VPS).
