Shared hosting is not meant for websites that use large amounts of RAM. As your website grows and you add more and more content, you will start to see a decrease in your website’s load times. As soon as this happens, it’s an indication that you are maxing out your limits. Upgrading to a VPS will enable you to scale your website without having to worry about slow load times.
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.
In fact, most webhosts will offer the same LAMP web server stack software on their managed VPS plans as their shared hosting accounts. The main difference is the level of dedicated system resource allocation, such as RAM, CPU cores, bandwidth, or storage options. VPS plans also offer far more configuration options for web server customization with the command line than shared Linux or Windows hosting plans.
Shared hosting is cheap and allows you to install any gallery platform you wish if a hosting plan meets its requirements. But be careful and study your hosting provider’s Acceptable Use Policy thoroughly. The truth is, that even if they claim unlimited storage with their plans, they don’t want you to use much of it. On the contrary, they secretly hope that you will use less and they can host many other clients on the same server. For that reason, hosting providers usually put limitations on their policies (e.g. “no more than 10 GB for images,” etc.). So don’t be convinced that you have unlimited storage without first checking your shared hosting provider's policies or you will find your account suspended someday.
Similarly, in a real dedicated server, you will pay for the entire server that is not shared with anyone else. You will get complete control over all services. Unfortunately, it is also the most expensive hosting option and needs some technical expertise to manage. It is commonly used by those who have websites with specific scenarios, most commonly extremely high traffic and tight security requirements.

Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.[3]

If you want reasonably priced server space that won't load pages at a snail's pace when a neighboring site gets a huge traffic spike, VPS is a good option for your business. We've reviewed many VPS hosting services and included the best of the bunch in this guide. You should look into a dedicated server if you want to build a website on an even stronger foundation and can afford the bill.
The current trend in Linux web server OS distributions is for extremely lightweight installation requirements and integration with containers for elastic scaling of big data applications. Rancher and CoreOS both work with Docker and Kubernetes as well as other cloud orchestration platforms like OpenStack, CloudStack, CloudFoundry, OpenShift, Mesosphere, etc. Lightweight OS installations increase the number of virtual machines that can be created on data center hardware, leading to greater efficiency in production environments.
An impressive all-around performer, this is a hosting provider with great care for the little details and outstanding support team. While the company doesn’t have the most affordable VPS plans out there, it delivers outstanding value with superior quality of service. The stellar WordPress services are just the cherry on top of lightning fast servers with unique architecture and rock-solid security.

TMDHosting services has been around since 2007 providing users with a diverse set of hosting options. They offer fast VPS solutions that include generous amounts of disk space and bandwidth with the physical servers being located in either the US, Singapore or the Netherlands. Their VPS prices are in line with what you would expect for the level of service you are getting, which includes powerful CPUs and plenty of RAM.

Dedicated: True to its name, a dedicated server is entirely yours to utilize. This is usually an option for those with a high volume of traffic or those who choose to customise their website in a specific way. However, it’s an expensive choice that might not be right for you if you’re just starting out or if your requirements aren’t too advanced. VPS offers you the same luxury of privacy and dedicated resources with a small space to rent. It offers you one piece of the whole server which is exclusively yours.
Think of a shared server as a large apartment complex, and all of the individual apartments are rented by other website owners. All of you need a place to live — just like your website’s files — but going out to buy a huge family home would be too expensive for your needs. Sharing common areas and utilities in an apartment block helps keep costs down. And the same is true for shared hosting.

Shared hosting usually works for small to medium web sites.  A shared host may be less costly, but it does not allow total control over the hosting environment.  A shared host does not permit the use of different operating systems or the installation of custom software.  It may be true many web site owners are not interested in the administration of a server and prefer leaving it to their host.  However, it is ideal if a web site owner desires more control and needs new software that is not available in a shared web hosting environment.  When looking for VPS hosting, one should look at the resources needed, the upgrade process, the application requirements and the number of accounts needed on each server to determine the appropriate amount of resources for a VPS.  The cost should be reasonable for what is offered.

Expert Overview :

InMotion Hosting is refreshingly different. Its baseline VPS-1000HA-S plan doesn't have the most eye-catching price at $27.99 per month over two years, but it's easy to see why the company asks this much. The product has a better specification – 4GB RAM, 75GB storage, 4TB bandwidth, 3 dedicated IPs – than some high-end plans from other providers, backups and a cPanel licence are included for free, and there's a 90-day money-back guarantee.
