The differences between Shared Hosting, VPS, Dedicated Hosting and Virtual Datacentres for Infrastructure as a Service (IaaS)


For most people, words from the above header are just meaningless conjugations of letters. Hopefully, we can help you bring some sense into this particular field. Let’s simplify this by using a simple analogy, comparing the similarities of hosting with different living arrangements and types of accommodation.


Shared Hosting (Student Accommodation)

Shared hosting can accurately be compared with student accommodation, both are affordable but sometimes problematic. The shared hosting student dorm provides inexpensive accommodation but they are noisy,  within small shared spaces you’ll often have to queue to use the bathroom or to make their morning tea. The noisy neighbour next door will cause you to lose valuable resources to sleep. The tiny living spaces means you’re confined, inhibiting your ability to grow and all that queueing will just stop anyone being able to get anything done on time, especially when you’re in a hurry.

Altogether, sharing hosting is somewhat restrictive and you may not be as productive as you need to be during your peak working hours. This arrangement is fine for someone who does not have heavy internet requirements but it simply will not suffice to some businesses people. That is when shared hosting student accommodation stops being an option.


VPS/Virtual Private Server (Small Studio Flat)

The next obvious place to live would be a comfortable studio flat. The neighbours might still be noisy and inconvenient but at least you won’t have to share their resources. You have your own room, your own bathroom and your own kitchen.

Living alongside other studio flats with like-minded working professionals, their requirements will be similar to yours. You’re now sharing a slightly larger living space within the VPS building – although you must be cautious of overcrowding. You’ll still have to queue to use the network elevator to get in and out of the building but again, this is a problem you will only have to deal with during peak hours.

Some people’s requirements will continue to grow and you’re restricted by size. Now you will have more customers family to consider in your decisions and harmoniously share your space with. As nice as your studio flat has been so far, you have no easy move to a larger environment and no control over the basic operations building maintenance. Next, you’ll have to choose whether to buy a dedicated server house or move to a more scalable VPS living environment.


Dedicated Server (House)

Having purchased a house (dedicated server) you are now able to make all the changes in network décor and facilities that suit your needs best, and without permission from the landlord (the provider – who has now been removed from the picture).

This is a sound, reliable option until you outgrow the environment or disaster strikes and you can no longer work without your wireless, water or electricity. Repairs could take a long time for your providers to repair it and there is no easy move during this downtime period.


Clustered VPS With Multiple Resources (Hotel Complex)

Hotel guests might encounter inconsiderate neighbours but there is a certain flexibility to move from a busy server environment rooms if needed and larger/smaller rooms are usually available. Rooms are also available in adjacent buildings if there are any issues. The desk is fitted to the wall and the features are fairly restrictive and standardised but you will still be able to access the resources and facilities available as you need them.

If you need an additional room, you may be able to get an adjoining room which is attached to yours via a network co-joining door but only with some extensive planning. In general, you’ll find yourselves having to run up and down busy corridors to pass data towels across to the other rooms.


IaaS, Virtual Datacentre (Penthouse)

The virtual datacentre (vDC), let’s call it the penthouse, is high up at the top of the building, providing the best views (best of all you’re near the clouds). Your space is absolutely private and uncontended and you are the sole controller of your own space. The features are entirely flexible and can be changed as you see fit. For example, your firewalls can be knocked down and rearranged. From floor to ceiling, The large windows are safe whilst allowing full visibility of your surroundings.

The rooms on the floor below your penthouse are reserved. Your concierge greets you, from your private elevator, securing the premises offering any assistance and friendly advice where it is needed.

The rooftop resource pool and open bar are all yours and can host as many users summer parties as you would like. The rooftop space can also be built upon to expand your living space if required as you have already been granted permission. Generally, virtual datacentre penthouse dwellers will have more than one residence in multiple cities across the world.



To conclude, “Cloud” and housing are not too different. There are different types of housing and there are different types of cloud services. Each type of house will meet the needs of different individuals and from a business perspective, cloud it is exactly the same. Different types of cloud will work for different businesses.
