Cloud web hosting is chosen because of the manageable nature of the resources provided because this puts the client at the heart of the hosting service, as they will have full control over how much they spend on their web hosting service. The architecture of the cloud is designed to provide large amounts of resources in one place so that as many clients can be hosted in a single environment as possible, eve though the number hosted will have relatively little impact on the cloud as a whole if a good percentage of resources are left free for redundancy purposes; where more resources are offered, this allows the cost of individual resources to be shared across more clients which will in-turn reduce the cost of individual resource units. The shared cloud is offered by most web hosting companies as the option for small businesses and individuals looking to take advantage of the cloud without any large outlays; the resources and features offered by the shared cloud have been designed with lower usage in mind. Larger enterprises that have their own dedicated servers and on-site servers to migrate will be more willing to take advantage of private cloud offerings, with the resources available here being considerably greater than in the private cloud – full control of the private cloud will also be available because it is important for business’s to be able to tailor their entire hosting product to meet their requirements.
Affordability of the Public Cloud
With the public cloud you can choose the precise resource allocations that you receive and can increase them in small increments in order to achieve the perfect virtual machine(s) for your needs. Shared cloud hosting puts you in complete control of your web hosting service so that you can set yourself a budget and stick to it, rather than having to go with pre-defined plans that can either provide you with something that is below your expectations or make you go over budget to achieve what you are looking for, but even then you have the potential to be left with excess resources that you have no particular use for. Under most circumstances it can be easy to make sure that your shared cloud virtual machines remain reliable because you can a cap on the amount spent on resources each month, guaranteeing that your budget will never be exceeded. The shared cloud can also offer a choice between Windows and Linux so that for once you are able to utilise both operating systems on the same platform.
Affordability of the Private Cloud
Running multiple dedicated servers or servers on-site can be costly because as well as taking up physical space, each server is going to be consuming large amounts of power both directly and indirectly (i.e. through network hardware and air conditioning systems). Where these servers are of a relatively low specification, migration to a private cloud can prove to be a cost-effective solution because it means that a single high-specification dedicated server can be used to provide the same services that had previously been offered by multiple physical servers. Savings are achieved through lower power consumption because of the reduced number of servers and by taking servers out of your office or off your site and placing them into a professional environment designed for server hosting that can provide the right kind of support for your hardware.
Expansion of the Cloud
In either case, you can expand your virtual machines with just a few clicks so that you have a scalable hosting environment that can be adapted to respond to the demand placed on it within seconds without causing even a second of downtime as all changes are applied instantly. With the public cloud there will always be a certain level of resources that are left free for redundancy purposes and so that existing virtual machines can be expanded – any good shared cloud configuration will place this figure at 45% of the overall resource capacity of the cloud and when you’re talking about servers with up to 96GB RAM and dual hexacore processors, that is a considerable amount of spare capacity. You can introduce new hardware to your private cloud as your needs insist as well with extra servers creating new capacity.
