With the advent of cloud hosting, many businesses are looking at ways in which they can consolidate their existing dedicated hosting services into the cloud as a way of saving money and providing them with added reliability and functionality. Even thoughdedicated server hosting is a term that can be applied to VPS hosting servers and dedicated servers, cloud hosting can still act as a replacement for both forms of hosting if you choose the right package because of the ability to host a virtual environment in the cloud and because of the resources that are on tap in the cloud. Many businesses are now seeing the benefits of consolidating their existing servers and VPS servers into the cloud through the use of scalable virtual machines; as well as reduced cost and management time, cloud virtual servers are also easy to expand as and when you wish, therefore allowing you to deal with any predicted load spikes effectively to reduce the chances of performance being affected. The prices of each type of hosting plan differ greatly, with VPS servers being relatively low-cost to dedicated servers and because the specifications of dedicated servers can be scaled so greatly, dedicated servers can either be relatively cheap or very expensive; virtual environment cloud hosting plans are designed to slot right in the middle, by providing you with a high-specification dedicated environment without having to pay the price that you would associate with a dedicated hosting solution of a similar specification.
Pricing
The pricing structure of virtual machines in the cloud allows you to develop a web hosting plan based around your own specific needs as you can specify the exact specifications that you wish to see in a service, therefore meaning that you will only ever be paying for what you need and use. The cost of a VPS server can vary greatly depending on the VPS hosting plan that you choose for your needs; you should also remember that your choice of operating system (between Linux and Windows) would also impact on the price you pay for a VPS server. Dedicated servers on the other hand are relatively expensive and the multitude of hardware configurations that can be achieved mean that you can easily end up spending thousands on dedicated servers.
Uptime Guarantees
Depending on the specifications of your VPS server or dedicated server, there is a good chance that a cloud hosting plan will be able to offer you additional uptime guarantees over your existing hosting service. Unless otherwise specified, most VPS servers are hosted in a single-server configuration meaning that there is little room for failure – if the hosting node crashes then your VPS serverwill be taken down as well. Likewise, unless you choose to use multiple dedicated servers then a single-point of failure will exist in your setup as if the server crashes then anything hosted will be taken down as well.
Multiple servers are used to form a cloud environment and so the primary benefit that cloud hosting will have over dedicated hosting in general is the removal of the single point of failure. Cloud environments are designed to provide up to 100% guaranteed uptime and this is achieved by ensuring that if one server in the cloud fails, this doesn’t impact performance because there will be additional servers and slaves available to pick up the slack left.
Scalability and Flexibility
By choosing dedicated hosting in a cloud environment, you will have access to a far more scalable platform than can be offered by VPS hosting or dedicated hosting as the resources of multiple servers will be pooled in the cloud meaning that you will be able to create virtual machines with RAM, disk space and CPU resource assignments that will outweigh what you will be able to get with a VPS server or dedicated server for the same price. Depending on the web hosting provider that you choose, it should be fairly easy to upgrade the specifications of your virtual machines as and when you wish; some web hosting companies have introduced automated systems that provision the resources to the specified virtual machine the moment that you have paid for the additional resources.
Resources
Although a cloud hosting service will be able to provide you with additional resources that may not be available with VPS hosting or dedicated server hosting, you should take into consideration that a dedicated server will have the power to offer you a number of different hardware configurations that aren’t possible with virtual server hosting. With so many servers being pooled to form a cloud web hosting environment, you can easily create additional virtual machines using varying resource allocations as you require; you will also be able to add additional resources instantly. With VPS hosting and dedicated server hosting you may find that the allocation of resources isn’t instant, therefore putting cloud hosting at an advantage in this category.
Security
Dedicated hosting products and cloud web hosting products offer similar levels of security, with both designed to offer dedicated environments that can be configured to meet the user’s own specific requirements. With data being distributed throughout the cloud, it can be argued that a cloud hosting service can offer a higher level of security than a dedicated hosting product; however, there are many different security applications and services that can be used with a VPS server or dedicated server to achieve a similar level of security.
In conclusion, cloud hosting and dedicated hosting share many benefits, but your choice between cloud hosting and a VPS server or dedicated server is likely to rest on your budget as opposed to the specifications that you require from a web hosting service. Both types of hosting are able to provide you with a secure web hosting environment, therefore we would recommend either for business users; however, a cloud environment may be able to offer the additional reassurance of 100% uptime guaranteed, something that may tip the balance for many users.
