Cloud Hosting is using virtual servers to host your data. These virtual servers get their computing power from physical servers. The benefit of this is that, with connectivity, you can access your data from anywhere and as much as you need to. This leads to cost saving as with cloud hosting you only pay for what you use.
I’ve heard about the public and private cloud…
There are two types of cloud hosting. You get the public and the private cloud. The majority of those that use cloud hosting use the public cloud. This cloud gets its resources from publicly shared servers. These public clouds include security measures to ensure your data is kept private.
The private cloud is used when security and privacy are of utmost importance. These clouds are powered by servers on site or with a cloud provider.
And these acronyms like PaaS and IaaS?
Cloud hosting, for example, is the alternative to hosting your website on a single server in your storeroom. If that server goes down, your website is down. However, with cloud hosting you are using multiple servers, if one goes down, your website is still up. Cloud Hosting can be delivered to a client in one of two ways, IaaS (Infrastructure as a Service) and PaaS (Platform as a Service).
PaaS is when the client is provided with software, such as CloudWare, where they can access applications and install hardware straight from the cloud. This is easier to use and more suitable for people that are less technical.
IaaS is for experienced IT professionals. The client is provided with the hardware required to access their cloud hosting. This is used when a client has a complex IT infrastructure.
But I am sure I can still do this with a physical server?
You could, but if that server goes down, your business goes down. The cloud is reliable due to getting space from a network of many physical servers. If one goes down, you don’t.
Instead of spending thousands on a physical server, cloud hosting has a “pay for what you use” model. It may spike when you utilize a lot, but you won’t pay for the same amount of utilization when it’s not in use.
A server has a limited amount of data capacity on it, the cloud doesn’t. If you need to use more cloud space you can do so with the press of a button.
Also, due to the cloud being a network of physical servers, you benefit from the advanced security of these servers.
