We all have heard the term ‘Cloud’ and ‘Cloud Hosting’ but how much do we know about it? We know that it’s a ground breaking technology and have heard a lot of talk about it, but are we aware of the nitty-gritties of Cloud Hosting? This article gives you a basic understanding about Cloud Hosting and how it works.
What is Cloud Hosting?
The primary unit of Cloud Hosting is the ‘Cloud’. The Cloud is simply a cluster of servers, interlinked with each other and that work together to form a single large and very powerful server via a process called server virtualization. When it comes to understanding what Cloud Hosting is, it is simply put forth by the principle of ‘Divide and rule’. This this means is that all the resources needed to run and host a website are divided and distributed across multiple servers on the cloud. This helps to avoid a single point of physical failure and makes the overall hosting a lot more reliable.
How Cloud Hosting Works
In Cloud Hosting, you have the option of a Public Cloud or a Private Cloud. The public Cloud is similar to Shared Hosting in concept where the collection of networked machines holds the data for several sites. The hardware is shared between other virtualized accounts, and so the cost of the resource is shared.
Private Cloud Hosting on the other hand, is a setup that does not share its infrastructure with any other sites. This obviously comes at a higher cost, but offers greater security and control.
Advantages of Cloud Hosting
- Reliability: As all the resources are distributed across multiple servers there is never a single point of failure. In case one server goes down, the Cloud automatically offloads the tasks on other servers in the pool, thus mitigating threat of hardware failures leading to website downtime.
- Scalability: Since you have a pool of server resources all interconnected with each other, adding and removing resources is fairly easy. This is especially good for sites that need resources to be scaled instantaneously like news sites or even eCommerce websites during sale period.
- Lower Cost: Since the resources are pooled, it becomes more affordable for everyone to pay for them. Hence Cloud Hosting is comparatively cheaper, taking into account its performance specifications. Moreover, you have the option to pay for what you use which can help you keep your hosting bills in check.
- Load Balancing: At times if the server is loaded with requests and the resources fall short, the website loading speed goes down. Also, there are chances of downtime because of lack resources or storage space. This is managed well because the Cloud scales as per the load. In case the allocated virtual resources for a website prove to be inadequate, the system automatically balances the load by gathering more resources from the cluster of servers.
Well, there you have it. Hopefully by now you must have gained a better understand of Cloud Hosting and how it works and what kind of advantages it brings to the table.
