What is Public Cloud Hosting and How Does it Work?

Once you have decided to opt for Cloud Hosting for your website, you need to choose between a public, private, or hybrid cloud. A private cloud resides in your local data center or intranet and offers a highly secure environment to host your website. On the other hand, a Public Cloud Hosting Service is a more popular form of cloud hosting and is a great fit for most websites. In this article, we will look at Public Cloud hosting services and the way they work.Public Cloud Hosting

In Public Cloud Hosting, your website is hosted on a cluster of virtual servers providing a scalable and reliable hosting environment. Each virtual server is isolated from the others and has resources dedicated to it. This sounds similar to Shared Hosting with the difference being that websites don’t share physical resources of the web server. Virtualization creates layers which separate the resources required by the virtual servers.

Advantages of Public Cloud Hosting

Public Cloud Hosting services offer a wide range of benefits making it a preferred choice for most websites. Here is a quick look at some of them:

Resource and Cost Scalability

Since the websites are hosted on a cluster of virtual servers, resource scalability is instant and infinite. If the website experiences a spike in traffic, then you can increase the resources in no time. This also ensures that you don’t have to pay for resources that you don’t use. You can start your hosting plan with minimal resources and increase them as your site grows.


One of the biggest problems of hosting your website on a single web server is that there is a single point of failure. Therefore, if one server crashes, then another virtual server steps in immediately ensuring that the performance of your website is not affected and the users experience no downtime. This makes Public Cloud Hosting a more reliable service.

Disadvantages of Public Cloud Hosting

All hosting types have certain disadvantages too. A website hosted on Private Cloud Hosting is more secure than that hosted on public Cloud Hosting. Also, since the website data is spread across multiple server environments, most websites with critical data prefer private Cloud Hosting services. Most websites who receive high traffic prefer dedicated servers since they are easily manageable and offer more control.

Which websites should opt for Public Cloud Hosting services?

Choose Public Cloud Hosting services if:

  • Your website experiences unpredictable traffic
  • You don’t deal with critical or sensitive information
  • You prefer the on-demand cost-scalability

Summing Up

As specified above, a public Cloud Hosting service is sufficient to meet the requirements of most websites. Before you opt for one ensure that you assess the requirements of your website well.
