All You Need to Know About Hybrid Cloud

In recent times, many businesses are preferring Cloud services over their traditional counterparts for a variety of reasons. A cloud can be of two main types – Public Cloud and Private Cloud. As the name suggests, data in a public cloud is stored in the data centre of the service provider. These data centres also host data of other users. It is a shared environment with account isolation using virtualization. On the other hand, a private cloud is exclusive to you and the data resides in your own data centre or intranet. Both private and public clouds offer certain advantages to users and are recommended for specific requirements. In this article, we will look at the third type of Cloud service – Hybrid Cloud.

What is a Hybrid Cloud?

In simple words, a Hybrid Cloud is a blend of a public cloud and a private cloud. There is an encrypted connection between the clouds which allows a secured flow of data and/or information.

Features/Benefits of a Hybrid Cloud:

  • The flexibility of resources – One of the main benefits of a Hybrid Cloud is the ability to transfer processes from one cloud service to another offering resource flexibility. For example, you can choose to move processes which require more resources to the public cloud service and critical process to the private cloud.
  • Security – Since a hybrid cloud uses both private and public clouds, you can choose the cloud based on the security requirements of your applications and/or data. While private clouds offer high levels of security, good public cloud hosting providers also ensure that they offer a secure environment for your hosting needs.
  • Cost-efficiency – Since a Cloud is based on the concept of virtualization of resources, it allows you to add resources as and when you need. Therefore, your costs are limited to the resources used and you are not required to pay for backup resources. This makes it a highly cost-efficient option.

Here is a scenario to help understand Hybrid Cloud:

Let’s say that a website gets thousands of visitors every day from January to June and relatively fewer visitors during the rest of the year. This can happen due to the nature of the services/products offered by the site. Therefore, such a site needs a host who can allow it to instantly increase and decrease resources based on the traffic. Most Public Cloud Web Hosting providers offer instant resource scalability to manage such unplanned traffic spikes.

However, if the website also needs to manage critical or sensitive data, then it might not be comfortable with a public cloud set up. Such websites can opt for a Hybrid Cloud wherein they can store the sensitive data in the private cloud and manage traffic using the public cloud.

Summing Up

A Hybrid Cloud offers the combined benefits of both private and public clouds. However, you must ensure that your private cloud architecture is compatible with the public cloud involved. A Hybrid Cloud is highly customizable and you must assess your hosting requirements carefully before talking to a host before migration.
