The Differences Between the Public, Private, and Hybrid Cloud

Written by



It’s no secret that cloud computing has significantly changed the way many companies do business, but choosing the right variant of the technology isn’t always easy, especially if you aren’t familiar with the differences. Public, private, and hybrid cloud designs all come with their own benefits and drawbacks, so selecting the option that is best suited to your needs is essential. To help you make the ideal selection, here are some of the differences between public, private, and hybrid cloud.



When people imagine a cloud, they are often picturing the public version. This technology began with offerings like Software-as-a-Service (SaaS), or applications that are accessed over the internet and hosted elsewhere. Now the public cloud provides options for applications, data storage, and infrastructure, where the technology is housed with a third-party provider.


In the most basic sense, a public cloud centers on shared physical hardware, and access is provided by obtaining services from a third party. Often, this solution is ideal for small- to medium-sized businesses that may otherwise not be able to afford to invest heavily in internal IT resources, like servers and other infrastructure.



A private cloud often resembles on-premises data centers but provides you with additional options. This includes the ability to use automation, software, and virtualization to create an infrastructure that mimics the cloud, providing you with additional flexibility regarding how business gets done. While it doesn’t offer the full array of options you can get in a public cloud, it does give you the ability to exert more control over items like compliance, data privacy, and security, which can be incredibly beneficial for companies operating in highly regulated industries.


While the function resembles an on-premises data center, that doesn’t mean you have to keep your equipment onsite. Third-party vendors do provide access to private clouds, though the cost is likely to be higher than a public one. Often, you get the same level of control using a vendor as you would maintaining the hardware internally, so you should be able to implement security and compliance standards based on your needs.



Regretfully, there is no single widespread definition of what is and is not considered a hybrid cloud, but, at its core, these systems combine features of public and private clouds to maximize efficiency while maintaining certain security standards. For example, applications may be placed on a public cloud while data remains on a private one.


The intent behind a hybrid cloud design is to give you the best of both worlds, allowing you to pick and choose which data, applications, or infrastructure pieces are placed where. This is often done to balance accessibility with security and each solution can be customized to meet the needs of a specific organization.
