Public cloud vs private cloud

When it comes to the cloud, the options are seemingly endless. But it’s crucial that you choose the right solution for your business needs, whether that’s public cloud, private cloud, or a hybrid solution. 

Today we’re taking a look at the differences between public and private cloud to give you an idea about what could work for your business.

Private cloud

Private cloud gives organisations a dedicated cloud environment, on hardware specifically built for that organisation’s requirements - with no shared resources. Essentially, an organisation has the cloud to themselves, which can bring the additional levels of security and data privacy which are required by some governing bodies. It can be best suited to businesses that are unable to utilise shared cloud resources due to security or compliance regulations such as finance, legal or healthcare for example.

Access to private cloud environments is limited, meaning that they bring an additional layer of security compared to public clouds. Private cloud can also bring increased flexibility and better resilience. Some more traditional line of business applications may not be supported in a public cloud environment, and research and development work for example, is also often best suited to a private cloud environment.

Public cloud

With public cloud, compute services and infrastructures are shared between a number of organisations. Each customer’s data and applications remain hidden and segregated from other customers, but overall network resource is shared. Customer data is completely segregated for security. Some examples of public cloud solutions that you might be familiar with are Microsoft 365, Gmail and Dropbox.

Public cloud also comes with some great advantages. There is no maintenance - that’s provided by your service provider (although the same can be said of some private cloud environments - depending on the set ups and requirements), you only pay for what you use (you’re essentially renting your services) and you get high levels of security which are usually unobtainable to many SMEs with an on-premise infrastructure. 

But what most businesses find, is that a hybrid of these two approaches works best for them. This is hybrid cloud. Whilst Office 365 might be a suitable way of running comms and file sharing, businesses may have a particular line of business application or database which needs to sit in a private environment for reasons of compliance, functionality, or support.
