A hybrid cloud combines a public cloud and a private cloud and allows data and applications to be shared between them. It means that organisations can scale their IT infrastructure and benefit from the flexibility and power of the public cloud, without compromising sensitive data and systems that they want to keep on premises.
Public cloud + private cloud = hybrid cloud
Here’s a quick reminder of the difference between a public cloud and a private cloud:
Public cloud: this is a cloud computing service offered by 3rd party providers like Microsoft using the public internet to provide organisations and individuals with access to a variety of services. Office 356 is a great example of a public cloud based SaaS where users can set up their own profiles and accounts so they can use different applications like email, calendars, Skype, document management etc., from any device, wherever they are.
For businesses the public cloud can save money, removing expensive outlays on cost of purchase, and management and maintenance costs. It also provides them with access to the latest technology and negates the issue of legacy IT infrastructure, hardware and applications. As a scalable solution, organisations only pay for what they need, switching on and off services as required, adding or removing users as the business grows or contracts.
Private cloud: this is a computing service offered via a private internal network or over the internet, but is hosted on premises. Organisations enjoy many of the benefits of the public cloud with the addition of a customisable solution that can be designed specifically for the business. Private clouds are inherently more secure (provided the right security measures are in place) and therefore suitable for running mission critical systems and processing sensitive data. The responsibility for managing and maintaining the private cloud falls to the organisation’s IT team – not a 3rd party provider.
Both Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) can be delivered through the private cloud.
When to use the hybrid cloud
Here are three examples of when your organisation may need to use the hybrid cloud:
#1. For low risk day-to-day activities. The business uses the private cloud for sensitive activities like financial reporting, but uses the public cloud to handle high volume, low security risk web-based email or similar.
#2: Cloud bursting to handle spikes in demand, for example if the business sees seasonal spikes such as Christmas shopping, and needs additional computing power and resource.
#3: As a failover platform. Instead of maintaining an un-used infrastructure stack for business continuity, the same resource can be hosted in the public cloud for a fraction of the cost.
