What is Hybrid Cloud?

What is Hybrid Cloud

Hybrid cloud is a mix of different cloud ‘types’ or environments. For example, it could include on-premise private clouds, externally hosted private clouds and public cloud services. It may be a mix of UK-based hosting services with global hyperscale public cloud services. Basically, it’s a hybrid mix of different clouds.

Many organisations choose a hybrid cloud solution so that they can deploy their applications and data across a range of cloud environments, to suit their individual organisation’s needs and business challenges, such as reducing cost and increasing service agility.

Some organisations have a range of applications that can’t be put into the public cloud, for commercial or data protection reasons. In this case, many deploy certain applications internally, other applications with a hosting provider in a private cloud environment, and the remaining applications with a public cloud services provider. Alternatively they may consume their apps as Software-as-a-Service (SaaS) solutions.

Some hosting providers offer hybrid cloud solutions, where your different cloud environments are brought together and managed centrally, with the ability to move data and apps between environments easily. The hosting provider takes care of connecting the different cloud environments so that everything can ‘speak to each other’ and so that workloads can be moved from one cloud environment to another.


Hybrid clouds can be useful for organisations who only need scalable public cloud environments for periods of heavy business demand – for example, in e-commerce businesses during Black Friday promotions when more server resource is needed. Businesses can use an on-premise private cloud service and move in to the public cloud when more resource is needed, without having to pay for the extra resource all year round. This helps to make in-house and private cloud environments more scalable and flexible to meet business demand.

Cloud journeys

Hybrid cloud solutions can also work if you are still on your ‘cloud journey’. You may want to eventually move all services to the public cloud, but need a more immediate way to bridge the gap between your current in-house IT and true cloud services. A hybrid cloud environment enables you to leverage the flexibility, scalability and the potential cost savings of the cloud without having to commit to moving all workloads to the cloud in one go.


For security reasons, you might feel more comfortable with segmenting your applications and data and keeping confidential data in-house or in a dedicated environment. Hybrid cloud still enables you to use cloud services for the parts of your business that suit public cloud delivery, whilst retaining the security and peace of mind of keeping data close.

Building a hybrid cloud

Hybrid cloud can form a mix of the below areas, and you can choose any one or multiple types of environment to suit your hybrid cloud needs:

In-house IT
You may choose to keep some of your IT in-house but connect it to another external cloud environment.

Physical servers and storage may be housed in an external provider’s datacentre.

Managed Hosting
A service provider may manage all or part of your physical hardware and IT systems.

Private Cloud
You may consume your services from a privately hosted cloud environment, dedicated to you or with shared infrastructure.

Public Cloud
Where shared infrastructure is delivered at scale and services can be deployed at speed.
