What is the hybrid cloud? And how does it benefit my business?

8 Oct 2014 by Insight Blog

Migrating to the cloud is a big decision.

Deciding between private and public cloud offerings can be just as tough – but with a hybrid cloud service you have a compromise between the two.

Hybrid cloud is making serious waves among senior IT professionals, with some 70% of organisations either using or evaluating using a hybrid cloud service, according to TechPro Research.

In this guide we’ll define the hybrid cloud and explain its main benefits.

What is the hybrid cloud?
The hybrid cloud combines public (external) and private (internal) cloud services to offer your organisation the best of on- and off-site services.

Public cloud services are available to all organisations via a subscription through third-party providers such as Microsoft and Google. Organisations pay for services as they need them – these include data storage and applications hosted in the cloud.

Private cloud services are internal, on-site solutions that are managed by your organisation’s IT department. They are generally favoured for sensitive data and large, demanding operations such as customer relationship management.

How does it work?
The public and private cloud services are separate entities. Each runs independently of each other.

However they are combined by an encrypted bridge, which means they can communicate with each other. In some cases both systems can be monitored with the same toolset.

Three benefits of the hybrid cloud
1.) The best of both worlds
Most companies have concerns about migrating their entire IT operation to the public cloud. Hybrid cloud allows you to keep your most demanding services and sensitive data – your firm’s ‘crown jewels’ – on private systems while using the public cloud for running applications.

Handling customer relationship management and enterprise resource planning through the public cloud is often deemed too much of a risk for large organisations.

With a hybrid system, vast amounts of sensitive data can be kept internal on the private cloud.

2.) On-site systems
With a hybrid set-up you will have an on-site infrastructure that is accessible directly rather than having to route it across the public web. This means organisations are not solely reliant on the public internet and also lessens latency.

3.) Ability to scale services to business demands 
At different times in the year, businesses have busy periods and quiet periods.

With hybrid you have the agility to scale services up and down accordingly – boosting business agility.

Hybrid cloud offers private in-house cloud infrastructure to cope with regular demand. Then when demand increases during your peak months, ramp up your public cloud service when computing demand exceeds that of your private cloud infrastructure.
