Bridging the Gap: Hybrid Cloud - blurring the lines between public and private cloud capabilities
Posted Tuesday, May 24 2016 at 17:51
- The public cloud is often seen as something that sits outside the enterprise. But its capabilities can be brought in-house.
The benefits of cloud are now widely known; a faster time to market, streamlined processes and flexible infrastructure costs.
The public cloud model also provides rapid access to business applications or shared physical infrastructure owned and operated by a third party.
It is quick to provision, and the utility billing model employed in a public cloud means companies only pay for the services they use. And, with costs spread across a number of users, costs are kept under control.
This works especially well for certain business applications that support HR, Sales, Marketing and Support. It is also ideal for training, development and testing – where there are sporadic bursts of activity.
Private cloud, on the other hand, offers a bespoke infrastructure dedicated to an individual business, either run on-premises or hosted within a data center run by the cloud provider.
This provides most of the benefits of the cloud - an agile, scalable and efficient cloud infrastructure – but with greater levels of control and security for the business than is offered by the public cloud, and as a result, often has a slightly higher level of cost.
A private cloud is often perceived to offer the best option for mission critical applications, or those that demand a higher level of customisation – something that can be more difficult to achieve in a public cloud environment.
It can also reduce latency issues, as services are accessed over internal networks rather than the internet.
Bearing these factors in mind, a private cloud tends to work well for large and complex applications or organisations and those with stricter obligations around data and regulation.
Historically, customers have been faced with the dilemma of which model to use – public or private. They’ve had to make a decision, one application at a time.
This is mainly because public and private have had very different setups. There has not been an ability to seamlessly pick up workloads and move them back and forth between the private and public cloud.
Each ‘burst’ or ‘cross-over’ from on-premise to on-cloud (or vice versa) requires different provisioning code, security profiles, network configurations, testing and automation tools. It’s just too difficult!
Fortunately, when considering the move to cloud, it doesn’t have to be an either/or decision anymore: hybrid cloud enables companies to utilise a mixture of both, and is giving organizations new strategic options.
It is about providing the exact same infrastructure, security policies and toolsets, and, at the very last stage, choosing a deployment option – either on-premise or on-cloud.
One of the key benefits of operating a hybrid cloud is that it enables users to move applications and workloads between environments depending on demand, business needs and other variables.
