"Cloudbursting" FOR OPERATIONAL AND TACTICAL EMPLOYMENT

Cloudburst (negative): The failure of a cloud computing environment due to the inability to handle a spike in demand.Reference:"The only way to do cloud computing efficiently is to share the cloud -to establish a broad, multitenant grid (or a number of them) that balances the loads of many different companies. Otherwise, it'll be one cloudburst after another, and a whole lot of underutilized capital assets." Source: Nicholas Carr: Intuit's cloudburst frustrates customers.

Cloudburst (positive): The dynamic deployment of a software application that runs on internal organizational compute resources to a public cloud to address a spike in demand.Reference: "ISV virtual appliances should underpin a new surge in cloud use followed by self-service mechanisms and enterprise connectors enabling organizations to 'cloudburst' to using cloud services."

Reference "In addition to direct sales to enterprises, going forward it hopes that extending out from private clouds to public ones – what we like to call 'cloudbursting' – will become a prevailing IT weather pattern and provide it with additional opportunities.

As per Geva Perry

Marry the traditional safe enterprise computing model with cloud computing; in essence, bursting into the cloud when necessary or using the cloud when additional compute resources are required temporarily.

Traditionally been applied to resource allocation and automated provisioning/de-provisioning of resources, historically focused on bandwidth. Today, in the cloud, it is being applied to resources such as servers, application servers, application delivery systems, and other infrastructure required to provide on-demand computing environments that expand and contract as necessary, without manual intervention.

The hybrid application deployment model involving cloud computing requires additional intelligence on the part of the application delivery network. The application delivery network must be able to understand what is being requested and where it resides; it must be able to intelligently route requests. This, too, is a fundamental attribute of cloud computing infrastructure: intelligence. When distributing an application across multiple locations, whether local servers or remote data centers or "in the cloud", it becomes necessary for a controlling node to properly route those requests based on application data.

Connectivity requirements

Flexibility

Data duplication

Positives Concerns

Cost savings realized by organizations that take advantage of cloudbursting instead of building their own infrastructure.

Can also be an efficient method of assisting with scaling rapid growth sites at which the rate of traffic growth is outpacing the ability of IT to obtain, prepare and deploy infrastructure.

Can also be extended as a disaster recovery plan in order to reduce the costs associated with building out and maintaining a secondary, idle data center.

You must have the application deployed and available inside the cloud. It may be possible to deploy applications on-demand to the cloud computing provider, but most providers will likely require the application be deployed before it is needed.

You must have a global load balancer capable of deciding when to direct requests to a secondary site.

You must have a way to determine when your application infrastructure is near capacity. An application delivery controller (intelligent load balancer) is the most efficient mechanism for making this determination.

How do you do it?

Well understood technically with many enabling products available

Excellent option for

• Surge requirements

• Seasonal requirements

• Research & development

• Ad-hoc computing networks

Capability worth exploring
