Federated Cloud Computing | What is a Federated Cloud?

Updated on May 30, 2012

How Federated Cloud Computing Solves Major Cloud Computing Problems

Today cloud computing has become the most important and fastest growing technology in IT. Now, Federated cloud computing have made the growth even more faster. It's very interesting to learn how this happened. As an emerging technology cloud computing was (and is still) experiencing several new experimentations and tweaking. Few of the major stumbling block for cloud services was the question of physical security of the data stored in public clouds, the flexibility of public clouds to be modeled according to the specific needs of an organization and the difficulty to unify the different cloud services used in a single organization. Hybrid cloud computing was the new solution that effectively solved all these issues. Federated cloud computing is an advanced form of hybrid cloud computing. In fact, federated cloud computing is the highest and best form of hybrid cloud computing so far.

How Federated Cloud Computing and XaaS work together

Hybrid cloud computing have the core concept of combining the power of both private and public clouds to develop the most appropriate cloud service for an enterprise and makes the services readily available in every devices anywhere as the user requies. Federated cloud take this concept a little more farther. The numerous services available in the public cloud is generally called XaaS (acronym for Everything-as-a-Service). Previously, the private cloud accessed these services one by one from the public cloud as per their requirement. There was no option to join up a few services from the public cloud and use it as a single functionality via the private cloud. Federated cloud computing solves this problem very effectively. It allows several services ( XaaS) existing in the cloud to cooperate and work together as per the user demands. This presents a lot of flexibility and plenty of new service opportunities for both the users and cloud service providers. The federated cloud will be a conglomerate of all the major service providers in the public cloud.

How Does Federated Clouds Function Effectively?

The proper functioning of federated clouds are driven by a linkage of several service layer agreements (SLAs). An SLA is a set of legally defined agreements stating the functionality offered by a provider and all the details about fetching and implementing that functionality. Such as, “Page ‘x’ will load in 5 seconds”. There will be a set of SLAs followed by every service provider with respect to the service they provide and the external service they work along with. These services will link together to act as a single component that has all the necessary functions required by the user tied up in one piece. The federated cloud is all set to take over the cloud by new delivery models that so far never existed. In the near future we could enjoy better services from major cloud computing companies like IBM, Google and Windows ties together to provide the best user experience. Now, companies can focus less on technicality and give more importance to services. One of the major impact is that this federated cloud computing would run well with the new demand for ubiquitous computing, where you need your data from anywhere on any device.
