Cloud Computing: Hybrid Clouds
True that it is getting noisier with cloud computing. And in clouds, hybrid cloud is making more noise! In giving the meanings to hybrid, dictionaries mention that it is an offspring of two animals and more similar synonyms. Going further, they use the word heterogeneous in origin and composition, two different types of components doing the same function. Hybrid clouds, as we know, depict the combined use (benefits/problems) of private cloud and public cloud. Are there two different types of components in Public and Private Cloud? Are they heterogeneous in nature? Leaving these questions to geeks (and meanings of word to etymologists), let us see what hybrid cloud offers to the businesses and enterprises.
Public and Private: The clouds that we know, Amazon Web Services (AWS) EC2, RackSpace CloudServers, FileServers etc…are public clouds. A private cloud is one; either built within enterprise (internal) or may be one dedicated offering from a service provider. Usually referred as within firewall! Dedicated to one enterprise and not shared with other enterprises. These are deployment models of cloud. Underlying architecture may be same.
Hybrid: As we read now from technology blogs, the most likely scenario of future is, every enterprise may end up with a hybrid cloud, wherein they will make use of both internal cloud and public cloud, preferably in tandem, picking the one that suits to requirement. Enterprises are looking for right technology from now onwards. And so, the onus is now with the cloud service vendors to gear up their service model, architecture suitable towards hybrid model. Similarly enterprises deliberate their long term cloud strategy by keeping in mind that in future anything and everything should work in anything and everything with little or no engineering efforts.
In the future, every IT resource available in cloud globally for on demand usage will be at our disposal!
