ENTERPRISE CLOUD, PUBLIC CLOUD, CARRIER CLOUD
Cloud computing technology brings an unprecedented level of independence and liberation in deploying applications. Applications are no longer tied to dedicated hardware, yet clouds vary significantly in their capabilities and their cost. This paper helps readers understand the differences between enterprise clouds and public clouds, and explains the advances available in carrier clouds.

THE CLOUD DECLARATION OF INDEPENDENCE
Cloud computing is galvanizing the information and communication industry. Enterprises expect dramatically lower cost and higher agility in their IT operations. Communication service providers (CSPs) are looking for new cloud-based architectures that allow them to become a new type…
CLOUDS CREATED DIFFERENT
The Declaration of Independence states that “all men are created equal”, but not so for clouds. Clouds are created different to support a spectrum of applications with very different characteristics and architectures. Applications require different levels of availability and response…
PUBLIC CLOUDS
The massive public clouds (from the likes of Amazon Web Services and Rackspace) have been highly publicized. Google has been reported to be running 900,000 servers as of 2011. Public cloud users can spin up hundreds of virtual machines within minutes to match demand spikes…
ENTERPRISE CLOUDS
These clouds address a different market than public clouds. The focus here is on new or legacy applications with special architectural, performance, availability, and security requirements. To consolidate enterprise IT infrastructures, cloud solutions are needed that can support…
CARRIER CLOUD
According to the same study, better performance is the top demand to improve adoption of the cloud. Current public clouds are highly centralized and users access their cloud resources via the Internet. This results in unpredictable network latencies. Public cloud providers have recognized the need…
