Q & A
Origin of the term “Cloud Computing”
“Comes from the early days of the Internet where we drew the network as a cloud… we didn’t care where the messages went… the cloud hid it from us” – Kevin Marks, Google
First cloud around networking (TCP/IP abstraction)
Second cloud around documents (WWW data abstraction)
The emerging cloud combines the infrastructure complexities of servers, applications, data, and heterogeneous platforms
Summarized History
1960 - John McCarthy opined that "computation may someday be organized as a public utility"
Early 1990s – The term “cloud” comes into commercial use referring to large networks and the advancement of the Internet.
1999 – Salesforce.com is established, providing an “on demand” SaaS (Software as a Service).
2001 – IBM details the SaaS concept in their “Autonomic Computing Manifesto”
2005 – Amazon provides access to their excess capacity on a utility computing and storage basis
2007 – Google, IBM, various Universities embark on a large scale cloud computing research project
2008 – Gartner says cloud computing will “shape the relationship among consumers of IT services, those who use IT services and those who sell them”
Definition
Lots of confusion
Several different “loosely applied” definitions
a style of computing in which massively scalable IT-related capabilities are provided "as a service" using Internet technologies to multiple external customers
an internal or external “cloud enabled” service offering
the provision of dynamically scalable and often virtualized resources as a service over the Internet.
a general term for anything that involves delivering hosted services over the Internet.
