Study Notes
Cloud Computing Definition
- Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user.
- It relies on sharing of resources to achieve coherence and typically uses a pay-as-you-go model.
Five Essential Characteristics
- On-demand self-service: consumers can unilaterally provision computing capabilities automatically without human interaction with service providers.
- Broad network access: capabilities are available over the network and accessed through standard mechanisms, promoting use by heterogeneous thin or thick client platforms.
- Resource pooling: provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with resources dynamically assigned and reassigned according to consumer demand.
- Rapid elasticity: capabilities can be elastically provisioned and released to scale rapidly outward and inward commensurate with demand.
- Measured service: cloud systems automatically control and optimize resource use, providing transparency for both the provider and consumer.
History of Cloud Computing
- The concept of cloud computing dates back to the 1960s, with the initial concepts of time-sharing and remote job entry (RJE).
- The "data center" model, where users submitted jobs to operators to run on mainframes, was predominantly used during this era.
- The "cloud" metaphor for virtualized services dates to 1994, credited to David Hoffman, a General Magic communications specialist.
- The expression "cloud computing" became more widely known in 1996, when Compaq Computer Corporation drew up a business plan for future computing and the Internet.
- In the 2000s, the application of cloud computing began to take shape with the establishment of Amazon Web Services (AWS) in 2002.
