Clouding Computing
Cloud computing is the on-demand access to IT resources (compute, storage, and applications) through services. The key characteristics of cloud computing are on-demand, resource pooling, elasticity, broad network access, and measured services with pay as you go.
Benefits of Cloud Computing
- Trade Capital Expense for Variable Resource – Only pay what you use
- Stop guessing about capacity – Scale with the business needs
- Massive economies of scale – Supported by big Cloud providers such as AWS
- Increase speed and agility
- No need to run and maintain data centers
- Go global in minutes
