What is Cloud Computing Outsourcing infrastructure to the ‘cloud’ Renting virtual infrastructure (storage, processing-power, message-queuing etc.) Provides cost-effective horizontal scalability Puts small, medium and large enterprises on the same pedestal (better idea prevails) An evolving platform for large scale web-based applications

Outsourcing infrastructure to the ‘cloud’

Renting virtual infrastructure (storage, processing-power, message-queuing etc.)

Provides cost-effective horizontal scalability

Puts small, medium and large enterprises on the same pedestal (better idea prevails)

An evolving platform for large scale web-based applications

Business Scenario: E-Business A small internet startup, providing specialized products to a targeted audience Peak-load only during specific times of year (New-year, Thanks-giving etc.) Investing hugely in infrastructure would restrict implementation of free-flowing business ideas Marginal capacity utilization of extra infrastructure at non peak-load times would be too low to justify corresponding cost

A small internet startup, providing specialized products to a targeted audience

Peak-load only during specific times of year (New-year, Thanks-giving etc.)

Investing hugely in infrastructure would restrict implementation of free-flowing business ideas

Marginal capacity utilization of extra infrastructure at non peak-load times would be too low to justify corresponding cost

Business Scenario: Batch Processing A medium level enterprise specialized in internationalization and localization business, providing high-quality automated translation-services Needs to batch process a sizable number of input artifacts in a limited amount of time Translation process is costly in terms of raw processing-power, memory and interim storage requirements For individual proposals, raising the bar of horizontal scalability is not viable

Risks & Challenges Outages happen! Reliable connection required, preferably with high bandwidth Amazon has most data-centers in US and Europe Legal angle Service Level Agreements not in place for most services Termination of an account is at the sole discretion of Amazon Data security and privacy An AWS developer has to ensure the secure storage of data Business-domain dictates specialized infrastructure requirements Lack of timely support
