Cloud Computing - Overview Cloud Computing is a collection of network hosted services accessible from anywhere. The fundamental concept is to turn computing into a variable cost rather than a fixed cost by providing computational capacity on-demand from remote locations using a global network. The key characteristics of Cloud Computing are: ∙ Infrastructure remains available at all times ∙ R eliability and scalability logic remain hidden ∙ Resource usage is adjusted automatically ∙ Charges are typically consumption based The Value Proposition of Cloud Computing is: Cost Reduction (Lower infrastructure, energy, and maintenance costs) Speed to Market (Reduces time required to pilot projects) High Powered Computing (Provides “infinite” computing capacity when needed) Elasticity / Scalability (Provides on-demand capacity and high business agility) Services Delivered by Provider ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Provide Live upgrades Ensure SLAs are met Apply OS Patches Diagnose service failures Add storage capacity Handle traffic increase Respond to HW Failures Customer Concentrates on Business Logic

SaaS : Architecting Viewpoint Hardware multi tenant architecture Cust. 1 Customer 2 Customer 3 Customer n Cust. 4 Applikations & Data Operating System Multi-Tenant : Instead of collecting data from multiple data sources, with potentially different database schemas, all data for all customers is stored in a single database schema (i.e. multi-tenant). Thus, running queries across customers, mining data, and looking for trends is much simpler.
