Why Care?

Operational Excellence & Elasticity • • • Usage Comp ute Average “Unpredictable Bursting” Average Usage Time “Predictable Bursting” Comp ute • “Growing Fast” “On and Off” Comp ute • Need high reliability • LOB, software as a service Need massive scale • Social networking, web 2. 0 Have variable load / unpredictable lifetime • Ticketing, marketing Parallel processing • Financial applications Don’t fit in well with a company’s data center • Avoid IT dept, support joint ventures Benefit from external storage • Archive Comp ute • Average Usage Time
