Cloud Computing Summit

Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.

Four fundamental requirements for Cloud are: (1) Scale out (2) Automated service (3) High availability and (4) Multi tenancy.

Recent days, Industry started contributing towards cloud application. If you go thro netflix site (, you can feel the performance of Cloud. Last week, had a chance to attend the summit on Cloud & SOA at Bangalore. Event linked is posted at

In case of Microsoft, they are named as (1) IAAS(Infrastructure As A Service) like ForeFront, SystemCentre (2) PAAS(Platform As A Service) like SQL Azure, App Fabric, Azure OS (3) SAAS(Software As A Service) Office Live, Exchange Live, SharePoint Live, CRM Live.
