You want it, you search it... got it! Starting-up a web business A tale of stepping to Cloud Computing

Initial considerations Idea to provide self updating information documents, contacts, urls, bookmarks Solution an internet service which always returns the address where you can find the latest version of a given info. API (WSDL) available to create new applications Architecture Need to avoid “success disaster”-“slashdotting” and other great news

The team: different feelings Sys admins love Hardware Time & Money: problems for every founder

Why we moved to the cloud Cost Capex elimination No doubts about overspending / under-provisioning Pay as you growth model Time No HW to choose, order, install, configure and mantain! Few minutes to get a new server up and running Always run the same app on the same HW Focus on core business Use shared solutions (firewall, monitoring…) Reduce the time to market

Our Cloud Infrastructure as a service: Amazon Cloud EC2 Apache2, Tomcat, Axis2/Rampart, Terracotta, MemCached, MySQL S3 DB backups and other configurations data EBS DB hot data Managing the Cloud: RightScale Useful list of server templates & scripts Multi deployment (I love it) Monitoring & Alerts Auto Scale Our “single point of configuration”
