3. The Cloud from Developers' Perspective

4. Cloud??? WTF?!? 4 C omputer L ocated OU tside of D ata Center

5. What is Cloud? Cloud ≈ multiple hardware machines combine computing power and resources   Share them between multiple applications   To save costs and use resources more efficiently Public clouds   Provide computing resources on demand   Publicly in Internet   Paid or free of charge (to some limit)   Azure, Amazon AWS, Google App Engine, AppHarbor, Rackspace, Heroku, … 5

6. Why Cloud Matters? Microsoft Azure IBM Cloud Apple iCloud Oracle Public Cloud SAP NetWeaver on Demand Google App Engine Amazon Web Services HP Cloud Services VMware Cloud Foundry The Rackspace Cloud Cisco Cloud Applications and Services Intel Hybrid Cloud Dell Cloud Computing Solutions Adobe Creative Cloud CA Cloud Solutions Symantec.cloud services Salesforce Force.com Cloud Computing Platform EMC Atmos Cloud Delivery Platform 6
