PublicCloudsThe Cloud from Developers'Perspective

Cloud??? WTF?!?4

Computer Located OUtside of Data Center

WTF?

Cloud forDevelopers?What is Cloud?Cloud multiple hardware machines combine computing power and resourcesShare them between multiple applicationsTo save costs and use resources more efficientlyPublic cloudsProvide computing resources on demandPublicly in InternetPaid or free of charge (to some limit)Azure, Amazon AWS, Google App Engine, AppHarbor, Rackspace, Heroku,

NoSQL databases and MapReduceNew platforms and technologiesNew deployment modelThe cloud still supports your existing skillsKnown technologies, e.g. ASP.NET and WCFYour favorite programming languagesLike C#, Java and PHPRelational databases and SQL8

Cloud ArchitectureThe typical cloud architecture is multi-tier, SOA, highly-scalable and highly-available

At each tier different managed services, technologies and languages can run9MonitoringAdministrationData-basesStorage ServicesBack-End ServicesOther ServicesLoad BalancerComputing NodeComputing NodeComputing NodeCloud Architecture (2)Computing NodesHost and run your applicationsDifferent languages and frameworksE.g.
