What is Cloud?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, …

Cloud Computing Cloud Computing ModelsModelsInfrastructure as a Service (IaaS)

Virtual machines in the cloud on demand Users install the OS and software they

needPlatform as a Service (PaaS)

Platform, services and APIs for developers E.g. .NET + ASP.NET + WCF + SQL Azure Java + JBoss + JSF + JPA + MongoDB JavaScript + Node.js + MongoDB +

RabbitMQ

Software as a Service (SaaS) Hosted application on demand (e.g.

WordPress or SugarCRM) 7

Cloud for Cloud for DevelopersDevelopersMoving to the cloud will require new skills

New paradigms and APIs E.g. NoSQL databases and MapReduce

New platforms and technologies New deployment model

The cloud still supports your existing skills Known technologies, e.g. ASP.NET and

WCF Your favorite programming languages

Like C#, Java and PHP Relational databases and SQL

Cloud ArchitectureCloud Architecture

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

At each tier different managed services, technologies and languages can run
