  2. The Cloud from Developers‘ Perspective Windows Azure Google App Engine (GAE) Amazon Web Services (AWS) AppHarbor Agenda Public Clouds

  3. The Cloud from Developers'Perspective

  4. Cloud??? WTF?!? Cloud forDevelopers? Computer Located OUtside of Data Center WTF?

  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, …

  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 Applicationsand Services Intel Hybrid Cloud Dell Cloud ComputingSolutions Adobe Creative Cloud CA Cloud Solutions Symantec.cloud services Salesforce Force.comCloud Computing Platform EMC Atmos CloudDelivery Platform

  7. Cloud Computing Models • Infrastructure as a Service (IaaS) • Virtual machines in the cloud on demand • Users install the OS and software they need • Platform 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)

  8. Cloud for Developers • Moving 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

  9. Cloud 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 Monitoring Load Balancer Administration Computing Node Computing Node Computing Node … Data-bases Storage Services Back-End Services Other Services

  10. Cloud Architecture (2) • Computing Nodes • Host and run your applications • Different languages and frameworks • E.g. C# + ASP.NET MVC or PHP + Symfony • Stateless by design • Databases and Storage • Relational and NoSQL databases • Blob storage, file storage, CDN • Other Services • Queues, notifications, logging, email, …

  11. WindowsAzure

Windows Azure • Microsoft Windows Azure • Fast-growing public cloud • Provides rich PaaS platform • Mainly for .NET developers • Supports all major .NET technologies • ASP.NET MVC, WCF, ADO.NET EF, WWF, … • Provides also Java, PHP and Node.js APIs • No free version, only 3 months trial • Bulgarian citizens cannot register!

  13. Azure Architecture Azure Load Balancer Visual Studio + Azure Tools Windows AzureManagement Portal Compute (Web role) Compute (Worker role) Compute (VM role) VM running IIS7 Windows VM Windows VM ASP.NET / PHP / other C# / .NET code / Java code Custom software SQL Azure Tables Blobs Queues CDN Other Azure / external services

  14. Windows Azure Services • Windows Azure Compute • Computing instances run Windows OSand applications (CPU + RAM + HDD) • Web role • Internet Information Services (IIS) machine for hosting Web applicationsand WCF services • Worker role • Long-running computations • VM role • Windows VM (non-persistent)
