Public clouds platforms are rapidly growing and many businesses move partially or fully their IT infrastructure to the cloud. The big players like Microsoft, Google, Oracle and Amazon operate their own public cloud platforms while the smaller players provide cloud services and PaaS platforms and on top of the larger. What about the .NET developers and the cloud?

In this talk the speaker Svetlin Nakov introduces the public .NET clouds and compares the leading .NET PaaS clouds: Windows Azure, AppHarbor, Uhuru and AWS Elastic Beanstalk for .NET. The .NET public clouds are compared in terms of architecture, programming model, pricing, development stack, available services, deployment model and tools for administration and monitoring. A live demo shows how to deploy and run a typical .NET application (based on ASP.NET MVC and MS SQL Server) in AppHarbor and Uhuru.

    • Public Cloud Platforms for .NET Developers Svetlin Nakov | Sofia, 4-5 October 2012
    • Agenda Public Cloud Platforms  Typical Cloud Architecture Public .NET Cloud Platforms  Cloud Types: IaaS vs. PaaS  Windows Azure  Amazon AWS (+ Beanstalk for .NET)  AppHarbor  Uhuru Choosing a .NET
    • Public Cloud Platforms Overview, IaaS, SaaS,
    • What is Cloud? Cloud ≈ multiple hardware machines combine computing power and resources  Share them between multiple applications  To save costs and use resources efficiently Cloud for Developers?  New paradigms and APIs  E.g. NoSQL databases and MapReduce  New platforms and technologies  New deployment
    • Cloud 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 + IIS + ASP.NET + WCF + SQL Azure  JavaScript + Node.js + MongoDB + RabbitMQ  Software as a Service (SaaS)  Hosted application on demand (e.g. Bugzilla, WordPress, Sitefinity or SugarCRM)
    • Public Clouds Provide computing resources on demand  Publicly in Internet, for everyone  Paid or free of charge (to some limit)  Could be IaaS, PaaS, SaaS or mix of them Examples of public clouds  Amazon AWS, Google App Engine, Windows Azure, Rackspace, Heroku, Engineyard, AppForce, PHP Fog, AppHarbor, Uhuru, OpenShift, CloudBees, CloudSwing, Oracle Public Cloud, Salesforce,, …
    • Typical Cloud Architecture  The typical cloud architecture is multi-tier, SOA, highly-scalable and highly-available Load Balancer Administration Monitoring Computing Computing … Computing Node Node Node Data- Storage Back-End Other bases Services Services Services  At each tier different managed services, technologies and languages can
    • Typical 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, …
    • Public .NET Clouds Develop and Run .NET Apps in the
    • Public .NET Clouds I am .NET developer  I want to use a .NET cloud for my apps  What I can do? IaaS vs. PaaS approach  IaaS: VPS or cloud hosting  Rackspace / Tier3 / any hosting provider  PaaS: write your app for certain platform  Azure, AWS, AppHarbor, Uhuru, other?
    • IaaS for .NET Developers IaaS / VPS / cloud hosting  Could work well for .NET applications  Offered by hundreds of hosting providers  Full control over the production servers  Limited support:  E.g. DB server failure fix it yourself!  Difficulties to configure high-availability + load
    • PaaS for .NET Developers Two types of .NET PaaS clouds:  Microsoft Azure  Write your app against the Azure APIs  E.g. use SQL Azure, not SQL Server  Vendor lock-in  AWS, AppHarbor, Uhuru  Write your app purely in .NET  Use IIS, SQL Server, ASP.NET, WCF, …
