Public Cloud Platforms
Overview, IaaS, SaaS, PaaS
www.devreach.com
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 model
www.devreach.com
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)
www.devreach.com
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, WordPress.com, …

Typical Cloud Architecture
 The typical cloud architecture is multi-tier,
SOA, highly-scalable and highly-available
Computing
Node
Databases

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

Typical Cloud Architecture (2)
 Computing Nodes
 Host and run your applications
 Different languages and frameworks
 E.g. C# + ASP.NET MVC or PHP + Symfony

Public .NET Clouds
Develop and Run .NET Apps in the Cloud
www.devreach.com
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?
www.devreach.com
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 balancing
www.devreach.com
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, …
