Platform as a Service

Deploying to the cloud

What is PaaS

• Complete application stack• Pay only for what you use• Elastic scaling• No server setup or maintenance

No vendor lock-in

• Builds standard .NET based project types• No AppHarbor specific code• Easily migrate apps

Deployment

GitHub integration

Mercurial, SVN and TFS

• Build API

Maintenance manager

Continuous Integration

• Only deploys “default” branches

Service hooks

• TweetHarbor• Hook API

Application servers

• Most common frameworks and libraries are installed.

• .NET 2.0 and 4.0• ASP.NET MVC 1, 2 and 3• F#• WCF services

Add-ons

Databases and caching

E-mail

• Use SMTP4Dev locally

Logging and Performance

Designing for the cloud

• Keep in mind that:– Apps are deployed to multiple instances– Can be moved to other servers at any time

Design implications

• Don’t use local storage• Don’t use instance session state• Self-contained app packages (bin-deploy)

Scaling

Release management
