Scalable Umbraco CMS solution for Azure Web Apps

Posted on 16 november, 2015

Program Manager, Azure App Service

Umbraco CMS is a popular .NET solution to bring quickly to market dynamic web applications using ASP.NET framework. Umbraco CMS earlier versions didn’t really support auto-scaling with Azure Web Apps but the latest 7.3 version release has improvements to support better load balancing when running the application on multiple instances and support auto-scaling with Azure Web Apps. Check out this session from Codegarden for more details.

Azure quick start template gallery has ready to use ARM template that will deploy a scalable Umbraco CMS application. Here’s what this template contains:

  • Session state: This template creates an Azure Redis cache resource and pre-configures Umbraco CMS web app to use this newly created redis cache for session state caching.
  • Media folder: Umbraco CMS stores all the media content on the file server by default and on Azure Web Apps the files are stored on a shared drive used by all instances running your web app. As I/O calls increase in your web app, the performance of the app degrades as well. Since media content is static, you can serve them faster by storing them on separate server which in turn will  boost the website loading times. Azure blob storage is perfect solution for your static content. The implementation of a provider for Umbraco using blob storage is available here. This package creates an Azure storage resource and pre-configures Umbraco CMS to use that storage for all your app’s media content.
  • Load balancing across multiple instances: Umbraco CMS (version <7.3) uses Examine (Lucence engine wrapper) for indexing the site content. This can cause many issues with load balancing when running your app on multiple instances and locks on Lucene indexes. With Umbraco 7.3 used by the package below, this issue has been resolved. Setting up a load balanced environment is reasonably easy to achieve and can be done with only a few configuration file changes, as mentioned here, for configuration using Cloud based auto-scale appliances. In order to use flexible load balancing of Umbraco , you MUST
    • Setup 2 x Azure Web Apps - one for the master (administrative) environment and another for your front-end environment
    • Setup 1 x SQL server that is shared with these 2 web apps.
