Azure Web Slots
Azure Web Sites has recently added support for the WebSocket protocol. Both.NET developers and node.js developers can now enable and use WebSockets in their applications. There is a new option on a web site’s Configuration tab to enable WebSockets support for an application. Azure Websites recently added support for multiple deployment 'slots' like Dev, Test, Staging. Daria Grigoriu shows Scott how this works and we look at scenarios where slot&hellip. Change deployment slots for a web app. One or more resource IDs (space-delimited).

With this years Azure Advent Calendar I made some site improvements and also upgraded the site from .Net 2.2 to 3.0, the code built and ran locally just fine, I push it to production and boom! – sites down, not good for a number of reasons.
The take away from this is I knew better, I tried to push some changes which in hindsight could easy have broken the site and by running it locally I thought its all good, the site has no tests as its content only.
By upgrading the site and attempting to add in Azure Application configuration I ran into some nuget package issues which I though I had resolved.

Azure Function App Slots
Azure has a thing called Azure Deployment Slots for Web apps and with this feature we can have the following: –
- Have 2 copies of the site running at the same time (one prod, one staging)
- Deploy new features to Staging ad then test (however you test)
- If all is good you switch slots so that the new version is now the prod version and the old prod version is switched into the staging version – if anything is borked then switch back and your back to good.

That’s the short version of what deployment slots are used for, I encourage you to take a look at them and I have this now setup for the azure advent calendar and wont be so careless next time.
