1. Install Episerver Azure package from nuget 

2. Change blob provider 

<blob defaultProvider="azureblobs">
  <providers>
    <add name="azureblobs" type="EPiServer.Azure.Blobs.AzureBlobProvider,EPiServer.Azure"
          connectionStringName="EPiServerAzureBlobs" container="mycontainer"/>
  </providers>
</blob>

3. Add connection string 

<connectionStrings>
  <add name="EPiServerAzureBlobs" connectionString="DefaultEndpointsProtocol=https;AccountName=myaccount;AccountKey=abcdefghij" />
</connectionStrings>

You can use this even if you don't have the actual site in azure.

Hi Daniel,

Thx for fast answer!
I have installed EpiServer.Amazon package, but i still can't find <blob/> section in web.config, in some tutorials i saw that this should be in episerver.config but i don't even have episerver.config in my solution. 
Do i need to add <blob/> section on my own in web.config ?

kind regards
Nemanja

It's in web.config under the Episerver.framework element. See

Thanks, 

I'll take a look at it !
