In an Azure ServiceBus you can create multiple subscriptions for one topic. Such a subscription has the possibility to filter messages. So only the messages that match the criterias are “forwarded” to the subscription. Let’s have look on how filters work.
In this post I will use the ServiceBus Explorer to connect to an existing ServiceBus namespace. If you want to know how to create a ServiceBus namespace, a topic plus subscription and connect to it with the ServiceBus explorer – then read my previous blog post about it: How to create a topic with testdata in Azure ServiceBus
In this blogpost I will describe how to create a ServiceBus and a Topic in Microsoft Azure and how to push some sample data with the ServiceBus Explorer to it. In a following post I will describe how to work with ServiceBus filters.
Before you create the servicebus, you should download the servicebus explorer tool which you can find here: https://code.msdn.microsoft.com/windowsapps/Service-Bus-Explorer-f2abca5a
When you connect to Azure, e.g. the Azure ServiceBus Explorer to the ServiceBus (https://code.msdn.microsoft.com/windowsapps/Service-Bus-Explorer-f2abca5a), you will probably deal with proxy issues. I sometimes got the following error:
An error occurred attempting to access the account:
The remote server returned an error (407): Proxy Authentication Required
