Azure Service Bus Integration with Dynamics CE

https://ecellorscrm.files.wordpress.com/2022/04/linkedin-personal.png

Hi Folks,

In this post, we’ll talk about Azure Service bus.

Overview:

To start with Service Bus is fully managed messaging service which is used to connect any applications, devices, and services running in the cloud to any other applications or services. In this we can have queues which helps in the one directional communication and topics which provides two directional communication with the help of publish subscribe model.

Service bus can serve the following purposes

  1. Used for messaging
  2. For Decoupling producer and consumer of the message
  3. Load balancing
  4. For 1:N(publish and subscribe model) using Topics

Queues and Topics follow FIFO mechanism.

That said, lets see in action…

Create an Azure service bus namespace in Azure like below…

Following this, once you have created a namespace which is actually a container for all messaging components (queues and topics).

Next step is to create a queue or topic, in this case I am creating a queue….creating topic will be similar.

Fill up the details as required for the queue setup in the highlighted section…

After creating a queue or topic, you need to create an access policy for the same as below

Do note the queue URL as highlighted above….access control in service bus is achieved through Shared Access policies.

Once you have Primary connection string created, you need to go back to your Plugin registration tool and register a service end point for triggering your service bus message and provide the connection string in the below areas highlighted and click on next.

Next below appears for your review..

You can provide SAS Key or SAS Token for authentication in order to retrieve the messages from service bus and click on save. Now your end point is configured, now you can go ahead and create a step which will trigger the message to service bus from Dynamics, do note that you can only register an asynchronous operation inorder to communicate with your service bus.

You can perform the necessary operation and you can find the message being created in the service bus. If it didn’t show up immediately, please refresh and try after a few mins.

In order to consume these messages, you can use a console application for the sake of retrieval. Once the message is retrieved, it will be deleted from the queue by default.

Incase you want to use those messages for your troubleshooting purposes, you can peek command, the Peek operation on a queue or a subscription returns at most the requested number of messages. The following table shows the types of messages that are returned by the Peek operation.

Type of messagesIncluded?
Active messagesYes
Dead-lettered messagesNo
Locked messagesYes
Expired messagesMay be (before they are dead-lettered)
Scheduled messagesYes for queues. No for subscriptions

I hope this provides right insights for integrating service bus with Azure and service bus is widely used when both systems were not in sync and available at the same time.

Thank you for reading…
