What does a cloud-native integration scenario with Azure look like?

February 18, 2022

Refactoring your current on-premise solutions using BizTalk Server into cloud-native ones can mean a hefty investment depending on the number of solutions and size of the server infrastructure. However, if you leverage Microsoft Cloud (Exchange, Dynamics, Office365), you can achieve quite some costs savings. However, migration can still be a challenge, and the devil is in the details! Looking at integration capabilities in Azure you have the option of leveraging Logic Apps, Service Bus, Event Grid, and API Management (integration services). The capabilities these services offer can be enough for your integration needs.

A cloud-native integration scenario in practice

To illustrate what native cloud integration means let’s use the following scenario, where we leverage Logic Apps, API Management, Event Grid, and Azure Functions. MyFamilyPictures is a fictitious company offering a service for families to upload images to create an online page of family pictures. This company runs entirely in the cloud, and their architecture is shown in the diagram below.


API Management instance provides the quality of service attributes for the APIs like security (authorisation), rate limiting, and Cross-Origin Resource Sharing (CORS).

The customer interacts with the APIs through API Management – in case he/she uploads family pictures, likes to see the images, or has to pay for the service. The Store API manages the storage of the images into a blob container, which leads to emitting events via Event Grid to various functions (event handlers) – these functions download the image and push them to Image Analysis, resizing pictures, and store them eventually in Cosmos DB collection.

The Change Feed implementation monitors the image collection in Cosmos DB, once the image is stored and has all the meta-data, and resized images, an operation on the billing collection in another Cosmos DB instance will be done. Once all the processing is done, and the images are available for a customer a notification including the prices for the service will be sent via a Logic App to the customer. This architecture shows a full cloud (native) integration of various Azure Services.
