Microsoft Azure Backend / API Integration

Former Member — Tue, 18 Jul 2017 08:28:50 GMT

Hi Team,

I am exploring about integration of Microsoft Azure with SAP using backend service or API management so that we can extract data from Azure and we can use that in our application in SAP Cloud.

Could you please give me more details?

Thanks & Regards,

Praveen

Hi Praveen,

Can you provide some more details on what you are looking for? Depending on what you are trying to accomplish the solution will be different.

For example, if you have data that will live on Azure but is exposed via HTTP, that you simply want to call OnDemand into an SAP CP App you can use SAP API Management to call out to that data and bring it into the return stream to the app.

If you want to move data from Azure into SAP CP datastore to live there, or if the data is not easily accessible, you would be better off using SAP CP Integration and set up a flow to move data as needed.

Elijah

Hi Praveen,

Well, if your only aim is to have a simple API call to Azure in UI5, and you do not need to worry about credentials or endpoint discovery you might want to follow this UI5 API Call guide:

https://www.sap.com/developer/tutorials/sapui5-create-api-destination.html
https://www.sap.com/developer/tutorials/sapui5-insert-rest-api.html

And simply have the API in this case be the Blob API endpoint in question. Your app will call the API to return the data you want in this manner.

Now this is good for a simple scenario, but if you want a more advanced usage (now or in future), e.g. if you have concerns about having your app directly exposing the API endpoint and/or handling credentialing, you can do the same as above, but with API Management in the middle. That is to say, your SAP UI5 App would call API Management endpoint, to mask the underlying call. There are a number of ways to do this, you could even simply create an API Proxy in SAP API Management on the Blob API, and have the app call this API separately, but what I believe you are trying to do is a simple all-in-one call, where when your app makes a request to an endpoint, it is also enhances the response with data from Azure Blob. For this I would recommend Service Callout policy

https://help.sap.com/viewer/66d066d903c2473f81ec33acfe2ccdb4/Cloud/en-US/6b4087345716471ebc83369f5fddd9c8.html

At the end you achieve something like this

A single SAP Cloud Platform endpoint for your App, with multiple underlying pieces unseen. Or some variation like this. Hope this helps.

Elijah

Hi elijah.martinez,

I am looking for some help on uploading / download files on Microsoft Azure Blob storage using Shared Access Signature / REST API of Azure to do it in secure way in SAP UI5 application.

I don't want to use SAP Cloud Connector / SAP Cloud Platform.

If you have any idea about it please share your thoughts.

Thanks & Regards,

Praveen
