Service Mapping on Azure PAAS application

[anand9]

I am implementing Service Mapping for few sets of application services. Few of applications are deployed on Azure PAAS, and we do have Azure cloud discovery running.

I have the entry point URL, but I don't know the underlying host. If I ask application team, they also don't know the underlying host machine for the URL of applications hosted on Azure PAAS.

Without host name, we wouldn't be able to run the service mapping.

I have gone through this doc page where it says service mapping works for Azure PAAS as well, but I fail to understand how it works:- https://docs.servicenow.com/en-US/bundle/utah-it-operations-management/page/product/service-mapping/...

All the explanation for service account, discovery on cloud, etc seems relevant to Cloud Discovery. What I fail to understand how Service Mapping discover relevant infrastructure if entry point URL is provided - These URLs don't have host names in it.

Question:- Is running Service mapping for application hosted on PAAS is same as running on IAAS or on premises infrastructure? Isn't there any cloud management API which provides the mapping between Application URL and underlying host machine, so it helps service mapping to run smoothly? How do you get underlying host name PAAS web app URL?

Thanks

when inquiring about paas entities in cloud, usually underlying resource /infra details are not relevant  and not easily obtainable. for paas and cloud discovery in general, please go with tag-based service mapping approach. it uses tags assigned to resources for the service mapping.

Hello Ram, Thanks for replying. That was my understanding that for PAAS's infrastructure are not discoverable. I was under impression that cloud discovery is for discovery of IAAS and not PAAS.

I am fine with Tag based mapping, however the document link has explicitly mentioned mentioned about PAAS's application mapping using patterns. So it is not the question of "difficulty", its a question of "possibility". If it is possible, then how PAAS's application mapping works? if not, then why document says it is possible?

in certain circumstances the underlying infra is exposed, but i would not consider this as the norm. so i request you to raise a doc issue using the thumbs down icon on the page and provide your feedback.

for simple and quick results, please use tag based service mapping.

also cloud discovery includes both infra and paas. check out all the patterns we have for paas - it is documented.

Hello Ram, thank you for replying. I provided the feedback on doc page.

I am checking the patterns for Azure in ServiceNow, but there is no clear indication which is IAAS and PAAS.

From document page, I could see following details, not sure which one is related to IAAS or PAAS!

• Microsoft Azure Application Gateway discovery
  Microsoft Azure Cloud components discovery using patterns
  Microsoft Azure Inventory discovery
  Microsoft Azure Functions discovery
