Service Mapping of Cloud Services

[Sam_Nat]

Hi,

I'm implementing Service Mapping of services which are hosted on AWS cloud, so is there any specific pre-requisites for this kind of Service Mapping?

I looked through the ServiceNow doc there is an article regarding Service Mapping of cloud services:

https://docs.servicenow.com/bundle/vancouver-it-operations-management/page/product/service-mapping/c...

Other than this article there is not specific article regarding Service Mapping of cloud services.

So, any steps or pre-requisite regarding the Service Mapping of Cloud services would be helpful.

Thanks

Hello @Sam_Nat 

Service Mapping in the cloud is notoriously more difficult than traditional on prem mapping purely due to the fact that Cloud Services such as AWS etc make a lot of use of PaaS services that are not immediately available to interrogate (AWS Lambda, for example, is not something that can be easily mapped due to access issues).  This is not so much of a problem if you are running traditional workloads on virtual servers in the cloud, as the existing patterns will still work with those resources & you can deploy a MID server accordingly to do the mapping.

I would recommend starting with a full Cloud Discovery of each of the environments you think you may need to map, to populate the CMDB accordingly (which helps in the identification of CI's during the mapping process) & give you an idea of how many PaaS resources are actually in use; I would also suggest speaking with the Application SME's in the organisation to see if and where PaaS resources are being employed.

I've performed the cloud discovery of AWS resources already which includes VM instances, images, hardware types, accounts etc. everything that is involved in AWS Cloud Discovery except for the Host/OS installed on the VM instances.

Except for this already discovered data, what else might be a pre-requisite for Service Mapping of AWS cloud services ?

Hi @Sam_Nat ,

in that case, you need to used the tag based service mapping and tag should be updated on AWS Resource.

Refer below documents, which help.

Tag based mapping is there for Service Mapping of cloud services, and about the Pattern based mapping

how helpful that is in case of Service Mapping of services hosted on cloud?
