Cloud Service Mapping vs Discovery

Mason Angus · ‎01-30-2020

So I am questioning the practical differences between on prem and cloud discovery and how service mapping mixes up into this. Does cloud discovery provide additional information that regular discovery could not, for instance what applications run on given hosts? In a way a type of service mapping... And with service mapping for the cloud, is this a different module than regular service mapping, and if so, what are the differences between it and regular service mapping? Apologies for the broad questions but the documentation I found online was not very helpful IMO. Thanks in advance.

Hi - Cloud Discovery gets the AWS/Azure/etc ecosystem -- VPCs, data centers, regions, images, etc. But it does not discover the details of a running server (running processes, what IPs are talking to where, details running with the OS while VM is running, etc.). For this piece, traditional IP-based discovery (same as on-prem) is used. The 2 perspectives of IT (cloud metadata and vm details via IP disco) are then merged by the platform to provide a holistic view of infrastructure in the cloud.

Service Mapping (SM) is fundamentally the same, regardless of on-prem or cloud -- SM needs to know the infrastructure (which was collected by Disco and placed inside the CMDB), regardless of where the infrastructure resides. There is no such thing as service mapping targeted just for the cloud or on prem -- SM is simply a product that facilitates the build-out of services, into a service-aware CMDB.

Hope this helps?
