Top-Down Service Mapping

[abhijee]

Hello Team,

I have a Top-Down Service Mapping requirement for an OpenText application hosted on AWS IaaS (Infrastructure as a Service). Based on my basic understanding, to get started we would need the application entry point and the required credentials/access.

Apart from that, I would like to understand what other information or prerequisites we should request from the client before starting the Service Mapping implementation.

For example, should we ask the client for:

Application entry point/URL Application servers and hostnames AWS account/VPC/subnet details Load balancer details Database and other backend dependencies Application ports and protocols AWS tags used to identify the OpenText application Application architecture/dependency diagram Any external integrations or dependencies Also, since the application is hosted on AWS, can we use Tag-Based Service Mapping along with Pattern-Based Discovery, if feasible?

If anyone has real-world experience implementing Service Mapping for an application like OpenText hosted on AWS, I would really appreciate your guidance on the recommended approach.

I’m new to Top-Down Service Mapping, so any practical guidance on where to start, what client information to collect, what needs to be discovered, and how to combine tag-based mapping with pattern-based discovery would be very helpful.

Thank you in advance!

Hi  @abhijee ,

I would recommend to gather as much data as possible form the client. A basic or even detailed Architecture diagram might really help. 
Tag based SM will be surely helpful but for that we need to have the tags properly populated in CMDB. MAke sure the cloud discovery for AWS is bringing up most of the required Infra which the Infra team is suspecting to see in the Application service. Once you have the infra and tags, proceed with tag based SM. Make sure not to overpopulate tags which might create unnecessary dependencies. But generally speaking tag based SM are less accurate than pattern based ones, tag-0based are really helpful though, when we have limited data

I would encourage you to go through this doc before choosing one: Map application services using tags with classic Service Mapping • Australia IT Operations Managemen...
