Service Mapping

[Fares1]

Hello everybody,

I'm learning how to use Service Mapping but there's just something I can't manage to understand. 

I've installed a MID Server on my laptop and installed a Virtual Machine on which I installed Ubuntu and 2 database instances (MySQL and PostgreSQL).

I've managed to discover them all and create a Dependency view. 

However when I want to create a Service Map, I don't understand where to start. Why doesn't Service Mapping use the CI's discovered with the Discover Schedules? 

As you may notice, I have many questions.

Thank you in advance for your answers and have a great day!

 Edit : Also, what's the difference between Dependency views and Service Mapping?

Hi Fares,

Discovery : it's a horizontal Approach. meaning discovery MID server, probes and sensors collectively would ping, port ,authenticate your IPs based on the credential you have given in service now. through this you'll have Processes, softwares, file, disk, RAM, Serial number and all other components residing in your CIs.

based on the ports, processes, NIC attached etc it finds in your CIs through discovery it creates the dependency from this CI to other outbound.

Service Mapping : it's a Top-Down approach. meaning based on the ports, processes and other web based protocols discovered through horizontal discovery, service mapping tries to map your horizontal discovered components into a larger area.

for example you might have your Skype for Business Map which is load balanced and has many Web, App and DB servers and they're running on some listener services, https etc. so based on the Entry point URL you provide, Service Mp would strt the Top-Down approach from the Entry point and Map all you Skype related CIs into the Map.

IF you need to learn more, please look for Service Now service Mapping docs and few basic videos of it.

hope above helps you!. thanks...

Discovery just scratches at the surface while Service Mapping really goes as deep as it can, is that it?

hi sumeet,

Does servicenow supports skype for business by OOB? 

Thanks.

So what you're describing in your sandbox lab environment is just some stuff. Discovery will certainly build you an inventory of your stuff into the CMDB.

Service Mapping is "Top-Down" or "Vertical Slicing" or "Service Aware" version of Discovery. To map all those items, you would need some things to make them actually relate to one another. Like this:

URL <-- this is your top level Entry Point

Web Server <-- where that URL lands / resolves to

Application Server <-- attached to the Web tier through Proxy statements or Mod-Jk

Database Server <-- connected to from the App Server tier with JDBC datasource connection strings

Try getting a LAMP / WAMP stack AWS image and running Service Mapping against that.
