Most businesses have a range of software packages they regularly use, which vary between departments. For some time, this has been the only way to make new functionality available to your staff quickly and affordably.
Over the past decade, there has been a massive change in ITSM processes, bringing centralization and unification to the forefront of every corporate IT plan. Now, legacy software and incompatibility between software packages are some of the biggest hindrances when aiming for an efficient workflow.
Thankfully, ServiceNow can help you to plan around these issues on your cloud migration journey. With time and planning, you could quickly achieve end-to-end automation using ServiceNow.
Service Mapping allows you to build a comprehensive overview of the different devices, applications, and hardware configurations on your network. All businesses can benefit from Service Mapping, thanks to its ability to uncover hidden links between various aspects of your business.
With a comprehensive analysis of both software and hardware aspects of your IT infrastructure, you can use this information to create a service-aware view of your daily IT service operations.
Asset Management solutions have existed for decades now, and Service Mapping is an evolution of this used by ServiceNow.
When a device connects to your network, its credentials will be noticed by the network asset discovery program on your server. From here, the discovery program will automatically populate its database, with information like:
With Service Mapping in ServiceNow, this process relies upon a Discovery server and a Management, Instrumentation, and Discovery (MID) server. Discovery uses both horizontal and top-down asset discovery processes, and MID allows for proper communication between the ServiceNow platform and 3rd party software.

Two main approaches exist to discover assets on a network, which are horizontal and top-down.
Horizontal discovery collects information on configuration items (CI) on your network before adding these details into your configuration management database (CMDB). This is done through a combination of Port Scanning, Classification, Identification and Exploration by the discovery server. You can trigger the discovery process in ServiceNow using ‘Quick Discovery’, or schedule it on an hourly, daily or weekly basis to suit your needs.
This method of discovery analyzes your whole network from a single point of access. From here, top-down discovery can track all the dependent services and CIs on your network from start to finish.
Top-down discovery can also be incredibly useful during a system outage. By rescanning your network, you could use top-down to find the culprit, since this discovery method follows the same path each time. The scan will fail to perform a full discovery, but you’ll see the final node it was able to analyze, meaning the next node in the list is likely the problem.
Top-down discovery does require some data before use. The primary credentials ServiceNow may need are:
