ServiceNow Integration App

ServiceNow provides cloud-based services that automate enterprise IT operations. ServiceNow specializes in IT service management (ITSM) applications and provides forms-based workflow application development. It supports third-party application and data integrations. The most common integrations are for configuration management, incident management, problem management, change management, user administration, and single sign-on authentication.

The Chef Automate Integration App for ServiceNow, also called the Integration App, integrates Chef Automate with ServiceNow. This app is a ServiceNow-certified scoped application available from the ServiceNow store. It integrates existing Chef Automate infrastructure and compliance functionality with ServiceNow enterprise services. Once installed and configured, this integration enables Chef Automate to create and update a ServiceNow Configuration Management Database (CMDB) with data from nodes managed by Chef Automate. Chef Automate aggregates information about infrastructure nodes, the Chef Infra Client runs, and Chef Compliance scans, helping you monitor your infrastructure in real time.

The Integration App works by exposing the REST API endpoints for communication between Chef Automate and ServiceNow. Chef Automate sends HTTPS JSON data feeds to the app in ServiceNow to create and update the ServiceNow CMDB, client run, and compliance report tables.
