Linking OCI to ServiceNow via Oracle Integration by Michael Chen

Introduction

Oracle Integration Cloud (OIC) is often used to connect to SaaS apps such as Salesforce and ERP. In my case, that app is a ServiceNow developer instance. Common integration patterns involve sending data between SaaS apps, whether in a one-to-one or multi-pronged approach. However, it is also possible to set up integration with OCI services that emit events. This is commonly done through the use of Oracle Functions, a "serverless platform that lets developers create, run, and scale applications without managing any infrastructure." The general structure of such an approach is the following:

• Some OCI service emits an event
• An OCI Event is configured to capture this event
  • This event is linked to a function, which is triggered
• An OCI Function invokes an integration

Design Overview

Use case: manage cloud compute networks using ServiceNow tables. A customer wanted to manage the VMs that they created in various clouds using their ServiceNow account, which they were already familiar with. The idea here is that their ServiceNow tables would automatically sync with their cloud environments to reflect the state of all the VMs in their cloud networks. Here is an example: suppose I have three Oracle VMs and one GCP VM. One of the Oracle VMs is terminating, and another Oracle VM is stopped. On my ServiceNow table, called cmdb_ci_vm_instance_list, I will see four entries: one online Oracle VM, one offline Oracle VM, one terminated Oracle VM, and one online GCP VM. Now, suppose I provisioned a new GCP VM and restarted the offline Oracle VM. The ServiceNow table should automatically update to show two online Oracle VMs, one terminated Oracle VM, and two online GCP VMs. Finally, if I were to drill down into one of these entries, I would be able to view some basic information such as date of creation, VM shape/image, CPU count, etc. Read the complete article here.
