The Hermes Messaging Service enables you to integrate your Apache Kafka environment with your ServiceNow® instance. The Hermes Messaging Service was enhanced and updated in the Vancouver release.

Hermes Messaging Service highlights for the Vancouver release

  • Publish events from your ServiceNow instance to your Apache Kafka environment and consume high volumes of Apache Kafka events from your external systems with low latency.
  • Effectively process spikes and bursts in message volume from external systems to minimize performance impacts on your instance.
  • Manage the health and performance of message delivery using Hermes diagnostic tools.

See Hermes Messaging Service for more information.
