Advanced High Availability Architecture

Every organization, regardless of size, relies upon access to IT and business data and services. In many cases, this accessibility is critical to the continued operation and success of the enterprise.

ServiceNow’s data centers and cloud‑based infrastructure have been designed to be highly available. All servers and network devices have redundant components and multiple network paths to avoid single points of failure. Through ServiceNow’s unique, multi‑instance architecture, Advanced High Availability meets and exceeds stringent requirements surrounding data sovereignty, availability and performance.

This white paper provides:

  • An overview of the ServiceNow Advanced High Availability (AHA) architecture
