Zillow Group houses a portfolio of the largest and most vibrant real estate and home‑related brands on mobile and web. Zillow's IT team invested in a gamut of monitoring tools for their data center such as Nagios and Zabbix. Before ServiceNow, when a monitoring solution detected an event that needed attention, it would send an email to the Tier 1 IT operations team who would then use Outlook to manage the resolution of the issue. As the company grew and the team began to integrate a number of acquisitions, this process became unmanageable. With ServiceNow as a single system of record, Zillow has created a normalized view of events across their data center and various monitoring systems. Managing and resolving issues is quicker and more accurate.
