OwnerRez is a robust Property Management System (PMS) designed for vacation rental owners and property managers. It provides an all-in-one platform that handles various operational tasks such as booking management, guest communication, invoicing, and reporting. It has an extensive range of integrations with popular Online Travel Agencies (OTAs) like Airbnb, Booking.com, Vrbo, and others, enabling easy synchronization of bookings and calendars across multiple platforms.

Pub/Sub allows services to communicate asynchronously, with latencies on the order of 100 milliseconds. Pub/Sub is used for streaming analytics and data integration pipelines to ingest and distribute data. It's equally effective as a messaging-oriented middleware for service integration or as a queue to parallelize tasks.
