PriorityEngine is a cloud-based virtual queuing solution that manages traffic surges to prevent website outages and poor customer experiences during periods of excessive load. It throttles traffic by queuing and releasing requests based on the capacity of the backend systems. This ensures all requests are processed orderly and the backend systems are protected from being overwhelmed. PriorityEngine can be integrated using URL redirection or JavaScript and provides customizable waiting pages and queue management. It provides a drop-in solution to safely throttle heavy or unpredictable traffic loads during promotions without missing potential customers.

15. Business Case
Overflow load handler during large promotions
– Protect order system from excessive load
– Engage customers in a waiting area (push services / offers / messages to
all or a subset of users)
– Optional priority queuing for a subset of users (e.g. premium members,
high value shoppers) to move ahead faster
Load Throttling for smaller / targeted promotions
– Designate limited order processing capacity for smaller promotions
– PriorityEngine will ensure flow rate is within set limits
– Prevent targeted promotions from impacting regular / mainline bookings
– Enable marketing teams to try innovative / ambitious campaigns without
worrying about IT overheads e.g. Flash sale events (extra-low prices on
unsold inventory or select products), Campaigns for limited dates / times
(off-season, off-peak)
