What are the pricing models and considerations for using Azure Event Grid? Azure Event Grid operates on a pay-as-you-go pricing model. Pricing is based on the number of operations performed, which includes event publishing, delivery, and management API calls. The volume of events processed also factors into the pricing. Each event domain within Event Grid has its own pricing structure. Additional costs may be incurred for specific delivery options and outbound data transfer. Consider your expected event volume, operations, delivery requirements, and analyze usage patterns to optimize costs.
