Created using API Gateway The functions are invoked from the browser using Amazon API Gateway. To setup the api gateway, create the api, and then, create a resource (path) /tickets and /booking

AWS SQS can also be used as pub sub for sending out notifications such as email confirmations for the booking

Setup an AWS API Gateway with SQS integration, configure SQS's batch size to be consumed by lambdas with provisioned concurrency. Send a message to SQS when reserving ticket, and another lambda to process the messages in the queue. This lambda will call the confirm booking or the cancel booking.
