Architecture Styles intermediate Multiple choice
A browser-based design tool in Canva's mould lets users export a 40-page document to PDF, a 90-second animation to MP4 or a print-ready file. Export work takes anywhere from 3 seconds to 11 minutes, about 60000 a day, bursting around 09:00 in each region. All three run inside the synchronous web tier today and p99 export requests are killed by the load balancer at 60 seconds. Which architecture style should the export path use?
