It's an interesting paper, but they've made some weird trade offs regarding latency for resource efficiency that make it seem niche especially for FaaS tech, and the TPS they're hitting is surprisingly low for something that is supposedly in widespread use at their company. Some of their suggestions at the end are also already features for FaaS products in some form or another too. I think this paper is awesome and this platform is not a trivial piece of engineering to be clear, but it doesn't seem particularly novel or even reaching close to the larger workloads that public cloud services offer. >the vast majority of software companies will never count a trillion of anything As others have noted, it's not impossible that many of our own laptops have run a "trillion functions".. the devil is in the details here for systems researchers and engineers, and based on the details XFaaS isn't nearly as novel as say Presto was.
