       | So, this is not really a product except for a limited user base:
       | people writing web function. Much of cloud computing that is now
       | hosted in containers is batch work (ML training, HPC jobs) that
       | depends on a combination of dependencies, access to hardware, and
       | a complex multithreading runtime.
       | 
       | Users of Lambda have demonstrated that it can do matrix
       | multiplication at supercomputer throughput rates.
       | 
       | I wouldn't mind the post so much but it badly misreprents the
       | nature of containers in cloud computing and does so in a way that
       | makes me not want to be their customer.

       | Curious if anyone outside of CF has a success or challenge story
       | to share about Isolates. Super cool tech.

         | From the Cloudflare article:
         | 
         | > Most importantly, a single process can run hundreds or
         | thousands of Isolates, seamlessly switching between them. They
         | make it possible to run untrusted code from many different
         | customers within a single operating system process.
         | 
         | From the linked comment by a supposed fly.io engineer:
         | 
         | > Under no circumstances should CloudFlare or anyone else be
         | running multiple isolates in the same OS process. They need to
         | be sandboxed in isolated processes. Chrome sandboxes them in
         | isolated processes.
         | 
         | So I'm confused where the disconnect is here. One of them has
         | to be wrong.
