Paul Nash, group product manager of Compute Engine at Google, played down the significance of the new billing model saying that Google has offered per-second billing for its Persistent Disks storage service since 2013. He said that the difference between per-minute and per-second billing is very small anyway.
“On the other hand, changing from per-hour billing to per-minute billing makes a big difference for applications – especially websites, mobile apps and data processing jobs – that get traffic spikes. The ability to scale up and down quickly could come at a significant cost if you had to pay for those machines for the full hour when you only needed them for a few minutes.”
Google said its per-second model will be available on a range of operating systems including Windows, which AWS said would be excluded from its own per-second offering.
