Virginia)); on Google Cloud, e2-small (2 vCPU, 2 GiB, $0.0168/hour in Iowa); on Akamai, Linode 2GB (1 vCPU, 2 GiB, $0.018/hour in Newark, NJ); on Vultr, vc2-1c-2gb (1 vCPU, 2 GiB, $0.014/hour in New Jersey).

Is B1ms burstable?

Yes. B1ms shares physical CPU cores and is designed for workloads that are idle most of the time and occasionally need full CPU. Sustained high CPU use can be throttled or cost extra, so pick a general purpose size with dedicated vCPUs for steady load.
