How much does it cost to run a service?
Services bill on two tiers: a base rate for keeping instances warm, plus an active rate while they're processing requests. The default size (0.25 vCPU, 0.5 GB) is $10.04/month per instance plus $0.05 per active hour; sizes go up to 2 vCPU / 4 GB at $80.30/month plus $0.40 per active hour. Builds are billed separately — $0.50 for a standard build, $2.00 when automatic configuration detection runs.
New accounts get a $20 welcome credit, which covers the default configuration for just under two months.
