The pricing is disappointing. I'm surprised Cloudflare has not tried to compete on price against AWS lately after a good start with R2. Queues, database storage, database writes, worker invocation all more expensive than the AWS offering.
I said worker/lambda invocation, $0.30/m cloudflare vs $0.20/m for lambda.
Total cost depends on async work and memory needs. Cloudflare is $20/m seconds, lambda is $1.66/m seconds, both at 128MB. lambda isn't giving you a full core, if you need CPU it is also $20/m.
