SERVERLESS COMPUTE MANIFESTO ▸Functions are the unit of deployment and scaling. ▸No machines, VMs or containers visible in the programming model. ▸Permanent storage lives elsewhere. ▸Scales per request: User cannot over- or under-provision capacity. ▸Never pay for idle (no cold servers/containers or their costs). ▸Implicitly fault-tolerant because functions can run anywhere. ▸BYOC - Bring Your Own Code. ▸Metrics and logging are a universal Right.
