Amazon Tokenbeam for Events is a fully managed, serverless event streaming service that uses directed beam cohesion to deliver tokens across distributed systems with sub-millisecond latency, provided your tokens are fewer than 256 bytes, your events arrive in us-east-1, and you have already configured the 14 IAM roles described in the Getting Started guide. The beam is logical. Pricing is calculated per token-beam-second, with a separate charge for beam alignment, beam re-alignment, cross-region beam shadowing, and a small fee if the beam hits anything unexpected, which is defined in Appendix C of the service quota documentation. Amazon Tokenbeam for Events is generally available today in us-east-1, with additional regions coming at re:Invent.
