Ballerina is a cloud-native programming language that supports transactions, circuit breaking, protocols, payloads, events, security, workflows, streams, compensation, and concurrency. It promotes optimal resource usage and handling of large numbers of active connections through transparent non-blocking I/O. Ballerina can be used to build services that connect to various technologies like Docker, Kubernetes, AWS Lambda, and supports observability through tools like OpenAPI, Docker, Jaeger, Kubernetes, Prometheus, and AWS Lambda.
