Cloud Native Middleware as a Programming Language
summary
Ballerina presents itself as a cloud-native language that models HTTP, gRPC and GraphQL services as first-class constructs, maps GraphQL fields to service methods and lazily fetches only requested subobjects, and exposes a strand+worker concurrency model with futures and nonblocking I/O. The toolchain compiles and generates Kubernetes artifacts and Docker images via bal build, supports Prometheus + Grafana metrics and OpenTelemetry/Jaeger traces emitted automatically, and can produce AWS Lambda packages; demos show services deployed to Kubernetes and traces/metrics visible in the dashboards.
