Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. Monitoring, logging, and distributed tracing are key methods that reveal the internal state of the system to provide the observability. Ballerina becomes fully observable by exposing itself via these three methods to various external systems allowing to monitor metrics such as request count and response time statistics, analyze logs, and perform distributed tracing.
Ballerina makes it easy to write microservices that integrate APIs.
A compiled, transactional, statically and strongly typed programming language with textual and graphical syntaxes. Ballerina incorporates fundamental concepts of distributed system integration and offers a type safe, concurrent environment to implement microservices.
A type system that embraces network payload variability with primitive, object, union, and tuple types.
An execution model composed of lightweight parallel worker units that are non-blocking where no function can lock an executing thread manifesting sequence concurrency.
