The Ballerina Programming Language

The Ballerina programming language

Ballerina is a statically typed, open-source cloud-native programming language developed and supported by WSO2.

With Ballerina, you could easily develop microservices, API endpoints and integrations, and any other application for the cloud. Additionally, Ballerina has all the general-purpose functionalities you could expect from a modern programming language.

With Ballerina's compiler-level built-in support for widely used data types such as JSON and XML, your focus on handling structured data, network service interactions, and dealing with concurrency is made much more effective.

Providing and consuming services

It has inherently concurrent first-class language constructs for providing and consuming services.

Sequence diagrams

Sequence diagram based graphical view shows the most fundamental aspect of the semantics of a network distributed application.

Structural typing

It allows for looser coupling between distributed components and eliminates the friction of data binding.

Metadata

Extensible metadata enables easy integration of Ballerina programs with cloud platforms. You could directly generate Docker and Kubernetes artifacts straight away from the source code.
