## What it is
Ballerina is an open-source, cloud-native programming language optimized for integration, developed by WSO2, with built-in support for JSON/XML data types, network services, and concurrency. This repository contains the language compiler and core toolchain, which can generate Docker and Kubernetes artifacts directly from source code.

## Use cases
- write microservices and API endpoints in a cloud-native language
- build integration flows connecting APIs and services
- generate Docker and Kubernetes artifacts from source code
- process JSON and XML with type-safe declarative queries
- learn a programming language designed for network services
- switch between low-code visual diagrams and pro-code editing
- handle concurrency without async complexity

## When to choose
- you are building integration, middleware, or API-driven backend services
- you want a language with native JSON/XML handling and structural typing
- you want cloud deployment artifacts generated straight from source
- you prefer sequence-diagram-based visual and textual programming

## When to avoid
- you need a general-purpose language with a large ecosystem for non-integration work
- your team relies on mainstream tooling and hiring pools like Java, Python, or Go
- you need mature third-party library coverage for domains outside integration
- you want a language with broad IDE support beyond VS Code
