Ballerina: Cloud Native Programming Language
0 likes104 views
The document discusses the increasing demand for integration in a disaggregated computing environment, emphasizing the role of Ballerina, a programming language designed for agile integration of microservices and various endpoints. It highlights key features of Ballerina, such as its sequence diagrammatic syntax, type safety, and support for cloud-native builds, alongside its ecosystem and compatibility with industry standards. The document also offers resources for learning and contributing to Ballerina's open-source project.
Ballerina: Cloud Native Programming Language
- 1. July 2018
- 2. Increasing demand is causing disaggregation
- 3. Everything is An Endpoint Functions APIs Data SaaS apps Legacy apps Devices Disaggregation leads to more endpoints
- 4. Integration in an increasingly disaggregated world Transactions Circuit Breaking Protocols Payloads Events Security Workflow Streams Compensation
- 5. The Integration Gap ESB, BPM, EAI Java / Spring JavaScript / Node
- 6. The Integration Gap - XPath for content access - No data typing - No compile time checks - Complex dev/test lifecycle - Decouples integration and runtime - Code + config across many files - Syntax is not integration-centric - 3rd party build and packaging
- 8. Ballerina is a compiled, type safe, concurrent programming language.
- 9. Sequence Diagrammatic Syntax and effective coding model forces developers into best practices for interaction semantics with programs displayed as a sequence diagram of its flow. Network Type System Structural types with primitive, record, object, tuple and union types with heterogeneous data handling and explicit nulls. Worker Concurrency Parallel-first concurrency model with lightweight workers that communicate with message passing and non-blocking policies. Shared Package & Cloud-Aware Build Native module versioning, dependency management, and centralized registry with target-aware build for cloud-native environments.
