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.

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

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

7. AGILE
INTEGRATION SIMPLE

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.
