The document discusses cloud-native middleware as a programming language called Ballerina. Ballerina is designed to address integration needs in an increasingly disaggregated world with many endpoints. It provides a compiled, type-safe language with built-in support for concurrency, networking, and cloud-native capabilities. Ballerina aims to simplify application integration across microservices and other technologies through its integration-centric syntax and features for transactions, circuit breaking, protocols, payloads, events, security, workflows and streams.

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

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.
