2. Integration in an increasingly disaggregated world
Transactions
Circuit Breaking
Protocols
Payloads
Events
Security
Workflow
Streams
Compensation

3. AGILE
NETWORK AWARE

4. Batteries
Included
Networking
NATS
ActiveMq
WebSockets

5. Hello World

6. caller hello
GET
Hello World

7. Annotations

8. caller hello
POST (name)
Hello, name!

9. Connectors

10. caller RekService

11. Concurrency

12. Workers

13. Futures

14. Async I/O

15. This looks like a typical blocking call,
but it’s a bit more than that…
Transparent non-blocking I/O usage promotes optimal resource usage and handling of large
number of active connections

16. Stream Processing
(experimental)

17. Basic Streams

18. Filtering

19. Temporal Aggregations

20. Docker & Kubernetes

21. AWS Lambda

22. Observability

23. Distributed Tracing: Jaeger/Zipkin

24. Metrics: Prometheus + Grafana

25. Logging: ElasticSearch / Kibana / Logstash (ELK)

26. OpenAPI

27. Kubernetes Jaeger
Docker Prometheus
AWS Lambda
etcd OAuth2 / OIDC
Istio / Envoy
LinkerD RabbitMQ
Consul AMQP
Swagger/OpenAPI
MySQL gRPC / Protobuf
Postgres WebSub
Cassandra
Spring/Java
