Apache Camel has been the Swiss knife of integrating heterogeneous systems for more than a decade. Claus Ibsen explains how Camel adapts to the newest changes with microservices and cloud computing! Apache Camel integrations written on top of Quarkus start in a matter of milliseconds and consume just a few tens of megabytes of RAM. We will explain the technology and show a demo including the famous Quarkus dev mode. Then you will learn how the outstanding integration capabilities of Apache Camel enrich the serverless architectures based on Knative and CamelK!

21. Camel
Quarkus

22. Camel Quarkus brings together the
awesome integration capabilities of
Apache Camel and its vast component
library to the Supersonic, Subatomic
Quarkus runtime

27. Apache Camel and Quarkus runs extremely fast in JVM mode.
Startup is 1.4s (Camel 0.1s), 27mb uber-jar, and 165mb RSS memory used.
Compiled with JDK 11.0.7 on Mac OSX

28. Apache Camel and Quarkus runs blazingly fast with Native compiled mode.
Startup is 28 msec (Camel 5 msec), 54mb binary file, and 31mb RSS memory used.
Compiled natively with GraalVM CE 20.3.1 with JDK 11.0.10 on Mac OSX

29. Demo

32. Camel K

33. A lightweight integration platform
based on Apache Camel,
born on Kubernetes, with serverless
superpowers providing Cloud Native
Integration capabilities straight from the
heart of Kubernetes

34. Microservices architecture
helps decoupling business
domains, but does not
helps with coupling with
the platform

36. Demo

38. Kamelets

39. Kamelets are Kamel route snippets that
allow any user to consume complex
actions such as interacting with external
systems or executing a set of instructions
with a simplified interface, hiding all the
low level details.

43. Demo

44. Low level, Camel programmer

47. Demo

49. The Kamelet and KameletBinding are good for tooling and UIs as
they are discoverable Kubernetes resources with full
documentation.
