What is Apache Camel
● The swiss knife of integration
● 10+ years of development and one
of the most active Apache projects

● Packed with functionality
The giant Swiss knife 😅

● Java based integration framework
● Runtime support: Spring Boot, Apache Karaf / OSGi, JEE / WAR,
Microproﬁle, Quarkus, Standalone, and more ...
● Based on Enterprise Integration Patterns
● Comes with 300+ components (connectors)
● DSL (Java or XML) to describe integration ﬂow (routes)
● Can integrate everything ... almost everything
● 10+ years of development - still one of the most active Apache projects
● The cornerstone of Red Hat Fuse

System Integration

● camel-core vs camel-core-engine
camel-core
(Camel 3.x)
camel-core-engine
(Camel 3.x)
Includes 33 Camel JARs
(core & core components)
(similar to camel-core 2.x)
Includes 12 Camel JARs
(core only functionality)

Camel 3 - Optimized
● Faster startup and lower footprint
○ Smaller core & less classes loaded etc
● Optimized camel-core
○ Many smaller optimizations
examples/camel-example-console
Camel 2.x: 5179 classes loaded (5.3 mb camel JARs)
Camel 3.x: 4286 classes loaded (3.9 mb camel JARs)

Camel 3 - Optimized
● Source code generated invocation (no Java reflection)
○ Type Converters
○ Route configuration
○ Endpoint configuration
○ Component configuration
● Build & Init lifecycle phase
○ Prepare before start (eg Quarkus build time preparation)
● JMX management optional

Camel 3 - Endpoint DSL
● Endpoint DSL
○ Type Safe
○ Java Fluent Builder style

Camel 3 - Reactive
● Reactive Core
○ All EIPs now fully reactive
○ Blocking vs Non-Blocking code-paths merged into one (Non-Blocking)
● Postponed for Camel 3.x
○ Backpressure
○ Client API
○ Java 9+ Flowable API (requires to drop Java 8)

Camel 3 - Camel Main
● Standalone Camel
○ Bootstrap for Camel K & Camel Quarkus
○ Unified configuration (also for Camel Spring Boot)
● Configurable
○ application.properties (ala Spring Boot)
● Tooling Support
○ Eclipse
○ Eclipse Che
○ VSCode
○ IDEA

Camel 3 - Microprofile
● Eclipse Microprofile Integration
○ Configuration
○ Metrics
○ Health Checks
○ Fault Tolerance (in progress)
○ Reactive Messaging (3rd party)
■ https://smallrye.io/smallrye-reactive-messaging/#_integrating_with_apache_camel

Camel 3 - Other
● JUnit 5 support
○ camel-test-junit5
● Step EIP
○ Group together N+ EIPs (logical name)
○ Grouped performance statistics
● Lazy start producer
○ Avoid Camel to fail on startup if producer fails to start
(typically connecting to remote system)
● Writeable Registry
○ Easier to add your own beans
● Route Model more extensible
○ YAML route builder (Camel K)

What is serverless?
“Serverless computing refers to the concept of building and running applications
that don’t require server management. It describes a ﬁner-grained deployment
model where applications, bundled as one or more functions, are uploaded to a
platform and executed, scaled, billed in response to the exact demand needed”
https://github.com/cncf/wg-serverless
Serverless personas:
● Developer: writes code for, and beneﬁts from the serverless platform.
● Provider: manages the serverless platform.

● Provider: manages the serverless platform.

Serverless (Compute)
Here’s my personal deﬁnition of “serverless”.
Before it becomes a billing model, we need to deﬁne it “technically”.
Serverless is a programming model based on:

...
1) Auto-scaling services/functions
(including scaling to zero)

2) Event-driven execution
...
1) Auto-scaling services/functions
(including scaling to zero)

Serverless requirements
For the platform
● Scaling to zero
● Rapid scaling up and down
● Eventing mechanism
● Routing and networking
For the application runtime
● Fast startup
● Fast ﬁrst response
● Low on memory and CPU
● Small size on disk

Build
A pluggable model for
building artifacts, like jar
ﬁles, zips or containers
from source code.
Knative Overview - Components
Serving
An event-driven model
that serves the container
with your application and
can "scale to zero".
Eventing
Common infrastructure for
consuming and producing
events that will stimulate
applications.
Kubernetes-based platform to build, deploy, and manage modern serverless workloads

Characteristic Monolithic/SOA Microservies/CNA Functions/Serverless
Packaging Ear/War/Jar Fat-jar Native executable
Startup procedure XML scanning Annotation scanning Instant (ahead-of-time compilation)
Memory/binary size 1000s MBs 100s MBs 10s of MBs
Startup/ﬁrst response Minutes Seconds Milliseconds
Process lifecycle Long running Managed by platform Ephemeral (executed per request)
State (app/user) Stateful Stateless (no user state) Ephemeral (no application state)
Data ownership Shared data model Owns data No data ownership
Operations Multiple unrelated operations Multiple domain operations Single event driven operation
Scope Multiple business domains Single business domain Single task
Motivation Non-scalable, high complexity

Rapid productivity, at the expense

What is Quarkus ?
Supersonic Subatomic Java

What is Quarkus ?
Supersonic Subatomic Java
A Kubernetes Native Java stack tailored for GraalVM &
OpenJDK HotSpot, crafted from the best of breed Java libraries
and standards

Apache Camel and Quarkus runs blazingly fast with native compiled binaries.
Startup is 10 msec, 32mb binary file, and 13mb RSS memory used.

Observabilty Example
● Microproﬁle Health
● Microproﬁle Monitoring
● Random delay 1s to 5s
Jaeger UI

○ Camel K 1.0.0-M3 supports Camel 3.0.0-RC1
● Quarkus as integration runtime
○ Reduced footprint and cold start-up time
○ Native image build in parallel swapped with JVM
image during auto-scaling once ready
● Knative 1.0 → Camel K 1.0.0
● Support the Broker / Trigger model
● Support Tekton builds
● Push-based endpoints
● Fully integrated with Syndesis / Fuse Online
● Better IDE support
● Better integration with CI tools
● BDD testing
● Operator Capability Level 3+

Camel Quarkus - Roadmap
● Camel Extensions on http://code.quarkus.io
● Port more Camel components as Extensions
(22 done out of 300)
● More build time optimisations
● Reduce startup overhead
● Quarkus 1.0 → Camel Quarkus 1.0.0
● Better IDE support

Camel Kafka Connector
● A kafka connector source and sink implementation that embeds camel.
● It is conﬁgurable to use most of the camel-components.
● Making it able to talk with 300+ different kind of external systems.
300+ components!

Camel Debezium
● Stream changes from databases to Camel
● camel-debezium component in Camel 3
○ MySQL connector
○ Other databases on the way ...
