- 4. Long History behind Fuse
- 6. Integration platform Manage Complex use cases correlation, orchestration, routing, mediation, transformation Provide BUS exchange messages Designed around different specs: JBI, SCA
- 7. ESB & JBI Services & Components communicate using NMR bus Packaged as zip (=SU) in a big zip (=SA) including xml config, target service Constraint : messages formated as XML EIP not included in the spec
- 8. Apache Camel Java Integration Framework Implements Domain Specific Language Supports Enterprise Integration Patterns
- 9. Enterprise Patterns implemented and more : Loadbalancer, Throttler, Delayer, … > 50 patterns
- 11. Route, processor Camel project Collection of routes Route Processor(s) + Interceptor(s) Producing or consuming Messages/Exchanges
- 12. Interceptor To trace, log, capture business events
- 13. Convert Type Type Converter Strategy Allow to convert the body payloads from one type to another To and From these types File String byte[] and ByteBuffer InputStream and OutputStream Reader and Writer
- 14. Data Format Data Transformation for complex use case Marshalling : Object XML (JAXB) Unmarshalling : XML Object (JAXB) packagemy.cool.demo; importjava.io.InputStream; importjava.io.OutputStream; importorg.apache.camel.Exchange; publicinterfaceDataFormat{ voidmarshal(Exchangeexchange,Objectgraph,OutputStreamstream)throwsException; Objectunmarshal(Exchangeexchange,InputStreamstream)throwsException; }
- 15. Data Format supported > 20 Data Format

- 27. Container Routes/Endpoints registered CamelContext Policy Security Lifecycle Tracing JMX Threads can be configured
- 29. Communication
- 30. Facts In-Memory bus Support Object : XML, File, Stream, Bytes Predicate & Expression language (xslt, xpath, …) Sync/Async exchanges Threads Management Tx Architecture Error & Exception handling Policy driven Container Agnostic
- 31. Apache Karaf Java OSGI Runtime Offer modularity for Integration Multi-Technology platform
- 32. Architecture Technology Camel, CXF, ActiveMQ, Spring, Fabric, … Modular platform deploy or remove container/libraries
- 33. Core features SSH server Allow to administrate/create instances Provide provisioning solution features Hot deployment Configure & manage instances JAAS Security layer Role Base Access Control (RBAC)
- 34. Integration container Camel routes isolated from each other (classloader) Bundle CamelContext boundary acting as a Local BUS Camel routes can have different SLA (Threads, Policies, …)
- 35. Integration container Camel routes can be started/stopped/updated Simplify maintenance process
- 36. Integration container New routes can be hot deployed Like also "Beans/POJO, Web Services, …"
- 38. Fabric8 v1 Opensource integration project - Mission simplify management & deployment java integration services on different machines & JVMs http://fabric8.io
- 39. Features Manage container creation (locally, remotely, cloud, openshift, docker, …) Visualise what is running into JVM to understand your platform Monitor whats running and easily scaling up or down Support Upgrade via Version changes and Rollback Virtualize services (endpoints), processes Search and storage engine for logs, camel, messages, metrics
- 40. Karaf limitations Karaf can create new instances (locally) & administrate them (locally or remotely) Instances are not cloned Configurations must be managed (manually, script)
- 41. Fabric extends the possibilities
- 42. Coordinating System : Zoo Rely on Zookeeper server (ensemble of 1,3, 5 or servers) Coordinating distributed systems in a reliable way (electing leaders, implementing master/slave, sharding or federation of services).
- 43. Fabric Agents Are the clients of the Zookeeper server(s) They will communicate with Zk server to : register container info (ports, services, endpoints, processes) get their provisioning
- 44. Profiles Behavior of a container Envelope(s) containing artifacts to be deployed, parameters (system, jvm, services) to be configured Can be versioned, facilitate mngt - rollback
- 45. Virtualization & Load balancing Goal Create virtual endpoints, to scale services (WS/REST, A-MQ)
- 46. New topologies New topologies (Replicated - LevelDB storage, NPlus1), Broker discovery
- 47. Metrics Fabric Insight Technology NoSQL storage for JSon documents Based on ElasticSearch
- 48. Dashboard Kibana is the web front end Full Text Search features
- 49. Info collected Logs, Camel metrics, JMX metrics, your own data/JSON metrics importorg.apache.camel.Header; importorg.fusesource.insight.storage.StorageService; importjava.sql.Timestamp; importjava.util.Date; publicclassStoreService{ privatestaticStringES_TYPE="insight-tweet"; privatestaticStorageServicestorageService; publicstaticvoidstore(@Header("tweet-full")Stringdata){ storageService.store(ES_TYPE,generateTimeStamp(),data); }

- 53. JMX Tools JConsole, VisualVM Developers tool ( ) Proprietary comprotocol (RMI/IIOP) Command line tools jmxclient, jmxterm, mx4j Not so user friendly :
- 54. Jolokia ? Command line tools jmx4perl, j4psh JMX / HTTP Bridge REST API : read attributes, execute operations
- 55. Modern HTML5 Architecture Hawtio = A combination of the most powerful web technologies Front end : HTML5 with AngularJS & JSON / REST Backend : Java Servlet & Jolokia JMX gateway
- 56. Communication … Web client communicates to Jolokia agent over HTTP(S) Send Messages represented in JSON Format to Jolokia REST Servlet Jolokia translates the request/response & map the JSON payload with JMX Calls
- 57. Domain JMX Domain / context java.lang, com.sun.management, java.util org.apache.camel io.hawt … Attributes & operations
- 58. Plugin What is a plugin ? Collection of UI JSON request(s)/response(s) JS lib to do the rendering

- 61. Jolokia Request Javascript function called to execute a GET request of type execor read Mbean & Attributes OR Operation are passed as parameters onSuccess calls function for the rendering jolokia.request({ type:'exec', mbean:id, operation:op, arguments:null }, onSuccess($scope.onResponse,{error:$scope.onResponse}));
- 62. Jolokia Search Search operation is supported Find MBeans according to a search querybased on the type of the MBean to find A search query to find the type Connector Anoter search query for mbeans based on the type "*:j2eeType=WebModule,*" functionloadData(){ varconnectors=jolokia.search("*:type=Connector,*"); if(connectors){ varfound=false; angular.forEach(connectors,function(key,value){ varmbean=key; if(!found){ vardata=jolokia.request({type:"read",mbean:mbean,attribute:["port","scheme","protocol" ... jolokia.search("*:j2eeType=WebModule,*",onSuccess(render)); } 1 2 1 2

Plugins Plug-an-play architecture ( > 25 plugins ) UI updated in real time Some are Packaged : jvm, threads, dashboard, camel, activemq, … Some are Server side : git, maven, aether, log Some are External : insight, elasticsearch, kibana Reusable for developers (branding, datatable, forms, ide, perspective, tree, ui)
- 65. What Front looks like
- 66. Discover your camel routes
- 68. Integration & Mediation Platform > 100 components : file, jms, ftp, … > 50 EIP Patterns : content based router, splitter, aggregator, …
- 69. Messaging Broker Platform Support : JMS, AMQP, MQTT, STOMP, Websocket iPaas (Openshift cartridges - v2)
- 71. Point-to-Point Messaging Producer sends message(s) to queue using JMS API Consumer listens for message(s) from queue Messages stored until read or expired Messages can be persisted, are read only once
- 72. Load Balancing Workload can be distributed between connected clients Round-robin algorithm used
- 73. Publish and Subscribe Client sends message to topic Broker sends message to all currently connected subscribers Messages are consumed x times (1-to-many)
- 74. Durable Subscriber Messages usually expire when subscriber(s) not connected Supports connection/disconnection DurableSubscriberproperty = unique client ID registered to broker Subscriber client ID controls messages delivered to broker
- 75. Request/Reply Producer sets 2 properties to send message JMSReplyTo: Destination for response message JMSCorrelationID: Unique ID matches/correlates messages (request/response) Consumer replies to JMSReplyTodestination using JMSCorrelationIDin message
- 76. Network of Brokers Created when one broker establishes network connection to another broker: Supports multiple connectors To define as bi-directional, use duplex=true:
