  2. 2. Your hosts for today Daniel Meyer Technical Lead Jakob Freund CEO
  3. 3. Do you already use Camunda? No answer; 45; 8% Not at all; 166; 32% we're evaluating; 174; 33% we're developing; 83; 16% we're in production; 58; 11%
  4. 4. Why do you use Camunda? Reasons: •Executes BPMN 2.0 •Best option for Java •is Open Source Advantages: •Stanardized technologies and Skills •More flexible •Easier, quicker development •cost-effective Also trusted by:
  5. 5. Camunda 7.2 Statistics April 1st –Nov 30th ~ 1,700 person days Features; 209; 33% Bugs; 203; 33% Tasks; 211; 34%
  6. 6. Camunda BPM 7.2 •Performance / Scalability •Tasklist •Connectors / Data / Scripts / Templates •CMMN
  7. 7. Camunda BPM 7.2 •Performance / Scalability •Tasklist •Connectors / Data / Scripts / Templates •CMMN
  8. 8. Performance / Scalability •Camunda BPM is increasingly used in High-Load Situations •A „high-load situation“ starts at ~10 instantiated processes per Second •Some Customers run Camunda with > 1,000 Process Instances per Second •This means we continuously improve the performance and scalability •Execute process instances in a short amount of time •Support load balancing in Clusters •Prepare Camunda for alternative storage strategies (No SQL, In Memory etc.)
  9. 9. Camunda 7.1 (!) compared to JBoss jBPM 6 More Information: http://camunda.com/landing/whitepaper-camunda-jbpm In our tests, Camunda‘s throughput was 10x –30x higher than with JBoss jBPM.
  10. 10. Performance Improvements in 7.2 •Improved First Level Cache (throughput increased by up to 90%) •Improved Load Balancing for Cluster Mode •Log Level for History can be configured •Minimize Risk of Deadlocks in High-Load Situations
  11. 11. Camunda BPM 7.2 •Performance / Scalability •Tasklist •Connectors / Data / Scripts / Templates •CMMN
  12. 12. What isTasklist?
  13. 13. Tasklist 7.2 In collaboration with “The tasklist is the central point of contact for business users with the BPM platform and is therefore an essential component. The innovative implementation of the Camunda tasklist matches the DAB bank's web technology stack perfectly and saves extensive in-house development. The functionality is optimally aligned to the Camunda BPM platform and due to its flexible adaptability also fulfills the needs of a bank. Karl Brandner, Chief Architect
  14. 14. Live Demo 1 2 3
  15. 15. Technical Architecture Camunda Backend REST Camunda JavaScript Forms SDK AngularJS Twitter Bootstrap
  16. 16. Your own Setup? Camunda Backend REST Camunda JavaScript Forms SDK Your very own HTML 5 User Interface
  17. 17. Camunda JavaScript Forms SDK •Greatly simplifies the implementation of task forms. •You can directly bind Html form controls to process variables. •The Forms SDK handles the fetching of the variable values from the process engine, type conversions and so on. •The Forms SDK optionally integrates with AngularJSto take advantage of AngularJS form validation and other AngularJS goodies. More: https://github.com/camunda/camunda-bpm-sdk-js <form> <inputtype="text" cam-variable-name="CUSTOMER_ID" cam-variable-type="String"> <inputtype="text" cam-variable-name="CUSTOMER_REVENUE" cam-variable-type="Float"> </form>

  19. 19. The paradigm Developer-Friendly System Integration Death by Property Panel vs. Camunda Zero-Code BPM Suites
  20. 20. Java Objekte in XML or JSON serialisieren Camunda BPM Database Customer, Address XML or JSON Advantages: •Anyone can directly inspect Java objects in the database and Cockpit •It is easier to set up polyglot architectures (e.g. Java + Javascript)
  21. 21. Live Demo Yay!
  22. 22. Improved Handling of Data Formats XML or JSON Advantages: •Directly access XML or JSON within the process via APIs •No need to convert XML or JSON into Java Objects
  23. 23. Why Scripts and Templates are awesome •No Java Code / Classes needed •(Re-)deployment during runtime •Can be versioned as part of the process definition •Can be embedded inside the BPMN as well as referenced and maintained in standalone files •Great performance thanks to compile & cache
  24. 24. Advanced Support for Scripting
  25. 25. Advanced Support for Templates Camunda Enterprise Edition
  26. 26. Scripts and Templates in the Process In Script Tasks In Listeners As Conditions As IO- Mappings
  27. 27. Connectors
  28. 28. Connectors •Simple API for implementing Connectors as reusable Components •Included with Camunda 7.2: SOAP and REST (both based on Apache HTTP Client) •Fundamentally different approach than Zero-Code Suites: •Developer become more productive –it‘s not about „empowering Business Analysts“ •However not every developer speaks Java •Primary Target Group: IT divisions that want to provide a workflow infrastructure for their organization (other IT teams) •Focus on API instead of Properties •Connectors can be used in different components, e.g. Java Delegates
  29. 29. A powerful combination Connectors Data Scripting
  30. 30. Example: Do I have to work today? REST JSON Javascript
  31. 31. Simple REST Call Start with Process Variable date (e.g. via unit test) Invoke REST Service that provides holidays as JSON Run Javascript that checks if dateis a holiday and puts result as variable holiday: true|false Route based on holiday https://github.com/camunda/camunda-bpm-examples/tree/master/servicetask/rest-service
  32. 32. Live Demo Yay!

  34. 34. Camunda BPM 7.2 •Performance / Scalability •Tasklist •Connectors / Data / Scripts / Templates •CMMN
  35. 35. CMMN 1.0 •Published by OMG in May 2014 as the BPMN-equivalent for „Cases“ •Targets „Activities that are not so predefined and repeatable, but instead depend on evolving circumstances and ad hoc decisions by knowledge workers regarding a particular situation, a case (see Davenport 1994 and 2005; and Van der Aalst 2005)” •Typical Use Cases: •applicationandclaimprocessingininsurance •patientcareandmedicaldiagnosisinhealthcare •problemresolutionincallcenters •invoicediscrepancyhandling More: http://www.omg.org/spec/CMMN/1.0/
  36. 36. You often have both Unstructured Processes Nonroutine Work Structured Processes Routine Work
  37. 37. Camunda integrates BPMN with CMMN
  38. 38. Example: Incoming Invoices
  39. 39. „Review Invoice“ is a Case
  40. 40. CMMN: A complex example Source: OMG
  41. 41. „Review Invoice“ as a simple Case CMMN Modeler by Trisotech
  42. 42. CMMN explained Human Taskthat will be created when the Case is created Completing the Task triggers Completion of the Case Milestone, that will be reached depending on the outcome of the Task Human Task, That maybe created by the knowledge worker Process Task, that maybe created by the knowledge worker
  43. 43. Starting a Case within a Process…
  44. 44. …and starting a Process within a Case!
  45. 45. Live Demo Yay!
  46. 46. All combinations are possible •BPMN standalone •BPMN calling CMMN •CMMN calling BPMN •CMMN standalone
  47. 47. Should Istart with CMMN now?
  48. 48. Should Istart with CMMN now? Yes, cause it‘s safe with Camunda ;-)
  49. 49. Dedicated Webinars about… •Performance / Scalability •Tasklist •Connectors / Data / Scripts / Templates •CMMN Invitation coming soon!
