1. 1 Enterprise Service Bus Mojtaba Akbarzadeh Nov 2015

2. Agenda 2 Service Oriented Architecture About ESB ESB Architecture and Components ESB Features EIP Enterprise Integration Pattern A little example

3. Service Oriented Architecture 3

4. 4 SOAP REST CORBA RPC RMI Database (SQL, NoSQL, Key-Value, …) Network Protocols(HTTP, FTP, TCP, POP, …) Service Protocols

5. 5 XML JSON Java serialization Apache Thrift Apache Avro Google Protocol Buffers (protobuf) JAXB Serialization formats

6. Service Call Synchronous Asynchronous Blocking and Non-blocking 6

7. Service QoS Availability Performance Reliability Scalability Integrity Security 7

8. 8 software architecture construct, which lives between the (business) applications and enables communication among them replace all direct contact with the applications on the bus reduces the number of point-to- point connections between communicating applications About ESB

9. Event handling - Guarantee event processing Protocol conversion - Transparently translate between communication protocols (e.g., HTTP, FTP, REST, SOAP, JSON, DCOM, CORBA, SAP RFC etc.) Mapping - Transfer between tabular data formats 9

10. About ESB Translation and transformation - Change data content based on rules Queuing and buffering - Handle differing data processing speeds between sender and receiver 10

15. ESB Features Connecting Anything to Anything Minimal Custom Development, Developer Friendly and Easy to Deploy Routing, Mediation & Transformation Message, Service, API & Security Gateway High Performance, High Availability, Scalability & Stability Manage & Monitor 15

16. Routing, Mediation & Transformation Routing:  header based  content based  rule-based  priority-based Enterprise Integration Patterns (EIP):  message filter, aggregator, splitter,..  recipient list  dead-letter channels  guaranteed delivery 16

17. Manage & Monitor Comprehensive management & monitoring Built-in collection and monitoring of standard access and performance statistics JMX MBeans for key metrics monitoring and management Flexible logging support with integration to enterprise logging systems Centralized configuration management 17

18. Auditing & Logging Centralized Auditing & Monitoring Capture any user action capture any user action Logging can be a very crucial aspect ESB is a distributed clustered set up where we have several applications We need to keep centralized application logs Asynchronous and None-Blocking Data publishing Receives and Stores Log Events in highly scalable and Big Data Repository Rich tool set for analytics Dashboards and reports 18

21. ESB Nodes یک ESB مجموعه ‏ ای از نودها ( کانتینرها ) است که هر نود می ‏ تواند حاوی تعدادی سرویس فعال باشد. در واقع این مجموعه از کانتینرها تشکیل یک ESB می ‏ دهند. 21

24. 24 What is Apache Camel Why do we need integration?  Your apps are build using different tech stacks  Critical for your business to integrate Why Integration Framework?  Framework do the heavy lifting  Focus on business problem  Not "reinventing the wheel"

29. 29 A little example Goals  1) Pickup files from a directory  2) Make sure we only pickup 3 files per 30 seconds  3) Store into JMS queue  4) Listen on JMS queue  5) And upload file to FTP server
