  • Overview of ESB at Azilen Tech Meetup

    1. 1. Enterprise Service Bus @azilentech #AzilenTechMeetup
    2. 2. Background Information – Key to Success but challenges. Distributed data across different systems Inter organization data dependency Intra organization data dependency
    3. 3. EIP-Enterprise Integration Pattern • This data dependency needs to be resolved • We need a way to make these systems talk to each other • And the HERO is EIP • EIP-”EIP is a set of re-usable design patterns or solutions which can be used to connect more than two enterprise applications and made them talk to each other and communicate to each other.” • P2P, File Transfer, Messaging, RPC, Shared DB etc. are an example of EIPs. • P2P is the most widely used EIP.
    4. 4. P2P-Point To Point Integration • Two applications talk to each other directly, no intermediary. • P2P integration is only suitable for very few integration points and there is no possibility for future expansion. • If there are at least three different integration end-points, and many more are on the road map, then P2P integration is certainly not an option. • It increases complexity, maintenance and reduces agility and visibility.
    5. 5. What is an ESB ? “An enterprise service bus (ESB) is a software architecture model used for designing and implementing communication between mutually interacting software applications in a service-oriented architecture (SOA).” -Wikipedia • In nutshell- The enterprise service bus (ESB) is a software infrastructure or architectural pattern that facilitates application integration. • ESB provides implementations of EIPs and abstracts away all the integration complexity of enterprise application integration
    6. 6. Why do we need ESB ? • Business applications are rarely live in isolation. • Users expect instant access to all business functions an enterprise can offer, which requires different applications to talk to each other. • Fragmented application development languages space
    7. 7. Fragmented Protocol Space • Fragmented protocol space applications uses to communicate
    8. 8. Here it is!
    9. 9. Advantages of ESB ESB facilitate two or more applications talking to each other via well defined interface. To abstract away complexity (Languages / Protocols) Increased Visibility Provides loose coupling and flexibility Provides reliability, Agility, high productivity Well defined architecture Easy to on board new systems and integrations
    10. 10. Advantages of ESB Easier to migrate legacy systems Scalable/ Manageable/ stateless No matter which technologies you have to use, you always do it the same way, i.e. same syntax, same API, same automatic tests. The only difference is the configuration of each endpoint
    11. 11. Disadvantages of ESB • Lots of initial overhead • Expertise needs to be built into DevOps teams • Not for everybody (some initial understanding or development experience required) • Initial learning curve • A new technology and system needs to be maintain
    12. 12. Secondary duties of ESB • Monitor and control routing of message exchange between services • Resolve contention between communicating service components • Cater for commodity services like event handling, data transformation and mapping, message and event queuing and sequencing, security or exception handling, protocol conversion and enforcing proper quality of communication service
    13. 13. Capabilities of ESB Service Invocation Routing Messaging Complex Event Processing Mediation QoS Management Agnosticism
    14. 14. Capabilities of ESB Security Transformation (xml, csv, json) Enrichment Validation Split and Merge
    15. 15. Different ESB Frameworks • There are many different ESB offerings available in both commercial and Open Source license agreement. • The widely used open source offerings are as below 1. Apache Camel 2. Mule ESB 3. JBoss Fuse 4. WSO2 ESB 5. Spring Integration
    16. 16. Follows Same Religion
    17. 17. Comparison Criteria
    18. 18. Similarities • All these frameworks have many similarities. • All implement the EIPs and offer a consistent model • The only difference is the configuration of each endpoint • Though each framework uses different names, the idea is the same. • For instance, “Camel routes“ are equivalent to “Mule flows“, “Camel components“ are called “adapters“ in Spring Integration.
    19. 19. Differences • Very few differences between them • Community support • Tooling • DSL (Domain specific languages) • Popularity • Developer Vs. Designer centric
    20. 20. What to Focus on?
    21. 21. Who uses ESB ?
    22. 22. Million-Dollar Question –When to ESB ?
    23. 23. Wrong Usage
    24. 24. Proper Usage
    25. 25. Please Beware ! • There is no silver bullet, an ESB can also be the wrong choice. • Selecting the right product is essential for your project success.
    26. 26. Case Study-MyCart • Order management • Bulk Order management • Shipping Logistics • Customer management • Analytics (Roadmap) • Marketing Campaign (Roadmap)
