Microservices - Death of the Enterprise Service Bus (ESB)? (Update 2016)

Microservices are the next step after SOA: Services implement a limited set of functions. Services are developed, deployed and scaled independently.
Continuous Integration and Continuous Delivery control deployments. This way you get shorter time to results and increased flexibility. Microservices have to be independent regarding build, deployment, data management and business domains. A solid Microservices design requires single responsibility, loose coupling and a decentralized architecture. A Microservice can to be closed or open to partners and public via APIs. This session discusses the requirements, best practices and challenges for creating a good Microservices architecture, and if this spells the end of the Enterprise Service Bus (ESB). A live demo will show how middleware and Microservices complement each other using containers, continuous integration, REST services, and open source frameworks such as Cloud Foundry.

A live demo showed a "Microservices Middleware Architecture" using Cloud Integration (with Cloud Foundry PaaS), Integration and Services (with TIBCO BusinessWorks Container Edition), API Management / Open API (with Mashery) amd Log Management / IT Operations Analytics (ITOA, with Papertrail and LogLogic / Unity).

20. 20 Enterprise Service Bus (ESB) An enterprise service bus (ESB) is a so#ware architecture model used for designing and implemen3ng communica3on between mutually interac3ng soSware applica3ons in a service- oriented architecture (SOA). Its primary use is in enterprise applica3on integra3on (EAI) of heterogeneous and complex landscapes. h@p://en.wikipedia.org/wiki/Enterprise_service_bus (Wikipedia, 2016) “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.

24. 24 Definition of the Term “ESB” in 2016 •  Do not care about branding •  What is a “modern” ESB? –  flexible, distributed, scalable infrastructure –  build, deploy and monitor any kind of (micro)services in an agile, efficient way with open standards –  Development and deployment can be done on-premise, in the cloud, or in a hybrid approach –  Be aware of re-branded central EAI brokers with old code base and new name. Watch out for API-only platforms, which re-implement ESB features. •  What to use an ESB for? –  Integration, orchestration, routing, (some kinds of) event processing / correlation / business activity monitoring –  API and REST are great. However, have you ever used a mature and powerful SAP connector? Or what about Internet of Things – it needs messaging (WebSockets, MQTT, AMQP, …)? –  You can also build business applications via (micro)services, which implement your requirements and solve your business problems –  Deploy these services independently from each other with a standardized interface to a scalable runtime platform – automatically –  The services are decoupled and scale linearly across commodity hardware –  Think of an ESB as a “service delivery platform”, not just an integration platform “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.

26. •  Services implementing a limited set of functions •  Services developed, deployed and scaled independently Microservices “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.
27. Shorter time to results •  Scale development and reuse of services •  Use the right technology for the job Increased flexibility •  Change / improve any Microservice without major disruption on apps or other services Benefits of Microservices “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.
28. 28 Mhhh…. Sounds like SOA! “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.
29. Microservices clearly specify important differences to SOA (as we see SOA implemented in most enterprises today): •  No commitment to a unique technology •  Greater flexibility of architecture •  Services managed as products, with their own lifecycle •  Industrialized deployment •  Dumb routes and smart endpoints instead of a heavyweight ESB Sounds like SOA? Integra3on s3ll needed somewhere! “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.

31. Requirements for a Microservices Architecture ①  Service Contracts ②  Exposing new and existing Services ③  Discovery of Services ④  Coordination Across Services ⑤  Managing Complex Deployments and their Scalability ⑥  Visibility and Correlation across Services “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.
32. Requirements for Microservices Architecture #1: Services Contract 32 “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.
33. 33 Service Contracts Service provider express the purpose of the Microservice, and its requirements Other developers can easily access this informa3on Service contracts, and the ability for developers to discover them, serve that purpose. “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.
34. •  Examples: Java Interface, JMS, SOAP, REST, … •  In Practice today: –  SOAP: Internal, standards-based, XML Schema, easy mappings and transformations, performance no issue (anymore) –  REST (i.e. RESTful HTTP without HATEOAS): External, XML or JSON, Good architecture for mobile devices (simplicity, separation of concerns, no state, uniform interface) –  Messaging (e.g. WebSockets, MQTT): Good for thousands of devices and millions of messages (Internet of Things!) •  De facto standard for Microservices as of today: REST •  Internet of Things will move Messaging forward! 34 Technologies for (Micro)Service Contracts “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.
35. Requirements for Microservices Architecture #2: Exposing new and existing Microservices “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.

37. Smart endpoints and dumb pipes “When building communica3on structures between different processes, we've seen many products and approaches that stress pukng significant smarts into the communica3on mechanism itself. A good example of this is the Enterprise Service Bus (ESB), where ESB products o#en include sophis6cated facili6es for message rou6ng, choreography, transforma6on, and applying business rules. The Microservice community favours an alterna6ve approach: smart endpoints and dumb pipes. Applica6ons built from Microservices aim to be as decoupled and as cohesive as possible - they own their own domain logic and act more as filters in the classical Unix sense - receiving a request, applying logic as appropriate and producing a response. These are choreographed using simple RESTish protocols rather than complex protocols such as WS-Choreography or BPEL or orchestra6on by a central tool. The two protocols used most commonly are HTTP request-response with resource API's and lightweight messaging. The best expression of the first is Be of the web, not behind the web -- Ian Robinson” h\p://mar3nfowler.com/ar3cles/microservices.html#SmartEndpointsAndDumbPipes “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.

However, be aware that you have to do “ESB tasks” (integra3on, rou3ng, transforma3on, etc.) in the service then! à  Op3on A: Build (REST) Microservices with plain source code or a framework à  Op3on B: Use a tool to generate that code for (REST) Microservices, and choose the technologies you need ESB - as defined in this talk – has nothing to do with WS-*, BPEL, or other specific technologies! “Microservices = Death of the ESB?” by Kai Wähner © Copyright 2000-2016 TIBCO Software Inc.
