This document summarizes a presentation by Jason Bloomberg on integrating microservices in the cloud. Jason Bloomberg is the president of Intellyx and advises companies on digital transformation initiatives. The presentation discusses what microservices are, how to design them for qualities like granularity, parsimony and cohesion. It also covers challenges of integrating microservices in the cloud, including managing state across ephemeral instances and asynchronous interactions.

- 4. What are Microservices? • Fine-grained units of execution – Designed to do one thing very well – Contain everything from the operating system, platform, framework, runtime and dependencies, packaged as one unit of execution • Microservice architecture – Promotes developing and deploying applications composed of independent, autonomous, modular, self-contained units Copyright © 2015, Intellyx, LLC4 Quote:JanakiramMSVhttp://www.computerweekly.com/feature/Microservices-How-to-prepare-next- generation-cloud-applications PhotoCredit:JamesLeehttps://www.flickr.com/photos/jronaldlee/
- 5. Microservice Granularity • “Granularity” a vague term • More appropriately applied to interfaces than to code • “Fine grained” microservices can (and often should) have coarse-grained interfaces Copyright © 2015, Intellyx, LLC5
- 6. Parsimony • As small as they should be but no smaller • As part of refactoring, ask: – Would this microservice work better if it were smaller? – Would this microservice work better if it were split into two or more microservices?

- 7. Cohesion • Microservices should do one thing well • Principle of modular programming since the 1960s • Web Services often suffered from low cohesion Copyright © 2015, Intellyx, LLC7
- 8. Microservices & Containers • Containers support lightweight, rapid scalability & elasticity • Microservices well-suited for containers • Challenges: – Managing state – Keeping track of everything – Integration, especially in dynamic environments Copyright © 2015, Intellyx, LLC8
- 9. Microservices vs. Web Services • Web Services are contracted interfaces – WSDL + other policy documents form the contract (all XML) – Abstract underlying software • Microservices are units of execution – Container-centric (although containers not required) Copyright © 2015, Intellyx, LLC9
- 10. SOA & Microservices • SOA Services suffer from “lipstick on the pig” problem – Complicated, problematic software exposed as Services still complicated & problematic • Call for key best practices underlying Service interfaces – Highly modular, “shared nothing” code – Independently deployable – Easy to distribute & scale Copyright © 2015, Intellyx, LLC10 What SOA Services should have been all along PhotoCredit:NeilTurnerhttps://www.flickr.com/photos/neilt/
- 11. Smart vs. Dumb Pipes • Terminology from 2014 article by James Lewis and Martin Fowler of ThoughtWorks • “Smart” pipes are centralized, traditional ESBs that provide process execution environments (e.g. BPEL engines) • “Dumb” pipes are lightweight and platform-agnostic – RabbitMQ for example Copyright © 2015, Intellyx, LLC11 Dumb is better than Smart? Huh?? PhotoCredit:RreneSchwietzkehttps://www.flickr.com/photos/rene-germany/
- 12. Challenges of Cloud Integration • Instances (either VMs or containers) are ephemeral – Scale up or down – Any identical instance can respond to a request • Interactions may be asynchronous Copyright © 2015, Intellyx, LLC12
- 13. Microservices & State • If a microservice is keeping track of something & it goes away or a request is routed to a different microservice instance, what happens to state information? • Caching may be part of microservice • Storing state information in persistence tier doesn’t scale well Copyright © 2015, Intellyx, LLC13 The key: message-managed state PhotoCredit:KevinHutchinsonhttps://www.flickr.com/photos/hutchike/

(2) No external dependencies! • Each Microservice contains all the code/libraries required for independent execution • Allows Microservices to be deployed across cloud, hybrid and on-premise networks Attached GUI for each Microservice • Each Microservice has an independent Graphical User Interface • Each Microservice can be developed in one or more programming languages • Multi-language (Java, C, C++, C#, Scripting languages), multi- platform architecture

- 25. A Case Study – Delaware North Companies “Fiorano’s peer-to-peer servers, the way they could scale, was compelling – even before the cloud. Fiorano had a very elegant solution.” Kevin Quinlivan, CIO, Delaware North Find full interview on Forbes article "Peanuts, Popcorn, Crackerjack -- And Mobile- First, Digital SOA” by Jason Bloomberg
- 26. A Case Study – Delaware North Companies Challenges • Unstructured data • Manual data process • Lack of real-time data access • Disparate applications Result • A unified business intelligence dashboard • Real-Time data access, including to Mobile interfaces • Scalable, secure and reliable system in place for digital transformation Scott Mercer, Manager of the Service-Oriented Architecture (SOA) Solutions Team at Delaware North "Our partners and clients love the speed at which we get data back to them and the near-real-time analytics it can provide”
