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

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

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

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

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)

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

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

Dumb is better than Smart?
Huh??

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

The key: message-managed
state

16. Implemented as Coarse Grained “Server Processes”
Each
Microservice
ideally runs
in a separate
‘server
process’
Possible to
club multiple
microservice
processes
into a single
process
Each container can support multiple
server processes
Threads are
too ‘fine
grained’
Process-level
execution
preferred in
practice
Document-centric Interfaces
XML JSON
Microservices in Practice

17. Microservices in Practice …. (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

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”
