Micro = small enough …
One thing done well ! (Single Responsability Principle)
One small Team that must be able to work independently
• Two Pizza Team / Something that could be (re)written in two weeks
• Scrum Team (3-9 people) in one Sprint (2-4 weeks)
Sprint

Which Technology ?
Since each service is independent and gets
packaged as a separate isolated application in a
Container, each microservice can be developed
using the best technology for that functionality
Independent + Isolated = Polyglot Architecture + Cloud

MsA Vs SOA: (Micro) Service Oriented (Architecture)
Car evolved over the years (dust, petrol, diesel, electricity, …) but it’s STILL A CAR Similarly MsA leverages innovations but they ARE still SERVICES !
Microservices = SOA + AGILE DevOps + CLOUD Containers

MsA & SOA
Applications that should be optimized for:
rapid feature development
react rapidly to changing customer & business needs
(i.e: systems of engagement applications)
MsA typically are used for applications that require to be agile …
…SOA applies for reliability applications
Applications that should be optimized for:
reliability (slow down the rate of change)
don't get defects that damage the enterprise datas
(i.e: systems of record)

MsA & SOA: living togheter as allied
Microservices Architecture applies at the “intra-Application” layer…
…ESBs are used at the “inter-Application” layer
It is common to see both, traditional SOA based ESBs co-exist with microservices
architectures in an enterprise landscape
