The Data Centre in the Age of Microservices

Hannover,

March 2016, Gunnar Menzel

Monolithic SOA Microservices

A New Era?

Microservices are not always the right answer

Monolithic and SOA have (and will have) still a place in IT going forward

Microservices



What Are Microservices?

<2000Monolithic Approach / 1st Platform

One Size Fits All

A software design pattern that

includes all functional and non-

functional features into one “box.”

>2010Microservices / 3rd Platform

Superfine

Independent application services

delivering one single business

capability in an independent, loosely

connected and self-contained

fashion.

2000–2010Service-oriented / 2nd Platform

Fine-grained Components

SOA is mainly about “exposing”

discrete components of an

application as web services.



Microservices 7 Key Design Principles

A ‘Good’ microservice has / are / have

1. fine-grained capabilities that are stateless and are “stupid”

2. well defined interfaces which ‘hide’ how the service is executed

3. a ‘very loosely-coupled’ approach

4. “disposable”, & “no ESB - “dumb pipes and smart services”

5. autonomous, explicitly versioned & highly independent

6. stupid – ie “do one thing, and do it well”

7. cost and value fully defined

ESB = Enterprise Service Bus



The Transition from Mainframe, Client/Server to Microservices will form

a new Data Center Blueprint

Following the Lego-based Principle, Infrastructure Services should be

constructed using Technology and Business Characteristics
