Microservice: Do one thing, but do it right!

What is a Microservice?

9

VPCloudArchitectureAmazonWebservicesFormerCTONetflix

Service-oriented architecturecomposed ofloosely coupled elements

that havebounded contexts


10



Services communicate with each other over

the network (internet)


11



You can update the services

independently; updating one service

doesn’t require changing any other

services.


12



Self-contained: You do not need to know the

internals of other Microservices, strict interaction via APIs

How are Microservices different from a SOA?

13

Communication

SOA Microservices

SOAP JSON / Binary

Service Definition WSDL Swagger / JSON Schema

Service Interface Webservice REST-APIs

1. Fast Networks & Low Latency: Allow high amount of Microservices-Calls

2. Developer Friendly: JSON has reached much larger audience, esp. Web-Developers

3. Pragmatic: Standards set by successful tech companies, not by industry consortiums

Granularity Medium/Small Small/Micro

14

Unparalleled scale and innovation thanks to Microservices

Microservices are on the roadmap

2API-First: Create reliable boundaries

All our services have REST-APIs documented /w Swagger

28

REST-APIs are great – but have performance limits

29

/applications /capabilities

GET GET

Display interactive reports very fast Many requests & unnecessary network load

Generic REST-APIs create unnecessary effort

}

• JSON-based query language to request required data

• Graph-based access to EA data

• Strongly typed API for each LeanIX workspace (full multi-tenancy)

Example: One request to build report
