3 Modularity and Microservices

4 moving to modularity agility deployment testability performance scalability simplicity reliability

5 moving to modularity agility deployment testability performance scalability simplicity reliability

6 moving to modularity agility deployment testability performance scalability simplicity reliability

7 microservices architecture

8 microservices architecture

9 microservices architecture distributed architecture bounded context scalability application availability deployment testability

10 microservices architecture business applications?

11 microservices architecture

12 moving to modularity agility deployment testability performance scalability simplicity reliability

13 moving to modularity agility deployment testability performance scalability simplicity reliability

14 service-based architecture

15 service-based architecture prag mat ic praɡˈmadik/ adjective adjective: pragmatic 1. dealing with things sensibly and realistically in a way that is based on practical rather than theoretical considerations.

16 service-based architecture service granularity database scope deployment pipeline

17 service-based architecture service granularity client requests client requests client requests api layer

18 service-based architecture service granularity client requests client requests client requests user interface layer

19 service-based architecture service granularity tradeoffs performance robustness domain scope service development service testing deployment pipeline

20 service-based architecture database scope client requests client requests client requests api layer

21 service-based architecture database scope client requests client requests client requests user interface layer

22 service-based architecture database scope client requests client requests client requests user interface layer

23 service-based architecture database scope tradeoffs performance feasibility service coupling schema changes

24 service-based architecture deployment pipeline

25 service-based architecture deployment pipeline

26 service-based architecture deployment pipeline tradeoffs no devops complexity no organizational change lack of quick deployments poor continuous delivery model

27 Case Study

28 electronics recycling application public requests receiving department recycling and accounting kiosk quote receiving accounting item status assessment recycling reporting

29 electronics recycling application kiosk public ui receiving ui recycling ui

30 electronics recycling application kiosk public ui receiving ui recycling ui

31 moving to microservices

32 service-based architecture adding microservices client requests client requests client requests user interface layer

33 service-based architecture adding microservices client requests client requests client requests user interface layer

34 service-based architecture adding microservices client requests client requests client requests user interface layer

35 Service Design Considerations

36 service design considerations client requests client requests client requests user interface layer?

37 service design considerations direct access design api access design

38 service design considerations direct access design user interface / api layer

39 service design considerations public class public String getname() { //logic to get name... public class public String getcontactinfo() { //logic to get contact info... } }

40 service design considerations api access design user interface / api layer api / access facade

41 service design considerations api access design user interface / api layer api / access facade super mapi mapi mapi msg api super msg api

42 service design public class public String getnamerequest() { //invoke separate class to get public String getcontactinforequest() { //invoke separate class to get contact info... }...

43 service design considerations api access design variants service-based api domain-based api resource-based api

44 service design considerations api access design benefits separation of concerns protocol-agnostic processing service context / binding service catalog

45 Service-Based Architecture vs. Service-Oriented Architecture

46 service-based vs. service-oriented service-oriented architecture service-based architecture enterprise scope heterogeneous integration middleware capabilities multiple databases strict service taxonomy application scope limited integration no middleware single database no service taxonomy
