The Architectures of Microservices: The Next Layer

My µCon 2016 session presentation slides. This was about introducing PGAS (partitioned global address space) as a new architectural form for use in microservices systems. As always I draw on the slides as I speak and this is not captured here, you need to watch the video https://skillsmatter.com/skillscasts/8737-on-the-architectures-of-microservices-the-next-layer

17. Copyright © 2016 Russel Winder 17 µservices – The Belief System • Services should be small – whatever small means, whatever service means. • Services can use other services over some communications mechanism – usually a network but could be a bus. • Communications should be fast with low latency. • Communications should be asynchronous.

19. Copyright © 2016 Russel Winder 19 Each is a thing providing some entry points to some computation.
20. Copyright © 2016 Russel Winder 20 Encapsulated state Possibly independently active Various entry points Responsive to requests
21. Copyright © 2016 Russel Winder 21 Active Object
22. Copyright © 2016 Russel Winder 22 Last Year • Pipelines • Dataflow • Graphs • CSP • Actors • Active objects Message passing
23. Copyright © 2016 Russel Winder 23 Most services just do a trivial database lookup and return some (JSON) document.

26. Copyright © 2016 Russel Winder 26
27. Copyright © 2016 Russel Winder 27 Some services may, just may, actually do some serious computation.

38. Copyright © 2016 Russel Winder 38 Are µservices just active objects on computing clusters?

40. Copyright © 2016 Russel Winder 40 Software is about abstraction… Programming is about creating abstractions.
41. Copyright © 2016 Russel Winder 41 Abstraction • We have abstracted out: – Stack – Heap – Cores – Synchronisation – (Processors) • Using the units of abstraction: – Functions – Classes and methods – Thread pools – Processes Message passing
42. Copyright © 2016 Russel Winder 42 What’s left to abstract?
43. Copyright © 2016 Russel Winder 43 The Networks.
44. Copyright © 2016 Russel Winder 44 Some of them anyway.
45. Copyright © 2016 Russel Winder 45
46. Copyright © 2016 Russel Winder 46 The 1980s • Transputers. • Serial connection networks. • Bus networks. • Individual address spaces. • Global address space.

51. Copyright © 2016 Russel Winder 51 Mid-2000s onwards • HPCS programme by DARPA. • Many stages, many projects. • All now over, any work now self-sustaining. • Only X10 and Chapel left, but these are now making serious inroads into the use of FORTRAN, Fortran, and C++.
