1. Eric Horesnyi | streamdata.io Network-based Architectures Fowler, Fielding, and Haussmann
2. The « Digital » gap @StreamdataIO #JAXLondon
3. Haussmann & Fielding 1853, Paris 2000, Irvine @StreamdataIO #JAXLondon
4. Mission Network performance throughput, small overhead, bandwidth User-perceived performance latency, and completion Network-efficiency avoid using the street too much. Homeworking Napoleon III describing his mission to Haussmann, 1853
5. CHALLENGES IN PARIS,1853 Haussmann Fielding and Fowler @StreamdataIO #JAXLondon
6. High Dropout Cholera, 1832 – 19,000 dropout @StreamdataIO #JAXLondon
7. Congestion 1hab/sq mt density @StreamdataIO #JAXLondon
8. Slow & Unsecure Security threats: No inspection possible obscure streets No patches to remove viruses and threats lack of air circulation Poor latency: slow access lines narrow streets Street in Ile de La Cité Early XIXth
9. Unstable system Full reboot 1789, 1815, 1830, 1848… No backward compatibility No service desk Restricted vote DDOS in small access lines Barricades Liberty Leading the People, July 28th, 1830' by Delacroix
10. INHERITED FEATURES HTTP//PARIS 1789-1853 Haussmann Fielding Fowler @StreamdataIO #JAXLondon
11. Inherited Properties @StreamdataIO #JAXLondon
12. DNS .gov, .com and .fr follow same scheme Seine is .root Streets start there Right/even Left/Uneven Paris street numbering, 1805
13. Famous heritage Napoleon, France 1804 Tim Berners-Lee, CERN ‘90 Comment: // limited to ability to establish basic rules. I do not admire Napoleon for anything else.
14. Separation of concerns Client Server @StreamdataIO #JAXLondon
15. Stateless All clients are treated equal, no special treatment, no segregation Palais de Justice, Ile de la Cité
16. SELECTION OF PROPERTIES FIELDING // HAUSSMANN REST // PARIS Haussmann Fielding Fowler @StreamdataIO #JAXLondon
17. KPIs Haussmann // Fielding Scalable make it possible for Paris to grow Simple no need for a city-user manual, Modifiable ability to evolve in the future through change Extensible add new neighborhood Customizable specialize a building without impacting others Configurable easily modify a building post-deployment Reusable building can host a bakery then a cremerie Visible to provide best security and auditability Portable style should work well in other regions Reliable susceptible to failure (no single event could stop water, gas or circulation for citizens) @StreamdataIO #JAXLondon
18. P1: Low-Entry Barrier A popular neighborhood in Paris @StreamdataIO #JAXLondon
19. P2: Extensibility Streaming = Paris Metro/Subway, 1900 @StreamdataIO #JAXLondon
20. P3: Distributed Hypermedia @StreamdataIO #JAXLondon
21. P4: Anarchic Scalability Paris Metropole today, 10m+ people @StreamdataIO #JAXLondon
22. P6: Independant Deployment Ile de La Cité restructured, embedding legacy/sacred Notre Dame @StreamdataIO #JAXLondon
23. WHY HAUSSMANN DECIDED TO MAKE PARIS RESTFUL Haussmann Fielding Fowler @StreamdataIO #JAXLondon
24. REST=LCODC$SS&UI CSS=Client-Server-Stateless @StreamdataIO #JAXLondon
25. Layer 1: sewage & gas @StreamdataIO #JAXLondon
26. Layer 2: street & boulevards @StreamdataIO #JAXLondon
27. Layer 3: roofs @StreamdataIO #JAXLondon
28. Layered Networks Within a layer, a component connects to its neighboor Between two layers, gateways allow for interaction Each layer is autonomous @StreamdataIO #JAXLondon
29. Cache 700 concurrent clients 80,000 in cache 2m records @StreamdataIO St Geneviève Library, 1850
30. Stateless Client access server via a network call
31. Cache Opera, a server with cache @StreamdataIO #JAXLondon
32. Code On Demand Les Halles, setting the tone for all restaurants in the City @StreamdataIO #JAXLondon
33. Uniform Interface = Genious Codified UI, by floor (header), with token/key, proxy, cache @StreamdataIO #JAXLondon
34. Uniformity = beauty inside Uniformity in APIs brings harmony in UX @StreamdataIO #JAXLondon
35. Uniformity = pattern beauty Uniformity brings fractal harmony: still there from a distance @StreamdataIO #JAXLondon
36. HAUSSMANN // FOWLER AS URBANISTS Continuous Delivery & Microservices #Tech2Day @StreamdataIO #JAXLondon
37. Continuous Delivery Resilient Water Induction, requiring aqueducts and reservoirs @StreamdataIO #JAXLondon
38. Continuous Delivery Aqueduct, Arcueil Reservoir, Arcueil @StreamdataIO #JAXLondon
39. Microservices Not too big Autonomous components Own API Standard protocol Scalable @StreamdataIO #JAXLondon
40. Zoning Quartier Panthéon, a zone dedicated to “The Big Men”
41. Lead by example Opera, an Hypermedia API > great UX >>> traction for API owners
42. Cut Corners Haussmann corners: Most difficult piece & beautiful
43. Polyglot XVIII architecture encapsulated, if API complies @StreamdataIO #JAXLondon
44. PARIS 160 YEARS LATER HTTP REST 16 YEARS LATER Sustainable systems? @StreamdataIO #JAXLondon
45. UX performance City of Lights: 20m unique visitors a year
46. Reproductible Chicago after the Burnham Plan, designed in 1909
47. Durable Courneuve, 1986, 20y lifespan Monolith
48. Evolvable Tour Eiffel under construction, evolution built years after Haussmann had left office
49. DAYTODAY LIFE IN A RESTFUL CITY Haussmann Fielding Fowler @StreamdataIO #JAXLondon
50. Incomplete Protocol: Velib Leverage reusable assets Share same layer as existing traffic But incomplete protocol: collisions, missing RFC for cars Rate-limited API, realtime difficult @StreamdataIO #JAXLondon
51. Error Handling in your code Gare Montparnasse, 1895 –HTTP or REST does not prevent from good error handling, contrib @rit
