- 15. Microservices
- 16. How did we get here?
- 22. Monolithic Applications Invoicing Inventory Logging Profiles Warehouse Orders Time To Build Size of Codebase
- 23. Monolithic Applications Invoicing Inventory Logging Profiles Warehouse Orders Time To Build Time To Test Size of Codebase
- 24. Monolithic Applications Invoicing Inventory Logging Profiles Warehouse Orders Time To Build Time To Test Size of Codebase We are getting better at writing code than getting it into production.
- 25. Service Oriented Architecture (SOA) Orders Invoicing Inventory Logging Profiles Warehouse
- 26. Orders Invoicing Inventory Logging Profiles Warehouse Service Oriented Architecture (SOA)
- 27. Orders Invoicing Inventory Logging Profiles Warehouse Service Oriented Architecture (SOA)
- 28. Orders Invoicing Inventory Logging Profiles Warehouse Tightly Coupled Service Oriented Architecture (SOA)
- 29. Loosely Coupled Orders Invoicing Inventory Logging Profiles Reporting Event Bus
- 30. Service Based Architecture • No point-to-point integrations • Loosely coupled, highly scalable systems • Loosely coupled, TEAMS • Easier to test • Easier to change • Topology agnostic
- 31. Easy to Integrate New Systems Orders Invoicing Inventory Logging Profiles Reporting Event Bus
- 32. Easy to Integrate New Systems Orders Invoicing Inventory Logging Profiles Reporting Event Bus New System
- 33. Scales Orders Invoicing Inventory Logging Profiles Reporting Event Bus
- 34. Inventory Inventory Inventory Scales Orders Invoicing Inventory Logging Profiles Reporting Event Bus
- 35. Other benefits • Ease of 3rd party integration • Existing systems can be ‘wrapped’ • Can be deliberate about scaling • Fault tolerant • Event messages can be logged and ‘replayed’ • Can test subsystems in isolation
- 36. DevOps is a Real Thing
- 43. …that you might need to develop
- 44. …that you might need to develop • Technical in nature • Http Verbs (POST, GET, PUT, PATCH, DELETE, OPTIONS) • Http Headers • ReST • API • More about networking than you would like • Oh, and you still need to know the business
- 45. Once you have developed these skills, a whole new world of testing capability becomes available to you.
- 46. Easy to Test
- 48. • Deliberately test your system at the physical boundaries • Know what your system does and how it works • Collaborate! Collaborate! collaborate!
- 49. • Deliberately test your system at the physical boundaries • Know what your system does and how it works • Collaborate! Collaborate! collaborate!

- 64. Use your web browser • Can only execute un-authenticated GET requests • Can only access web clients • Hard to set headers
- 66. Use a web “sniffer”
- 67. Use a web “sniffer” • Fiddler - more granularity, more technical http://www.telerik.com/fiddler
