11. Today is perhaps one of the best times to be entering the field of software and technology.
12. A plethora of languages & frameworks
13. A plethora of platforms, tools, and IDE’s
14. ...and tools to build, run and monitor
15. Providing for your data center needs And supporting a range of different architectures: monolithic, µ-services, stateful, serverless, event-driven, reactive, streaming, ...
16. Let’s examine some of the nuances of API-based platforms.
17. A µ-services -based approach entails building the application as a suite of small services, each running in its own process and communicating via lightweight mechanisms, often an Http Resource API. Source: https://martinfowler.com/articles/microservices/images/decentralised-data.png
18. Applying the principles of domain-driven design(DDD) to identify the different bounded contexts in the system. Source: https://martinfowler.com/bliki/images/boundedContext/sketch.png
19. Using RESTful API designs to wire the consumers to your services, and resources. Source: https://www.systango.com/blog/wp-content/uploads/2017/04/rest-working.png
20. Using a service mesh to separate the platform concerns. ➔ Routing ➔ Load balancing ➔ Health checks ➔ Service discovery ➔ Rate limiting ➔ Circuit breaker ➔ Distributed tracing Source: https://www.nginx.com/wp-content/uploads/2019/02/service-mesh-generic-topology_social.png Source: https://miro.medium.com/max/3264/1*DIV3ZADt68hff9_mDIKLug.png
21. Additional concerns to ease operations and adoption: ➔ Independent deployments and scaling ➔ Monitoring the health and performance of APIs ➔ Usable API documentation to increase adoption Source: https://petstore.swagger.io
22. Let’s examine some of the relevant memes in software delivery today.
23. 1. Using TDD to iteratively improve the design of the system. With confidence. The Red-Green-Refactor feedback loop. Source: https://www.techwell.com/techwell-insights/2018/12/keep-your-code-base-clean-regular-refactoring/
24. What the experts say Tests are the programmer’s stone, transmuting fear into boredom. Kent Beck Nothing makes a system more flexible than a suite of tests. Uncle Bob If your code is not testable, then it is not a good design. Michael Feathers
25. 2. Using CI/CD pipelines to automate the build, test, and release processes. Source: https://docs.gocd.org/current/images/home-image1.svg
26. 3. Using the four key metrics to measure the team’s performance and effectiveness. ➔ Lead Time ➔ Deployment Frequency ➔ Mean time to restore (MTTR) ➔ Change Failure Rate Source: https://images-na.ssl-images-amazon.com/images/I/610tbJ%2BV-aL.jpg
27. 4. Using fitness functions to measure how close the architecture is towards meeting its design goals. “It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.” – Charles Darwin Source: https://martinfowler.com/articles/evo-arch-book.jpg
28. 5. Integrating security testing earlier in the delivery lifecycle, i.e. DevSecOps. Source: https://devopedia.org/images/article/121/8646.1538504518.png Source: https://jaxenter.com/wp-content/uploads/2018/05/devsecopsgraph-1024x500.png

30. Responsible Tech “Those who have the privilege of creating products have the responsibility of defining ethical effects, as well as forecasting effects and ensuring that they pose no significant harm.” Katherine Zhou Product Designer @ IBM
31. Incidents with potential for damage
32. 32 References: https://uxdesign.cc/designing-ethically-pt-2-535ac61e2992 The consequences of not incorporating ethical thinking can be devastating to our identity, health, business, economics, political systems and our social cohesion.
33. Where ethical behaviors matter to us
34. Ethics and the bottom line Over 3 years, the TYPICAL ETHICAL FUND is up by around 32%-35%, compared with 28% for the FTSE All-Share index and 24% for the AFI Balanced index. 56% of millenials have ruled out working for an organisation that doesn't align with their VALUES. Deloitte Millennial Review 2016 68% of global consumers would remain LOYAL to a brand if the organization practiced social responsibility. Martin Zwilling, Forbes
35. 1. Using the Ethical OS toolkit to shape the strategy, process, and values of a company and its products and services. ethicalos.org
36. 2. Using the Tarot Cards of Tech to think about the impact of your product and technology. From multiple perspectives. www.artefactgroup.com/case-studies/the-tarot-cards-of-tech/
37. 3. Using the Data Ethics Canvas to help identify and manage the ethical issues of your data project. theodi.org/article/data-ethics-canvas/
38. ...ethics of AI lies in the ethical quality of its prediction, the end outcomes drawn out of that and the impact it has on humans.
