1. DEVELOPING REAL-TIME, FULL-STACK APPLICATIONS – AN AWS CASE STUDY RENALDI GONDOSUBROTO
2. AGENDA #1 The Motivation #2 Designing an Architecture #3 The Code #4 Understanding Value #5 Tips and Tricks Flutter Global Summit'21 2
3. A BIT ABOUT MYSELF • 12x AWS Certified and TOGAF 9 Certified® • Personal field of interest is in security practices, architecting solutions, and having fun with new tools • On the side: Running meetups, the occasional hackathon, and VR tech enthusiast Renaldi Gondosubroto Project Lead and Developer Advocate @ GReS Studio @Renaldig @renaldigondosubroto Flutter Global Summit'21 3
4. WHY HOST WITH AWS? • Serverless solutions • Functions, databases and solutions in one place • Amplify being a great solution for deploying full stack with Flutter, especially with the release of Amplify Flutter Flutter Global Summit'21 4
5. RESEARCH • Understand your business requirements before developing (e.g. would AWS fit your needs?) • What is the objective of your app? • How much extra resources do you need to invest into better understanding AWS? • What are potential alternatives that you may be comfortable with? • Metrics, metrics, metrics!

8. A MORE HOLISTIC VIEW ON THE AWS BACKEND Flutter Global Summit'21 8
9. ADDING AMPLIFY IN IS NO HARDER THAN A FEW LINES OF CODE! Flutter Global Summit'21 9
10. DATA MODELING Flutter Global Summit'21 10
11. A GENERATED GRAPHQL DATA MODEL Flutter Global Summit'21 11
12. INTEGRATION OF FLUTTER AND AMPLIFY PART 1 Flutter Global Summit'21 12
13. INTEGRATION OF FLUTTER AND AMPLIFY PART 2 Flutter Global Summit'21 13
14. OBSERVING DATA Flutter Global Summit'21 14
15. SETTING UP AUTHENTICATION 1. Authenticate and get tokens User pool 3. Access AWS Services with credentials Exchange tokens for credentials Identity pool AWS Cloud (Other) services Flutter Global Summit'21 15
16. THE CULTURE OF SYNCHRONIZATION Flutter Global Summit'21 16
17. ADDING IN APIS AND EXTRAS Flutter Global Summit'21 17
18. DEFINING METRICS • What are previous key KPIs you have used? • Measure responses handled by backend • Network performance Flutter Global Summit'21 18
19. MONITORING PERFORMANCE Flutter Global Summit'21 19
20. UNDERSTANDING VALUE – THE CASE STUDY • Smoother performance on the Cloud with serverless solutions • Focus more on the development on the app itself • Learning from use cases from others Flutter Global Summit'21 20
21. WHAT WE GOT OUT OF IT – CASE STUDY WRAP • Less time spent on working on the backend and more time on building value for users • User satisfaction with the experience • Innovation for the long term Flutter Global Summit'21 21
22. YOUR OWN BUSINESS USE CASE • Who is your target audience? • Are there any third parties involved that may be affected by the change? • How managed does your solution need to be? • How much time do you have to research? Are you willing to spend extra for specialists? Flutter Global Summit'21 22
23. TIPS AND TRICKS BE AGILE! PRIORITIZE CUSTOMER VALUE OVER ALL METRICS WILL HELP YOU MEASURE IN EVERY STEP Flutter Global Summit'21 23
24. CONCLUSION INVESTMENT • It pays in the long run VALUE • Users will appreciate the value you bring USABILITY • Build onto the usability on your apps DESIGN • Spend more time on the design for the experience FEEDBACK • Work iteratively to continually get feedback from users as part of an agile process FUTURE • Work towards a specified plan for the future with metrics Flutter Global Summit'21 24
