The document discusses extending on-premise applications to the cloud, focusing on the development of mobile applications that integrate with existing systems without disruptions. It highlights the use of AWS and various cloud tools, such as DynamoDB for mobile app data storage, to enable fast data retrieval and management. Intechnica emphasizes the need for proactive caching and flexibility in data handling to accommodate large datasets and ensure performance.

- 4. The Problem
- 5. Andy! I want a mobile app!!! I want it now! I want it to be brilliant!! But I don’t want it to interfere with any of my current systems in any way!!
- 6. OK!! I’ll get straight on it!!
- 7. Well..... How am I going to do that then?
- 9. Tight integration with other key internal systems Large datasets and legacy data structures Umbraco CMS integration Oracle Database .net 4 web forms application £1.5 bn transactions per yearB2B Order Capture System
- 10. Current System
- 11. Why AWS? Why not just build this on the current system?
- 12. Longer term ambition to open areas of the system to additional 3rd party uses Separation from core, business critical systems Platform Stressed at peak times
- 13. We’ll need to introduce an API on this system and a whole new platform for mobile...
- 14. Like This
- 15. How will the caching datastore work?
- 16. I’ll just fire up an RDS Oracle instance and sync the data
- 17. That seems a bit old style....
- 18. All data arriving in Json from API, shall we store it in that format Must be focussed on fast data retrieval All data will be read only, why the relational overhead? Can’t we build this on a smaller footprint That’s a lot of data to sync Those are heavy queries on the current system
- 19. What else does AWS have to offer?
- 21. What is needed?
- 22. Multiple dataset sizes - very large - >65mb - very small - <100kb Fast data retrieval Must proactively cache, shouldn’t be triggered by end user. Must be persistent and survive EC2 machine crash
- 23. No one size fits all....
- 24. .... But this is the cloud so it doesn’t need to.....
- 29. If only I could just use an Azure Worker role...
- 30. ... wait a minute... I can!
- 32. Now just need to share business logic across standard and mobile systems...
- 33. At least that will be easy. Thanks to Dependency Injection
- 37. Now where shall I store mobile application data?
- 39. Why?
- 40. It’s new, I want to play with it.
- 41. And if the client asks?
- 42. Intechnica: Chose DynamoDb for Mobile app storage Why Quick and easy to implement Very small chunks of data to store No issue around data integrity – don’t need full relational structure No complex querying required
