Ported to Cloud with Wing_ Blue ZnZone app from _Hexagonal Architecture Explained_.pdf

Presentation to Wing wing community. Porting "Blue Zone" application featured in the "Hexagonal Architecture Explained" book.

1. Ported to
Cloud
Presenter: Asher Sterkin
Software Technology Expert

2. “Lift-and-Shift” to Cloud Seldom Works Well
Directly porting software
applications to the cloud
often results in a system
that is more fragile, more
expensive, less secure,
and less performant.

3. Winglang + Hexagonal Architecture is a Better Choice
Using the new cloud-oriented
programming language Wing
in combination with
Hexagonal Architecture has
proven to be a winning
combination striking the right
balance between cost,
performance, flexibility, and
security.

11. Topics for Discussion and Further Research
1.“Stuff vs Value” Metrics
a.Total: 55
b.src/application: 16
c.src/: 41
d.Files: 43
e.Strict Value to Stuff Ratio: 16*100/55 = 29.09%
f.Extended Value to Stuff Ratio: (15+19)*100/42 = 74.55%
2.HTTP error status code vs. HTML screens
3.Copilots and Code Generation
4.Wing extensions from endor.w
