Hexagonal Architecture image missing again :-)

[qmacro]

The Hexagonal Architecture image, used in https://cap.cloud.sap/docs/get-started/concepts#hexagonal-architecture, is missing again:

This time, I'm guessing it's due to a problem with the certificate for https://alistair.cockburn.us/hexagonal-architecture:

meaning it will only be served via HTTP (not HTTPS).

(Also, I notice that the image's alt text in the Markdown:

[Hexagonal architecture basic.gif](https://alistair.cockburn.us/hexFig1.png)

is a little inaccurate (it's not a GIF), and should anyway just be non-technical, e.g. "Alistair Cockburn's Hexagonal Architecture diagram").

Do we want to create (and thus be able to store and serve) our own version of the diagram, perhaps?
