I use Xojo to build webservices, running on Ubuntu vm boxes. Recently I discovered, that Oracle is offering free virtual machines and those running on ARM are quite powerful (free tier contains up to 4 OCPU, 24 GB of RAM, 200 GB diskspace). One can get free vps on AMD as well, but then we are limited to 1 GB of RAM).
So it comes in handy that ARM64 for Linux is on top of the roadmap.

My Xojo webservices are mainly creating a link between Wordpress webpages and CubeSQLServer databases and Xojo desktop apps.
A great tool to quickly install the webservices, SSL secure them with Letsencrypt and easily update them is Lifeboat, by Tim Parnell. Strawberry Software - Lifeboat
I even used Oracle Clouds micro instance vps (1GB RAM) with Lifeboat and installed a Xojo webapp on it, and it runs astonishingly well. Once we have ARM64 support, I will use Xojo webapps on the more powerful Ampere instances in the Oracle Cloud. For free.
