The F.A.S.T. Cloud SDK server can be deployed on public cloud
infrastructure. The following issues are address in this FAQ.
Content Deliver Network (CDN)
Cloud based apps can be run faster if certain static files are cached
on a browser or provided by a CDN. Among external files,
socket.io.client can be loaded directly from external CDN. For
Fovia's SDK, the minified version of foviaAPI.js can be served over a
CDN. In addition, any \static images or artwork can
also be served over CDN. The images will of course be streamed live.
Reverse proxy setup
The server requires sticky sessions in order to make sure that once
connection is established between a client and same server.
Load balancer
The SDK requires a minimum of 8 cores and 8GB of memory The
actual number of cores per user depends on
many factors, including the size of the dataset, complexity of the
transfer function, number of viewports (and if the viewports are
linked), segmentation, quality / performance settings, etc. 3D
volume rendering and full-volume MIP require the most computational
power, while MPR and 2D imaging are substantially less. For detailed
discussion regarding the number of cores per users, please contact
your Fovia representative.
Running as a service on Linux (Ubuntu)
The following steps describe how to automatically launch the Fovia server
on Linux.
Add the following text to
/etc/systemd/system/.service. This assumes the
deliverables are deployed in /home/ubuntu/websdk_ubuntu; update the below script if the path is a different location.
Reload the configuration by executing sudo
systemctl daemon-reload
Start the service by using command below sudo systemctl start my_service.service Enable the service to run automatically on startup by executing start sudo systemctl enable
my_service.service.
