Infrastructure
Cloud & Networking
AWSSvix uses AWS as its cloud service provider (CSP), that provides compute, power, storage, and other application services over the Internet. Customer Content is stored and processed only in the AWS region selected by the customer.
Unused by default. Custom URLs are powered by Cloudflare, so customers who enable that feature have Customer Content pass through Cloudflare's network in transit. Customers who have not enabled custom URLs have no Customer Content processed by Cloudflare.
Observability
