How does the E2E CDN improve content delivery?
A: E2E CDN caches static content (e.g., images, scripts) at global edge locations for low-latency delivery. Create a CDN in MyAccount, configure SSL, HTTP versions, and cache settings. Monitor bandwidth usage and invalidate caches to refresh content, ensuring fast, secure global access.
What is a Virtual Private Cloud (VPC), and how do I set it up?
A: A VPC is an isolated virtual network for secure resource deployment. Create it in MyAccount under Networking > VPC (Beta), choosing hourly or committed plans. Attach nodes via the Network tab, and manage settings like renewal or deletion. Traffic within a VPC is not counted against bandwidth.
How do I configure DNS records on E2E Networks?
A: In MyAccount under Networking > DNS, add a domain and public IPv4 for the SOA record. Update nameservers at your domain provider. Add records (A, AAAA, CNAME, MX, TXT, SRV) via the Edit DNS Record page. Configure Reverse DNS for E2E IPs with a PTR record.
How do Security Groups enhance node security?
A: Security Groups act as virtual firewalls, controlling inbound/outbound traffic for nodes. Create them in MyAccount under Networking > Security Groups, defining protocols and ports. Attach multiple groups to a node, ensuring at least one remains. Default outbound allows all traffic; restrict for better security.
