: Using software to automatically identify and catalog devices, services, and connections across a network. Data Discovery
| Need | Better Protocol | |------|----------------| | Recursive directory discovery | HTTP WebDAV with PROPFIND | | Secure file listing | SFTP (SSH) | | Programmatic asset enumeration | S3 ListObjectsV2 | | Real-time cache contents | CDN API (e.g., Fastly Purge API + logs) |
Here is a draft of a post—suitable for a LinkedIn update or an internal workspace (like Slack or Teams)—announcing the completion of the work or sharing instructions for peers. Option 1: The "Job Done" Update (Announcing Completion) 🚀 Content Upload Complete: [Project Name]
For the engineers managing cdn1discovery nodes, this work involves monitoring transfer logs, troubleshooting failed uploads, and ensuring that the "discovery" mechanism correctly identifies new assets. A failure in the FTP layer results in a broken link for the end-user—a "404 Not Found" error that represents a failure in the delivery chain. Therefore, the FTP work acts as the foundation of the reliability pyramid; if the base (transfer) fails, the apex (delivery) cannot exist.
Use secure transfer methods and automation with robust checksums and manifest-driven ingestion. Standardize directory layout and naming to ensure downstream systems integrate smoothly.
: Secure FTP (SFTP) typically uses Port 22 , while standard FTP uses Port 21 .
