96 saved links, 2018–2026 (peak: 2023) — the smallest of your infrastructure tags, but dense. One author anchors it (Ivan Velichko’s iximiuz labs, saved again and again), one cloud dominates it (Azure, naturally), and the newest saves ask the 2026 question: what does networking look like when the clients are agents?
