CASE STUDIES
Network engineering case studies
Design, automation, and operations
Real work for ISPs, data centers, and hosting providers, design, automation, and day-to-day operations.
Each write-up has the detail engineers actually want: the problem, the architecture, the tooling, and how it held up. Start with whichever one is closest to your own network.
