PostgreSQL and other stateful databases pay for I/O isolation, stable clocks and predictable licensing. Here is when bare metal is the cheaper and quieter option.
RPKI and BGP security: a primer for infrastructure operators
Route origin hijacks are operational events, not conference slides. This primer covers ROAs, origin validation and what to demand from an upstream.
