Thoughts on systems, infrastructure, and engineering
HTTP/2 introduced multiplexing, allowing multiple requests and responses to be interleaved on a single TCP connection. This fundamentally changes how we think about connection management and resource loading priorities in modern web applications.
Docker networking modes each serve different purposes. Host mode eliminates NAT overhead entirely, bridge mode provides isolation, and overlay networks enable multi-host communication. Choosing the right mode depends on your latency requirements and security posture.
TLS 1.3 reduces the handshake from two round trips to one, and supports 0-RTT resumption. Combined with QUIC, we are approaching a world where encrypted connections have negligible overhead compared to plaintext.
