4-2-6: The story about migrating AWS cloud infrastructure from IPv4 to IPv6
2025-02-04, 16:00–16:50, Tofu / Cloud (B.3.013)

We’re one of the few companies running a fully IPv6-native cloud solution. While AWS claims full IPv6 support, there are always caveats. Many well-known open-source tools we use also face IPv6 issues. I've led this migration twice — failed once, succeeded in my current role — and felt like I was pioneering it both times. This experience could benefit others.
