20 year old cloud native apps with .NET

Talkat NDC London 2025 · 2025-01-27..01-31· [dotnet, legacy-modernisation]

Twenty‑year‑old .NET apps compile and run on modern runtimes: legacy site images and XML “database” (≈6,000 files) move from a 30 GB physical disk to containers, the blog becomes DosBlog.Core on .NET 8, and the stack runs on Linux and a Raspberry Pi. Migration uses Net Upgrade Assistant, DNS + Azure Front Door as a reverse proxy, multi‑stage Docker builds, Playwright for headless tests, and chiseled containers with tree‑trimming. Result: ~15 sites (2M monthly pageviews) for ~$41/month.
