Saving another 100TB of RAM with math (and Rust)

Cloudflare engineers used Rust to develop a new memory allocation algorithm that has saved the company 100TB of RAM. The new algorithm, called 'Virtualized Memory', was implemented in Rust and reduces memory fragmentation by allocating memory in larger chunks. This reduces the overhead of memory management and frees up previously unused memory. The algorithm was tested on a cluster of servers and resulted in a memory reduction of 100TB, which is equivalent to 2.5% of Cloudflare's total memory usage. The new algorithm is now being used in production.
