infrasturctures

I’m been wondering what’s running behind the scenes. I see system admins talking about prices from time to time, so I take notes.

Case: linux mirror (Jan. 2025)

mirrors.kernel.org transfers ~1PiB of data weekly. At Equinix Metal’s list price of $0.05 per GB, it would cost us roughly $200, 000 a month to operate these systems

Case: freedesktop’s gitlab servers (Jan. 2025)

A very insightful post from FDO’s system admin.

Case: elxir.bootlin .. the source code indexer

At Bootlin, here are a few details about the server we’re using: As of July 2019, our Elixir service consumes 17 GB of data (supporting all projects), or for the Linux kernel alone (version 5.2 being the latest), 12 GB for indexing data, and 2 GB for the git repository.

We’re using an LXD instance with 8 GB of RAM on a cloud server with 8 CPU cores running at 3.1 GHz.
