🛠 Watchman.

Интересный инструмент в репозитории Facebook - watchman. Позволяет отслеживать состояние файлов, и по мере их изменения триггерить нужные действия, если потребуется (запускаем что-то, собираем что-то, уведомляем и т. п.).

KeyDB - A Multithreaded Fork of Redis

John Sully disagrees with Salvatore Sanfilippo’s thoughts on multithreading, so he make own Redis, with multhithreading and enterprise features.

KeyDB have:
- 60% lower latency
- direct backup to AWS S3
- FLASH storage support

KeyDB designed with AWS in mind and has full compatibility with the Redis protocol, modules, and scripts. This includes full support for transactions, and atomic execution of scripts.

Походу, ребятам из GoJek было мало существующих решений в сфере L7 прокси, по этому они запилили свой. 🤷‍♂️🤷‍♀️ Назвали - Weaver.

Teleport

Если у вас в компании принято раздавать всем доступы на все сервера - у меня есть плохие новости. А если это делается мануально, то очень плохие.

Смотрите, есть вот такая тема:
https://gravitational.com/teleport

Teleport позволяет контролить доступ, логгировать выполненные команды и прочее. Очень удобно, например, для долгих Ansible деплоев: когда ноут не тянет кучу хостов, а на сервере с Teleport есть для этого достаточно ресурсов.

Teleport отлично миксуется с паттерном bastion host и отлично его дополняет. Мы используем, мы довольны, рекомендую.
