Number of Nginx Worker Processes by Fargate Task Size
Just a memo.
Nginx has a setting that sets the number of worker processes to auto, delegating the count to the number of CPU cores.
1 | worker_processes auto; |
I investigated how many processes this results in for various Fargate task sizes.
Results
| cpu | mem | number of nginx worker processes |
|---|---|---|
| 256 | 512 | 2 |
| 1024 | 2048 | 2 |
| 2048 | 4096 | 4 |
When I increased the task size, the worker process count properly grew with auto.
By the way,
even if the number of processes increases, you can’t change the net.somaxconn value on Fargate, so
to handle more requests, it’s better to increase the number of tasks.
Also, the following cost the same amount ♪
- cpu=256, mem=512 × 8 tasks
- cpu=2048, mem=4096 × 1 task
Let’s increase the number of tasks!
