I Have a question and I would really appreciate you if you could reply on it
Magento 2.4.2 added support for AWS S3 for media storage and they have guided configuration with Nginx in this page of docs Configure AWS S3 bucket for remote storage
My question is,
Can AWS S3 be configured with OpenLiteSpeed instead of Nginx as suggested in page ?
This will only work if proxypass is supported by OpenLiteSpeed.
As far as I know support for proxypass was just added to LiteSpeed Enterprise 6.0 recently so I doubt that OLS has support for it.
Anyway I don't believe it is recommended to use Magento with OLS anyway as you will miss out on the excellent LiteMage Cache. You should use LiteSpeed Enterprise instead which not just supports LiteMage Cache but also has more features and proper support.
Yes, AWS S3 can be configured with Open litespeed. Also you can go for a managed magento hosting, that offers litespeed server on aws. There are some good hosting providers out there that offers your requirements, you can match with their plans and choose that fits the best for you. Managed magento hosting can help your set your magento site on OLS with just a few clicks. And the site performance, speed and reliability will be optimized.
