Levelling up to enterprise

Hello!

Was wondering if anyone had any good resources on scaling up a medium sized Laravel-based ecommerce business to be more enterprise ready.

I'm a self taught developer and though I try to learn everything that I can get my hands on, I feel like I am missing some core fundamental knowledge and best coding practice at scale, server uptime, code coverage in testing, release patterns etc..

Basically, I'm looking to start licensing our platform out and want to make sure that I am offering the best possible product while minimizing any ceiling on scalability and minimizing any downtime.

I've searched and can't seem to find anything - though to be honest, I probably don't even know what I'm looking for...

Any help on this would be greatly appreciated. Thanks in advance!!
