Tiny Guide to Webscaling

Someone on Twitter asked what if Khairul Aming wanted to set up his own website for his sambal? For those who may not know, his product has gained fame and typically sells out quickly once he opens orders. At present, he utilizes Shopee.

From a business standpoint, it's advisable for him to stay with Shopee. My post is primarily for educational purposes.

Disclaimer: I am not an SRE/DevOps professional, but rather someone eager to share insights that might broaden understanding of web scalability, drawn from my limited experiences. Therefore, there may be inaccuracies, though I hope none too significant.

Expect some odd structuring in the paragraphs, as the content was initially made for Twitter.
