AWS is useful for big business. Automatic multi region failover and hosted databases may be expensive, but they're a massive pain to manually configure and an easy footgun if you're not used to doing that sort of thing. Plus, with Amazon you already have public toolkits to use those features with all of your services, so you don't need to figure how to integrate/what open source system to use to accomplish all of that. Plus, if you go for your own physical server, you need to arrange parts and maintenance windows for any hardware that will eventually fail.

If all you need is "good enough" reliability and basic compute power (which I think is good enough for many businesses, considering AWS isn't exactly outage free either), you're probably better off getting a server or renting one from a cheap cloud host. If you're promising five nines of uptime for some reason, you may want to reconsider.

This is exactly my point. Sorry if I was not clear on my OP.

We are using Seller API to get different product information, while their API provides base work for communicating with their endpoint, you'll have to implement your own system to use that, and handle the absurd unreliability of their API's rate limiter, and the spider web of API callbacks to get information that you require.
