What cloud service does DevRant use?

Aws Or Azure?
And how much do you pay a month for maintenance costs?

What tables to store data? MongoDB, dynamoDB, oracle?
Or S3 streams?

Just wondering.

As an Angular developer, i am thinking switching to React, major companies and websites are using it
React:
Facebook,Twitter Instagram,Dropbox,Aws,New outlook,mongodb cloud, Amazon drive,Udemy, ....

Angularjs
Gcloud, not many more

Angular 2+
???????

Is the switch advisable?

Amazon just launched DocumentDB, a clone of MongoDB.
I personally waited for this for a long time. How about you?

Can someone explain me how prisma ORM works? I just finished a course with nextjs that uses prisma. Prisma basiclly performed all crud operations on mongodb for example. I saw no usage or need for cloud providers (aws). No backend separation. Like literally all of it was done in fucking nextjs. Very efficiently coded but still how is this good? Please explain why not built a separate backend. Why do it like this
