How applications are taken online ?

Question

How the online apps are made? is there any language to get the app online ?
What is web application?

Answer 1

Sololearn uses Azure, Microsoft's Cloud solution. It might also run on Docker using Kubernetes, or some other Container Orchestration solution. There is probably a Load Balancer or two in between. All this aside, the concept is the same as you would build any website or app. Once you have it built, you package it and deploy it into the cloud. I don't know about all their instances, but the python playgrounds appear to run a flavor of Ubuntu.

Answer 2

Steven M can we make our own by sql

Answer 3

Yeah, you can make your own SQL server, but you can also use some of the SQL options that are pre built or some of the ready to use software, but you can use other Database options too, like NoSQL, RDS (Relational DB Service), DynamoDB, etc. These DB's are essentially tables ready to use in the cloud. You can also choose to have the DB local on your build, its all up to you and how you want to configure your application.
