How rapid app development is done?

Before cloud comes into IT world, the development was time consuming in terms of deploying,  integrating backend or API to make an end to end functioning application.

But now when you consider AWS, Firebase, Amplify, or Hasura that provides backend service right away with minimal coding or integration efforts. Plus easy deployment from your own. No much coordinated efforts by involving IT Admin team.

So right tool selection is extremely important for the success in delivery and customer service.
