Using API calls directly

If your cloud provider offers an API accessible in your language of choice, you can interact with the cloud resources directly from your application.

Example: you have an application that allows users to upload their own pictures. This application uses the Cloud API to create a storage bucket for each newly registered user:

#include <aws/core/Aws.h>

bool create_user_bucket(const std::string &username) {
  Aws::S3::Model::CreateBucketRequest request;

  Aws::String bucket_name("userbucket_" + username);
  request.SetBucket(bucket_name);

  Aws::S3::Model::CreateBucketConfiguration bucket_config;
  bucket_config.SetLocationConstraint(region);
  request.SetCreateBucketConfiguration(bucket_config);
