A company's gaming application has been gaining popularity. There has been high demand for the gaming application in countries where the company does not currently deploy the application.
Which advantage of the AWS Cloud can help the company to deploy the application to more countries around the world?
Correct : B
The AWS Cloud's global infrastructure enables rapid deployment across multiple geographic regions, allowing companies to extend applications to new markets quickly. This capability to 'go global in minutes' is especially valuable for businesses looking to reach customers in new countries without building data centers. Other options, like speed and agility, are advantages but do not specifically address global deployment.
