• Deploy a web application to the cloud using Elastic Beanstalk

Steps:

1. Access Elastic Beanstalk service from AWS Management Console
   • On the AWS Management Console page, type elastic beanstalk in the Find Services box and then select Elastic Beanstalk.

   • Click the Upload button.
   • Click the Create application button.
     Important: It will take about 10 minutes for your application to be created. There are several resources that need to be spun up to support your application. Your application is created once you see a green check mark and the Health of your application is Ok.
   • After the application is created, copy the application’s URL.
     Important: The URL can be found on the top of the page, to the right of your application’s name.

   • Upon successfully accessing that URL, you will see the text Hello World in your browser window.
3. Inspect the EC2 instance created for you
   • Navigate to the EC2 console and inspect the instance that was created for you. The instance has the same name as your application. You can administer and manage this EC2 as if you created it yourself.
