AWS Elastic Beanstalk Functionality For PHP Developers
To deploy PHP applications using AWS Elastic Beanstalk, you simply:
Create your application as you normally would using any editor or IDE. Create an Elastic Beanstalk PHP environment using the AWS Management Console, the command line interface, or the web service APIs. Behind the scenes, Elastic Beanstalk handles the provisioning of a load balancer and Amazon EC2 resources. Install and configure Git for deployments. Commit and push your changes using Git. Elastic Beanstalk deploys your files to one or more Amazon EC2 instances running the Apache HTTP Server. Within a few minutes you will be able to access your application at a customized URL (e.g. http://myapp.elasticbeanstalk.com/).
