What Is AWS Elastic Beanstalk?
Amazon Web Services (AWS) comprises dozens of services, each of which exposes an area of functionality. While the variety of services offers flexibility for how you want to manage your AWS infrastructure, it can be challenging to figure out which services to use and how to provision them.
With Elastic Beanstalk, you can quickly deploy and manage applications in the AWS Cloud without worrying about the infrastructure that runs those applications. AWS Elastic Beanstalk reduces management complexity without restricting choice or control. You simply upload your application, and Elastic Beanstalk automatically handles the details of capacity provisioning, load balancing, scaling, and application health monitoring. Elastic Beanstalk uses highly reliable and scalable services that are available in the AWS Free Usage Tier.
Elastic Beanstalk supports applications developed in Java, PHP, .NET, Node.js, Python, and Ruby, as well as different container types for each language. A container defines the infrastructure and software stack to be used for a given environment. When you deploy your application, Elastic Beanstalk provisions one or more AWS resources, such as Amazon EC2 instances. The software stack that runs on your Amazon EC2 instances depends on the container type. For example, Elastic Beanstalk supports two container types for Node.js: a 32-bit Amazon Linux image and a 64-bit Amazon Linux image. Each runs a software stack tailored to hosting a Node.js application. You can interact with Elastic Beanstalk by using the AWS Management Console, the AWS Command Line Interface (AWS CLI), or eb, a high-level CLI designed specifically for Elastic Beanstalk
