Building a JSON REST API with Python and Flask: Part 4

In this article, we will cover the deployment of our Flask application to AWS Elastic Beanstalk. AWS Elastic Beanstalk is a platform as a service (PaaS) that allows you to easily deploy and manage applications in the AWS cloud.

Setting up AWS Elastic Beanstalk

Before we can deploy our Flask application to AWS Elastic Beanstalk, we need to set up our environment. First, make sure you have an AWS account and have the AWS Command Line Interface (CLI) installed and configured on your local machine.

Once you have your AWS account and CLI set up, you can create a new Elastic Beanstalk environment using the AWS Management Console or the AWS CLI. You will need to specify the platform, application name, and environment name. For our Flask application, we will choose the Python platform.

Creating a Deployment Package

Before we can deploy our Flask application to AWS Elastic Beanstalk, we need to create a deployment package containing our application code, dependencies, and configuration files. This can be done using the eb cli tool or by creating a .zip file containing all the necessary files.

Make sure to include a requirements.txt file containing all the Python packages required by your application. You can create this file using the pip freeze command or by manually listing the dependencies.

Deploying to AWS Elastic Beanstalk

Once you have your deployment package ready, you can deploy your Flask application to AWS Elastic Beanstalk using the eb cli tool or the AWS Management Console. The deployment process will create a new environment and deploy your application code, dependencies, and configuration files to the AWS cloud.

After the deployment is complete, you will be able to access your Flask application using the URL provided by AWS Elastic Beanstalk. You can also configure the environment settings, monitor the application, and perform rolling updates using the AWS Management Console or the eb cli tool.

Conclusion

Deploying a Flask application to AWS Elastic Beanstalk is a simple and efficient way to host your REST API in the cloud. By following the steps in this article, you can easily deploy your Python and Flask application to AWS and make it available to users around the world.
