Flask Blog

Introduction

This FlaskBlog web application is simply built with the micro-web framework Flask, HTML and the CSS framework Bootstrap. Different features in this application such as user authentication and password reset via email was all made possible with the aid of the available functionalities in flask such as Flask-WTF, Flask-Login, Flask-Mail etc.

Deployment

The web application has been deployed on AWS to EC2 instances set up in an autoscaling group in different AZs (Availability Zones), with an Application Load Balancer attached to a target group containing the EC2 instances. Here is the URL to access the web application link.

Before each EC2 instance was created and configured to serve the web application:

• An AMI image was created. This AMI image contains the dependencies that the Flask application would require. Such as Nginx, Gunicorn etc.

• A launch template was created as well specifying the type of instances to be created and deployed using the AMI image created above.

• An autoscaling group was created with the launch template included.

• A security group was created in the default VPC. Different ports were exposed to allow access for the different protocols (HTTP, TCP and HTTPS).

• A target group was created and the two instances created with the launch template were included in the registered templates.

• An Application Load Balancer was created and linked to the target group and the listeners for each protocol (HTTP and HTTPS) were setup with the necessary security policy and SSL certificate.

• A free public SSL certificate was acquired from the ACM (Amazon Certificate Manager).

• A domain name was acquired from Namecheap and added to Hosted Zones in Route 53.

• Custom Domain Name Servers were created on Namecheap and the AWS NS record was copied and added as part of the Custom Domain Name Servers.

• CNAME records and A records were created on Route 53 for proper routing from the load balancer to the purchased domain.
