Deploying Flask-based Microservices on AWS with ECS Service Connect

Alex — Mon, 30 Dec 2024 00:17:01 +0000

The playlist is broken into six parts:

An introduction to ECS Service Connect and the various AWS components that will be used
Run the flask-based microservice architecture locally before diving into AWS
Get the flask-based microservice architecture **just working** on AWS. We'll rely on a lot of the defaults provided by AWS on the networking to get a working example quickly that you can see in action on AWS
We'll do the same as the previous video, but not rely on default networking setup by AWS. We'll configure networking ourselves with the recommended AWS approach so the app is production-ready
Use GitHub Actions to automate deployments to our flask app code running on our microservice architecture on AWS
Run a CDK (Cloud Development Kit) script that will create both the AWS networking components, as well as the ECS components. After running the script with a single cdk deploy --all\ command, the microservice architecture will be fully functional

End-to-End Tutorial on Combining AWS Lambda, Docker, and Python

Alex — Sat, 09 Jul 2022 14:16:15 +0000

AWS Lambda recently added support for Docker images with Python, where before you had to zip all your code and dependencies. With this update I wanted to make a full length tutorial to cover everything necessary to be productive.

The playlist is broken into six parts:

An introduction to the app that will be built and the various AWS components that will be used
Cloning the GitHub repo and doing necessary setup to test the application locally
Creating a Docker image of the Python script and running it on AWS Lambda, while also showing how painful it is to do even minor updates
Adding CI/CD with GitHub Actions to speed up code updates
Adding AWS Cloudwatch to create a cron job that schedules the Lambda function to run on periodic intervals
Walking through an AWS Cloudformation yaml template that will create the Lambda function and Cloudwatch rule automatically and covering all the benefits of using a Cloudformation template
