Unlock the Power of AWS App Mesh and Flask: Build Resilient and Scalable Cloud Native Microservices!

AWS App Mesh is a service mesh that makes it simple to control and monitor AWS-based microservices. You can quickly and easily set up a network of microservices and learn about how they communicate with each other by using App Mesh. I’ll show you how to use AWS App Mesh to build a basic Python Flask application in this article.

Step 1: Create a Docker container

The first step is to create a Docker container for your app. For this example, I’ll create a simple Flask app that responds to HTTP requests.

Create a new file named Dockerfile in your project directory and add the following content:

FROM python:3.8 
WORKDIR /app 
COPY requirements.txt ./ 
RUN pip install -r requirements.txt 
COPY . . 
CMD [ "python", "./app.py" ]

This Dockerfile starts with the official Python 3.8 image, sets the working directory to /app, copies the requirements.txt file, installs the dependencies using pip, and copies the app code.

Create a requirements.txt file with the following content:

Flask==1.1.2

This file specifies the Flask dependency that will be installed by pip.

Step 2: Write the Flask app

Create a new file named app.py in your project directory and add the following content:

from flask import 
Flask…
