AWS (Step-by-Step)

 

1️⃣ Deploying Django on EC2 (Step-by-Step)

Using Amazon EC2, we’ll:

Steps Covered:

  1. Launch Ubuntu EC2 instance

  2. Configure Security Groups (port 22, 80, 443)

  3. Install Python, pip, virtualenv

  4. Setup PostgreSQL (optional local)

  5. Install Nginx + Gunicorn

  6. Configure systemd service

  7. Domain mapping

Production Stack:

Client → Nginx → Gunicorn → Django

You’ll learn:

  • How to avoid common deployment mistakes

  • How to secure your server

  • How to run Django as a background service

2️⃣ Connecting Django to RDS (Managed PostgreSQL)

Instead of hosting PostgreSQL on EC2, we use:

Amazon RDS

Why RDS?

  • Automated backups

  • Multi-AZ failover

  • No manual DB maintenance

  • Read replicas support

What We’ll Cover:

  • Creating RDS PostgreSQL instance

  • Security group configuration

  • Connecting Django using DATABASES setting

  • Handling migrations safely in production

This is how real production systems are built.

3️⃣ Using S3 for Media & Static Files

File uploads don’t belong on EC2.

We’ll use:

Amazon S3

Topics Covered:

  • Creating S3 bucket

  • IAM roles for secure access

  • Configuring django-storages

  • Serving media files securely

  • Static file hosting strategy

This prevents:

  • Lost files during scaling

  • Disk space issues

  • Manual file backups

4️⃣ Celery + Redis on AWS

For background tasks:

  • Email sending

  • Report generation

  • Payment processing

  • Long-running API jobs

We’ll deploy:

  • Celery worker on EC2

  • Redis via Amazon ElastiCache

What You’ll Learn:

  • Running Celery as systemd service

  • Worker scaling strategies

  • Monitoring task failures

  • Retry mechanisms in production

This is critical for scalable APIs.

5️⃣ Dockerizing Django for AWS

Instead of traditional deployment, we move to containers.

We’ll:

  • Write Dockerfile for Django

  • Use docker-compose for local dev

  • Push image to ECR

  • Deploy container to EC2

Optionally, we’ll explore:

  • Amazon ECS

  • Amazon EKS (advanced topic)

Docker + AWS = modern DevOps-ready backend.

6️⃣ CI/CD with GitHub Actions

We’ll automate deployment using:

GitHub Actions

Pipeline Flow:

Push to GitHub →
Run Tests →
Build Docker Image →
Deploy to EC2 →
Restart Services

You’ll learn:

  • Writing workflow YAML

  • SSH deployment

  • Secure secrets handling

  • Zero-downtime deployment basics

7️⃣AWS Architecture Design for Backend Developers

Finally, we’ll design real-world scalable architecture using:

  • Elastic Load Balancing

  • Amazon EC2 Auto Scaling

  • Amazon RDS

  • Amazon S3

  • Amazon CloudWatch

  • Amazon Route 53

We’ll design:

High-Traffic REST API Architecture

Database Integration in FastAPI (SQLAlchemy CRUD)

  Introduction So far, we’ve built APIs without storing data.But real-world applications need a database to: Store user data. Manage products. Persist application state. In this blog, we’ll connect FastAPI with a database using SQLAlchemy and perform CRUD operations . What is SQLAlchemy? SQLAlchemy is a powerful Python ORM (Object Relational Mapper) that allows you to: Interact with databases using Python code. Avoid writing raw SQL queries. Work with models instead of tables. Step 1: Install Dependencies pip install sqlalchemy (For SQLite, no extra driver needed) Project Structure Update app/ ├── main.py ├── database/ │ ├── connection.py ├── models/ │ ├── item.py ├── schemas/ │ ├── item.py ├── routes/ │ ├── item.py Step 2: Database Connection app/database/connection.py from sqlalchemy import create_engine from sqlalchemy . orm import sessionmaker , declarative_base DATABASE_URL = "sqlite:///./test.db" engine = create_engine ( DAT...

Middleware & CORS in FastAPI

  Introduction As your API grows, you may need to: Log requests Modify responses Handle cross-origin requests This is where Middleware and CORS (Cross-Origin Resource Sharing) come into play.They help control how requests and responses flow through your application. What is Middleware? Middleware is a function that runs: Before a request reaches your route After a response is returned Think of it as a pipeline layer between client and server. Request Flow with Middleware Client → Middleware → Route → Middleware → Response Creating Custom Middleware from fastapi import FastAPI , Request import time app = FastAPI () @ app . middleware ( "http" ) async def log_requests ( request : Request , call_next ): start_time = time . time() response = await call_next ( request ) process_time = time . time() - start_time print ( f"Request: { request . url} | Time: { process_time } " ) return response What This Middle...

Python Data Handling

Python Data Handling for Beginners In Python, data handling means storing, changing, and using data in different ways. In this post, you will learn: Lists Tuples Dictionaries Sets String Methods Type Conversion 1. Python Lists :Lists store many values in one variable.                fruits = ["apple", "banana", "mango"]                                                                       Method                          Use                                            append()          ...
