How have you implemented server-side deployment in your previous projects?

For deploying the server-side in Python projects, I used several approaches depending on the requirements and infrastructure:

• Docker: Created a Dockerfile for containerizing the application, which simplified deployment and scaling. For example, used a Python image, copied the code, installed dependencies, and started the server.

FROM python:3.9-slim
WORKDIR /app
COPY requirements.txt ./
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "app.py"]

• Virtual environments and system services: On Linux servers, I created a virtual environment, installed dependencies, and configured a systemd service for automatic start and restart of the application.

• PaaS platforms: Used Heroku, AWS Elastic Beanstalk, or DigitalOcean App Platform for quick deployment without deep infrastructure management.

• CI/CD: Set up automatic deployment via GitHub Actions or GitLab CI, so that pushing to the main branch automatically triggered the build and deployment process.

The choice of method depends on the project scale, fault tolerance requirements, and available resources.
