+You you can upload/write your Flask app and fire it up using gunicorn, but here I will showcase an example using the hello world app - refer https://flask.palletsprojects.com/en/2.3.x/quickstart/
+Below code is saved to hello.py
+<code>
+from flask import Flask
+app = Flask(__name__)
+@app.route("/")
+def hello_world():
+    return "<p>Hello, World!</p>"
+</code>
+Now to fire our flash app, we use gunicorn
+<code>
+gunicorn -b 0.0.0.0:8000 -w 4 --forwarded-allow-ips='172.16.26.1' hello:app
+</code>
+To run it in background, we append & to the above command
+<code>
+gunicorn -b 0.0.0.0:8000 -w 4 --forwarded-allow-ips='172.16.26.1' hello:app &
+</code>
+To exit virtual environment use the command
+<code>
+deactivate
+</code>
+**Django**
+<code>
+mkdir django-project
+cd django-project
+python3 -m venv .venv
+source .venv/bin/activate
+</code>
+Running the last command with activate the virtual environment, proceeding further
+<code>
+pip install django
+pip install gunicorn
+</code>
+Here we can refer to https://docs.djangoproject.com/en/5.1/intro/tutorial01/ to run a hello world Django application
+<code>
+django-admin startproject mysite
+cd mysite
+</code>
+When you change into //mysite// folder, it contains //manage.py// along with a //mysite// child folder
+W.r.t. Django, please refer to these important links \\
+* https://docs.djangoproject.com/en/1.10/ref/settings/#allowed-hosts - Please add your VHost name as mentioned in the linked article \\
+* https://docs.djangoproject.com/en/3.0/ref/settings/#secure-proxy-ssl-header - Tt concerns the prefixing of http or https to your URLs/Assets
+Now to fire our Django app, we use gunicorn
+<code>
+gunicorn -b 0.0.0.0:8000 -w 4 --forwarded-allow-ips='172.16.26.1' mysite.wsgi
+</code>
+To run it in background, we append & to the above command
+<code>
+gunicorn -b 0.0.0.0:8000 -w 4 --forwarded-allow-ips='172.16.26.1' mysite.wsgi &
+</code>
+To exit virtual environment use the command
+<code>
+deactivate
+</code>
+**Generic Python App**
+<code>
+mkdir generic-project
+cd geneic-project
+python3 -m venv .venv
+source .venv/bin/activate
+</code>
+Running the last command with activate the virtual environment, proceeding further
+<code>
+pip install gunicorn
+</code>
+Here is a small hello world example of our generic app
+Below code is saved to hello.py
+<code>
+def app(environ, start_response):
+    data = b"Hello, World!\n"
+    start_response("200 OK", [
+        ("Content-Type", "text/plain"),
+        ("Content-Length", str(len(data)))
+    ])
+    return iter([data])
+</code>
+Now to fire our flash app, we use gunicorn
+<code>
+gunicorn -b 0.0.0.0:8000 -w 4 --forwarded-allow-ips='172.16.26.1' hello:app
+</code>
+To run it in background, we append & to the above command
+<code>
+gunicorn -b 0.0.0.0:8000 -w 4 --forwarded-allow-ips='172.16.26.1' hello:app &
+</code>
+To exit virtual environment use the command
+<code>
+deactivate
