The high-level Python web framework Django is well known for its features that are developer-friendly, reliable, and easy to use. It gives developers the ability to swiftly and effectively design web apps.
But when your application becomes more popular and has a wider user base, you may find yourself wondering if Django can manage the volume that comes from 100,000 visits per day.
In this blog, we'll look at Django's performance and scalability features and talk about how to make sure your application can handle that kind of volume of daily users.

Django Basics
Django follows the Model-View-Controller (MVC) pattern, or the Model-View-Template (MVT) pattern. It is designed to encourage clean and maintainable code by separating the application into distinct layers:
- Model: Represents the data and database schema.
- View: Handles user interactions, processes requests, and returns responses.
- Template: Defines how the data is shown to users.
Scalability Issues
When aiming to serve 100,000 daily visits, several scalability challenges need to be addressed:
Database Scalability: Django supports various databases, including PostgreSQL, MySQL, and SQLite. To handle a large number of visitors, you must optimize database queries, use database indexing, and consider database replication or sharding to distribute the load.
Caching: Implementing caching mechanisms can significantly improve performance. Django provides built-in support for caching using various backends like Memcached or Redis. Caching frequently accessed data reduces the load on your application server.
Web Server: While Django has a built-in development server, it’s not suitable for production use. Deploying Django behind a robust web server like Nginx or Apache can help handle a higher number of concurrent requests efficiently.
Load Balancing: As traffic grows, distributing incoming requests among multiple application instances using load balancing becomes necessary. Tools like Gunicorn, uWSGI, or ASGI can help you achieve this.
Horizontal Scaling: To handle a substantial number of daily visits, you might need to scale horizontally by adding more application servers. Container orchestration tools like Docker and Kubernetes can simplify this process.
Asynchronous Processing: Django’s synchronous request-response model can become a bottleneck under heavy load. Utilizing asynchronous programming with libraries like Django Channels or FastAPI can improve concurrency and response times.
Content Delivery: Offloading static assets (images, stylesheets, scripts) to Content Delivery Networks (CDNs) reduces the load on your server and accelerates content delivery to users worldwide.
Monitoring and Optimization: Implement robust monitoring and profiling tools to identify performance bottlenecks and optimize your application accordingly. Tools like New Relic, Datadog, or Prometheus can help with it.
High Traffic Django sites
Several high-traffic websites and applications use Django as their backend framework, these are sites like;
Instagram: One of the most popular social media platforms, Instagram, initially used Django as its web framework. While they’ve since migrated some parts to other technologies, Django played a crucial role in their early growth.
Pinterest: Pinterest, a content-sharing and discovery platform, was built using Django. As the platform scaled, Pinterest engineers have continued to optimize and adapt their Django-based infrastructure.
NASA, DropBox, Disqus, Spotify, Eventbrite, Mozilla, Bitbucket, The Washington Post etcetera.
Conclusion
Django is a powerful web framework that can handle a substantial number of daily visits, even as high as 100,000 or more. However, achieving this level of scalability requires careful planning, optimization, and the use of various performance-enhancing techniques.

At scale it's less about frameworks, more about cloud architecture.
Django is widely used, I don't know why - since there are so many better options for a backend framework, but it is so I guess it does the job.
What are the better options? Can you tell me please? I thought Django was the best option, I am new in web-programming so I don't know.
After researching online, Django seems to be the best option. Other frameworks for handling larger scale would be in "GO" like the "gin" framework, but they dont have many tutorials or community in English, in Chinese they are larger, the others I don't know if they are as fast and "better".
Well, Django seems to be one of the best, mainly because it's an all-rounder and easy to use. The security Django offers is also an attractive feature.
Haha, Django is so straightforward, I guess it's why people use it a lot.
