1. Instagram

Overview

Instagram is a famous American photo and video-sharing social media service. Users of this app can upload photos and videos, write text, and modify videos and images using different filters. They can also communicate with each other, share content, and conduct streaming videos. Instagram started to gain popularity in 2010. Then, Facebook (Meta) bought this platform for $1 billion in April 2012. Six years later, the purchased app reached the 1 billion user mark. As of 2024, 2.4 million people have become Instagram users.

Python Usage:

The backend part of Instagram was built using Django, a framework still used by Meta’s software engineers. The social media platform uses Python to manage content and ensure data integrity. Instagram also leverages Python’s support of such functionalities as data analysis, machine learning, and web server interactions. Developers praise Python for its simplicity, extensive library, rapid development, and source code evaluation, which all result in quicker updates and deployment.

Features:

  • Data handling: Python assists in managing content and providing data integrity;
  • API integration: Developers use Python for seamless API integration; 
  • Type checker: An open-source static type checker called Pyre is used for server application examination and streamlining programmers’ efficiency;
  • Code analysis: LibCST was created by Instagram software engineers for code analysis, evaluation, and refactoring. 

Impact:

Instagram’s choice to modify Python’s garbage collection resulted in a 10% boost in efficiency. While a 10% increase may seem minor, at Instagram’s large scale, it leads to a notable decrease in resource consumption and infrastructure expenses.

Instagram is continuously extending further. The company’s developers harness Django to adjust this well-known web service and maximize its efficiency.

As Spotify declares, Python is primarily utilized in two areas: backend services and data analysis. The backend at Spotify comprises numerous interconnected services that communicate using a custom messaging protocol over ZeroMQ.

Performance is a key priority for Spotify. Python aligns well with this goal, as it enables significant improvements in development speed. They also extensively utilize Python’s async frameworks to support IO-bound services. Some services require intensive computation, and they’ve explored various approaches to manage this in Python, including performance testing, profiling, cython, and the use of native libraries.

Features:

  • Data processing: Spotify developers harness the Python-based tool Luigi for scalable and structured data processing;
  • Data analysis: Spotify uses Hadoop, created with Python, to analyze the music preferences of users; 
  • Music recommendations: Hadoop and Luigi packages offer individual recommendations of music content for each user based on their preferences;
  • Messaging protocol: The music streaming platform has created several connected services integrated through ZeroMQ, a universal open-source messaging Python library.

Impact:

Spotify is a leading music streaming service worldwide. Most of its success happened because of utilizing Python, which developers use to create various features. Python-based tools power music recommendations, data analysis, and server-side services. The Python programming language is a readable, simple, and accessible tool that assists in creating scalable Spotify services, enabling seamless data processing, machine learning, and data analysis.

So, the next time you see a Spotify recommendation, you will know that this advice is based on the source code created with the help of Python.
