Python programming is being used throughout the digital ecosystem. It is one of the most widely used languages for data science, web development, machine learning, and DevOps.Netflix is one of the companies that is using python programming in almost every aspect of their work. Python is used by Netflix throughout the content lifecycle. We’ll explore various Python programming uses at Netflix in this article.

What Programming Language does Netflix use?

Python programming language is used by Netflix for the majority of its activities, however not all of them can be carried out in a single language. Netflix uses a variety of other languages to make numerous tasks more efficient. Many of Netflix’s back-end operations are carried out using Java and Scala. Its online application was created using JavaScript. Node.js, React, MySQL, PostgreSQL, Amazon RDS, Presto, CloudBees, Pig, Amazon EC2, Amazon S3, Cassandra, and other programming languages and technologies are also used by Netflix.

How Netflix Is Using Python Programming

Python is used by Netflix for practically all of its content lifecycle operations. Netflix employs the Python programming language for everything from recommendation engines to security management, and statistical analysis to vulnerability detection.

Managing Machine Learning Projects

Netflix uses machine learning in many tasks across the verticals. It executes its machine learning projects from the prototype stage to production using the Python framework named Metaflow. To manage millions of data points in memory and distribute the work across thousands of CPUs, Metaflow uses parallel programming and efficient Python programs.

Statistical Analysis Tasks

Python is used by the Netflix CORE team for statistical analysis jobs. To automate the processing of signals received at alerting systems, they employ various mathematical and statistical libraries, including Numpy, Scipy, Pandas, and Ruptures. A time series correlation system has also been created by Netflix to parallelize massive amounts of data analysis work.

Demand Engineering and Resource Distribution

The Netflix cloud’s capacity operations, regional fail-overs, traffic distribution, and fleet efficiency are all handled via demand engineering. Python programming is used to create the demand engineering tools used by Netflix, together with libraries like Numpy, Scipy, boto3, RQ, and Flask APIs.

Security 

Python programming is used by Netflix’s information security team to carry out tasks including risk classification, vulnerability detection, and security automation to achieve a variety of high leverage objectives. Python programming has been used to create open source applications like Security Monkey and Prism that carry out various information security-related activities.

Content Recommendation

In developing its machine learning infrastructure for personalization, Netflix heavily relies on Python. To simplify tasks like movie recommendation, they make extensive use of python frameworks including TensorFlow, Keras, PyTorch, XGBoost, and LightGBM along with Numpy, Scipy, Sklearn, Matplotlib, pandas, and CVXPY.

Content Delivery

Netflix’s content delivery network is named Open Connect. The majority of the software used to plan, construct, and run the network is written in Python. A bulk of Netflix’s network devices are controlled by Python-programmed apps.

Big Data Management 

The Netflix big data orchestration team is in charge of supplying the scheduling and execution tools for ETL and Adhoc pipelines. Python programming is used by a number of elements of Netflix’s orchestration service. As an illustration, the scheduler uses papermill and Jupyter notebooks to give job kinds in templates. Their users benefit from having a consistent and simple manner to convey the tasks that need to be completed.

Experimentation 

The engineers working in Netflix’s scientific computing department are building a platform for analysing AB tests and other experiments. Netflix Engineers have created a framework that allows contributors to create reusable SQL searches that take parameters using Metrics Repo, which is based on PyPika. For any new analysis, this tool acts as a starting point.

Netflix employs the Causal Models library, which was created using the Python and R programming languages, to create new models for causal inference. Netflix use PyArrow and RPy2 for statistical computations. Plotly serves as the foundation for the Netflix Visualizations library. They can produce products that are in line with their platforms thanks to it.

Video Encoding 

Python is used by Netflix in projects like VMAF and mezzFS. Python programming has been used by Netflix to create computer vision applications utilising the media map-reduce platform Archer. For the creation of projects like Pickley and Setupmeta, Netflix has also hired outside developers to create tools in Python.

Animation

All of the industry-standard animation and VFX material on Netflix is produced by engineers using Python programming. Python is used to implement Netflix’s integrations with Nuke and Maya, and the majority of the shotgun tools within Netflix are also written in Python.

Monitoring, Alerting, and auto-remediation 

The diagnostics, alerting, operational insight, and auto-remediation tools of Netflix are created and maintained by the insight engineers. They are recording dimensional time series measurements using the Spectator Python Client Library. In order to communicate with various platform-level services, Netflix engineers have also created a number of python libraries.

Notebooks 

Jupyter notebooks are used a lot by Netflix engineers. Python is their main language of choice for creating, exploring, and prototyping various jobs. Engineers at Netflix have created specialised Jupyter server extensions that enable them to handle various activities like logging, publishing, cloning, and archiving notebooks.
