• Benefits: Its comprehensive nature and scalability are ideal for handling millions of concurrent requests.

After getting the information regarding the core of the YouTube infrastructure, let’s talk about video processing. Also, I have explained the delivery techniques this platform implements to provide you with targeted content.

1 – Video Compression Frameworks

Whenever you upload a video on YouTube, it is quickly encoded through compression, encoding, and decoding. Below are the details about frameworks.

a) FFmpeg

• Framework Overview: FFmpeg is an open source tool used for video encoding and decoding.
• Role in YouTube: It ensures videos are optimized for different devices, resolutions, and network speeds.
• Key Features: Video compression, format conversion, and compatibility across codecs like H.264 and VP9.

2 – Content Delivery Network (CDN)

YouTube employs custom built CDN infrastructure to ensure low latency video delivery worldwide.

a) Google Global Cache (GGC)

• Overview: GGC, part of Google’s CDN, caches YouTube’s content closer to users.
• Benefits: Faster video loading times and reduced bandwidth costs.
• Technology Stack: Load balancing, HTTP/2 protocols, and edge servers.

Moving ahead in this blog post on what framework does YouTube use, I have detailed everything in the under section. Have a deep understanding of these details so that you can learn it better.

1 – Data Storage and Management

Data storage and management of the YouTube content is not an easy task as a large number of users share the content on an everyday basis. Google has implemented a sturdy framework for this purpose. The details are below:

a) Bigtable

• Framework Overview: Google Bigtable is a NoSQL database used for massive scale data storage.
• Applications: Storing user preferences, video metadata, and recommendation data.
• Advantages: High throughput and low latency for read/write operations.

b) Spanner

• Framework Overview: Google Spanner is a globally distributed relational database.
• Applications: Managing transactional data and synchronizing user accounts across regions.
• Key Features: Strong consistency and horizontal scaling.

2 – Recommendation System Frameworks

In recent times, all of us have seen wonderful improvements in the recommendation system of YouTube. The primary framework behind this is below:

a) TensorFlow

• Overview: TensorFlow is an open source machine learning framework of Google.
• Role in YouTube: It powers the recommendation engine, which analyzes user behavior to provide personalized video suggestions.
• Techniques Used: Neural networks, collaborative filtering, and content based filtering.

b) Dataflow

• Framework Overview: Google Cloud Dataflow is used for stream and batch data processing.
• Applications: Analyzing user interactions, video performance, and real time trends.
• Key Benefits: Real time insights for improving recommendations and ad targeting.

3 – Security and Scalability Frameworks

Cybersecurity has always been a great challenge for online platforms. That’s why YouTube has implemented a wonderful security and scalability framework to protect its users’ data. The details are below:

a) Kubernetes

• Framework Overview: Kubernetes manages containerized applications across clusters of machines.
• Applications: Ensures high availability and efficient resource utilization.
• Advantages: Automatic scaling, load balancing, and fault tolerance.

b) Borg

• Framework Overview: Borg, an internal Google cluster management system, predated Kubernetes but remains influential.
• Usage: Schedules workloads and manages resources effectively.
• Impact: Enabled the development of Kubernetes and served as a blueprint for modern orchestration tools.

4 – Development and Monitoring Tools

YouTube has been a phenomenal platform so far as it has integrated several development and monitoring tools to maintain the functionality and quality of its content. I have provided a short overview of these tools.

a) Blaze (Bazel)

• Overview: Blaze, an internal build system at Google, was open sourced as Bazel.
• Role in YouTube: Facilitates fast, reliable builds and testing for continuous integration.

b) Stackdriver

• Overview: Google Stackdriver monitors and troubleshoots performance issues.
• Applications: Tracks system health, application logs, and performance metrics.
• Key Features: Alerts, dashboards, and log analysis.

These are the details about what framework does YouTube use. I have performed extensive research and found the elements that are used to maintain the functionality and performance of this video sharing platform. Based on this, I have determined how effectively Google has managed things to deliver exceptional experience to the users. 

From frontend frameworks like AngularJS and Polymer to backend systems powered by Python, Java, and Kubernetes, every aspect of YouTube’s framework is designed to handle scale, speed, and personalization. Owing to them, YouTube has ensured a seamless way of entertainment for millions of users.
