Big Tech ‌Companies and Their Tech Stacks

Have you ever wondered how‌ big tech companies like Instagram,⁤ Uber, YouTube, Netflix, and WhatsApp‌ were built? What technologies, frameworks, and cloud providers do they ​use? In this video, we will explore the‍ fascinating world of tech stacks used⁣ by these companies.


Uber has managed to break down its application into microservices, which allows for healthy scalability. Initially built in the Python⁤ framework Tornado, Uber decided to keep some parts in ‍Python while rewriting others in Golang for improved speed.​ For the front end, ​Uber uses native apps for Android and Swift for iOS development. ​Their web⁤ app is built using React. ‌In terms of databases, Uber started with Postgres but switched to MySQL⁣ and Cassandra for high availability and speed. As for their cloud provider, Uber is deployed on AWS.


WhatsApp, with its massive user base, has an interesting tech stack. While they haven’t disclosed if ⁤they’ve ⁢moved to React Native, their apps are‍ currently ‍native, ⁢using ⁢Swift for​ iOS and Java‌ for Android. For the backend, WhatsApp uses‌ Erlang-based XMPP⁢ protocol ⁣application server called Ejabberd. Interestingly, WhatsApp ⁢doesn’t store user messages ⁢on their own database; ⁢instead, messages are ⁢stored on users’ phones. This⁣ unique approach provides reassurance in‍ a world where privacy is⁣ a concern.


Instagram, loyal to‌ Facebook, ‍started with native applications but was one ‌of the first companies to ‍adopt ⁢React Native when it launched. Their backend is built using Django, a Python framework, and they have recently transitioned from REST to GraphQL ​for‍ improved performance. Instagram’s database ‍consists of Postgres and Cassandra, with Postgres being used for structured queries ‍and Cassandra for data modeling and recommendation systems. Their servers run on ⁣EC2, and ‍images are stored on S3 buckets.


YouTube, a significant part of Google, has​ never disclosed its front-end technology, leading to speculation that ​it doesn’t use Angular. While the details are scarce, it is ‍likely ​that ​YouTube‌ uses native apps for⁣ both‍ iOS and Android. As for the backend, there is‍ evidence suggesting that YouTube is written in Django or another Python framework. Their database of choice is MySQL, ‍and they rely⁣ on ‌Google Cloud as their cloud‍ provider.


Netflix,‍ known ‍for its successful ⁤transition from free to paid streaming, has a tech stack consisting of React.js for the front end, Flask (a ‍Python framework) for ⁤the backend, and Postgres and Cassandra for their database needs. Like many other⁣ companies,‍ Netflix⁤ relies on AWS as⁢ its cloud⁢ provider.

These⁢ big⁤ tech companies have built their ⁤platforms using a combination of popular frameworks, native apps, and​ cloud providers.⁢ Each company ⁣has made strategic choices to ensure scalability, performance, and ​user⁤ experience. It’s​ fascinating to‍ see how ⁣these companies have evolved and‍ continue to innovate in the ever-changing tech landscape.

  1. Love your spirit. I’m not a tech guy. I’m into business systems. I also run a charity here in the U.K.
    hoping to go start businesses and other ways to create development and employment for young people across Africa next year.
    That’s me in a nutshell.
    Will go through your channel to find out more about your but listening to a sister talking tech, python, django is like listening to a violin – it’s beautiful music to my ears.

    Don’t know why – I just feel so proud. 😀
