What is the technology stack of Airbnb? originally appeared on Quora, the place to gain and share knowledge, empowering people to learn from others and better understand the world. You can follow Quora on Twitter, Facebook, and Google Plus.

Since Airbnb was launched in 2008, many startups have been trying to repeat the success of a prominent marketplace and it's no wonder why: Airbnb is safe, reliable, user-friendly, and a convenient marketplace that makes it easy to rent and lease accommodations.

That's why I totally understand the interest in Airbnb's tech stack: all those great functionalities and features simply wouldn't be achievable without advanced and efficient technologies.

Let's see what's under Airbnb's hood.

1. Programming languages - Ruby and Javascript.

2. Framework - Ruby on Rails. RoR framework is well known for its awesome capabilities that speed up development and, as a result, reduce costs and TTM (time to market).

3. JavaScript framework - React. A JavaScript UI library, React, is a flexible and efficient solution for building sleek user interfaces.

4. Web server - Nginx. Nginx is a powerful HTTP and proxy server that speeds up content delivery, ensures Airbnb's security and scalability. Not only Airbnb reaps the benefits of Nginx; tech industry giants like Instagram, Netflix, and Zappos use NGinx too.

5. Key-value storage - Redis. Redis provides a scalable cache infrastructure and a key/value database.

6. Cloud storage - Amazon S3, EBS. To store user data including millions of user pictures, Amazon resorts to Amazon services.

7. Cloud hosting - Amazon EC2. Amazon EC2 is an efficient tool that distributes the incoming traffic and doesn't let Airbnb's system go down during sudden traffic spikes or any unexpected traffic fluctuations.

8. Cloud database - Amazon RDS. Amazon keeps its data in an Amazon's cloud relational database. Earlier, Amazon used MySQL databases, but switched to Amazon RDS to simplify administration and other routine tasks.

9. Big Data tools - Presto, Druid, Airpal. Airbnb possesses a tremendous volume of user data, so they use various instruments to store, process, analyze, and manage that data.
