##Netflix##

Netflix is the largest provider of streaming content and video-on-demand with 93 million users worldwide. Its path to current success started back in 2015 when Java – the backend technology Netflix used – could not handle such a rapidly growing user base. The backend development could not catch up with the frontend, which caused a higher load time. The customized UI design was unachievable, which led to poor customer experience. Finally, Java took too much time to build, and as a result, the development and deployment processes were inefficiently slow.

The benefits Netflix got:

- Since the adoption of Node.js technology, startup time has drastically decreased by 70%. Instead of taking up ten seconds to load the Netflix interface, it only takes one second now;

- Node.js made it easier to integrate microservices and break a huge block of information into a detailed interface;

- The transition from the backend to the frontend has significantly accelerated due to Node.js being a JavaScript-based environment.

##NASA##

NASA is one of the most well-known enterprises in the world. NASA has decided to make a transition to Node.js after an accident, which almost led to a fatal outcome. The accident was caused by a long access time due to the inefficient storage of data across many locations. NASA’s developers found it important to move data into a cloud database to shorten the access time. Additionally, most of NASA’s applications were built on JavaScript.

The benefits for NASA:

- The access time has increased by 300%, allowing users to reach the information in seconds, not hours;

- NASA has successfully moved legacy databases to the cloud and provided access to them via APIs;

- Node.js has shortened the process of working with databases from 28 steps to only seven, which made scientific research significantly easier.

##Trello##

Trello is a tool for project management, which is used across industries and countries. A platform like this requires instant updates in real-time without latency, which is why Trello is one of the companies that use Node.js for its server-side. Trello needs to juggle several real-time connections on the server to ensure that updates come smoothly and on time.

Trello’s main advantages:

- Node.js provided an extremely lightweight Single Page Application;

- Thanks to Node.js, Trello can handle updates with zero latency;

- Node.js architecture enabled to cut expenses of development and prototyping.

##PayPal Node.js transition##

With over 200 million active accounts, PayPal is a worldwide leader in the industry of online payments and transfers. In 2013, they stumbled upon some difficulties caused by using Java, which didn’t mix well with frontend development. Java provided long development times as well as poor performance, so PayPal has become one of the companies using Node.js.

The benefits PayPal acquired:

- A smaller team of developers built a Node.js based application in a shorter amount of time;

- Response time has reduced, leading to a 35% decrease in loading time;

- The number of user requests per second has doubled since the adoption of Node.js technology.

##LinkedIn##

Another company on the list of the websites using Node.js is LinkedIn — the world’s biggest social media platform built for business and employment networking. Its popularity continues to grow, with 467 million users from more than 200 countries. After shifting from Ruby on Rails to Node.js, they’ve created an application that runs ten times faster than its old version. The decision has been made due to the synchronicity of the previous Ruby App, which led to the long loading times, especially whenever there was a traffic increase.

The benefits LinkedIn obtained:

- The entire LinkedIn architecture has been built on JavaScript, which made the handling of client-server interactions simpler;

- The number of servers has been cut from thirty to three, which doubled the traffic capacity.

##The shift to Node.js — Twitter case##

More than 80% of the account holders on Twitter access it via a smartphone, which led to a decision to build Twitter Lite — an application with minimum functionality that can run even with a poor internet connection. On top of that, the website version of Twitter wasn’t optimized for a slow internet connection. This led Twitter to become one of the companies that use Node.js.

Twitter’s benefits:

- Twitter Lite doesn’t take too much space — 1% to 3% — which saves mobile device users a lot of storage space;

- The application runs even on 3G and 2G connections;

- The maintenance costs of Twitter Lite are significantly lower than of Twitter Desktop.
