Recently, Microsoft has really embraced NodeJS. They thoroughly support Node on the Azure cloud platform. Its one of Azure’s major features, and they’ve integrated Visual Studio support for Node.
Microsoft has also developed a version of Node for Internet Of Things(IoT) applications. NodeJS is great of IoT because it’s light weight and efficient.
The online payment giant was one of the earliest adopters of NodeJS. During an overhaul of their account overview page, they decided to try building the page in Node at the same time as their usual Java development. The NodeJS version worked out so well, that they chose to use it in production and build all client-facing applications in Node going forward. That means that most of what you see in your account is running on Node.
Like PayPal, Netflix started out using Java for just about everything. They too ran into problems with Java’s size and the time it required to develop.
Over time, Netflix moved away from its more traditional structure into the cloud and started to introduce NodeJS. With Node, Netflix was able to break down pieces of their user interface into individual services. This more distributed approach was able to speed things up an alleviate stress on their servers. Today, a large portion of Netflix’s interface is running on Node.
Groupon used to be infamously slow. Why? They were powered by Ruby on Rails. That’s the same framework that brought you the Twitter fail whale.
Groupon was all one gigantic Ruby on Rails application. Thanks to difficulties in speed and maintainability, they decided to change over to NodeJS. Node allowed Groupon to rebuild their entire US website by breaking down everything into individual NodeJS web applications. Now, Groupon is made up of over 20 Node applications, and it moves much faster as a whole.
Groupon is currently moving all of their international sites to NodeJS and has joined the NodeJS Foundation. It’s pretty clear that they are happy with their change.
Uber needs to handle loads of data in real time. They have millions of requests coming in continuously, and that’s not just hits on a page. Uber needs to track driver locations, rider locations, and incoming ride requests. It has to seamlessly sort that data and match riders as fast as possible.
It doesn’t stop there. Facebook created React, one of the most popular front end frameworks. Facebook uses React on Facebook.com as well as Instagram and WhatsApp.
eBay’s story is a lot like Netflix’s. For a long time, just about everything in eBay’s tech stack was based on Java. A few years ago, eBay encountered a problem that Java wasn’t the right solution for. They decided to give NodeJS a shot instead.
Node worked so well that eBay not only kept using it for that particular service, they began migrating their entire user facing stack to NodeJS. Now, just about everything that you interact with on eBay is powered by Node. Sure, beneath Node, Java is still dealing with their databases, but eBay still places a lot of trust in NodeJS.
Most people probably don’t think of Walmart as a tech company, but because they’re one of the largest retailers in the world, their online retail business is gigantic. It’s not much of a stretch to see how they need build a technologically advanced web application do drive their online business.
Walmart started out with Java. It’s a solid enterprise-grade platform that has been the de facto choice for years. However, Walmart needed something faster and lighter weight for their mobile site. So, they turned to NodeJS.
Once again, Walmart began to see Node as a valid Java replacement in loads of other places. Today, the Walmart.com that you see is powered by Node. NodeJS was also the ideal choice for other web applications within their marketplace that require multiple users to be able to access management interfaces simultaneously.
LinkedIn relies on NodeJS for its mobile site. A few years back, LinkedIn used Rails for its mobile site. As with other other large Rails applications, it was slow, monolithic, and it scaled poorly.
LinkedIn switched over to NodeJS to solve its scaling problems. Node’s asynchronous capabilities allowed the LinkedIn mobile site to perform more quickly than before while using fewer resources. Node also made data sharing and building APIs easier for the LinkedIn developers.
