Node.js Foundation takes pride in its security process, as per foundation community manager Mikeal Rogers, as it has one of the most secure out-of-the-box SSL configurations. “We were one of the first open source projects that went through and passed the Core Infrastructure Initiatives best-practices badges program from the Linux Foundation,” adds Rogers.
Our team of Node.js specialists states that every single operation executed in Node.js is a series of asynchronous callback, hence it runs on a single thread, unlike other web technologies where a new thread is prompted for every single client request. This basic event-driven architecture used by Node.js not only makes it lightweight but also lays the base for Node’s typical non-blocking I/O feature.
The servers of retail giant WalMart did not go over one percent CPU utilization on Black Friday, the busiest shopping time of the year, with more than 20 million users deployed online when they put all their mobile-based traffic through Node.js. The global networking site, LinkedIn shifted from Ruby to Node.js in order to handle their mobile traffic and also reduced their number of servers by almost 90 percent, i.e. 30 to 3. The speed of their new system increased 20 times and this is a clear indication of the performance capability of Node.js.
