NGINX
NGINX (pronounced "engine-x") is like a highly efficient traffic director for websites and web applications. When people visit a website, NGINX helps manage all these visits smoothly, making sure the website stays fast and reliable even when many people are using it at once. It's similar to having a smart receptionist who knows exactly how to direct visitors to the right place without creating bottlenecks. Companies use NGINX because it helps their websites run faster and handle more visitors without crashing. It's often mentioned alongside other web servers like Apache, but NGINX is known for being particularly good at handling lots of visitors at the same time.
