Online Systems
Online systems refer to software applications or platforms that operate over the internet, enabling users to access services, data, and functionality remotely through web browsers or client applications. They typically involve client-server architectures, real-time data processing, and cloud-based infrastructure to deliver scalable and accessible solutions. Examples include e-commerce websites, social media platforms, online banking systems, and SaaS (Software as a Service) products.
Developers should learn about online systems to build modern, internet-enabled applications that serve global users with high availability and scalability. This is essential for creating web applications, mobile apps with backend services, and cloud-based solutions where real-time interaction and data access are required. Mastery of online systems is crucial for roles in full-stack development, DevOps, and cloud engineering, as it underpins most contemporary software delivery.
