Cloud Computing

Cloud computing is the delivery of computing resources—including servers, databases, Software, and storage—over the internet on a pay-as-you-go basis, rather than owning physical infrastructure. Instead of running applications on local machines, users access them remotely from data centers maintained by providers like Amazon Web Services, Microsoft Azure, or Google Cloud.

This model revolutionized how organizations scale operations. Need more processing power at midnight? Spin it up instantly. No longer need it? Shut it down and stop paying. It democratized access to enterprise-grade infrastructure, letting startups compete with established firms without massive upfront capital costs.

Cloud computing powers everything from streaming video to AI training to scientific modeling. It introduces fascinating challenges: security across shared systems, latency concerns for real-time applications, and profound questions about data sovereignty and privacy.

The shift from "owning" to "renting" computing mirrors broader economic trends, and its environmental impact—consolidating power consumption in efficient data centers—remains hotly debated.
