Hosting applications and websites on virtual servers in the cloud rather than on a single physical server.
Cloud hosting platforms like Amazon Web Services (AWS) and Google Cloud Platform (GCP) provide scalable, highly available infrastructure for modern applications. Instead of buying a physical server that can crash if too many users visit your app, cloud hosting automatically scales up processing power when traffic spikes, and scales down to save you money when traffic is low. Proper cloud infrastructure is vital for ensuring your app never goes offline during a massive marketing push.
