Cloud Hosting
Cloud hosting distributes a website or application across a pool of virtualized servers in one or more data centers (AWS, Google Cloud, Azure, etc.), enabling on-demand scaling of compute and storage. Domain configuration for cloud hosting typically involves pointing your [[dns-hosting|DNS]] to load balancer IP addresses or [[cdn|CDN]] edge hostnames rather than a single origin server. Because IP addresses can change as infrastructure scales, using CNAME records or Elastic IPs is recommended over hardcoding A records. Many cloud providers also offer managed [[ssl-tls|SSL certificates]] via ACM (AWS) or managed certificate services, simplifying HTTPS setup.
Example
An e-commerce site on AWS points its apex domain example.com to an Application Load Balancer via an ALIAS record, and uses CloudFront (CDN) as a CNAME target for www.example.com, enabling global distribution and auto-scaling.
