The Evolution of Cloud Server Technology and Its Strategic Business Impact

In the digital economy era, cloud servers have become the backbone infrastructure supporting global enterprise operations. This white paper provides an in-depth exploration of cloud server functionalities, technical specifications, and real-world applications. We will examine 15 distinct use cases across industries, analyze cost-benefit ratios through case studies, and project future technological developments up to 2030.

Core Infrastructure Services Cloud servers deliver on-demand computing power through three primary service models: IaaS (Infrastructure as a Service): Amazon EC2, Microsoft Azure VMs, Alibaba Cloud ECS paas (Platform as a Service): Heroku, Google App Engine, IBM Cloud Foundry FaaS (Function as a Service): AWS Lambda, Google Cloud Functions

Key technical specifications include:
