Cloud Services
Cloud computing replaces physical on-premise hardware with scalable virtual computing resources over the web.
Definition for Exam:
Cloud Services refer to computing infrastructure, storage, databases, and software applications delivered on-demand over the Internet on a pay-as-you-go model.
Cloud Service Models:
- IaaS (Infrastructure as a Service): Renting basic virtual servers and storage space (e.g., AWS EC2).
- PaaS (Platform as a Service): Renting development environments to build and host apps (e.g., Google App Engine).
- SaaS (Software as a Service): Renting ready-to-use software over the web browser (e.g., Google Docs, Office 365).
