What is Cloud Computing Architecture?
Cloud computing architecture refers to the combination of components required for cloud services, including front-end platforms, back-end infrastructure, cloud-based delivery, and network systems.
It defines how cloud resources are structured, managed, and delivered over the internet.
- Frontend (client-side interface)
- Backend (servers, storage, databases)
- Cloud delivery models
- Network and virtualization
