Cloud Computing Foundations: Compute, Storage, Networking and Permissions
A Chinese-language ZIP guide to cloud resource relationships, object storage, virtual networks, identities and least-privilege access.
What this cloud guide covers
This Chinese-language ZIP introduces cloud computing through four connected layers: compute, storage, networking and identity or permissions. It helps learners reason about the path from an application to data, the resource boundary, the cost or lifecycle boundary and the account allowed to perform each action.
The English page is a searchable summary and file guide. Cloud product names, consoles, quotas, billing rules and regional availability change, so current provider documentation and account policy remain the source for live decisions.
A resource-map workflow
Draw the application, data flow, network entry and identity path first. Compare resource types by purpose, lifecycle and cost, then split permissions into read, write and administration and validate with a low-privilege test account.
File and scope note
The indexed file is a 77.34 KB ZIP. It is an introductory reference; retain the version date and verify current platform behavior before applying an example. Content review date: 2026-08-23.

Cloud resource and permission study guide
Map application, data, network and identity layers, then validate a small cloud scenario with temporary low-privilege access.
Before you start
- Have a ZIP extractor and a diagram for cloud resource relationships.
- Understand servers, file storage, network addresses and user accounts.
- Use an isolated account and low-privilege resources rather than production data.
Quick start
- 01
Draw the four layers
Mark compute, storage, networking and identity, then draw the direction an application takes to reach data.
- 02
Compare resource types
Record purpose, lifecycle, availability boundary, cost dimension and common misuse for each resource.
- 03
Design least privilege
Separate read, write and administration actions, name the resource scope and identify the principal for each action.
- 04
Run a configuration review
Use a simulated scenario to check network entry, data access, logging and cleanup, linking each setting to a risk and test.
Usage tips
- Record resource and billing boundaries beside the service name instead of memorizing product labels alone.
- Use temporary read-only access first, then remove test resources and permissions after the exercise.
- Keep platform, region, quota and pricing assumptions dated because they change.
Troubleshooting and uninstall
Resources can reach the network but the application still fails. What should I compare?
Check network segment, route, port and security policy first, then identity permission and application configuration.
A policy is broader than needed. How should it be narrowed?
Record actual actions, replace wildcard resources and actions with named objects, and verify read-only access before adding writes.
Frequently asked questions
What is the recommended starting point for cloud computing?
Draw the application, network, storage and identity relationship, then study one complete scenario instead of memorizing a service list.
How do object storage and an instance disk differ?
Object storage manages files as objects through an interface, while an instance disk usually provides block-device semantics tied to a compute lifecycle.
Why does least privilege matter in cloud practice?
It limits the impact of a mistake or leaked credential and makes actual access easier to audit and revoke.
