# Simple Application Server (SWAS-OPEN 2020-06-01)

Use SWAS-OPEN OpenAPI to manage full SAS resources: instances, disks, snapshots, images, key pairs, firewall, Cloud Assistant, monitoring, tags, and lightweight databases.

## Prerequisites

- Prepare AccessKey with least-privilege RAM user/role.
- Choose correct region and matching endpoint (public/VPC).`ALICLOUD_REGION_ID` can be used as default region; if unset choose the most reasonable region, ask user if unclear.
- This OpenAPI uses RPC signing; prefer Python SDK or OpenAPI Explorer instead of manual signing.

## SDK Priority

1) Python SDK (preferred)
2) OpenAPI Explorer
3) Other SDKs

### Python SDK quick query (instance ID / IP / plan)

Virtual environment is recommended (avoid PEP 668 system install restrictions).
