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).ALIBABACLOUD_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).
