DAS Managed Services (formerly DAS Economy Edition) builds on DAS Basic Edition with AI-driven database diagnostics and automated maintenance.

How it works

DAS Managed Services integrates the Tongyi Large Language Model (LLM) with the database operations and maintenance (O&M) experience and Standard Operating Procedure (SOP) framework developed by Alibaba Cloud DAS. Each instance receives at least 4 million tokens of intelligent computing power per day, with a current limit of 10 million tokens per day per instance.

DAS Managed Services uses a subscription billing method.
