Database Autonomy Service (DAS) is a cloud-based database management service that uses machine learning and accumulated expert knowledge to automate database operations and maintenance (O&M) — from monitoring and self-healing to performance optimization and security protection. DAS reduces reliance on manual operations, keeping your databases stable, secure, and efficient.

Why database O&M is hard
Managing databases at scale involves challenges that grow faster than your team can keep up with.
Database failures during rapid business iteration
Fast-moving development cycles expose databases to a predictable set of problems:
Slow SQL queries emerge during rollouts, degrading user-facing performance.
Database capacity falls short during traffic spikes and promotions.
Schema and index design flaws surface only after deployment.
SQL statements and schema changes go live without proper review.
Troubleshooting and performance optimization
Database troubleshooting is difficult even for experienced teams. Root causes are hard to identify because:
Diagnosis requires large volumes of system and historical data — data that is rarely complete when you need it.
Effective solutions depend on years of hands-on DBA experience, and that experience doesn't transfer easily between teams or business contexts.
Even after identifying a fix, implementation takes time — tuning a database engine, for example, involves iterative code-level changes.
High O&M costs
Cloud environments let you run multiple database types across different deployment contexts, but this flexibility drives up O&M complexity:
Database administrators (DBAs) who are proficient across different database engines are scarce.
Managing heterogeneous databases across environments demands a broad and deep skill set.
O&M knowledge is difficult to systematize and pass on within a team.
Security risks
As the value of your data grows, so does the attack surface. Common risks include:
Unauthorized access and unpredictable or inappropriate use of databases
Data breaches
Data corruption
Hacker attacks
Data exceptions caused by software or hardware bugs
Data loss caused by misoperations
How DAS addresses these challenges
DAS ensures stable, secure, and efficient database services by automating perception, healing, optimization, O&M, and security.
