What is Oracle Autonomous Database?

Oracle Autonomous Database is a cloud-based database service that handles routine maintenance tasks automatically. It uses machine learning to manage patching, backups, tuning, and security updates without downtime, so your team spends less time on database administration. The service scales compute and storage on demand, making it suitable for organisations that need reliable performance without the overhead of managing infrastructure. You pay only for what you use, and Oracle provides a free tier to get started.
