A focused secrets service for Alibaba Cloud infrastructure, with rotation and dynamic credentials.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Alibaba Cloud KMS Secret Management is a cloud service for storing, encrypting, retrieving, rotating, and distributing application secrets. It supports generic secrets alongside managed RAM, database, and ECS credentials, making it suited to developers, platform teams, and security administrators managing credentials across Alibaba Cloud applications and infrastructure. Applications can retrieve secrets through Alibaba Cloud SDKs, Secret SDKs, KMS Instance SDKs, or KMS Agent, while web and API access support service administration.
Pricing is paid-only, with a 14-day trial and no free plan. Software Key Management, small specification costs $125 per month when billed annually, with a default secret quota of 0 and additional quota billed separately. Software Key Management costs $500 per month when billed annually and includes a 1,000-key default quota, while Hardware Key Management costs $1,799 per month when billed annually and provides hardware-protected key management. A software pay-as-you-go option costs $4.5 per day with monthly billing; secret usage and QPS usage are billed separately. These structures suit teams that need defined subscription instances or variable usage, but quota and usage charges require careful planning.
The standout capability is its coverage of managed credentials and secret lifecycle controls. Automatic and immediate rotation, dynamic secrets for RAM, RDS, and ECS, staged secret values, and versioning support operational credential management. Integrations span RAM, ApsaraDB RDS, Elastic Compute Service, Container Service for Kubernetes ACK, Function Compute, ActionTrail, Simple Log Service, Terraform, and Resource Orchestration Service. Choose it when Alibaba Cloud alignment, Kubernetes synchronization, and cloud-native audit records are priorities. Organizations seeking a free tier or a platform centered outside the Alibaba Cloud ecosystem should consider alternatives.
