Server Load Balancer SSL termination and Certificate Management Service provide the most direct combination for centralized TLS protection and certificate lifecycle management.
With SSL/TLS termination on the load-balancing layer, clients establish encrypted HTTPS or SSL connections to the SLB service. Encryption processing is performed centrally rather than requiring every backend instance to independently process incoming TLS handshakes. This simplifies the backend architecture and centralizes certificate configuration.
Certificate Management Service is specifically designed for issuing, importing, storing, monitoring, deploying, and renewing SSL certificates. Alibaba Cloud currently supports centralized certificate deployment to services including SLB, CDN, WAF, ECS, and other supported resources.
The integration is particularly strong because Alibaba Cloud ' s load-balancing services use certificates managed through Certificate Management Service. For example, SSL listeners require appropriate server certificates for encrypted client connections.
WAF adds web-application threat protection but is not primarily a certificate lifecycle automation solution. CDN with HTTPS is valuable for accelerated content delivery but is not required simply to centralize TLS termination. KMS protects cryptographic keys and secrets but does not replace SSL certificate deployment and lifecycle management.
Therefore, SLB plus Certificate Management Service provides encrypted access and centralized certificate administration with the lowest operational burden.
