Cloud Firewall

Alibaba Cloud Firewall operates as a pay-as-you-go network security layer, acting as the initial barrier against external threats. It handles traffic filtering and access control directly within the cloud environment, managing inbound and outbound connections to protect infrastructure from unauthorized access or malicious activity without requiring upfront commitments.

This setup suits teams already operating within the Alibaba ecosystem who prioritize flexible billing over fixed contracts. The main drawback is the complete absence of a free tier, meaning even minimal testing or small-scale deployments incur immediate costs. You pay for every unit of protection consumed, which can add up quickly if traffic volumes fluctuate unexpectedly.
