Cloud Firewall
Alibaba Cloud’s Cloud Firewall serves as the primary defense layer for network security within their compute infrastructure. It is designed to protect resources by filtering incoming and outgoing traffic, acting as a critical barrier against external threats. This service helps organizations maintain visibility and control over their network perimeter, ensuring that only authorized connections reach their cloud-based applications and data stores.
You should choose this solution when you need a straightforward, pay-as-you-go security option without long-term commitments. However, be aware that there is no free tier available for this service. This means you will incur costs from the very first moment of usage, so budget carefully to avoid unexpected charges as your network traffic scales up or down.
