What is the primary purpose of Anti-DDoS Basic on Alibaba Cloud?

The primary purpose of Anti-DDoS Basic on Alibaba Cloud is to automatically scrub traffic up to a basic threshold. This service is designed to protect resources from Distributed Denial-of-Service (DDoS) attacks by filtering out malicious traffic before it can reach the customer’s application servers.

When a DDoS attack is initiated, the Anti-DDoS Basic service automatically detects the unusual traffic patterns associated with such attacks and intervenes by blocking or cleaning the malicious traffic. This automatic scrubbing ensures that legitimate traffic can still access the server while the attack is underway, thereby maintaining the availability and performance of the application. The basic threshold refers to the maximum capacity of traffic that can be treated by this service before needing to upgrade to more advanced protections.

While other options may describe features that relate to security measures, they do not capture the primary function of the Anti-DDoS Basic service. Advanced attack visualization features, customizable security policies, and resource monitoring and alert management are more relevant to other security services or more advanced tiers of DDoS protection, rather than the core automatic traffic scrubbing functionality provided by Anti-DDoS Basic.
