Description: Application performance in the context of DDoS (Distributed Denial of Service) protection refers to the ability of applications to maintain their functionality and performance despite being targeted by attacks designed to saturate their resources. A DDoS attack involves multiple compromised systems sending massive traffic to a server, which can result in service disruption or a noticeable decrease in response speed. To mitigate these effects, applications must implement defense strategies that include identifying and filtering malicious traffic, as well as distributing the load through content delivery networks (CDNs) and other resilient architectures. The importance of good performance in this context lies in the need to ensure service availability and continuity, especially for businesses that rely on their online presence. Optimal performance not only protects infrastructure but also preserves user trust and brand reputation. DDoS protection solutions may include web application firewalls, intrusion detection systems, and cloud mitigation services, all designed to ensure that applications continue to operate effectively even under adverse conditions.
