Edge Security Acceleration (ESA) manages streams of data at points of presence (POPs) by the traffic management features. It controls and optimizes traffic distribution to prevent network congestion, which not only reduces the load on the origin server but also accelerates content distribution and enhances user access experience.
Feature introduction
Feature | Overview |
If your website offers pure dynamic content or a combination of dynamic and static content, such as transactions, gaming, or APIs, the origin server returns differentiated content in response to user requests for dynamic content. However, the communication between users and the origin server may experience delays or failures due to unstable network conditions across borders, regions, or Internet service providers (ISPs). To tackle with this issue, you can enable Smart Routing to monitor the quality of Alibaba Cloud's global POP network in real time and route traffic along the most efficient path. In addition, optimization technologies such as performant protocol stacks are integrated to reduce the global network latency and request failure rate. This boosts user experience and ensures business continuity. | |
Waiting Room allows you to manage excess origin requests to prevent server downtime caused by unmanageable traffic surges. Specifically, you can configure how many users are allowed on your origin and queue excess users in a waiting room. | |
ESA uses the origin pool feature to intelligently distribute and manage traffic at POPs, ensuring even distribution of traffic and optimizing resource utilization. This not only improves service availability and reliability but also enhances overall network performance and user experience. | |
Load balancing distributes traffic among origin servers according to traffic steering policies to reduce latency and improve service availability. |
