You can manage Dynamic Content Delivery Network (DCDN) or Edge Security Acceleration (ESA) resources in the console.
Edge Security Acceleration (ESA)
Features | Feature | Description | References |
Website management | Version management | Version management lets you test, deploy, and roll back configuration changes based on custom request rules. | |
Analytics and logs |
| ||
DNS | DNS analytics gives you insight into your website's DNS traffic. It helps you monitor key metrics, analyze trends, and visualize data from multiple dimensions. Use these insights to track the real-time status of your DNS services and adjust your business strategy. | ||
SSL/TLS | This topic introduces the basic concepts of SSL/TLS protocols, their application in HTTPS encryption, and the role of related certificates. | ||
Security protection |
| ||
Speed and network |
| ||
Caching | After your site connects to , edge nodes determine whether to cache resource files based on your cache configuration rules. When an edge node caches a file, can serve subsequent requests for the same file directly from the edge. This reduces back-to-origin requests, delivers content faster, and lowers latency. If the requested content is not cached or has expired, retrieves the latest data from the origin server. | ||
Rules | ESA rules let you define conditions that control when specific feature configurations take effect. | ||
Traffic |
| ||
TCP/UDP proxy | TCP/UDP proxy forwards TCP and UDP traffic from edge ports to your origin server, improving application performance and security. Use TCP/UDP proxy for scenarios that rely on direct Layer 4 protocol connections, such as real-time competitive games and real-time audio and video interactions. | ||
Edge computing | Edge function | Functions and Pages is a full-stack edge development platform from Edge Security Acceleration (ESA). It integrates Git workflows, a global edge network, and an intelligent build system to deploy code from commit to global distribution. The platform supports static websites, SPAs, SSR applications, and edge functions. | |
Edge container | Edge Container is a serverless compute service that runs container applications on a global network of points of presence (POPs). By deploying your applications closer to your users, Edge Container significantly reduces latency and simplifies protocol handling. It automatically manages scaling and operations, so you can focus on developing your application instead of managing infrastructure. | ||
Edge storage | Edge KV is a globally distributed key-value store that runs at points of presence (POPs). Writes propagate to all POPs automatically, and Edge Routine (ER) reads data from the same POP where the request lands, keeping latency low. Common use cases include lightweight Blockchain as a Service (BaaS) and API gateway services. | ||
Analytics and logs | Account analytics | ESA analyzes access log data to provide account-level analytics and visualizations, including request and traffic distribution by country/region, encrypted requests, cache hit ratios, and error code counts. | |
Logs | Edge Security Acceleration (ESA) logs detailed information for every request. Log Service aggregates logs from various features for troubleshooting, generating monitoring metrics, and debugging site connectivity. | ||
Global settings | Groups | Global Settings lists are reusable collections of IP addresses, CIDR blocks, ASNs, or hostnames that you can reference across multiple WAF and bot management rules. When you update a list, the change propagates automatically to every associated policy. | |
Scenario-specific policies | Scenario policies automatically adjust DDoS protection for peak traffic events such as game launches or e-commerce promotions. Using the Major Events template, a policy dynamically adapts to traffic fluctuations within a preset period, reducing false positives for legitimate users and ensuring business continuity. | ||
Custom pages | When security rules block requests, ESA returns a default 403 intercept page or slider verification page branded with Edge Security Accelerator (ESA). Custom pages let you upload branded intercept pages or customize the slider verification page to match your brand. The custom pages feature consists of custom intercept pages and custom slider pages. | ||
Tools | IP geolocation | After you add your website to ESA, use IP geolocation to check whether client requests are routed to an ESA node IP address and verify that acceleration is effective. | |
Billing management | Plan management | Check your plan type, associated website, status, and expiration time in the ESA console. | |
Usage query | Query usage to view traffic overviews and detailed usage breakdowns for your websites or plans, helping you monitor and analyze traffic consumption. |
Dynamic Content Delivery Network (DCDN)
Features | Feature | Description | References |
Content delivery service | Domain name management | Set up DCDN in a few steps to enable integrated acceleration, edge computing, and security for your domains. | |
Business monitoring | Resource Monitoring tracks bandwidth, traffic, cache performance, and HTTP status codes for your accelerated domain names — broken down by the region or carrier of client IP addresses. Use it to identify traffic trends, diagnose origin errors, and optimize CDN configurations. Real-time monitoring gives you 1-minute granularity data on CDN traffic, bandwidth, and origin fetch status — with a data latency as low as 5 minutes. Use it to detect traffic spikes, track cache efficiency, and identify HTTP errors as they happen. | ||
Management tools | After you add an origin server to the DCDN service, use the IP Check feature to check whether an IP address is a DCDN point of presence (POP) and verify that acceleration is active. | ||
Edge security | DDoS mitigation | If an accelerated domain name experiences a DDoS attack, it may be added to a sandbox, which causes service interruptions. You can enable the DCDN DDoS mitigation feature for important domain names or those that are at risk of attacks. After you enable the feature, DCDN accelerates your services and provides real-time detection, a fast response, and automatic protection against DDoS attacks. | |
WAF protection | DCDN integrates Web Application Firewall (WAF) capabilities at DCDN points of presence (POPs) to identify malicious traffic and intercept malicious requests. | ||
Data center | Operations reports | Operations reports provide the offline analytics data of your accelerated domain names over different time periods. Use this data to understand how your accelerated domain names are running and to analyze the status of your business. | |
Log management | The log management service is used to analyze Dynamic Route for CDN (DCDN) logs to troubleshoot issues in a timely manner and improve service quality. This topic describes the log management service and features provided by DCDN. | ||
Edge computing service | Edge Routine | EdgeRoutine (ER) is a serverless computing service that runs JavaScript code on Alibaba Cloud's global points of presence (POPs). It supports ES6 syntax and standard Web Service Worker APIs. Requests execute on the POP nearest to each user, delivering ultra-low latency responses. | |
Edge storage | EdgeKV is a key-value edge storage service provided by points of presence (POPs). Data written to EdgeKV is automatically synchronized to POPs worldwide, allowing EdgeRoutine (ER) to read it locally. Together, EdgeKV and ER enable lightweight Blockchain as a Service (BaaS) and API gateway deployments. | ||
IP application acceleration | Layer 4 acceleration | IP Application Accelerator (IPA) is a Layer 4 acceleration feature of Alibaba Cloud DCDN. IPA accelerates TCP and UDP traffic to deliver low latency and high stability for real-time interactions such as social media messaging, online gaming, online education, and financial transactions. |
