Website management | Version management | The version management feature of Dynamic Content Delivery Network (DCDN) allows you to maintain different versions for custom website configurations and test, deploy, and roll back configuration changes. | |
Analytics and logs |
| ||
DNS | Alibaba Cloud Edge Security Acceleration (ESA) provides a powerful and flexible Domain Name System (DNS) service. You can select NS or CNAME to set up your domain when you add your website to ESA. After you add your website to ESA, ESA provides features such as static and dynamic content delivery, security protection, and edge computing for the website. This improves the user experience and security of your website. | ||
SSL/TLS | Hypertext Transfer Protocol Secure (HTTPS) is an extension of Hypertext Transfer Protocol (HTTP) and can encrypt data by using the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocol. You can use HTTPS to prevent data from being eavesdropped on, intercepted, or tampered with by third parties. Dynamic Content Delivery Network (DCDN) allows you to configure SSL/TLS certificates to verify the security of connections between clients and servers. | ||

Speed and network |
| ||
Caching | After you add a website to Edge Security Acceleration (ESA), ESA points of presence (POPs) determine whether to cache resources that are requested by clients based on configured cache rules. After a POP caches a file, when clients request the file, the POP responds the file to clients without retrieving the file from the origin server over a long route. This reduces latency and improves load times. If the requested file does not exist on the POP or has expired, the POP asks the origin server for the most recent file. | ||
Rules | You can configure rules to specify whether the configurations of Edge Security Acceleration (ESA) take effect for specific requests based on the characteristics of the requests. This helps meet your business requirements such as applying specific settings to requests with different characteristics, redirecting requests, and configuring specific origin servers. | ||
Traffic |
| ||
TCP/UDP proxy | If your application establishes connections with the origin server over the Transmission Control Protocol (TCP) or User Datagram Protocol (UDP), you can enable the TCP/UDP acceleration feature to improve application performance and security. The most common TCP or UDP-based scenarios include real-time combat gaming and real-time interactive audio and video streaming. | ||
Edge computing | Edge Routine | Edge Routine is a serverless runtime environment that allows you to write JavaScript code and deploy and execute it on Alibaba Cloud points of presence (POPs) worldwide. Edge Routine supports ES6 syntax and standard Web Service Worker APIs. With Edge Routine, user requests can be responded to and processed by the POP that is closest to users. This significantly reduces latency, accelerates response, and enhances user experience. | |
Edge Container | Edge Container provides elastic, easy-to-maintain computing resources based on containerized applications. Edge Container implements global deployment and proximity-based scheduling on points of presence (POPs) all over the world. This simplifies protocol processing and reduces response latency. You do not need to purchase server resources or worry about application scaling and O&M. This allows you to focus on application development rather than underlying infrastructure management. | ||
Edge KV | Points of presence (POPs) provide the edge storage service Edge KV, which is based on key-value pairs. After you write data to Edge KV, the data can be automatically synchronized to POPs around the world. Edge Routine can read and use the key-value pairs on the same POP. You can use Edge KV together with Edge Routine to deploy lightweight Blockchain as a Service (BaaS) services and API gateway services. | ||
Analytics and logs | Account analytics | ESA visualizes access statistics to provide multi-dimensional traffic analytics for your websites, such as the number of requests and traffic volume by country and region, encrypted requests, cached traffic rate, and number of error codes. | |
Real-time logs | Edge Security Acceleration (ESA) logs requests to your website. It collects and aggregates the logs generated by each module for you to view. You can use these logs to troubleshoot faults, generate monitoring metrics, and debug or test network connectivity between clients and your website. | ||
Global settings | Lists | If you want to perform JavaScript validation and bot management for multiple IP addresses or CIDR blocks, you can specify different IP addresses or CIDR blocks in a list. Then, you can reference the list when you configure protection rules such as Web Application Firewall (WAF) or bot management rules. This helps prevent repeated entry of IP addresses or CIDR blocks. | |
Scenario-specific policies | Your website anticipates much higher traffic than usual during major events such as new game launching and e-commerce promotions. In this case, you can create scenario policies to apply the Major Events template. This template automatically adjusts anti-DDoS protection policies during major events to prevent blocking normal requests. | ||
Custom error pages | By default, pages with an Edge Security Acceleration (ESA) identifier and the 403 error code are returned for requests that are blocked by ESA. If you want to use a personalized page with a business identifier, you can create a custom error page. | ||
Tools | IP geolocation | After you connect a website to Alibaba Cloud Edge Security Acceleration (ESA), you can use the IP geolocation feature to check whether the actual IP address that clients request to access belongs to an ESA point of presence (POP) and determine whether acceleration takes effect. | |
Billing | Plan management | You can query information about your plans, such as the plan type, status, expiration time, and associated websites, to better manage the plans. | |
Usage query | When using Edge Security Acceleration (ESA) for your websites, you can query the traffic usage for each individual website or for all websites covered by a specific plan. This data can help you analyze traffic patterns and make informed decisions accordingly. |
