How to Protect Your Websites from DDoS Attacks

In this article, you will get some information on how to use Alibaba Cloud's Anti-DDoS Premium to protect critical assets and accelerate access for Mainland China users.

In this article, I'll show you how to use Alibaba Cloud's Anti-DDoS Premium to protect your critical assets against DDoS attacks. I'll also show you how to accelerate access for Mainland China users to your application hosted outside Mainland China, such as Singapore and China(Hong Kong), with the new Mainland China Acceleration (MCA) service.

Access the Anti-DDoS Premium console, purchase the Anti-DDoS Premium service together with the Mainland China Acceleration instance (you may contact Alibaba Cloud to assist you).

  1. For the Anti-DDoS Premium insurance plan: It provides 2 unlimited mitigations per month (unlimited plan available).
  2. For the Mainland China Acceleration plan: By default it provides 10Mb accelerated bandwidth between Mainland China and overseas.
    Now we can start configuring the Anti-DDoS + MCA services. Follow the steps to setup your domain to the console.

Next we will configure the MCA, so that for China Mainland users will use the MCA first, and fail-over to Anti-DDoS IP if MCA is under attack.

Switch to the Security Traffic Manager tab and click Add Rule. Add the MCA rule in which the MCA IP has a high priority and the Anti-DDoS IP is low Priority.

The Security Traffic Manager will generate a CNAME record, which is responsible for the traffic fail-over between the MCA IP and then Anti-DDoS Premium IP address if necessary.

Now we will configure the DNS service, so the user will be able to resolve demo.alibabacloudhk.com to MCA and Anti-DDoS Premium. Go to the Alibaba Cloud DNS service console. Under Domains, click on your domain name and Add Record.
