Alibaba Cloud Global Accelerator Nanny-level Tutorial: Create a Standard Instance from 0 to 1
When operating overseas business, cross-border e-commerce, international SaaS or AI services, the biggest headache for developers is
User access speed is unstable
。
Inter-regional visits, in particular, often occur:
High delay: it takes several seconds to turn around when clicking on a web page.
Serious packet loss: game dropped and API calls frequently timed out.
Domestic access to international business instability: cross-sea fiber optic cable jitter led to business paralysis.
At this moment,
Alibaba Cloud Global Acceleration (GA) (Global Accelerator)
Is your good helper
GA: It provides a "global high-speed dedicated line" for your business, allowing users to access your source station through the internal backbone network of Aliyun.
1. Core Science: What is Global Acceleration GA?
You can think of GA:
"Intelligent Transfer Station" for Global Traffic"
。
When there is no GA: Users accessing your server is like taking ordinary provincial/county roads, which are long and easy to get stuck in traffic.
After GA is established, the user first accesses the "high-speed entrance" of Aliyun nearest to him, and the traffic enters the internal optical fiber network of Aliyun. The internal network has very low latency and no packet loss, directly reaching your origin server (Singapore, the United States, Hong Kong, etc.).
2. which sea scenes must use GA?
If you belong to the following businesses, GA is almost standard:
Cross-border e-commerce/SaaS: increasing the success rate of orders.
AI API service: Reduce the delay of the first package of large model calls.
Overseas games: reduce the Ping value of the battle, reduce the teleport and caton.
Foreign trade enterprise official website: to enhance the trust of overseas customers.
3. Preparation (Checklist)
Before you begin configuration, confirm that you are ready:
An origin server: whether in Alibaba Cloud (ECS), AWS, or an offline data center.
The public IP address of the server or the domain name of the Server Load Balancer (ALB/SLB).
Domain name: If it is a website business, it is recommended to prepare an SSL certificate in advance.
4. Practical Teaching: Creating Standard GA Examples
1. Enter the console
Log on to the Alibaba Cloud backend and search
"Global Acceleration GA"
Enter the management interface.
2. Select payment mode
Click "Create Standard Instance" and novice suggestions:
Pay-as-you-go (recommended): No need to prepay high monthly fees, pay as much as you want for traffic, which is very suitable for new project testing and traffic fluctuation business.
3. Configure basic instance information
Instance Name: We recommend that you name the instance by business, such as prod-web-ga.
Accelerated IP address type: Elastic IP address is selected by default ". This is the most common method. The system automatically allocates the optimal acceleration node IP to you.
4. Set the acceleration area
This is the core step:
Check your "user location".
For example: your server in the new
Canada, but the user is in Japan and Hong Kong, then the acceleration area is selected "Japan" and "Hong Kong".
Note: If accelerated for Mainland China users, domain names may need to be filed according to regulations.
5. Listener configuration (traffic entry)
The listener is like a security guard at the gate, deciding which protocols are allowed to enter:
Protocol selection: HTTPS is preferred for website business (more secure and in line with SEO trends).
Port: 443 for HTTPS and 80 for HTTP.
6. End node group (real server)
here refers to you
Back-end source station
:
Backend service protocol: It is recommended to be consistent with the listener.
Add backend: directly select "custom public network IP" and enter the real IP of your Singapore/US server.
5. Key Link: Health Check (Recommended)
The architect recommends:
Never turn off a health check.
Function: Automatically monitor your source station. If the source station goes down, GA will detect and stop the diversion in time to prevent users from seeing the error page.
Recommended configuration: protocol HTTP, path/, check frequency every 5 seconds.
6. Final Sprint: Resolving Domain Names and Testing
1. Get Accelerated IP
After submitting the configuration, wait 3-5 minutes. Found in the instance details
"Accelerated IP"
。
2. Modify DNS resolution
Go to your domain name registrar (e. g. Wanwang, GoDaddy) and point the original A record to this new
GA Accelerated IP
。
Error: Domain Name-> Origin Real IP (Slow)
Correct approach: domain name-> GA accelerated IP -> Alibaba Cloud backbone network-> origin station (fast)
7. Senior Architect Pit Avoidance Guide
The security group must be released: many people still find it impossible after configuration. the high probability is that the firewall (Security Group) of the source server has not released the IP segment of the GA back end or the corresponding 80/443 port.
Don't resolve the wrong IP: Please make sure that the domain name resolves the IP assigned by GA, not your source station IP, otherwise the acceleration is invalid.
HTTPS certificate matching: If HTTPS is configured on GA, make sure that the SSL certificate you upload exactly matches the domain name.
8. Summary: The True Value of GA
Aliyun Global Acceleration GA is not only "fast", its greatest value is
Stability
。
By shielding the complex environment of public network fluctuations, it is for you.
AI services, sea SaaS, international e-commerce
Provides enterprise-class network support. If your business is in the predicament of "losing customers due to poor network", GA is definitely the most cost-effective investment.
