Why does it still stop after recharging? Talk about Aliyun bill synchronization delay and manual re-machine skills.
"I have already recharged successfully. Why can't the server access all the deduction messages?"
"The console clearly shows that the available balance is positive, how is the instance status or' shutdown due to delinquent '?"
In Aliyun's daily operation and maintenance, this is one of the most maddening scenes. The company's business is being scolded because of the shutdown on the hot search. The technicians are anxious like ants on a hot pan, but the money is like a stone sinking into the sea, and the server will not come back to life.
Many people encounter this situation, the first reaction is that the Aliyun system is broken, or crazy to call customer service to reply. In fact, behind this involves the cloud vendor's
Underlying billing architecture design and deduction synchronization mechanism
.
Today, I don't talk nonsense in Mandarin. I will take you with the most down-to-earth real-life perspective.
thoroughly see through the underlying logic of alibaba cloud billing delay, and give you a few skills of "manual reprocessing" and "forced pull-up" that can save lives at critical moments.
.
Core Pain Point: Why Does Recharge Still Stop?
To understand this problem, we need to disassemble what the background system is doing when Aliyun faces an overdue account.
Many people think that the cloud server (ECS) is the same as your mobile phone bill, charging money into the system for second perception and second startup. But in reality, billing for cloud services is extremely complex, and it is divided
Subscription (prepaid) and pay-as-you-go (postpaid)
.
When your account is in arrears, you usually experience the following three fatal "time difference":
1. "Asynchronous communication" between the business system and the billing system"
Aliyun's "billing system" and the "ECS cluster control system" that controls the life and death of your servers are two independent architectures.
When you recharge: the money goes into the billing system's funds account and your available balance becomes positive.
Billing System Meeting: The billing system needs to settle your previous overdue bills and wipe out the accounts.
Notify the business system: the billing system notifies the ECS console: "This person has paid and can be released."
Real restart of ECS: ECS receives the command and starts to execute the startup logic.
This process will result in high concurrency or peak billing at the end of the month.
"Sync Delay" ranging from a few minutes to half an hour"
. This has led to the embarrassing situation of "the money has been charged, but the server has not received the power-on signal.
2. Pay-as-you-go "billing delay"
Pay-as-you-go (e. g. hourly bandwidth, cloud disk) is not a real-time deduction, usually every hour or every few days. If your account is out of service, after recharging, the system must give priority to running through the unpaid bills of the previous settlement cycle. The server will never turn on automatically until all overdue bills are completely written off.
Emergency combat: 3 skills forced manual recovery
If the business stops for one more minute, the company will be in thanks to one minute. Since we know that there is a delay in automatic synchronization, we cannot wait for the system to react. The following means of manual intervention can help you shorten the recovery time to a minimum.
Tip 1: Manually trigger "bill write-off" (most effective)
Most of the time the balance has changed, but because of the backstage queue, the bill has not yet been paid.
automatically removed. At this time, we need manual intervention to "push" it.
Log in to the Alibaba Cloud console and click Charges $\rightarrow $in the top navigation bar to go to Bill Management ".
In the menu on the left, click on "Outstanding Bills" or "Order Management".
If you see bills with the status of "unpaid" or "overdue to be paid" in the list, check them and click "manual payment" in the upper right corner ".
Select the "cash account balance" you just recharged to pay.
💡Core logic: As long as you manually delete the last overdue bill, the billing system will immediately send an unfreeze command to the ECS cluster, which is usually 5 to 10 minutes faster than the system's automatic polling.
Tip 2: Go to the ECS console to manually execute "startup"
When the bill is closed, some instances of certain types (or because you have set up a shutdown policy before) will not start up fully automatically, and it will stay in the "stopped" state.
Go to the ECS console.
Switch to the region where your server is located (such as Beijing and Hangzhou) and find the server with red or gray characters in the instance list.
Check its status. If the status has changed from "stopped due to arrears" to ordinary "stopped", the arrears limit has been lifted, but the system has not helped you press the power-on button!
Check the instance and click Start at the bottom ".
Skill 3: "Forced Renewal Pull-up" of Lightweight Application Server"
If you buy a "lightweight application server", the data will only be retained for a short period of time (usually 7-15 days) once the server is down due to arrears or expiration.
For such instances of prepaid expiration downtime, the top-up to account balance is
Totally useless
. You must go to the lightweight application server console, find the instance, and click directly on
"Renewal"
. Only when a clear renewal order is generated and the payment is successful, the system will perform distribution and boot.
Radical eradication: how to avoid being stuck with bills next time?
As a qualified operation and maintenance or stationmaster, it is extremely dangerous to pin the life and death of the business on "timely recharge. Establishing an automated financial line of defense is the way to go.
1. Turn on "Fully Automatic Delayed Shutdown" (life-saving setting)
Aliyun provides a name for enterprise authentication accounts or personal accounts with good credit
"Deferred No Shutdown"
The amount.
Find "Equity Management" or "Deferred No Downtime" in the expense center ".
After the application is opened, even if your account balance becomes negative, Aliyun will allow your service to continue to run normally for several hours to several days (depending on your credit limit), which gives you valuable recharge buffer time.
2. Configure Available Quota Alert"
Don't wait for the balance to become zero before charging.
Available Quota Alert is set in the expense center ".
For example, set a threshold: "When the available balance on that day is less than 100 yuan, immediately send an alarm to the main account mobile phone and DingTalk robot". In
Before the service is shut down, make up the funds.
3. Skillfully use "automatic renewal"
For fixed resources (such as ECS instance, cloud database RDS, domain name), check on the first day of purchase
"Automatic renewal"
. As long as you ensure that your cash account in Aliyun or the bound Alipay has living money, the system will automatically deduct the money to extend the validity period at the end of each month, completely eliminating the downtime tragedy caused by manual forgetting.
Cloud operation and maintenance, steady word head. Understand the delay logic of the bill, the next time you encounter the situation that you will not be able to recharge, go directly to the bill backstage and manually write off with one key, and calmly hold the dominant power in your own hands.
