The purpose of this article is to share with you about how to repair the released CVM. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

If your CVM resource has been released by the service provider, you can use the data you previously backed up locally to restore it on the new server; if you don't have a backup, you can't recover it, you can only rebuild it.

Before creating a new CVM, in order to reduce possible cloud host outages, you should pay attention to the following.

Multi-faceted inspection of cloud vendors and data centers

The first step to avoid or reduce downtime is to evaluate the reliability of cloud service providers, and enterprises need to quantify the indicators. For example, the number of failures in a year, the cause of the failure, the time to recover after the failure, and so on. The most powerful guarantee for the reliability of a CVM is to determine the SLA at the time of negotiation. in addition, the power supply, failover or payment should be understood in detail.

Reduce network performance issu

The most common failure of cloud computing services is not itself, but the network, and the stability of the Internet is the source of most outages. To solve this problem, one is to ensure the security and compliance of the network, and the other is to adopt VPN. If the two can get the final contract confirmation, then at least there is a certain degree of performance guarantee. But you may have to pay an extra fee for it.

Solve the database problem of the CVM

After determining that there is nothing wrong with the data center and the network, the next thing to consider is the database. Cloud host lease will inevitably involve the database, if a failure occurs in the process of updating, then the integrity of the data may be lost. It is necessary to review the status of the database to ensure that there is no risk of loss or inconsistency in the stored data.

The CVM is secure and reliable, and there is 24-hour technical support from a professional after-sales team. Full-time staff will notify the renewal of the CVM before it expires. After the expiration of the CVM, users will keep the data for one month free of charge for you to retrieve it in time.

The above is how to repair when the CVM is released. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
