How to improve network performance by modifying the bandwidth configuration of the instance when the existing network specifications of the instance do not meet the requirements

This article introduces how to improve network performance by modifying the bandwidth configuration of the instance when the existing network specifications of the instance do not meet the requirements, and focuses on the specific steps. The content of this article is compact, and I hope you can gain something from it.

ModifyInstanceNetworkSpec

Description

When calling this interface, you need to pay attention to:

Modify the package year When configuring the bandwidth of a monthly (PrePaid) instance:

The billing method can be upgraded or downgraded to PayByTraffic bandwidth.

The billing method can only be upgraded to bandwidth based on fixed bandwidth (PayByBandwidth).

When the public network outgoing bandwidth (InternetMaxBandwidthOut) is upgraded from 0 Mbps to a non-zero value, a public network IP will be automatically assigned.

You can use this interface to convert the bandwidth billing method from PayByTraffic to PayByBandwidth.

You can only convert the bandwidth billing method from fixed bandwidth (PayByBandwidth) to payby traffic (PayByTraffic) through the ECS management console.

When modifying the bandwidth configuration of a Pay-As-You-Go (PostPaid) instance:

You can upgrade or downgrade the bandwidth.

When the public network outgoing bandwidth (InternetMaxBandwidthOut) is upgraded from 0 Mbps to a non-zero value, the public network IP will not be automatically assigned. You need to call AllocatePublicIpAddress to allocate a public network IP to the instance.

Supports the conversion of bandwidth billing method based on traffic usage (PayByTraffic) to fixed bandwidth (PayByBandwidth).

Supports converting the bandwidth billing method from fixed bandwidth (PayByBandwidth) to usage traffic (PayByTraffic).

For Classic network type instances, when the public network outgoing bandwidth (InternetMaxBandwidthOut) is upgraded from 0 Mbps to a non-zero value, the instance must be in the Stopped state.

After upgrading the bandwidth, fees will be automatically deducted by default. You need to ensure that your account balance is sufficient, otherwise an abnormal order will be generated, and the order can only be canceled at this time. If your account balance is insufficient, you can set the parameter AutoPay to false. At this time, a normal unpaid order will be generated, and you can log in to the ECS management console to pay.

Each prepaid (annual and monthly) instance can reduce the public network bandwidth no more than three times, that is, the price difference refund will not exceed three times.

The refund of the price difference before and after modifying the bandwidth configuration will be refunded to your original payment method, and the used vouchers will not be refunded.

Every time a single instance is successfully operated, the operation cannot be continued within five minutes.
