[May 23, 2024] Tencent Cloud Upgrade Announcement for Traditional Account Type (Bill-By-CVM Accounts)

Last updated: 2024-09-10 18:25:18
Dear Tencent Cloud user,
Thank you for your long-term attention and support towards Tencent Cloud! Tencent Cloud accounts are classified into Standard Account Type (bill-by-IP accounts) and Traditional Account Type (bill-by-CVM accounts). To provide you with richer, higher-quality network services, Tencent Cloud plans to upgrade the existing Traditional Account Type to Standard Account Type in batches starting from May 23, 2024, and complete the upgrade of all Traditional Account Type by December 30, 2024. The Standard Account Type offers superior network bandwidth management and network features compared to the Traditional Account Type. For information on the distinction between account types, please refer to Checking Account Type. If you use a bill-by-CVM account, please pay attention to the upgrade notifications. If you wish to upgrade earlier, you may submit a ticket.
Upgrade Advantages:
Network bandwidth management and billing are both conducted on IP, allowing flexible migration to other CVM instances.
Using public network CLB services eliminates the need to purchase public network bandwidth for each background CVM; only bandwidth for the CLB needs to be purchased, making management more convenient.
The public network billing mode is more diverse, covering more business scenarios. For example, prepaid bandwidth package, daily settlement bandwidth package, main traffic bandwidth package, etc., supports coexistence with other billing modes in the same region such as hourly traffic, monthly bandwidth, hourly bandwidth, etc.
EIPv6 supports being added to the same BWP as IPv4 for joint billing.
Standard Account Type supports more product features and services, such as Premium EIP, High-defense EIP, CLB Cross-Region Binding 2.0, Domain-Based CLB, NAT Gateway support for binding Static Single-line IP, Standard NAT Gateway, and a wealth of monitoring indicators (such as CLB Ingress and Egress Bandwidth Utilization, Drop Metrics, etc.).
Upgrade Instructions:
The network will not be interrupted during the upgrade, and running business will not be affected.
During the upgrade, do not make configuration adjustments to resources through the console or API, such as changing billing modes or adjusting bandwidth, as these operations might not take effect.
The upgrade process takes about 5 minutes. If there are more than 500 CVM resources, the more there are, the longer the upgrade will take
After the upgrade, check and configure bandwidth monitoring and alarms on EIP and CLB.
If it involves purchasing CVM, EIP, and CLB via API calls, after the upgrade, network-related parameters need to be adjusted. For details, see The Impact on Console and API Calls.
When calling the RunInstances API to create a CVM that requires public network bandwidth, you need to set InternetMaxBandwidthOut to be greater than 0, and PublicIpAssigned to true to assign a public IP address. If InternetChargeType is BANDWIDTH_PACKAGE, you must specify the BWP ID for BandwidthPackageId.
When calling the AllocateAddresses API to create an EIP, you need to set the InternetChargeType and InternetMaxBandwidthOut parameters. If not set, the created EIP will be billed based on hourly traffic by default, with a bandwidth of 1 Mbps.
When calling the CreateLoadBalancer API to create a public network CLB, you need to set the InternetChargeType and InternetMaxBandwidthOut parameters. If not set, the created public network CLB will be billed based on hourly traffic by default, with a bandwidth of 10 Mbps.
During the upgrade, if the account has overdue payments or an abnormal CVM (e.g., shutdown due to overdue payment, resource isolation due to expiration, etc.), the upgrade cannot proceed. Please renew or terminate abnormal resources in time.

We appreciate your trust and support for Tencent Cloud. For more information, see Checking Account Type. If you have confirmed the impact of the upgrade, you can also submit a ticket for an early upgrade or seek online consultation.
Regards,
Tencent Cloud Team
