When creating a Tencent Cloud CVM, the instance type you specify determines the instance's host hardware configuration. Each instance type provides different computing, memory and storage features. You can choose the instance type that suits your application scale. Tencent Cloud provides a range of instance families with varying combinations of CPU, memory, storage, heterogeneous hardware, and network bandwidth. This gives you the flexibility in selecting the appropriate mix of resources for your applications.

Tencent Cloud CVM is pay-as-you-go. Instances can be activated and terminated at any time, and you only pay for resources used. This flexible billing mode lets you meet fluctuating demands while keeping costs low. In addition, usage is billed in seconds to further maximize your savings.

Glossary

Send/Receive Packets: the maximum number of data packets that the instance can process per second for both sending and receiving, without differentiating private or public network traffic.
Private Network Bandwidth Capacity: the maximum number of bits that the instance can transfer per second over private network
Multi-queue Technology: multiple send/receive packet queues are supported on a virtual ENI, with the sending and receiving of the data packets of each queue capable of being simultaneously processed by different CPUs
Number of Queues: the quantity of send/receive packet queues supported by each virtual ENI (N number of queues indicates that N number of receiving queues and N number of sending queues can be simultaneously supported)

Restrictions on Instances

The total number of instances that can be enabled in one region is limited. For more information, please see CVM Instance Purchase Limit.
Restrictions on system and data disks mounted on an instance: to ensure premium disk I/O performance, Tencent Cloud sets limits on the size and type of data disks purchased with an instance. For more information, see the supported disks of each instance family. You can also purchase separate cloud disks if you have higher disk requirements.
Note that the private network bandwidth capacity of an instance specification is the maximum private network bandwidth limit of the corresponding instance. If the CVM private network traffic exceeds this limit, random packet loss may happen within the private network for your instances.
The availability of instance specifications may vary from region to region. Some configurations may be sold out. Please see the purchase page for the latest information.
The send/receive packets performance data noted in this document is the results of a one-time network forwarding test. See Network Performance Test for the testing method. Separate testing is needed to estimate the performance for your business.

Here is a complete list of instance families.

Standard Instance Family

Standard instances provide a balance of compute, memory, and network resources to accommodate most applications.

Standard S6

As the latest generation of standard instances, S6 instances are powered by an all-new optimized virtualization platform, and provide balanced and stable compute, memory, and network resources. These instances are ideal for many applications.

Standard SA3

SA3 instances are optimized with the latest generation of AMD EPYC^TM processor. They deliver ultra-high cost performance with a variety of specifications, and provide a balance of compute, storage, and network resources, making them ideal for many applications.

SA3 instances come with the new AMD EPYC^TM Milan processors with the latest DDR4 memory. They are network optimized by default, offering a private network throughput up to 19 million pps and a private network bandwidth up to 100 Gbps.

Note:
this instance type is now only available to beta users. Contact your account manager to purchase it.

Features

Provides high performance with high reliability, security, and stability based on the Star Lake servers developed by Tencent Cloud
Comes with 2.55 GHz AMD EPYC^TM Milan processor, with a turbo frequency of 3.5GHz and the latest generation of 8-channel DDR4 for stable memory computing performance
Higher specification, SA3.58XLARGE940, offering 232 vCPUs and 940 GB memory
A wide range of CPU/RAM ratios, such as 1:2 and 1:4
Supports up to 100 Gbps of private network bandwidth for ultra-high packet throughput to meet extremely high private network transmission requirements
The network performance of an instance depends on its specification. A higher specification means a greater network forwarding performance and a higher private network bandwidth cap.

Use Cases

Standard SA3 instances are applicable to the following scenarios:

Enterprise applications of different types and sizes
Search and other computing clusters
Video encoding and decoding, video rendering and other applications sensitive to the single-core performance

Requirements

Supports pay-as-you-go.
Supports only VPC.
See below for available SA3 instance specifications. Make sure that the instance specification you choose meets the minimum CPU and memory requirements of your operating system and applications. In many cases, GUI operating systems (such as Windows) that consume extensive memory and CPU resources may need higher specifications. As the needs of your workload for memory and CPU increase, you can choose higher configurations or other instance types.
With the support of appropriate operating system kernel version and runtime environment, the instance’s network bandwidth can reach up to 100 Gbps. If the network throughput is larger than 10 million pps and the network bandwidth is higher than 50 Gbps, the kernel protocol stack consumes a lot of network resources. In this case, the resulted bandwidth of netperf test may not meet the expectation. To obtain the actual network performance of the instance, use the DPDK method to shield the difference caused by the kernel protocol stack.

The processor-to-memory ratio is 1: 8. The encrypted memory accounts for about 50% of the memory
Lowest price per GB of memory among instance types
The network performance of an instance depends on its specification. A higher specification means a greater network forwarding performance and a higher private network bandwidth cap.

Use Cases

These instances are ideal for:

Data sharing and computing, protecting confidential data shared between different users or vendors
Blockchain applications, enhancing the privacy and security of transactions and key storage, etc.

See below for available M6ce specifications:

Note:
If you use the key bound to hardware to encrypt data (such as SGX Sealing) in Intel SGX Enclave, you cannot decrypt the corresponding data once the host changes in the following scenarios. It is recommended that you back up data in the application layer to ensure the application reliability. Scenarios such as host failure, adjustment of instance types, no charges when shutdown, modification of instance placement group, etc., may lead to host changes.
