Families and Models

Last updated: 2024-01-08 09:12:28
    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.

    Instance Type

    Tencent Cloud instance families are categorized as follows:
    Type
    Sub-type
    Description
    Standard instances provide a balance of compute, memory, and network resources to accommodate most applications.
    Memory optimized instances feature large memory and are suitable for applications that require extensive memory operations, searches, and computations, such as high-performance databases and distributed memory caching.
    High I/O instances feature high random IOPS, high throughput and low latency. They are suitable for I/O-intensive applications that require high disk read/write performance and low latency, such as high-performance databases.
    This instance family is equipped with massive storage resources, features high throughput, and is suitable for throughput-intensive applications such as Hadoop distributed computing, massive log processing, distributed file systems, and large data warehouses.
    This family comes with a turbo frequency up to 3.8 GHz, and provides the highest single-core computing performance. It is suitable for compute-intensive applications such as batch processing, high performance computing, and dedicated game servers.
    -
    This family is equipped with heterogeneous hardware such as GPU and FPGA to deliver real-time, fast parallel computing and floating-point computing capabilities. It is suitable for high-performance applications such as deep learning, scientific computing, video encoding/decoding, and graphics workstations.
    Note:
    Some of the families are discontinued.

    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 SA3

    SA3 instances are optimized with the latest generation of AMD EPYCTM 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 EPYCTM 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 EPYCTM 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.
