Families and Models

Last updated: 2024-05-08 09:49:44
    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.

    Compute clusters, memory-dependent data processing.
    Scenarios with high demanding of network packet receive and send processing, such as video danmaku, live streaming, games, etc.

    Instance Requirements

    S8 instances can be used as monthly subscription instances as well as pay-as-you-go billing instances.
    S8 instances can only be launched in a Virtual Private Cloud.
    It is recommended to pair with the TencentOS Server operating system for optimal application performance of the instance.
    See the specifications below to see the sizes of S8 instances available for purchase. Ensure the size of the S8 instance you choose meets the minimum CPU and memory requirements of your operating system and application.
    An Instance can support up to 120 Gbps of network bandwidth, depending on the kernel version and runtime environment of the instance operating system. When PPS exceeds 10 million and the bandwidth exceeds 50 Gbps, the kernel protocol stack can cause significant network performance loss. In such cases, the bandwidth values tested by netperf may not meet expectations. The DPDK method can be used to overcome the differences in the cloud server's kernel protocol stack, getting the instance's real network performance. For testing methods, see high-throughput network performance testing.

    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.

    The network performance of instances corresponds to their specifications. Higher specifications result in stronger network forwarding performance and higher private network bandwidth limits.
    Supports the configuration to disable or enable Hyper-Threading.
    Supports burst bandwidth.
    Note:
    Burst bandwidth: The size of private network bandwidth is related to instance specifications, each having its own maximum private network bandwidth limit. In scenarios where network traffic surges within a short duration, Tencent Cloud servers offer burst bandwidth processing capabilities. For cloud servers that meet burst conditions, exceeding of the private network bandwidth limit for a short period is allowed, catering to customer business needs.
    Supports Jumbo Frames
    Note:
    Jumbo frames: Tencent Cloud supports sending Ethernet frames with an 8500-byte payload. Using Jumbo frames can fully maximize network performance, making it suitable for storage scenarios and other high traffic situations, thereby enhancing transmission efficiency.

    Use Cases

    The MEM-optimized M8 instance is highly suitable for the following scenarios:
    High-performance databases, distributed memory caching, and other applications that require extensive memory operations, searches, and computations.
    Users who build their own Hadoop clusters or use Redis for gene computing purposes.
    Scenarios with high demanding of network packet receive and send processing, such as video danmaku, live streaming, games, etc.

    Instance Requirements

    M8 instances can be used as monthly subscription instances as well as pay-as-you-go billing instances.
    M8 instances can only be launched in a Virtual Private Cloud.
    It is recommended to pair with the TencentOS Server operating system for optimal application performance of the instance.
    Refer to the specifications below to see the sizes of M8 instances available for purchase. Ensure the size of the M8 instance you choose meets the minimum CPU and memory requirements of your operating system and application. In many use cases, operating systems with GUIs that consume a lot of memory and CPU resources (such as Windows) may need larger instance sizes. As your workload's memory and CPU needs increase over time, you can scale to higher configurations or choose other types of instances.
    Depends on the support from the instance's operating system kernel version and runtime environment. When PPS exceeds 10 million and the bandwidth exceeds 50 Gbps, the kernel protocol stack can cause significant network performance loss. In such cases, the bandwidth values tested by netperf may not meet expectations. The DPDK method can be used to overcome the differences in the cloud server's kernel protocol stack, getting the instance's real network performance. For testing methods, see high-throughput network performance testing.
