      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 Instance Family Standard instances provide a balance of compute, memory, and network resources to accommodate most applications.
      Memory Optimized Instance Family 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 Instance Family 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.
      Big Data Instance Family Big Data D2 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.
      Computing Instance Family This family comes with a powerful processor with a base frequency of 3.2GHz, and provides the highest single-core computing performance. It is suitable for compute-intensive workloads such as batch processing, high performance computing, and dedicated game servers.
      Heterogeneous Computing Instance Family - 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 Instance Family

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

      Standard S5

      Standard S5 instances are the latest generation of standard instances. Based on an all-new optimized virtualization platform, this family provides a balance of stable computing, memory, and network resources. This is a premium choice for many applications.

      • New Intel Advanced Vector Extension (AVX-512) instruction set

      • 1:2 or 1:4 processor to memory ratio.

      • Supports up to 28 Gbps of private network bandwidth for ultra-high packet throughput to meet the needs of extremely high private network transmission demand

      • The network performance of an instance is determined by its specification. A higher specification means a greater network forwarding performance and a higher maximum private network bandwidth limit.

      Application Scenarios

      Standard S5 instances are applicable to the following scenarios:

      • Enterprise applications of different types and sizes

      • Small and medium-sized database systems, caches, and search clusters

      • Computing clusters, memory-intensive data processing

      • Scenarios that require sending and receiving massive network packets, such as video on-screen comments, live video broadcasting, and gaming

      Requirements

      • S5 instances are pay-as-you-go.

      • S5 instances can only be launched in a VPC.

      • Configuration purchase is available for S5 instances. Please see the instance specifications below. Make sure that the size of the S5 instance you choose meet the minimum CPU 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 larger instances. As the needs of your workload for memory and CPU increase, you can expand to higher configurations or choose other instance types.
