    Elastic Compute Service:Compute-optimized instance types

    Last Updated:Sep 18, 2024

    This topic describes the features of compute-optimized instance families of Elastic Compute Service (ECS) and lists the instance types of each instance family.

    c8a, compute-optimized instance family

    Features:

    • This instance family uses the innovative Cloud Infrastructure Processing Unit (CIPU) architecture developed by Alibaba Cloud to provide stable computing power, a more robust I/O engine, and chip-level security hardening.

    • Compute:

      • Offers a CPU-to-memory ratio of 1:2.

      • Uses 2.7 GHz AMD EPYCTM Genoa processors that deliver a turbo frequency of up to 3.7 GHz to provide consistent computing performance.

      • Allows you to enable or disable Hyper-Threading.

        Note

        By default, Hyper-Threading is enabled for ECS instances. For more information, see Specify and view CPU options.

    • Storage:

      • Is an instance family in which all instances are I/O optimized.

      • Supports only ESSDs and ESSD AutoPL disks.

        Note

        ESSDs and ESSD AutoPL disks are based on the Non-Volatile Memory Express (NVMe) protocol and support the multi-attach feature to meet the requirements of core enterprise business. For more information, see NVMe disks and Multi-attach for cloud disks.

      • Provides disk burstable IOPS and burstable bandwidth capabilities for low-specification instances.

      • Provides high storage I/O performance based on large computing capacity.

        Note

        For information about the storage I/O performance of the next-generation enterprise-level instance families, see Storage I/O performance.

    • Network:

      • Supports IPv4 and IPv6.

      • Supports elastic RDMA interfaces (ERIs).

        Note

        You can enable and accelerate inter-instance remote direct memory access (RDMA) based communications in virtual private clouds (VPCs). For information about how to use ERIs, see Configure eRDMA on an enterprise-level instance.

      • Supports the Jumbo Frames feature.

        Note

        Jumbo frames are Ethernet frames that have more than 1,500 bytes of payload, which is the limit specified by the IEEE 802.3 standard. Jumbo frames increase the payload size per packet and the percentage of the packet that is not packet overhead to provide high throughput and high network performance. For information about how to enable the Jumbo Frames feature, see the Jumbo frames section of the "MTUs" topic.

      • Provides ultra-high packet forwarding rates.

      • Provides network burstable bandwidth capabilities for low-specification instances.

      • Provides high network performance based on large computing capacity.

    • Security: Supports the virtual Trusted Platform Module (vTPM) feature and implements trusted boot based on Trusted Cryptography Module (TCM) or TPM chips to provide ultra-high security capabilities. During a trusted boot, all modules in the boot chain from the physical server to the ECS instance are measured and verified.

    • Supported scenarios:

      • Big data applications

      • Web applications

      • AI training and inference

      • Audio and video transcoding applications

    • Compatibility with operating systems

    c7t, security-enhanced compute-optimized instance family

    Features:

    • This instance family supports up to 128 GiB of encrypted memory and confidential computing based on Intel® Software Guard Extensions (SGX) to protect the confidentiality and integrity of essential code and data from malware attacks.

    • This instance family supports Virtual SGX (vSGX) and allows you to select instance types that meet your business requirements.

      Important

      If you use keys (such as SGX sealing keys) that are bound to hardware to encrypt the data of an instance within an Intel SGX enclave, the encrypted data cannot be decrypted after the host of the instance is changed. We recommend that you perform data redundancy and backup at the application layer to ensure application reliability.

    • This instance family implements trusted boot based on TCM or TPM chips. During a trusted boot, all modules in the boot chain from the underlying server to the guest operating system are measured and verified.

    • This instance family offloads a large number of virtualization features to dedicated hardware with the use of third-generation SHENLONG architecture to provide predictable and consistent ultra-high performance and reduce virtualization overheads.

      • Uses the third-generation Intel® Xeon® Scalable (Ice Lake) processors that deliver a base frequency of 2.7 GHz and an all-core turbo frequency of 3.5 GHz to provide consistent computing performance.

      • Allows you to enable or disable Hyper-Threading.

    • Storage:

      • Is an instance family in which all instances are I/O optimized.

      • Supports only ESSDs and ESSD AutoPL disks.

      • Provides high storage I/O performance based on large computing capacity.

    • Network:

    Note

    • Intel Ice Lake supports only remote attestation based on Intel Software Guard Extensions Data Center Attestation Primitives (Intel SGX DCAP) and does not support remote attestation based on Intel Enhanced Privacy ID (EPID). You must adapt applications before you can use the remote attestation feature. For more information about remote attestation, see Strengthen Enclave Trust with Attestation.

    • Intel SGX depends on host hardware. This instance family does not support hot migration.

    • Operations, such as changing instance types and enabling the economical mode, may cause the host of an instance to change. For instances of this instance family, the host change may cause data decryption to fail. Proceed with caution.

    • By default, failover is disabled. You can enable failover. For more information, see Modify instance maintenance attributes. Failover causes the host of an instance to change. For instances of this instance family, the host change may cause data decryption to fail. Proceed with caution.

    • When you create a security-enhanced instance, you must select a dedicated image to use the security features. For more information, see Create a trusted instance.

    • You can go to the Instance Types Available for Each Region page to view the instance types available in each region.

    • For more information about these specifications, see the "Instance type specifications" section in Overview of instance families. Packet forwarding rates vary significantly based on business scenarios. We recommend that you perform business stress tests on instances to choose appropriate instance types.

    Note

    • You can go to the Instance Types Available for Each Region page to view the instance types available in each region.

    • For more information about these specifications, see the "Instance type specifications" section in Overview of instance families. Packet forwarding rates vary significantly based on business scenarios. We recommend that you perform business stress tests on instances to choose appropriate instance types.

    • The results for network capabilities are the maximum values obtained from single-item tests. For example, when network bandwidth is tested, no stress tests are performed on the packet forwarding rate or other network metrics.
