常规用途虚拟机大小General purpose virtual machine sizes

常规用途 VM 大小提供均衡的 CPU 与内存之比。General purpose VM sizes provide balanced CPU-to-memory ratio. 适用于测试和开发、小到中型数据库和低到中等流量 Web 服务器。Ideal for testing and development, small to medium databases, and low to medium traffic web servers. 本文提供了有关常规用途计算的信息。This article provides information about the offerings for general purpose computing.

  • Av2 系列vm 可以部署在各种不同的硬件类型和处理器上。The Av2-series VMs can be deployed on a variety of hardware types and processors. A 系列 VM 的 CPU 性能和内存配置非常适合部署和测试等入门级工作负荷。A-series VMs have CPU performance and memory configurations best suited for entry level workloads like development and test. 根据硬件限制大小,为运行中的实例提供一致的处理器性能,不论硬件部署的位置。The size is throttled, based upon the hardware, to offer consistent processor performance for the running instance, regardless of the hardware it is deployed on. 若要判断此大小部署所在的物理硬件,请从虚拟机中查询虚拟硬件。To determine the physical hardware on which this size is deployed, query the virtual hardware from within the Virtual Machine. 示例用例包括开发和测试服务器、低流量 Web 服务器、中小型数据库、概念证明和代码存储库。Example use cases include development and test servers, low traffic web servers, small to medium databases, proof-of-concepts, and code repositories.

    A8 – A11 Vm 计划于3/2021 停用。The A8 – A11 VMs are planned for retirement on 3/2021. 有关详细信息,请参阅HPC 迁移指南For more information, see HPC Migration Guide.

  • B 系列可突增Vm 非常适合于不需要持续占用 CPU 完全性能的工作负荷,如 web 服务器、小型数据库以及开发和测试环境。B-series burstable VMs are ideal for workloads that do not need the full performance of the CPU continuously, like web servers, small databases and development and test environments. 这些工作负荷通常具有可突增的性能要求。These workloads typically have burstable performance requirements. B 系列使这些客户能够购买具有高性价比基线性能的 VM 大小,允许 VM 实例在 VM 使用的性能小于其基线性能时积累积分。The B-Series provides these customers the ability to purchase a VM size with a price conscious baseline performance that allows the VM instance to build up credits when the VM is utilizing less than its base performance. 如果 VM 已累积了积分,则 VM 可以在应用程序需要更高的 CPU 性能时突增到 VM 的基线之上,使用最多达到 100% 的 vCPU。When the VM has accumulated credit, the VM can burst above the VM’s baseline using up to 100% of the CPU when your application requires the higher CPU performance.

  • Dav4 和 Dasv4 系列在多线程配置中利用 AMD 的 2.35 Ghz EPYCTM 7452 处理器实现了新的大小,具有256多线程配置,每 8 mb 三级缓存专用于 8 mb 三级缓存,增加了运行其常规用途工作负载的客户选项。Dav4 and Dasv4-series are new sizes utilizing AMD’s 2.35Ghz EPYCTM 7452 processor in a multi-threaded configuration with up to 256 MB L3 cache dedicating 8 MB of that L3 cache to every 8 cores increasing customer options for running their general purpose workloads. Dav4 系列和 Dasv4 具有与 D & Dsv3 系列相同的内存和磁盘配置。The Dav4-series and Dasv4-series have the same memory and disk configurations as the D & Dsv3-series.

  • 在公有云中处理数据和代码时, DCv2 系列可帮助保护数据和代码的机密性和完整性。The DCv2-series can help protect the confidentiality and integrity of your data and code while it’s processed in the public cloud. 这些计算机由最新的具有 SGX 技术的最新的 Intel 2288G 处理器生成提供支持。These machines are backed by the latest generation of Intel XEON E-2288G Processor with SGX technology. 利用 Intel Turbo 提升技术,这些计算机可以高达 5.0 GHz。With the Intel Turbo Boost Technology these machines can go up to 5.0GHz. DCv2 系列实例使客户能够构建安全的基于 enclave 的应用程序,以在使用时保护其代码和数据。DCv2 series instances enable customers to build secure enclave-based applications to protect their code and data while it’s in use.

  • Dv2 和 Dsv2 系列Vm 是原始 D 系列的跟进,它具有更强大的 CPU 和最佳 CPU 到内存配置,使其适用于大多数生产工作负荷。Dv2 and Dsv2-series VMs, a follow-on to the original D-series, features a more powerful CPU and optimal CPU-to-memory configuration making them suitable for most production workloads. Dv2 系列比 D 系列快大约 35%。The Dv2-series is about 35% faster than the D-series. Dv2 系列在 Intel® Xeon® 8171M 2.1GHz (Skylake)、Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell) 或 Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) 处理器上运行,并采用 Intel Turbo Boost Technology 2.0。Dv2-series runs on the Intel® Xeon® 8171M 2.1GHz (Skylake), Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell), or the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors with the Intel Turbo Boost Technology 2.0. Dv2 系列的内存和磁盘配置与 D 系列相同。The Dv2-series has the same memory and disk configurations as the D-series.

  • Dv3 和 Dsv3 系列Vm 在超线程配置中运行在 Intel®强® 8171M 2.1 GHz (Skylake)、Intel®2673® E5-v4 2.3 GHz (Broadwell)或 Intel®至强® E5-2673 v3 2.4 GHz (Haswell)处理器上,为大多数常规用途工作负荷提供更好的价值主张。Dv3 and Dsv3-series VMs run on the Intel® Xeon® 8171M 2.1GHz (Skylake), Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell), or the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors in a hyper-threaded configuration, providing a better value proposition for most general purpose workloads. 在磁盘和网络限制已基于核心进行了调整以适应超线程技术的同时,内存已扩展(从 ~3.5 GiB/vCPU 到 4 GiB/vCPU)。Memory has been expanded (from ~3.5 GiB/vCPU to 4 GiB/vCPU) while disk and network limits have been adjusted on a per core basis to align with the move to hyperthreading. Dv3 系列不再具有 D/Dv2 系列的高内存 VM 大小,它们已被移动到内存优化Ev3 和 Esv3 系列The Dv3-series no longer has the high memory VM sizes of the D/Dv2-series, those have been moved to the memory optimized Ev3 and Esv3-series.
