即日起,Amazon Elastic Compute Cloud(Amazon EC2)R8i 和 R8i-flex 实例已在 AWS GovCloud(美国东部)区域推出。这些实例由定制英特尔至强 6 处理器提供支持,仅在 AWS 上可用,在云中的同类英特尔处理器中性能最高,内存带宽最快。与上一代基于英特尔的实例相比,R8i 和 R8i-flex 实例的性价比提升高达 15%,内存带宽增加了 2.5 倍。它们的性能比 R7i 实例高 20%,特定工作负载的性能甚至提升更多。与 R7i 相比,PostgreSQL 数据库的速度提升高达 30%,NGINX Web 应用程序的速度提升高达 60%,AI 深度学习推荐模型的速度提升高达 40%。

R8i-flex 是我们的首款内存优化型 Flex 实例,是大多数内存密集型工作负载获得性价比优势的最简单方法。R8i-flex 实例提供最常见的大小,从 large 到 16xlarge。对于没有充分利用所有计算资源的应用程序来说,这是不错的首选。

R8i 实例是所有内存密集型工作负载的绝佳选择,特别是对于需要最大实例大小或持续高 CPU 使用率的工作负载。R8i 实例提供 13 种大小,包括 2 种裸机大小以及适用于超大型应用程序的全新 96xlarge 大小。R8i 实例已获得 SAP 认证,可以提供高达 142,100 aSAPS 的性能,为任务关键型 SAP 工作负载带来卓越性能表现。

要开始使用,请登录 AWS 管理控制台。有关 R8i 和 R8i-flex 实例的更多信息,请参阅 AWS 新闻博客
