即日起,Amazon Elastic Compute Cloud (Amazon EC2) C8i 实例已在欧洲地区(爱尔兰)和亚太地区(新西兰)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,C8i 实例的性价比可提升高达 15%,内存带宽可增加 2.5 倍。其性能较 C7i 和实例提升了高达 20%,特定工作负载的性能提升甚至更为显著。与 C7i 相比,C8i 实例在 NGINX Web 应用程序中的速度提升高达 60%,在人工智能深度学习推荐模型中的速度提升高达 40%,在 Memcached 存储中的速度提升 35%。

C8i 实例是所有内存密集型工作负载的绝佳选择,尤其适合需要最大实例大小或持续高 CPU 使用率的工作负载。C8i 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。

要开始使用,请登录 AWS 管理控制台。客户可以通过节省计划、按需型实例和竞价型实例购买这些实例。有关新的 C8i 实例的更多信息,请访问 AWS 新闻博客
