Amazon EC2 X2gd instances are the next generation memory-optimized instances and are designed for running large-scale and in-memory applications.
Memory optimized Note R8g and X8g instance types support configurable bandwidth weightings. With these instance types, you can optimize an instance's bandwidth for either networking performance or Amazon EBS performance. The following table shows the default Amazon EBS bandwidth performance for these ...
For example, a larger or a memory-optimized instance type. Reboot the instance to return it to a non-impaired status. The problem will probably occur again unless you change the instance type. Instance store-backed Do one of the following: Terminate the instance and launch a new instance...
改变单个 EC2 instance 的规格(垂直扩容)! 方法也是滚动替换,最后替换主库,主库会主动下线,通过 log 传递给从库,快速进行选主(或者切主),可以减小 downtime 时间 修改分片数 增加分片用来扩展读写性能,增加内存的容量(扩大数据库规模)。 数据迁移和 拓扑变更两个阶段,数据迁移和 redis一样,源端获取迁移 slot ...
越来越多的公司发现通过购买硬件来满足周期性的负载需求会浪费大量开销,因为在一年当中的大多数时间,这些设备都处于闲置状态。而应对这种负载高峰并且最小化开销的方式之一就是使用云服务,比如Amazon EC2 instance。 本教程将会为虚拟化管理员展示如何使用vCloud Automation Center(vCAC)5.2 来对Amazon Elastic Compute Clo...
