Faster and better: What to expect running Scylla on AWS i3 instances

AWS i3 monitoring

Amazon recently unveiled a new class of machines—the AWS i3 family. Targeted at I/O intensive applications and featuring up to 15TB of fast storage, these machines offer unprecedented power with a great balance between I/O and CPU. At a lower price than the previous i2 family, we expect the i3 family to become the default class for NoSQL workloads. This article will cover i3 instances and provide information about the status of Scylla support for the hardware. Although we don’t yet officially provide i3 AMIs, customers are already running them in production with positive results. Scylla’s native architecture takes advantage […]
