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

Amazon's introduction of the AWS i3 instance family offers significant advantages for I/O intensive applications, with features such as up to 15TB of fast storage and powerful Intel processors allowing up to 64 vCPUs per instance. ScyllaDB, known for its shard-per-core, lockless architecture, is well-suited to leverage the capabilities of i3 instances, achieving impressive performance metrics such as over one million operations per second in a single server. While ScyllaDB has yet to release official AMIs for i3 instances, customers have reported successful production deployments, although manual tuning is currently required due to kernel compatibility issues with the standard CentOS kernel. The i3 family is not only more powerful but also more cost-effective than its predecessor, the i2 family, promising significant reductions in operational costs. An upcoming ScyllaDB version is expected to offer full support for i3 instances, and a webinar is scheduled to guide users on optimizing the use of these new instances.
