AWS Tackles IO Performance in the Cloud

James Hamilton from AWS writes of a new innovation that delivers real-world IO performance in the Cloud.

Yesterday an ideal EC2 instance type was announced. It’s the screamer needed by these workloads. The new EC2 High I/O Instance type is a born database machine. Whether you are running Relational or NoSQL, if the workload is I/O intense and difficult to cost effectively scale-out without bound, this instance type is the solution. It will deliver a booming 120,000 4k reads per second and between 10,000 and 85,000 4k random writes per second. The new instance type:

  • 60.5 GB of memory
  • 35 EC2 Compute Units (8 virtual cores with 4.4 EC2 Compute Units each)
  • 2 SSD-based volumes each with 1024 GB of instance storage
  • 64-bit platform
  • I/O Performance: 10 Gigabit Ethernet
  • API name: hi1.4xlarge
