Abstract
Systems and methods are provided for providing a consistent experience for users of cloud-based block storage volumes. While cloud storage aims to remove hardware considerations for an end user's experience, block storage performance can nevertheless vary according to hardware configuration, such as the specific model of underlying hardware used to support a volume or the specific network location of that hardware. Embodiments of the present disclosure address that inconsistent performance by associating a volume with a performance profile, which can represent a desired distribution of performance for the volume. Each read or write can be compared to the profile, and may be selectively delayed to match the desired performance. This enables the cloud provider to vary physical hardware or network configurations without effect on block storage performance from the point of view of an end user.
