As the complexity and scale of cloud storage systems grow, software-defined storage (SDS) has become a prime candidate to simplify cloud storage management. In this work, the authors present IOStack: the first SDS architecture for object stores (such as OpenStack Swift). At the control plane, administrators provision SDS services to tenants according to policies expressed via a highlevel DSL. At the data plane, IOStack helps build a variety of filters, ranging from arbitrary computations on objects to data management mechanisms. Experiments illustrate that IOStack enables easy and effective policy-based provisioning, which can significantly improve the operation of a multitenant object store.
