IOStack: Software-Defined Object Storage

Raul Gracia-Tinedo, Pedro Garcia-Lopez, Marc Sanchez-Artigas, Josep Sampe, Yosef Moatti, Eran Rom, Dalit Naor, Ramon Nou, Toni Cortes, William Oppermann, Pietro Michiardi
2016 IEEE Internet Computing  
In response to these challenges, Software-Defined Storage (SDS) has recently become a prime candidate to simplify storage management in the cloud.  ...  Policies may target storage automation and/or specific SLA objectives. At the data plane, policies define the enforcement of SDS services, namely filters, on a tenant's requests.  ...  CONCLUSIONS AND FUTURE WORK We presented IOStack: the first Software-Defined Storage architecture for object storage (OpenStack Swift).  ...

TOSDS: Tenant-centric Object-based Software Defined Storage for Multitenant SaaS Applications

Aditi Sharma, Parmeet Kaur
2021 Arabian Journal for Science and Engineering  
The paper proposes a tenant-centric approach to develop an object-based software defined storage system for SaaS multi-tenant applications.  ...  We present TOSDS (Tenant-centric Object-based Software Defined Storage), a system that can efficiently meet the storage requirements of users or tenants with diverse needs who are using a multitenant SaaS  ...  IOStack [29] is another software-defined storage system for a multitenant object store unlike IOFlow which supported file system storage.  ...
