How to orchestrate a distributed OpenStack [PDF]

open access: yesIEEE INFOCOM 2018 - IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2018
We see two important trends in ICT nowadays: the backend of online applications and services are moving to the cloud, and for delay-sensitive ones the cloud is being extended with fogs. The reason for these phenomena is most importantly economic, but there are other benefits too: fast service creation, flexible reconfigurability, and portability.

HBAC: Hierarchical‐Based Access Control Model for Storage Management in Data Lake Environments

open access: yesSoftware: Practice and Experience, Volume 56, Issue 4, Page 445-461, April 2026.
ABSTRACT Background Traditional storage systems typically use simple access control models that manage permissions at the user or group level. These models, however, are not well suited for data lake environments, where large‐scale and diverse datasets must be accessed concurrently by users across multiple hierarchical levels, and they also have many ...
