Fog computing is a new paradigm that extends the Cloud platform model by providing
computing resources on the edges of a network. It can be described as a cloud-like platform …

Graph is a well known data structure to represent the associated relationships in a variety of
applications, eg, data science and machine learning. Despite a wealth of existing efforts on …

We present DevFS, a direct-access file system embedded completely within a storage
device. DevFS provides direct access without compromising file system integrity …

We design CrossFS, a cross-layered direct-access file system disaggregated across user-
level, firmware, and kernel layers for scaling I/O performance and improving concurrency …

Transaction logging and log shipping are standard techniques to provide recoverability and
high availability in data management systems. They entail an update to a local log file at …

Many cloud services perform periodic database backup to keep the data safe from failures
such as sudden system crashes. In the database system, two techniques are widely used for …

Fog computing has emerged as a new computing paradigm to overcome a number of
challenges faced by the cloud computing. It has extended the cloud computing standards to …

Log-structured-merge (LSM) trees are a highly write-optimized data structure for lightweight,
high-performance key-value (KV) stores. Furthermore, solid-state drives (SSDs) are a crucial …

In the history of access control, nearly every system designed has relied on the operating
system (OS) to enforce the access control protocols. However, if the OS (and specifically root …

As flash-based solid-state drive (SSD) becomes more prevalent because of the rapid fall in
price and the significant increase in capacity, customers expect better data services than …
