Resource management in a cloud environment is a hard problem, due to: the scale of
modern data centers; the heterogeneity of resource types and their interdependencies; the …

The exponential growth of digital information is imposing increasing scale and efficiency
demands on modern storage infrastructures. As infrastructure complexity increases, so does …

Remote access to NVMe Flash enables flexible scaling and high utilization of Flash capacity
and IOPS within a datacenter. However, existing systems for remote Flash access either …

In data centers, the IO path to storage is long and complex. It comprises many layers or"
stages" with opaque interfaces between them. This makes it hard to enforce end-to-end …

PCIe-based Flash is commonly deployed to provide datacenter applications with high IO
rates. However, its capacity and bandwidth are often underutilized as it is difficult to design …

We conduct a comprehensive study of development and deployment issues of six popular
and important cloud systems (Hadoop MapReduce, HDFS, HBase, Cassandra, ZooKeeper …

In distributed systems shared by multiple tenants, effective resource management is an
important pre-requisite to providing quality of service guarantees. Many systems deployed …

With the increasing popularity of disaggregated storage and microservice architectures, high
fan-out and fan-in Remote Procedure Calls (RPCs) now generate most of the traffic in …

Meeting service level objectives (SLOs) for tail latency is an important and challenging open
problem in cloud computing infrastructures. The challenges are exacerbated by burstiness …

The cloud infrastructure motivates disaggregation of monolithic data stores into components
that are assembled together based on an application's workload. This study investigates …
