Adaptive, Model-driven Autoscaling for Cloud Applications

Anshul Gandhi, Parijat Dube, Alexei A. Karve, Andrzej Kochut, Li Zhang
2014 IEEE International Conference on Autonomic Computing  
Applications with a dynamic workload demand need access to a flexible infrastructure to meet performance guarantees and minimize resource costs.  ...  Our implementation results on OpenStack using a multi-tier application under a range of workload traces demonstrate the robustness and superiority of DC2 over existing rule-based approaches.  ...  Queueing-network model Figure 2 shows a queueing-network model of a generic three-tier system with each tier representing a collection of homogeneous servers.  ...

The Unobservability Problem in Clouds

Anshul Gandhi, Parijat Dube, Alexei Karve, Andrzej Kochut, Harsha Ellanti
2015 2015 International Conference on Cloud and Autonomic Computing  
To address unobservability, we present and evaluate a practical solution to the unobservability problem that reveals important unobservable information without requiring any instrumentation or changes  ...  In this paper, we describe the unobservability problem and present various use cases from our experience managing a medium-scale cloud deployment with several hundred VMs and experiments on EC2 that highlight  ...  If a user requests a 1-core flavor VM, then depending on the availability, the VM might be launched on a hyperthreaded core that is being shared (two threads on a core) by other VMs.  ...

Towards efficient on-demand VM provisioning: Study of VM runtime I/O access patterns to shared image content

Andrzej Kochut, Alexei Karve, Bogdan Nicolae
2015 2015 IFIP/IEEE International Symposium on Integrated Network Management (IM)  
The results show a strong tendency for access pattern locality within common content clusters across VM images, regardless of the rest of the composition.  ...  Furthermore, it reveals a strong tendency for read accesses to refer to the same subsets of blocks within the common content clusters, while preserving the same ordering.  ...  A.  ...

VMAR: Optimizing I/O Performance and Resource Utilization in the Cloud [chapter]

Zhiming Shen, Zhe Zhang, Andrzej Kochut, Alexei Karve, Han Chen, Minkyong Kim, Hui Lei, Nicholas Fuller
2013 Lecture Notes in Computer Science  
A key enabler for standardized cloud services is the encapsulation of software and data into VM images.  ...  VMAR generates a block translation map at VM image creation / capture time, and uses it to redirect accesses for identical blocks to the same filesystem address before they reach the OS.  ...  If a block cannot find a corresponding entry in the map, it is a zero block. In this case, the VMAR driver simply uses memset to create a zero-filled memory buffer.  ...

Language (Technology) is Power: A Critical Survey of "Bias" in NLP [article]

Su Lin Blodgett and Solon Barocas and Hal Daumé III and Hanna Wallach
2020 arXiv   pre-print
Based on these findings, we describe the beginnings of a path forward by proposing three recommendations that should guide work analyzing "bias" in NLP systems.  ...  These recommendations rest on a greater recognition of the relationships between language and social hierarchies, encouraging researchers and practitioners to articulate their conceptualizations of "bias  ...  As a result, we excluded them from our counts for techniques as well.  ...

Towards scalable on-demand collective data access in IaaS clouds: An adaptive collaborative content exchange proposal

Bogdan Nicolae, Andrzej Kochut, Alexei Karve
2016 Journal of Parallel and Distributed Computing  
A critical feature of IaaS cloud computing is the ability to quickly disseminate the content of a shared dataset at large scale.  ...  We propose a different solution using a hybrid strategy that augments on-demand access with a collaborative scheme in which the VMs leverage similarities between their access pattern in order to anticipate  ...  (Figure 6(a) ).  ...
