Serverless Performance Modeling with CPU Time Accounting and the Serverless Application Analytics Framework

Thesis (Master's)--University of Washington, 2021Recently serverless computing platforms have emerged to provide appealing options to developers for deploying cloud native applications. One of the most popular serverless computing delivery paradigms known as Function-as-a-Service (FaaS) offers many desirable features including high availability, fault tolerance, and automatic application scaling. Understanding performance of FaaS workloads in the cloud involves new challenges as FaaS workloads are billed to the nearest millisecond, infrastructure is temporary, and observability of hardware configuration, load balancing, and function tenancy is notoriously obscure. To better understand FaaS workload performance to enable accurate performance predictions, we propose a novel performance modeling approach that leverages Linux CPU Time Accounting (CPU-TA). We introduce the Serverless Application Analytics Framework (SAAF), our tool used to collect information about the infrastructure running FaaS platforms, and use this to train models to predict FaaS workload runtime. Using 10 different serverless applications, we compare our CPU-TA modeling approach to baseline performance modeling approaches that directly predict runtime. Enabling accurate performance predictions on FaaS platforms allows developers and researches to make informed deployment decisions resulting in faster performance and reduced hosting cost. We found our runtime prediction technique was able to make accurate performance predictions across 448 different FaaS configuration scenarios, achieving average prediction accuracy of over 95%

The emerging geographies of work and identity: Exploring alternative employment strategies and work subjectivities of women with multiple sclerosis (MS).

Multiple sclerosis (MS) is a progressive disorder of the central nervous system producing a varied range of symptoms affecting physical, cognitive, and sensory functioning. The variability and unpredictability of impairments, their duration and intensity on a day to day basis, and ongoing health impacts present formidable challenges to securing and maintaining employment. Research suggests, despite having recent and extensive work histories, as many as 70-80 percent of individuals with MS are unemployed after diagnosis. For women with MS, the challenge of negotiating paid and non-paid work responsibilities often leads to difficult choices about how to navigate these changing lifeworlds. For this reason, some women have explored non-standard work approaches such as self-employment, home-based work, and telework as alternatives to standard wage and salaried employment. This case study examines how women with MS navigate barriers to employment, strategies used to create alternative work options, and the ways in which intersecting social identities are renegotiated in the process. These work experiences are situated in the context of a changing new economy, state and economic restructuring processes, and the increasing privatization of public sector services. Understanding how the lives of women with MS are affected in alternative work contexts enables us to better identify how and if emerging employment strategies are empowering to women and whether they should be supported more vigorously at a policy level. Findings indicate alternative employment approaches offer increased flexibility, an opportunity for greater work-life balance, and the possibility for generating additional income that can be packaged with other income sources. However, these work strategies often place undue responsibility for success or failure on the woman with MS without accounting for complex social, economic, programmatic, and policy factors that equally impact the viability and sustainability of these options

Cost and Returns from Reseeding Plains Ranges in Wyoming

Variable costs of reseeding 64 range sites totaling over 10,000 acres of plains type range in Wyoming averaged $14.26 per acre, and total costs averaged$16.31 per acre at 1972 cost levels. Information obtained from the ranch operators, together with experimental information from various sources and budgeting methods over time, were used to estimate a flow of returns. Investment costs of the reseeding occur immediately, as do costs for deferment. In the third year after reseeding, some beneficial effects are achieved. Full benefits of reseeding, including a higher percentage calf crop and a larger number of heavier yearlings available for sale, are not achieved until the fifth year. Allowing for the lag in response, the rate of return on reseeding Wyoming plains ranges is estimated at approximately 21.5% at 1972 cost and price levels.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
