Auto-scaling containerized cloud applications: a workload-driven approach
No full textToday, cloud computing presents new business opportunities as it offers various technological advantages including elastic computing and efficient pricing strategies. Although, cloud users have access to large amount of resources, it is yet a challenging task to efficiently manage the hardware resources in a cloud environment. In this article, we present PACE (Performance- aware Auto-scaler for Cloud Elasticity), a framework for auto-scaling containerized cloud applications based on workload demand. The framework offers a) reactive auto-scaling using threshold-based rules to avoid application failures during intensive workload tasks and b) proactive auto-scaling using convolutional neural networks (CNN) and K-means to generate elastic scaling policies that incorporate future workload demands. The experimental analysis is based on the Yahoo! Cloud Serving Benchmark (YCSB) executed in Redis containers deployed on the Google Cloud Platform. The proposed framework can automatically adjust cloud resources to satisfy workload demand and ensure Quality of Service (QoS) requirements
Subverting the“migrant division of labor”through thetraditional retail market: the London Latin Village’s struggle against gentrification
Get PDFRetail gentrification describes the process by which the retail offer of a neighborhood is reconfigured to cater to a wealthier clientele than previously. This not only affects the ability of poorer urban residents to access essential goods and services but also has disruptive effect on existing communities. In this paper, we analyze the threat of gentrification and its impact on the experiences of migrant workers at the Latin Village, a Traditional Retail Market (TRM) in North London. We make two arguments based on a combination of qualitative research methods (interviews, participant observation, survey and document analysis). First, we find that the market offers a sense of belonging as well as economic opportunities to migrants, predominantly from Latin America, who face discrimination in many other parts of London’s stratified labour market. Second, we argue that regeneration of the Latin Village as originally envisaged would disproportionately affect this migrant community by threatening an important space of social and economic inclusion. The paper concludes by highlighting the importance of the workplace as a mediator of migrants’ experiences of the city, which calls for further attention to instances of workspace displacement engendered by processes of retail gentrification and their consequences for marginalized communities
Thermochronological constraints on Eocene deformation regime in the Long-Men Shan: implications for the eastward growth of the Tibetan Plateau
Get PDFUnderstanding the spatio-temporal distribution of strain during Cenozoic growth of the Tibetan Plateau is important for constraining the geodynamic processes underpinning plateau formation. Offset Quaternary land- forms and historic earthquake data suggest an along-strike change in deformation style for the eastern margin of the Tibetan Plateau, characterized by a transition from ESE-verging shortening to right-lateral shear from the southern to northern segment of the Long-Men Shan fault zone within a distance of ca. 500 km. When and how this along-strike deformation pattern formed is central to understanding the uplift history and spatio-temporal distribution of strain in the eastern margin of the Tibetan Plateau, and the underpinning geodynamics. To address this, we report a suite of low-temperature thermochronology data from the northern segment of Long- Men Shan fault zone that show a contrast in post late Cretaceous cooling and exhumation histories between the hinterland (west of the marginal Yingxiu-Beichuan fault) and foreland sides (east of the fault). Prior to the Eocene (ca. 40 Ma), the hinterland experienced significant exhumation in contrast to minor exhumation on the foreland side, but, post Eocene exhumation accelerated on the foreland side. This change reflects a switch in the deformation regime from shortening to strike-slip-dominated. This switch reduced hinterland rock uplift and tectonic and topographic loading over the foreland basin, leading to accelerated foreland exhumation through isostatic adjustments. A compilation of fault deformation history for the eastern Tibetan Plateau shows a second tectonic transition in the late Miocene, characterized by formation of the south-striking Huya and Minjiang faults. Our results highlight the importance of progressive late Eocene and late Miocene tectonic transitions in shaping the eastern margin of the Tibetan Plateau
Adorno's critique of work in Market Society
Get PDFJaakko Nevasto has offered a number of thoughtful criticisms of our
attempt to show that Adorno’s work can fruitfully be brought to bear on
topics in business ethics. After welcoming his constructive clarifications,
we attempt to defuse Nevasto’s main objections and defend our
application of Adorno, focusing in particular on the topics of moral
epistemology, needs, and the possibility of genuine activity – and thus
good work – within capitalist society
A bruise, a neck and a little finger: the visual archive of Ruth Ellis
Get PDFRuth Ellis was the last woman to be hanged in Britain. On April 10, 1955, in front of witnesses, she shot and killed her lover, David Blakely, and was immediately arrested and imprisoned. In so many other ways, however, her life was similar to those of many aspirational women of the working classes in postwar Britain; she achieved notoriety because of the murder and execution. This essay uses archives of press photography to examine the diverse ways in which Ellis constructed her identity and was represented to the public as a sexualized woman. It attempts a feminist encounter with the visual archive—an encounter not only with an individual woman but also, and as importantly, with 1950s sex, sexuality, class, and violence
Evolution of the continental margin of south to central Vietnam and its relationship to opening of the South China Sea (East Vietnam Sea)
Get PDFThe continental margin of south to central Vietnam is notable for its high elevation plateaus many of which are covered by late Cenozoic basalt flows. It forms the westernmost margin of a wide continental rift of the South China Sea (East Vietnam Sea), and uplift has been considered a result of either rifting or younger intraplate basalt magmatism. To investigate margin development apatite thermochronometry was applied to a dense array of samples collected from across and along the margin of south to central Vietnam. Results, including thermal history models, identified a distinct regional episode of fast cooling between c. 37 and 30 Ma after which cooling rates remained low. The fast cooling coincides with a period of fast extension across the South China Sea (East Sea) region that preceded continental break-up recorded by Oligocene grabens onshore. A thermal model is used test different processes that might influence the inferred cooling including a distinct pulse of exhumation; a decrease in exhumation followed by an associated transient decrease in geothermal gradients and, underplating coincident with rifting. Thermal relaxation following Mesozoic arc magmatism is ruled out as geotherms returned to background rates within 20 Myrs of emplacement, well before the onset of fast cooling. Models support fast cooling attributed to accelerated erosion during early stages of rifting. Some additional heating from either underplating, and/or hot mantle upwellings is also possible. No evidence was found to support regional uplift associated with the intraplate magmatism, enhanced monsoon-driven erosion or seafloor spreading dynamics
Implementing strategic changes in universities’ knowledge exchange profiles: the role and nature of managerial interventions
Get PDFIn a context of increasing managerialization of higher education and growing importance of the so-called ‘third mission’, universities increasingly seek to align their knowledge exchange (KE) profiles—i.e., the KE channels they use and the stakeholders with which they interact—to their institutional objectives. Using the lens of management control systems theory, we mapped changes in KE profiles to different management interventions. Building on 12 case studies of UK universities and combining content analysis and qualitative comparative analysis, we found that a) universities that had diversified their KE profiles had implemented belief and interactive control system interventions to encourage all staff members to exploit a wide range of KE opportunities; b) universities that had increased their KE specialization had implemented boundary and diagnostic control system interventions targeted at staff members performing specific KE activities; and c) universities that had reoriented their KE profiles had used a mix of interventions
