Avec les récentes réformes, dont la loi Hôpital, Patient, Santé et Territoires (HPST) de Juin 2009, l’hôpital s’est transformé non seulement dans sa forme organisationnelle par la mise en oeuvre des pôles mais aussi dans son rapport à son environnement. Cette organisation polaire vise à rechercher une performance par une approche médico-économique. Ainsi les dispositifs de gestion ont été mis en place et cherchent à rendre compte de cette performance. Dans ce contexte, comment peuvent travailler des professionnels de champs aussi différents que celui de la gestion et celui du soin ? La gestion sous-entend une optimisation des moyens, alors que le service public défend en priorité des valeurs d’utilité sociale et d’attention aux usagers. Les acteurs du soin ont une forte identification professionnelle à cette mission d’utilité sociale. Dans ce travail, nous proposons d’identifier en quoi les décalages culturels au sein des pôles hospitaliers, participent à une perte de sens et de reconnaissance des agents à leur travail. Ces écarts culturels seront appréciés plus précisément au travers de l’appropriation des outils de gestion. Cette étude se base sur des entretiens réalisés au sein de différents hôpitaux (CHU et CH) et de secteur Médecine, Chirurgie, Obstétrique (MCO) et psychiatrie. Elle révèle lanécessité de pratiques managériales innovantes tournées notamment vers la gestion interculturelle afin que chaque acteur de ces nouvelles structures hospitalières se sente compris et intégré dans cette dynamique. L’étude proposée peut constituer un retour d’expérience intéressant pour mieux comprendre et améliorer l’utilisation des nouveaux outils de gestion. Des préconisations sont proposées et peuvent constituer des pistes de réflexion afin de répondre aux défis actuels de l’hôpital public. / With the latest reforms, among which the Hospital, Patient, Healthcare and Territory (HPST) Law, the French Hospital has changed not only the form of its organisation through the implementation of a polar organisation, but also its environmental concern. This polar organisation aims to strive for performance and efficiency via an managerial and medical approach. Thus, some management tools have been set up aimed in particular at giving feedback on such performance. In this context, how can professionals from such distinct fields as management and healthcare work? Management implies the optimization of resources when the public sector above all upholds values of social usefulness and patient care. Healthcare actors feel very much involved in this mission of social usefulness. In this work we propose to identify how cultural gaps within hospital poles contribute to a loss of meaning and acknowledgment among healthcare agents. Those cultural gaps will be examined more particularly through management tool appropriation. This study relies on interviews conducted in various healthcare facilities (PCO and psychiatric hospitals of various capacities such as CHU and CH). It reveals the need for innovative managerial practices, especially designed for intercultural management, so that every actor of these new hospital facilities may feel that they are understood and integrated in this dynamic process. The proposed study can make up interesting feedback to better understand and improve the use of these new management tools. Recommendations are issued that can be food for thought to meet the current challenges of public hospitals.

I dagens informationssamhälle pågår en växande trend av molnbaserade tjänster. Vid implementering av molnbaserade tjänster används metoden Virtualisering. Denna metod minskar behovet av antal fysiska datorsystem i ett datacenter. Vilket har en positiv miljöpåverkan eftersom energikonsumtionen minskar när hårdvaruresurser kan utnyttjas till sin fulla kapacitet. Molnbaserade tjänster skapar samhällsnytta då nya aktörer utan teknisk bakgrundskunskap snabbt kan komma igång med verksamhetsberoende tjänster. För tillämpning av Virtualisering används en så kallad Hypervisor vars uppgift är att distribuera molnbaserade tjänster. Efter utvärdering av vetenskapliga studier har vi funnit att det finns skillnader i prestanda och funktionalitet mellan olika Hypervisors. Därför väljer vi att göra en prestanda- samt funktionsanalys av Hypervisors som kommer från de största aktörerna på marknaden. Dessa är Microsoft Hyper-V Core Server 2012, Vmware ESXi 5.1.0 och Citrix XenServer 6.1.0 Free edition. Vår uppdragsgivare är försvarsmakten som bekräftade en stor efterfrågan av vår undersökning. Rapporten innefattar en teoretisk grund som beskriver tekniker bakom virtualisering och applicerbara användningsområden. Genomförandet består av två huvudsakliga metoder, en kvalitativ- respektive kvantitativ del. Grunden till den kvantitativa delen utgörs av ett standardsystem som fastställdes utifrån varje Hypervisors begränsningar. På detta standardsystem utfördes prestandatester i form av dataöverföringar med en serie automatiserade testverktyg. Syftet med testverktygen var att simulera datalaster som avsiktligt påverkade CPU och I/O för att avgöra vilka prestandaskillnader som förekommer mellan Hypervisors. Den kvalitativa undersökningen omfattade en utredning av funktionaliteter och begränsningar som varje Hypervisor tillämpar. Med tillämpning av empirisk analys av de kvantitativa mätresultaten kunde vi fastställa orsaken bakom varje Hypervisors prestanda. Resultaten visade att det fanns en korrelation mellan hur väl en Hypervisor presterat och vilken typ av dataöverföring som den utsätts för. Den Hypervisor som uppvisade goda prestandaresultat i samtliga dataöverföringar är ESXi. Resultaten av den kvalitativa undersökningen visade att den Hypervisor som offererade mest funktionalitet och minst begränsningar är Hyper-V. Slutsatsen blev att ett mindre datacenter som inte planerar en expansion bör lämpligtvis välja ESXi. Ett större datacenter som både har behov av funktioner som gynnar molnbaserade tjänster och mer hårdvaruresurser bör välja Hyper-V vid implementation av molntjänster. / A growing trend of cloud-based services can be witnessed in todays information society. To implement cloud-based services a method called virtualization is used. This method reduces the need of physical computer systems in a datacenter and facilitates a sustainable environmental and economical development. Cloud-based services create societal benefits by allowing new operators to quickly launch business-dependent services. Virtualization is applied by a so-called Hypervisor whose task is to distribute cloud-based services. After evaluation of existing scientific studies, we have found that there exists a discernible difference in performance and functionality between different varieties of Hypervisors. We have chosen to perform a functional and performance analysis of Hypervisors from the manufacturers with the largest market share. These are Microsoft Hyper-V Core Server 2012, Vmware ESXi 5.1.0 and Citrix XenServer 6.1.0 Free edition. Our client, the Swedish armed forces, have expressed a great need of the research which we have conducted. The thesis consists of a theoretical base which describes techniques behind virtualization and its applicable fields. Implementation comprises of two main methods, a qualitative and a quantitative research. The basis of the quantitative investigation consists of a standard test system which has been defined by the limitations of each Hypervisor. The system was used for a series of performance tests, where data transfers were initiated and sampled by automated testing tools. The purpose of the testing tools was to simulate workloads which deliberately affected CPU and I/O to determine the performance differences between Hypervisors. The qualitative method comprised of an assessment of functionalities and limitations for each Hypervisor. By using empirical analysis of the quantitative measurements we were able to determine the cause of each Hypervisors performance. The results revealed that there was a correlation between Hypervisor performance and the specific data transfer it was exposed to. The Hypervisor which exhibited good performance results in all data transfers was ESXi. The findings in the qualitative research revealed that the Hypervisor which offered the most functionality and least amount of constraints was Hyper-V. The conclusion of the overall results uncovered that ESXi is most suitable for smaller datacenters which do not intend to expand their operations. However a larger datacenter which is in need of cloud service oriented functionalities and requires greater hardware resources should choose Hyper-V at implementation of cloud-based services.
