Virtualization has increasingly been adopted in the last decade and the usages of virtualized environments are going to be an important part of how computers are used in the nearby future. There are a lot of advantages with virtualization and different methods have been developed to make it as efficient as possible.Forsmarks Kraftgrupp were interested in the possibility of taking advantage of virtualization in their testing environment.In this report, hypervisors of type 1 and type 2 and containers have been evaluated to determine which method and what program is preferable on a server cluster of four HP ProLiant DL380 Generation 4. Because of the hardware specifications of the DL380, focus has been on virtualization programs that do not require hardware assisted virtualization.The results show that it is possible to use some of the type 2 hypervisors on the HP ProLiant DL380 Generation 4. The suggested virtualization programs are VMware Workstation or Oracle VirtualBox. .

In this report I have made various comparisons between different client solutions; a standard client solution (PC-server), to use as a comparison and look at various differences in costs against the other client solutions that I have compared, which is Windows Thin PC, Dell Wyse, Red Hat Enterprise Virtualization and FSData terminal server/thin clients. All these solutions require a form of server to work against, which also the standard solution uses, but the main difference is that most of the data and computing power is on the server instead of the client.Window Thin PC, Dell Wyse, Red Hat EV and FSData all use some kind of thin client as hardware. Some of the main differences is that Windows Thin PC can be installed on almost any hardware. Dell Wyse is a special hardware group from Dell, that uses its own proprietary software, and Red Hat EV which is based on linux, is the cheapest option where the only cost is for support. FSData terminal server/thin client use as the name suggest a terminal server and a form of thin client to connect to it, the solution essentially means that your rent the complete hardware from FSData.The comparisons are made with the view of different scenarios based of the number of clients, where costs and licenses, as well as time spent on installation, upgrades, monitoring and managing are some of the main points raised..

Den här rapporten undersöker om gränsen mellan Terminal Services och Citrix XenApp har börjat suddas ut eller om man ännu kan dra en tydlig linje mellan dessa. Detta för att avgöra om organisationer som idag kör Windows Server 2003 med Citrix XenApp enbart klarar sig med de nya funktionerna i Windows Server 2008 Terminal Services och ändå uppfylla de krav och behov en organisation har. Arbetet genomfördes rent teoretiskt. För att avgöra likheter och skillnader mellan applikationerna, så användes till största delen ett ramverk. För att kunna få en bild av hur applikationerna tillämpas rent praktiskt, användes tidigare testar samt analyser.

This analysis recommends not to use Windows Server 2008 without properevaluation in any system containing classified information. The reasons are too lowassurance and too weak authentication. If Windows Server 2008 is to be used itshould be supplemented with a stronger authentication mechanism. The installationshould preferably be of Server Core type and the server should be maximallyhardened..

This is a report of a prestudy commissioned by a medium-sized Swedish company before an imminent major change in IT systems. The change aims to provide a simplified IT administration within the company through a cloud-based approach.The preliminary study provides an interpretation of the concept of cloud computing. It also covers a review of different models to use in order to achieve an internal cloud. Suggestions on how to proceed with the change process are also provided, and which models might be appropriate for the specific company..

I dagens läge saknas en sammanställning av hur servervirtualisering är implementerat och hur det fungerar hos olika verksamheter i Sverige. Detta arbete har därför, genom en enkätundersökning, besvarat frågeställningen: "Hur ser servervirtualiseringen ut hos kommuner och landsting i Sverige?" Resultaten visade bl.a. att servervirtualisering är väl implementerat av kommuner och landsting i Sverige. Resultaten var dessutom väldigt lika mellan dessa organisationer.

The purpose of the study was to identify and analyse the implications of client virtualisation in company environments. The study chose to focus on the aspects of the current hardware, license management, application management, maintenance work and the implications virtualization would have on these. The work in the study was chosen to limit itself to a Windows environment.The background to the study was due to a growing need to be more flexible and mobile in company environments and in collaboration with the University of Jönköping a problem description and the framing of questions was defined. The essay tooka qualitative initiative to comprehend the complexity of the problem at hand. The empirical data was collected from interviews, literature studies and laboratory work testing applications.

This thesis has been carried out in cooperation with a company which develops mobile sensor platforms. The sensors measure different types of data such as temperature, pressure etc.. They will communicate through the internet with a server that stores data in a database. This system will be controlled and monitored through a web page. The project's aim has been to develop this system and to implement a server, a database, a website and a client application that simulates sensor signals.

Målet med detta projekt var att hjälpa IT-Mästaren att kunna fakturera sina kunder på ett smidigare sätt. Deras dåvarande lösning av kundernas dataanvändning var tidskrävande och ineffektivt, därför ville de automatisera systemet. Det nya systemet skulle användas för att administrera kundernas servrar med hjälp av ett grafiskt gränssnitt och sedan kontakta dem för att få fram olika värden för respektive kund som ska presenteras på IT-Mästarens hemsida. På så sätt skulle de kunna fakturera sina kunder på ett mer effektivt sätt och även få bättre överblick av kundernas användning. I och med utvecklingen utav detta system så fördjupande jag mig dels i egna kända områden men jag lärde mig också nya kunskaper. Det gällde inte enbart teknisk utveckling utan också undersökning av exempelvis hämtningen av alla data som skulle göras.

Denna rapport beskriver arbetet med att utveckla en iPhone app och ett serverprogram till Mac. Programmet är tänkt att användas av besökare på festivaleroch liknande evenemang. Så de kan dela med sig av vad de ser med andrabesökare. Appen använder den inbyggda kameran för att ta bilder som sedanautomatiskt laddas upp till en lokal server om en finns tillgänglig. Serverprogrammet sparar bilderna och visar dem sedan på en skärm eller med envideo projektor eller något liknande.

An increasing number of applications are becoming more or less network based today.The traditional architecture for network based applications is client-server, but as usageof download services are going up, so is the Peer-to-Peer architecture. This report is acomparison between the Peer-to-Peer and client-server model, and can serve as a basiswhen a decision between them needs to be taken. In the report, the performancebetween the different architectures is compared in different contexts. Our basis is ageneral implementation of both architectures in a test that is derived from a previousreport. On top of this, the performance of the different architectures are measured,implemented in a gaming-context.

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

Examensarbetet behandlar en jämförelse av Server Message Block 3.0 och föregångaren 2.1 i ett befintligt nätverk. Jämförelsen utfördes i fyra laborationsmiljöer bestående av fyra operativsystem: Windows Server 2008 R2, Windows Server 2012, Windows 7 ochWindows 8. Sammanlagt har fyra tester utförts: Förstudie, Test 1, Test 2 och Test 3. Förstudien utfördes för att testa nätverksprestanda mellan två datorer. De andra testerna satte SMB 2.1 och SMB 3.0 på prov.I Test 1 ansågs SMB 3.0 prestera sämre än SMB 2.1, för att bekräfta resultaten kontaktades Jose Barreto på Microsoft.

It is more common now to purchase products and services on the Internet. More and more companies choose to sell their services and products this way. Some services and products the customers can get delivered directly to their computers. Therefore, it is important for entrepreneurs to know when they risk a permanent establishment in another country due to their Internet based activity. If the company gets a permanent establishment in the other country, the other country can tax the income which is relatable to the company?s permanent establishment.
