Citrix VDI Handbook - XenApp and XenDesktop 7.15 LTSR Section 1: Overview Introduction In traditional business environments, workers suffer from productivity loss in many ways, including downtime during PC refreshes, patches and updates, or simply when they are away from the office. Application and desktop virtualization centralizes apps and desktops in the datacenter, rather than on local devices. This allows IT to deliver apps and desktops to users on demand, to any device, anywhere. Take the following response from a desktop virtualization user: Experience from the Field As a remote employee for [company], I struggled every time I needed to access the company’s intranet, which forced me to VPN into the network. I also kept data on my local device because trying to access it over my broadband connection was too slow. Some coworkers did the same and lost data due to a virus, thankfully I was luckier. Depending on my mood (and the weather), changing devices and locations was a challenge as I had to have my applications and data copied to many different endpoints. I know this was unsecure, but I didn’t care because I was more concerned with flexibility. Since moving to a virtual desktop, I’m able to use any device. I’m able to work from any location. And best of all, I don’t have to worry about copying my data and applications onto all of my personal devices. Unfortunately, organizations sometimes struggle to achieve this level of success. Why does one organization succeed while another organization struggles? If we compare the factors between success and failure between desktop virtualization and other technology related projects, we see that there is little difference: 1. Lack of justification – Without a solid business reason, desktop virtualization is simply a new way to deliver a desktop. A business justification gives the project team a goal to strive towards. 2. Lack of a methodology – Many people who try and struggle to deploy a desktop virtualization solution do so because they jump right in without understanding or implementing the appropriate prerequisites. A structured methodology provides the path for the project. 3. Lack of experience – For many who embark on a desktop virtualization project, there is a lack of experience, which creates a lack of confidence in the design. Architects begin to second-guess themselves and the project stalls. Our hope is that this handbook can alleviate the anxiety associated with desktop virtualization by showing how challenges can be resolved in a manner that is technically sound, but also feasible and effective for organizations facing deadlines and other organizational challenges. Citrix has successfully employed the methodology, experience and best practices

  • Achieving Redundancy with Hosting Controller
    Perspective In the perilous world of hosting one of the most sought-after features is failover capability. Most hosting providers desire a redundant setup in order to keep their content highly available (H.A) and minimize the chances of downtime in case of a disaster. Why is Redundancy Important? Hosting businesses usually require their data-centric internet applications to be served by more than one servers in a highly available cluster. Redundancy ensures that the data of a provider is always safe and readily available. Maximizing uptime is one of the prime goals of ISPs, ITSPs, Telcos, HSPs, MSPs and other Cloud providers. Redundancy can and does help.

Toinen palvelin sijaitsi ulkoisella palveluntuottajalla ja uusi palvelin tulisi toimeksiantajan omaan konesaliin. Työssä vertaillaan kolmea eri hallintaohjelmistoa ja miten ne soveltuivat toimeksiantajan käyttöön. Tässä tutkittiin kaikkien valittavissa olevien vaihtoehtojen dokumentaatiota, jota vertailtiin miten ne täyttävät toimeksiantajan kriteerit. Hallintaohjelmistot mitä tutkittiin, olivat Hosting Controller 10, ISP-Config ja cPanel. Seuraavaksi käydään läpi, miten suunnittelu eteni, ensin siirtosuunnitelma ja sen jälkeen suunniteltiin palvelin, johon sivustojen hallintaohjelmisto asennettaisiin ja nämä sivustot siirrettäisiin. Palvelimen asennuksessa tuli esiin erilaisia haasteita ja niitä kuvataan tässä. Tämän jälkeen kuvataan, miten siirto tehtiin ja esitetään joitakin haasteita mitä todettiin siirtojen edetessä. Kuvataan ne toimenpiteet mitä tehtiin, jotta kaikki sivustot saataisiin siirrettyä. Lopuksi tarkastellaan, miten toteutus onnistui toimeksiantajan

Introduction: A Web server is a high quality computer frame that delivers or serves content, information, and other resources that can be gathered through services. One goal of having web servers is to provide Web hosting services that allows individuals and organizations to make their own website accessible via the World Wide Web. Typically, web hosts are companies that provide space on a server they own or lease for use by their clients, as well as providing Internet connectivity; which is called a data center. Some individuals and organizations, for example, have universities with their own web servers and hosting services. However, there are two kinds of web hosting, shared and unshared. Shared web hosting is where many websites reside on one web server connected to the Internet. Each site resides on its own partition, or section/place on the server to keep it separate from other sites. Those sites share the web server resources, such as CPU, memory, storage, IPs, connection, and the like. This is generally the most economical option for hosting, as many people share the overall cost of server maintenance. Information resources, in other words, have been revaluated and become incapable to be transferred across the internet.

  • Decoupling State from Control in Software-Defined Networking
    Decoupling State from Control in Software-Defined Networking Alberto Rodriguez-Natal Advisor: Albert Cabellos-Aparicio, PhD Co-Advisor: Fabio Maino, PhD Department of Computer Architecture Technical University of Catalonia This dissertation is submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Science July 2016 To my parents, to my sister and to Andrea, of course “This is how you do it: you sit down at the keyboard and you put one word after another until it’s done. It’s that easy, and that hard.” - Neil Gaiman Acknowledgements I have always thought that the acknowledgments section is the most important part of a thesis for two reasons. First because you can find the research elsewhere, but you can onlyfind the acknowledgments here. Second because while the research evolves and the results get eventually obsoleted, the people you meet along the way remain. Therefore, I have been thinking on what to put in this section for a long time. However, now that I am finally writing it down I believe that I am making no justice to the people mentioned here. I can not find the words to express the gratitude I feel towards them. What follows is only a humble attempt. As it should be, the first lines are for my advisor, Albert Cabellos. Exceptional researcher, mentor and individual. With so many PhD advisors out there, I consider myself fortunate for having ended up under his supervision. His clear vision, endless motivation and pragmatism drove me through the most challenging periods of this thesis.
