3 Pourquoi une stratégie d’optimisation des postes de travail ?

4 Vos interrogations Comment garder mes données et
mes applications sécurisées ? Dois-je m’orienter vers des services “Cloud” ? Comment rendre plus productifs mes utilisateurs mobiles ? Comment gérer mes coûts ? Mes employés doivent-ils utiliser leurs PC personnels pour travailler ? Comment profiter des avantages de la virtualisation ? Stratégie client riche ou client léger ? Les clients sont sur Windows XP depuis presque 10 ans. Depuis 10 ans, beaucoup de choses ont changé que ce soit d’un point de vue de l’activité de l’entreprise ou des technologies. Windows 7 est un catalyseur qui pousse les clients à reconsidérer leur poste de travail sous l’angle de l’efficacité de leurs utilisateurs où qu’ils soient tout en gérant les coûts. Les questions sont multiples: Nouvelles tendances du marché: problématiques budgétaires, sécurité des données, législation Nouvelles technologies: virtualisation, services « cloud » (Windows Azure, Windows Intune…) Nouveaux usages: mobilité des utilisateurs, PC personnels, besoins métiers des utilisateurs Infos/chiffres clés: La moitié des professionnels de l’informatique prévoit de déployer Windows 7 (Enquête de Citibank) 68% des entreprises ont des difficulté à gérer leur PC (Forrester) Les budgets IT resteront à l’identiques l’année prochaine (1% de croissance d’après le Forrester) Coût total de possession: $ par PC par an (IDC Core IO research 2007) Sécurité et conformité 56% des répondants aux enquêtes Microsoft considèrent qu’ils ont besoin d’aide pour protéger les données de l’entreprise sur leurs postes. Vol de données représente 2.3m$ tandis que le vol de matériel représente 3.8m$ (Computer Security Institute/FBI Computer Crime & Security Survey-looking for latest version of this) Perte moyenne à cause des incidents du à la sécurité a été de $234,244 in 2009 (CSI Security Survey 2009). Fraude financière qui est passé de 12% en 2008 à presque 20% Consumerisation: vous perdez vos meilleurs employés “génération digitale” si vous ne proposez pas de technologies innovantes au sein de votre organisation (vous n’imaginez pas le nombre de personnes refusant des emplois à cause d’un environnement technologique trop vieillissant) Client Computing Choices Essential Points to Land: Complexity of OS migration, specifically in the context of Windows XP Windows 7 Windows 7 is an Inflection Point: Customers are using it to think broadly about their client computing environment They now have a wide range of choices: trends in business (tightening budgets, mobility) and technology (virtualization, cloud services,) are generating questions about how best to decide Storyline: Don’t make a decision on OS migration alone: You need a full desktop strategy Customers have been on Windows XP for nearly 10 years. In that decade, many things have changed both in business and technology. Windows 7 is a catalyst that is causing customers to reconsider their client computing environment through the lens of making people productive – wherever they are -- while managing cost. Half of IT Pros are looking to deploy Windows 7 (Citibank), and two-thirds of firms expect to migrate to Windows 7 at some point (Forrester: Windows 7 Commercial Adoption Outlook). They have lots of questions about how to achieve this, like: According to IDC, the TCO of desktops can range widely, anywhere from $230 to $1320 per PC annually. Where organizations end up within this range depends on many factors, which we will discuss later in the presentation. How do I manage costs? Should employees bring their own PCs to work? Organizations are at risk of losing their brightest and most ambitious young employees if they cannot provide the computing environment the “digital native” generation is accustomed to. Although the present economic climate has shifted the balance of power in recruiting, this is temporary: the war for talent will persist. Some companies have responded to this war by piloting “Bring Your own PC” programs, which give workers more choice in what PC they use. This means IT departments focus more on access, security and data protection. This trend obviously has ramifications on TCO. Do I expand use of cloud services? Forrester believes that the increased availability and capabilities of all kinds of cloud services: from Web-based offerings to Software as a Service to Infrastructure as a service will be a game-changing, disruptive shift for some enterprise clients (Market Overview of Current Cloud Service Providers from Global IT providers-June 2009). The expansion of cloud services presents an opportunity for organizations to consider how best to leverage their existing investments and where to put new ones. Should I use Rich clients or thin clients? Lowering cost and improving manageability, security, and remote access drive interest in client virtualization (Forrester), and the choice between rich clients or thin clients often accompanies the choice about what kind of desktop virtualization organizations use. How do I keep my data safe and my applications secure? The average loss due to computer security incidents was $234,244 in 2009 (CSI Security Survey 2009). However, theft of proprietary data from mobile devices was far higher: According to the CSI/FBI Computer Crime & Security Survey theft of proprietary data from mobile devices tallied to $2.3M, while theft of customer data from mobile devices came to $2.2M. Given this, it’s no surprise that more than half of the respondents in MSFT research told us they need help protecting corporate data on laptops. The number of mobile workers overall will increase to more than 30 percent by 2011 (IDC), and 68% of the companies we surveyed struggle with the inability to manage PCs when those are not physically connected to the corporate network. Much of this difficulty is due to the complex and time-consuming methods of connecting to corporate networks when away from the office. This presents a huge challenge not only for end user productivity but also for security and data protection. How do I keep mobile users productive? How can I take advantage of virtualization? The client virtualization trend has swept many industries over the past 2-3 years, leading many IT decision makers with questions about how they can benefit from the potential of virtualizing applications or full desktops. However, with the buzz around virtualization reaching a fever pitch, analysts, such as Natalie Lambert of Forrester – warn that many have misconceptions about exactly what benefits they can hope to achieve through virtualization. (Forrester: Know Your Facts: Understanding The Realities Of Desktop And Application Virtualization July 2009) Transition: Although migrating to Windows 7 might be the issue that causes enterprises to question these things, CIOs and architects should not make a decision based on migration concerns alone, but instead think about the broader desktop strategy for their organization and for their users. All Relevant Data Points: TCO Half of IT Pros are looking to deploy to Windows 7 (Citibank Survey) $ per PC per year (IDC Core IO research 2007) Security and Compliance 68% of Enterprises struggle managing PCs (Forrester) Forrester: IT budgets will remain flat in the next year at 1% growth Theft of proprietary data from mobile devices tallied to $2.3M, while theft of customer data from mobile devices came to $2.2M. The cost of the stolen mobile hardware itself was reported at $3.8 (Computer Security Institute/FBI Computer Crime & Security Survey-looking for latest version of this) Average loss due to security incidents was $234,244 in 2009 (CSI Security Survey 2009) saw huge jumps in financial fraud: from 12 percent in 2008 to nearly 20 percent Consumerization: You lose your most ambitious employees if you cannot provide them enough computing power (anecdote of people turning down jobs bc of computing environment) 56% of respondents in MSFT research say they need help protecting corporate data on laptops

19 Remote Desktop Services & VDI Une infrastructure commune
RD Client System Center and App-V RD Session Host with RemoteApp RD Web Access RD Connection Broker RD Virtualization Host RD Gateway Connection Broker : équilibre de charge RD Gateway : passerelle pour l’extérieur de l’enteprise Portail Web : ou que je sois dans l’entreprise RD Virtualization : rôle à installer sur le srv HyperV [Build 1] – The following slide provides a high level overview of the components in RDS. We will look at the new RDSH and RDVH technologies in depth later on. Remote Desktop Session Host Server provides a similar set of functionality as Terminal Server. RD Virtual Host Server is a hyper-v based server that is used to provide VDI functions. RemoteApp and Desktop Web Access Server provides a web based interface for RemoteApp enabled applications as well as one click access to virtual desktops. Highlight that you need Windows 7 on the client to take full advantage of Desktop Connections. RD Gateway to offer secure remote access to RDS servers and infrastructure All components require an RDS licensing server Permissions and policy is stored in Active Directory [Build 2] Remote Desktop Client gets connection information from the RD Web Access Server. If the client is outside the network the client connects through the RD Gateway server, if they are internal then can connect directly to an RDSH or RDVH server. In both cases the server that the client connects to is negotiated by the RD connection Broker. The connection broker plays a central role in RDS to make sure clients get connected to appropriate resources. It also helps clients reconnect to disconnected or interrupted session, and makes sure that clients are connecting to the correct servers for VDI resources. At a high level the remote client uses the RD Gateway to obtain access to the RDSH RD Session Host and RDVH servers. The RD Connection Broker connects clients to sessions and VMs on the RDSH and RDVH servers. All Remote Desktop Servers require validation with an RD Licensing Server.

Between 25 and 30 percent of today’s workers can be classified as mobile, and these users need to be productive regardless of where they are. The capability of anywhere access for mobile workers is provided by a set of technologies that help IT both manage and give access to Data (Folder Redirection/Offline Files), Applications (Application Virtualization), and User Settings (Roaming User Profiles). The capability of Security and Data Protection is provided by BitLocker on the PC and extended to portable drives by BitLocker To Go. It is protected in transit with DirectAccess, which leverages the security advances of IP v6 and IPSec to ensure data protection. Business Continuity is achieved through these same technologies because if users need quick access to new PCs, they can simply log in with their Active Directory credentials and their data, applications, and computing environment can be provisioned to them on demand. All of this is managed end-to-end from physical to virtual and desktop to datacenter with System Center.
