2 Cloud OS LIAB Keynote Deck – October 2013
高一物理 必修1 Cloud OS LIAB Keynote Deck – October 2013 3.7 探究  Enterprise-grade Platform We understand your existing IT systems and challenges better than any technology company out there. IDC predicts that 70% of CIOs will embrace a cloud-first strategy in To get there, organizations need to move at their own pace over a number of years, with many living in a hybrid environment for quite some time. That flexibility – to live in both worlds – even with a cloud-first strategy – is non-negotiable. (Source: IDC CIO Agenda webinar). So, we aren’t going to tell you to move everything to the cloud. We’ll help you take what you have, upgrade through our Cloud OS strategy and take the journey with you. Some vendors are making this transition more confusing by calling feature-limited apps “cloud-ready” or force you to use different sign-ons for every online experience or won’t even guarantee continuous availability. Cloud shouldn’t mean lowering your expectations or making compromises. Microsoft believes you shouldn’t expect any less from the cloud – you should expect more. It MUST be an enterprise-grade platform  Hybrid Design By design, our hybrid cloud builds commonalities into the platform, unifying resources across premises to let data and apps flow freely. Hybrid is the core of Microsoft’s Cloud OS vision. We’re uniquely able to take a hybrid cloud approach to deliver unified compute, storage and networking across a customer’s datacenters, the public cloud and hosted clouds – creating a single application, data and device management platform. You benefit from a common and consistent approach to development, management, identity, virtualization and data – spanning on-premises to cloud – your cloud, a service provider cloud and Microsoft’s cloud This gives you the ability, from a one view, to manage apps and data beyond your own private cloud – to a partner cloud – to a public cloud – in a consistent way. Helps you be very flexible in thinking about how you deploy your apps across the multitude of cloud environments  People-focused Approach Our people-focused approach means IT professionals, developers and users can leverage existing skills in this new hybrid world. For years, Microsoft has been delivering experiences that appeal to end-users driving maximum productivity, regardless of location or device. Microsoft brings that same focus on people to IT and developers – mirroring the familiarity and ease-of-use from our on-premises products into our Cloud services. The unifying technologies in the Cloud OS enable the flow, management and governance of data and apps across premises and devices to keep employees productive and connected, wherever they are (IT professionals, developers and users). This all leads to higher satisfaction – from employees to IT – and improved productivity with lower training costs. With such a large solution and developer footprint – adoption by our enterprise customers speaks for itself – and is also a huge driver of our focus on people and their experiences  (ADDITIONAL OPTIONAL HYBRID DETAILS NOT IN NOTES SLIDES) This is powerful because we will deliver a flexible development environment for the developer so that it can code once and deploy anywhere; deploy on premises, deploy out to a partner cloud, deploy out to Azure cloud. But they only have to write the app once on the power of our .NET framework. Unified management is our ability to use System Center, sitting in your datacenter to administer all the automation scripts to manage and pool the resources of that datacenter. Well while you’re looking in that pane of glass, to be able to provision and move VMs, objects, data from your datacenter out through a service provider or out to Azure for bottomless storage, for redundancy, for disaster recovery. Common identity is a third element of our consistent platform, using Active Directory group policies that you’ve already set up in your enterprise. You merely get the benefit of those group policies extended through Active Directory Federation Services and Azure based Active Directory, so that the group policies you set, extend out to the cloud automatically. You don’t have to manage multiple federation common identity across different clouds. Integrated virtualization is a fourth area. You no longer have to have a third part bolt on to virtualize your compute. Not only are we giving you compute capability, virtualization of your compute capability imbedded in Windows Server, we’re giving that to you around software defined networking and around virtualization of storage, also. Lastly, being able to have a complete data platform where your data can reside anywhere across these three clouds in a seamless way is a value proposition that’s huge as well. You can optimize your storage costs in this dimension. All that capability integrated in how we think about the complete data platform for a customer across all clouds. 条件 物体三力平衡的 授课教师：徐宜强
