Key to this consistent platform is a set of common technologies and capabilities that extend across those three datacenters.
+ Flexible development allows your organization’s developers to use their choice of tools, languages – Microsoft or open source – and open standards to quickly build apps, connect them with other apps and data, and then deploy on premises, in the cloud or in a hybrid model. Visual Studio and Team Foundation Server enable application lifecycle management, from the idea to deployment of an app.
+ Unified management with System Center and Windows Intune gives your administrators a single pane of glass to manage applications, systems and devices across private, hosted and public clouds.
+ Active Directory and Windows Azure AD provide a powerful base for single identity across clouds to securely extend applications to people and their devices.
+ Integrated and portable virtualization, built into Windows Server, allows your team to virtualize not just servers, but also the network, storage and applications across clouds.
+ Last but not least, a complete data platform powered by SQL allows you to manage petabytes of data, power mission critical applications and give businesspeople BI solutions with a range of tools – Excel all the way up to Hadoop.
So, what does the Cloud OS mean to IT organizations?
It means your organization can shift to more efficiently managing datacenter resources as a whole, including networking, storage and compute. You will be able to deliver powerful apps that boost employee productivity and delight your customers much, much faster across private, hybrid and public clouds. Further, it means you can manage data, both big and small, to extract the story it has to tell for your business. And you will be able to give employees personalized experiences with apps and data on virtually any device, while maintaining security and compliance.
