Datacenter Abstraction Layer Center
Some believe the cloud is something you bolt on top of a static operating system. At Microsoft, we fundamentally disagree with this view. The issues of cloud computing are all classic operating system issues. In a recent blog post, the President of Microsoft Server and Tools Business Satya Nadella stated:
“At the most basic level, any operating system has two 'jobs': it needs to manage the underlying hardware, and it needs to provide a platform for applications. The fundamental role of an operating system has not changed, but the scale at which servers are deployed and the type of applications now available or in development are changing massively.”
Microsoft’s vision of a CloudOS is to execute these missions in the context of a data center (instead of a single server). The datacenter abstraction layer (DAL) is our work with the industry to provide a common management abstraction for all the resources of a data center to make it simple and easy to adopt and deploy cloud computing. The DAL is not specific to one operating system; it benefits UNIX cloud-computing efforts every bit as much as Windows.
The DAL uses the existing DMTF standards-based management stack to manage all the resources of a data center: physical servers, storage devices, networking devices, hypervisors, operating systems, application frameworks, services, and applications. The DAL is different than other cloud efforts in that it uses - and builds on - proven management stack technologies, instead of inventing new ones.
The figure below shows the relationship between devices, the DAL, and the applications and services that use the DAL:
Additional DAL resources
The DAL adopts the following standards:
Distributed Management Task Force ( DMTF)
Storage Networking Industry Association ( SNIA)
The Open Group ( Open Group)
International Organization for Standardization ( ISO)

With Windows Server 2012, Windows has shifted its focus to become a Cloud OS, so a new abstraction layer is required – a Datacenter Abstraction Layer or DAL. Microsoft is, once again, joining with other companies to define the DAL.
