What is Windows Server Software-Defined Datacenter?
Software-Defined Datacenter (SDDC) is a common industry term that generally refers to a datacenter where all of the infrastructure is virtualized. Virtualization is the key, and it simply means that the hardware and software in the datacenter expand beyond a traditional one-to-one ratio. With a software hypervisor emulating hardware, operating systems and applications can be abstracted away from physical hardware, and multiplied to form elastic resource pools of processors, memory, I/O and networks.
Microsoft's implementation of the SDDC consists of the Windows Server technologies highlighted in this article. It starts with the Hyper-V hypervisor that provides the virtualization platform upon which networking and storage are built. Security technologies, developed for the unique challenges of virtualized infrastructure, mitigate internal and external threats. With PowerShell built into Windows Server, and the addition of System Center and/or Operations Management Suite, you can program and automate provisioning, deployment, configuration and management.
The technologies built into Windows Server and System Center are the main building blocks of the Windows Server SDDC experience. But even though it's a virtualized platform, it still requires the right hardware underneath. Microsoft partners participating in the Windows Server Software-Defined (WSSD) Solutions program can help your enterprise acquire the right hardware and get it up and running on day zero.

Storage Quality of Service
Centrally monitor and manage storage performance for virtual machines using Hyper-V and the Scale-Out File Server roles, improving storage resource fairness between multiple virtual machines.
Storage QoS is built into the Microsoft software-defined storage solution provided by Scale-Out File Server and Hyper-V using SMB3 protocol. A new Policy Manager provides central storage performance monitoring.
Storage Replica
Disaster recovery and preparedness make possible zero data loss, with the ability to synchronously protect data on different racks, floors, buildings, campuses, cities, and countries with more efficient use of multiple datacenters.
Synchronous Replication
- Application writes data
- Log data is written and the data is replicated to the remote site
- Log data is written at the remote site
- Acknowledgement from the remote site
- Application write acknowledged
t & t1 : Data flushed to the volume, logs always write through

Guarded fabric
As a cloud service provider or enterprise private cloud administrator, you can use a guarded fabric to provide a more secure environment for VMs. A guarded fabric consists of one Host Guardian Service (HGS) - typically, a cluster of three nodes - plus one or more guarded hosts, and a set of shielded virtual machines (VMs).

Shielded VMs
The data and state of a shielded VM are protected against inspection, theft and tampering, from both malware and datacenter administrators.
- Shielded VMs will only run in fabrics designated as owners of the VM.
- Shielded VMs are encrypted by BitLocker, or other means, so that only designated owners can run them.
- Running VMs can be converted to shielded.
Host Guardian Service
Host Guardian Service holds the keys to legitimate fabrics, as well as encrypted virtual machines.
