The Theme of Windows Server 2016One word …

Cloud

Inspired by Azure

Easier management

Service availability

Feedback has shaped WS2016

• WS2012 and WS2012 R2

• WS2016 Preview



Hyper-VMore features

Connected Standby support

Discrete Device Assignments (DDA)

Virtual machine binary configuration

VM version

Resilient Change Tracking



Nested VirtualizationHyper-V inside of Hyper-V

Fully supported feature

Enable Hyper-V inside a VM

Requires host & VM to run:

• Windows 10

• WS2016

Great for:

• Learning

• Demo

• Training

Really for Hyper-V containers



Windows Server Containers & Hyper-V ContainersModern service deployment

A new way to deploy services in a cloud

• No longer 1 app per server

Instant deployment from a repository

• Meet demand immediately

Deployed in VM or on physical machine

Windows Server Containers

• Shared kernel

Hyper-V Containers

• Isolation via Hyper-V



OperationsMaking day-to-day life easier

Hot Add/Remove of memory and virtual NICs

Hyper-V Manager slight improvements

Integration services via Windows Update

VM version



Production CheckpointsReacting to how people really use Hyper-V

Everyone has horror stories about Hyper-V “snapshots”

• Were never recommended in production

• Degraded performance

• Misused as backup (“snapshot”)

• Widely used

We now have:

• Standard checkpoints: what we always had

• Production checkpoints: the new default

Production checkpoints

• Recommended for production systems

• Uses backup to create the checkpoint

• Applying the checkpoint = restoring from backup



PowerShell DirectEasy admin of VMs

You don’t always have network access to a guest OS

• Deliberate/accidental disconnection

• Firewalled VLANs

• Software-defined networks

How do you perform tasks in the guest OS for tenants?

PowerShell Direct is remoting via the VMbus

• From the host

• Via the hypervisor

• VM networking is not used

Requires:

• Windows 10/WS2016 host/VM

• Guest OS credentials

• Hyper-V administrator rights on the host



SecurityHardening the hypervisor and cloud

Host Resource Protection

Linux secure boot



Guarded FabricWhere can your VMs run?

Hypervisor has been hardened

A new attestation service:

• Host must be authorized to start a VM

Host Guardian Service

• Key/attestation service

• Runs in dedicated physical domain

Two models

• Admin-trusted: easy to deploy & good for PoC

• TPM-trusted: more secure

TPM-trusted

• HGS requires HSM

• Hosts require TPM 2.0 and UEFI 2.3.1 with secure boot



Shielded Virtual MachinesWho can see inside your VMs?

“I cannot put my data in a cloud”

• “I don’t know who will access my data”

Solution:

• Don’t limit your flexibility

• Limit your threats: encrypt!

Shielded virtual machines:

• Virtual TPM: BitLocker that you control

• Optionally limit access to the guest OS

Two levels of shielding:

• Encryption supported: Trusted admins

• Shielded: Non-trusted admins



AvailabilityImproving uptime

Cloud Witness

Site-aware failover clusters

Virtual machine start order

Improved diagnostics

Workgroup & multi-domain clusters



Cluster Rolling UpgradeEnable easier “upgrades” to newer versions of Hyper-V

Huge amount of legacy Hyper-V out there

• No upgrade process

• Too complicated/expensive to migrate

“Upgrade” WS2012 R2 (only) to WS2016

Process:

1. Drain host of VMs

2. Evict host from cluster

3. Rebuild host with WS2016 and configure

4. Join rebuilt host to old cluster

5. Repeat steps 1-4 for each host

6. Upgrade cluster to WS2016 functional level



Compute & Storage ResiliencyOvercoming transient errors

A cluster prioritizes data integrity

• Storage issues -> stop the service

• Brief glitch -> VM guest OS blue screen

A cluster uses network heartbeat to detect outages

• Network outage -> failover the service

• Brief glitch -> reboot that takes longer than glitch recovery

Compute resiliency:

• Cluster is more tolerant of network timeouts

• Hosts are isolated without failover

• “Flapping” hosts are quarantined (Live Migration)

Storage resiliency:

• A disk timeout causes the VM to pause

• Resumption of storage causes the VM to resume



StorageCommodity storage gets faster and more available

Storage Replica

Storage quality of service

Deduplication improvements

SMB 3.0 improvements



Storage Spaces Direct (S2D)SATA storage with a virtual SAS bus

Storage Spaces without SAS hardware

Build a Scale-Out File Server without:

• SAS HBAs

• SAS cables

• JBODs

S2D cluster:

• Servers with internal disks

• Working as 1 storage system

• CSVs span servers

• Shared to Hyper-V hosts via SMB 3.0

Use SATA disks to reduce costs

• Flash (SSD or NVMe): persistent cache

• HDD: mirror + parity for performance + capacity



Storage Spaces Direct (S2D)Hyper-converged infrastructure

Classic virtualization architecture:

• Compute: Hyper-V

• Network: iSCSI, FC(oE), SMB 3.0

• Storage: SAN, SOFS

If storage + compute = servers …

Hyper-converged infrastructure

• Flatten it all

• 1 tier of inter-connected servers

• Includes storage in the servers

Simpler than you think:

• CSVs deployed on Storage Spaces

• VMs are storage on CSVs

• No file shares!



NetworkingRedefining software-defined networking

Network Function Virtualization (NFV)

Virtual switch improvements

Software-defined encapsulation



Network ControllerA fabric ported from Azure

Replacing SCVMM as the point of SDN management

Centralized role to configure the entire network stack

• Virtual switches

• NVGRE / VXLAN

• NFVs

Realistically:

• For very large deployments

• Deployed by SCVMM

• Managed by Microsoft Azure Stack



The ability to deploy Azure in your own public/private cloud

The user interface and management

• Azure Portal (“Ibiza”)

• Azure Resource Manager (ARM)

• PowerShell

A huge investment by Microsoft

An alternative to the complicated Windows Azure Pack (WAPack)

Microsoft Azure StackAzure on your terms
