The DevOpsification of Windows ServerJeffrey SnoverMicrosoft Technical FellowChief Architect Enterprise Cloud Group@JSNOVER

What is DevOps?

DevOps is about culture and processes

DevOps is NOT about tools and

technology

But…..

This is wrong

Tools and technology

play a critical role

Tools and technology can make DevOps

easy or hard

Windows Server 2016 is architected to make DevOps easy

Windows Server 2016 resolves the interface between devs and ops

Windows Server has been silent on the interface between Devs and Ops

• No architecture• 1,000 blossoms bloomed

1,000 conflicts also bloomed

WS2016 resolves that interface

• Traditional ops model• Emerging ops model using Containers

Zero-footprint model Server Roles and Optional Features live outside of Nano ServerStandalone packages that install like applications

Key Roles & FeaturesClustering, Hyper-V, Storage (SoFS), and DNS ServerIIS, .NET Core, and ASP.NET Core

Full Windows Server driver supportAntimalware optional packageSystem Center VMM and OM agents available

Nano Server: Optimized for the Cloud Era

Nano Server – PowerShell Core• Refactored to run on .NET Core• Full PowerShell language compatibility & remoting• Invoke-Command, New-PSSession, Enter-PSSession, etc.

• Most core engine components• Support for all cmdlet types except workflow• C#, Script, and CIM

• Limited set of cmdlets initially• Growing fast

DevOpsification of Windows• Componentization• Development• Packaging & deployment• Configuration• Containers & Docker • Operational Validation Testing• Operating Securely

Nano Server has a full developer experience, unlike Server CoreWindows SDK & Visual Studio 2015 target Nano ServerRich design-time experience

Project template, full IntelliSense, error squiggles, etc.

Full remote debugging experience

Nano Server - Developer Experience

First a word about MSI• Not supported on Nano Server• MSI has GUI dependencies

• Custom Actions are the portal to hell

Windows Server App installer(WSA)

• New declarative Server installer• Extends the AppX schema• Allows for Server-specific extensions, such as NT

Services, Perf Counters, COM Objects, WMI providers, ETW events

• No custom actions• 4 out of 5 kittens love WSA

Write once, deploy anywhere

… but admins are often not suspected of criminal activity – they are simply targeted because they control access to networks the attacker wants to infiltrate.

“Who better to target than the person that already has the ‘keys to the kingdom’?”

You’re an Admin

Thanks, you’re PWND!!

Problem: system admin privileges

Safe functions required by role

Dangerous functions attackers could abuse

Just Enough Admin Allows you to perform administrative

tasks without being a full administrator

• On a Server - almost any administrative action requires a user be an administrator• Once an administrator, a user can do anything on the server with no oversight• A compromised machine or a breached administrator account enables attacker movement to other assets
