The document provides an overview of Microsoft's cloud operating system stack and its components. It discusses the architecture of Azure Pack and System Center, which includes the virtual machine manager, networking, storage, hypervisor and automation. It describes how these components work together to provide a software-defined infrastructure that can run workloads for multiple tenants. The document also highlights demonstrations of storage management, software-defined networking and service management automation.

2. Session Objectives
o Get overview of Microsoft Cloud OS stack
o Understand the different components involved and
see them in action
o Hear deployment experiences from the Field
o Have a lot of fun ….and get questions answered

3. The Cloud OS
Modern platform for the world’s apps

4. Cloud – Demystified
• Pool of compute, storage and networking
• Allocable on demand to your customers
• Automate everything
• Metered
• Self-service

10. The Performance vs. Cost Dilemma

11. Microsoft Software defined Storage
Storage Spaces / Scale out File Server
• Cost effective and performant
• Ease of Management
• Scalable
• Auto Tiering (SSD / HDD)
• Write Back Cache

12. Scale the Storage Stack

InfiniBand
• Higher performance
through offloading of
network I/O processing
onto network adapter
• High throughput with
low latency and ability to
take advantage of high-
speed networks (such as
InfiniBand and iWARP)
• Remote storage at the
speed of direct storage
• Transfer rate of around
40 Gbps on a single NIC
port
• Compatible with SMB
Multichannel for load
balancing and failover
*Remote Direct Memory Access *e.g. Mellanox Connect X3®™ Adapter Family

18. Microsoft Networking
Cloud Providers are required to…
… isolate Tenants from each other
… isolate Tenants from Provider Infrastructure
… be flexible for changes on physical Infrastructure
… offer Self Service Capabilities to tenants

19. Why Network Management is Important

20. SCVMM 2012 Networking
Logical Networks
Physical Network Infrastructure
Network Sites
Network Sites / VLANs
IP Pools
IP Address Pools for deployment

21. SCVMM 2012 R2 Networking
Logical Networks
Physical Network Infrastructure / Sites / IP Pools
VM Networks
Virtual Networks for VMs
Port Profiles
New Features from Windows Server 2012 Hyper-V
Logical Switch
Logical Network Switch which combines all features

22. How network virtualization works
• Overlays multiple virtual networks on
shared physical network
• Uses industry standard General Routing
Encapsulation (NVGRE) protocol
Problems solved
• Creates VM mobility across datacenter,
hoster cloud or Azure without network
constraints
• Provides ability to import customer IP
addresses and network topology
• Helps remove VLAN constraints
• Helps eliminate hierarchical IP address
assignment for virtual machines

27. Multi-Tenant HNV Gateway
• Virtual Machine running Server 2012 R2 with RRAS
Role
• On "dedicated" Hyper-V Host
• 50 S2S VPNs / 200 virtual Subnets per single GW
• Service Template for Scale Out / Redundancy
• Support for Site-to-Site VPN with 3rd Party Products
from Cisco, Juniper, Citrix

31. Microsoft Hyper-V 2012 R2
• Gen2 VMs
• Enhanced Session Mode
• vRSS / dVMQ
• Online VHDX resizing
• Hyper-V Replica Cycles
• …etc

32. Hypervisor Management

35. Admin Portal

36. Tenant Portal

37. Automation

38. Automation….
… is a key component in every cloud
… must leverage standard APIs and interfaces
… must support multiple tenants
… must support linear scaling

39. Architecture
• REST oData API / Web Service
• Portal integrated with Azure Pack
• SQL Database
• Runbook Workers
Windows Azure Pack Admin Portal
