DESCRIPTION
Join us for a tour of the features that make up the new Windows Azure Virtual Machines and Virtual Networks offerings. Using demonstrations throughout, we will explain the Virtual Machine storage architecture and show how to provision and customize virtual machines, confi gure network connectivity between virtual machines, and confi gure site-to-site networks that enable true applications that span from on-premises to Windows Azure. We’ll focus specifi cally on features that enable you to create highly available Virtual Machine-based services and how to connect Virtual Machines with Cloud Services.

VM Role Virtual Machine
Storage Non-Persistent Storage Persistent StorageEasily add additional storage
Deployment Build VHD offsite and upload to storage.
Build VHD directly in the cloud or build the VHD offsite and upload
Networking Internal and Input Endpoints configured through service model.
Internal Endpoints are open by default.Access control with firewall on guest OS. Input endpoints controlled through portal, service model or API/Script.
Primary Use Deploying applications with long or complex installation requirements into stateless PaaS applications
Applications that require persistent storage to easily run in Windows Azure.

Service Level Agreements
99.9% for single role instances8.75 hours of downtime per year
What’s includedCompute Hardware failure (disk, cpu, memory)Datacenter failures - Network failure, power failureHardware upgrades, Software maintenance – Host OS UpdatesPlanned downtime – 6 day notice, 6 hour window, 25 minute downtime
What is not includedVM Container crashes, Guest OS Updates
99.95% for multiple role instances4.38 hours of downtime per year

Fault and Update Domains
Fault DomainsRepresent groups of resources anticipated to fail togetheri.e. Same rack, same serverFabric spreads instances across fault at least 2 fault domains
Update DomainsRepresents groups of resources that will be updated togetherHost OS updates honour service update domainsSpecified in service definitionDefault of 5 (up to 20)

Windows Azure Networking
Virtual Machine Names and DNS
Bring your own DNS serverUse your on-premise DNS serversDeploy a DNS server in Windows AzureUse public DNS services
Windows Azure provided DNS Resolves VMs by name within the same cloud serviceMachine names are modeled explicitly and registered in the DNS service
Full control over machine names
Protocols and Endpoints
Port Forwarded EndpointsDirect communication to multiple VMs in the same cloud app
Support for All IP-Based Protocols (VM to VM)Instance-to-instance communicationTCP, UDP and ICMP, dynamic ports
UDP Traffic Supported in WALoad-balanced incoming traffic and allows outbound traffic
Custom Load Balancer Health ProbesHealth check with probe timeoutsHTTP based probing, allowing granular control of health checks

Windows Azure Virtual Network
Your “virtual” branch office/datacenter in the cloudEnables customers to extend their Enterprise Networks into AzureNetworking on-ramp for migrating existing apps and services to Windows AzureEnables “hybrid” apps that span cloud and their premises
A protected private virtual network in the cloudEnables customers to setup secure private IPv4 networks fully contained within Windows AzureIP address persistenceInter-service DIP-to-DIP communication

IaaS and PaaS – Better Together
Physical Virtual SaaSIaaS PaaS
The Benefits of PaaS
PaaS is cheaperReason: There’s less admin and management work to doBenefit: Organizations spend less supporting applications
PaaS is fasterReason: There’s less work for developers to doBenefit: Applications can go from idea to availability more quickly
PaaS is lower riskReason: The platform does more, leaving fewer opportunities for errorBenefit: Creating and running applications gets more reliable
IaaS and PaaS Side by Side
Mixed Mode: VM and PaaS Roles in the Same Cloud ServiceSimple, secure and highly efficient method of using IaaS and PaaS side-by-side
Direct Connectivity Using Virtual NetworkingFor advanced connectivity scenarios such as Active Directory or DCOM
Connect Cloud Apps via VIPsEasily compose services by connecting public endpoints
Mixed Mode: PaaS/IaaS in the Same Cloud ServiceStrengthsWindows Azure Provided DNS
