Session objectives and takeaways
At the end of this session, you should be
better able to…
Why IaaS on Azure Resource Manager?
Know how to get to IaaS on Azure Resource Manager
Know the tools that will help on this journey
If you know more at the end of the session than when you came in, then I consider it a success!

3. Why IaaS under ARM? Managed Disks Virtual Machine Scale Sets
6/17/ :35 AM
Why IaaS under ARM?
Managed Disks
Higher availability, security
Virtual Machine Scale Sets
Hyper-Scale to 1000 VMs
Unified Azure Stack
One single model to interact with the Microsoft Cloud
Enhanced Compute Capabilities
3 fault domains and 20 update domains
Increased Scalability
Increased Subscription Scale
Increased throttling scale
Decoupled network model
Clean separation of compute and network concepts
Network model resembles traditional physical devices
Reduced locking semantics
Massively parallel deployment of virtual machines
Instance Metadata Service
Scheduled Events
Accelerated Networking, AZs etc.

6. Migration steps Validate Commit OR Abort Prepare Check manually
6/17/ :35 AM
Migration steps
Validate
Prepare
Check manually
Commit OR Abort
1. Validate - Validate if resource is capable of migration
2. Prepare – Start migration and create shallow resources in ARM stack
3. Check – Check if created shallow resources in ARM stack are equivalent to those in ASM stack
4a. Commit – Apply changes into the ARM stack and change the pointers to deep resources to ARM stack OR
4b. Abort – Delete the created shallow resources in ARM stack

Microsoft Services
6/17/2018
Difference between Data Plane and Control Plane
Control Plane Operations
Operations involves to management plane
Create a VM
Restart a VM
Update Virtual Network with a new subnet etc.
Data Plane Operations
Any operation that doesn’t go through the Azure Management plane
Accessing a web site
Copying a blob from a storage account
Accessing a Public IP address to RDP or SSH into the Virtual Machine.
Application Users
IT Admin
Data Plane Operations
e.g. Access Web Server on IaaS VM, RDP into a VM
Control Plane Operations
e.g. Add a Data Disk, Restart a VM
Available during migration
Not available during migration 
VM API under ARM
Restart VM
Add a Data Disk
