Session objectives and takeaways Tech Ready 15 6/17/2018 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! © 2012 Microsoft Corporation.

Why IaaS under ARM? Managed Disks Virtual Machine Scale Sets 6/17/2018 11:35 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. © 2014 Microsoft Corporation.

Migration steps Validate Commit OR Abort Prepare Check manually 6/17/2018 11:35 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 © 2014 Microsoft Corporation.

Difference between Data Plane and Control Plane 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 Read more https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-windows-migration-classic-resource-manager https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-windows-migration-classic-resource-manager-deep-dive/ Azure Datacenter © 2011 Microsoft Corporation.
