Session Objectivesand Key Takeaways


Session Objectives

• Steps for successful Windows Azure IaaS migration

• Scoping, Planning, Discovery, Estimation

• Recommended Approaches

• Lessons and Experiences from real world large scale migrations.

• Understand the tools and processes available


Key Takeaway

Better understanding of how to migrate your workloads to Azure IaaS


Top of Mind Questions – Ice BreakersWhy should I move to Azure ?What can I move to Azure ?What will change when I move to Azure ?Will it be supported any differently ?How much will it cost to move ?How much will it cost to operate ?


Some more Ice Breakers

Will everything I have on premise run in Azure IaaS ?Probably Not

Will my other vendors support their app running in Azure IaaSDo Not Assume So Verify !

Will clustering and failover work exactly the same ?Verify!

Planning for Performance


Planning for HA, DR and Backup• Affinity Groups• Availability Sets• SQL Server Always On• Azure Backup service


Planning for Security– Windows Firewall

– Barracuda solution

– Network ACLs

– Security for Windows Azure IaaS Virtual Machine:

• Anti-Malware and Anti-Virus

• Monitoring and Diagnostics

• Operating System Configuration

• Operating System Updates

• Resiliency and Fault Tolerance

• Secrets Management

Migration Lessons Learned

Create pre-move and post-move test plans

Downtime scheduling and communication (bandwidth)

Examine how apps are accessed (DNS, IP addr, etc.)

Reconfigure backups & test disaster recovery plan

Validate disks


Skills Needed

• Understanding the Azure account and subscription model• Understanding of Azure IaaS objects

– Cloud Services– Virtual Networks

• Address space, subnets• DHCP• DNS

– VPN• Static or Dynamic gateway and model specific limitations


Skills Needed

– Storage Accounts– Affinity Groups– Availability Sets– End points, ACL and Load Balancer– Proficiency in all products being migrated must exist in

the team– General Networking, Storage– PowerShell (the portal is limited!)– Experience in domain migrations
