Gold Winner for Data Center Innovations for 2017 Golden Bridge awards for an Azure Migration we completed

3. Moving an existing data center to Azure
Agenda
Moving an existing data center to Azure
Converting a Monolithic Application to PaaS

4. Moving an existing data center to Azure

5. Moving an Existing Data Center to Azure
A new client wanted to move their entire legacy data center to cloud
Data center consisted of several traditional legacy applications which required migrations
No applications were cloud ready
Most technology was 10+ years out of date

6. 10 years of 1st party applications which run the business
“Legacy” Technology
SQL Server 2005
SQL Server 2000
AX 4
Exchange 5.5
Windows 2003
Windows XP
10 years of 1st party applications which run the business

7. Migration Approach Combination of PaaS and IaaS was used Office 365
Outlook to replace Exchange
SharePoint and OneDrive to replace File Servers
SQL 2014 to replace SQL 2005
SQL DB to replace SQL 2000
Windows 2012 R2 to replace Windows 2003
Dynamics 365 to replace AX4*

8. Different Technologies for Different Problems
Different applications had different problems
Cloud has no one size fits all solution
Each problem requires a slightly different solutions
Legacy applications like AX4 can present unique challenges

9. How we did the migration
Configured site to site VPN
Built new Active Directory Domain Controllers
SQL Server Log Shipping
Built new web/application servers and reinstalled
Pointed new web and application servers to new database server, completed database migration
Changed Public DNS

10. The End Result COO was happy CFO was happy CEO was happy
Cloud budget was 20% less than new hardware & software
Final implementation was 10% less than budgeted
COO was happy
CFO was happy
CEO was happy

11. Converting a Monolithic Application to PaaS

12. Existing Application Target 1TB database running in Azure DS13 VM
Database Server CPU running at capacity
Web tier running in VMs is hard to deploy to
No control of data locality
All data exists in SQL Server today

13. Biggest Challenges What to do with all the data?
SQL DB
Cosmos
Azure Data Lake
Make deployments easier
Need continuous deployment
Deployment method needs to include database solution
Geo-locality
Customer data needs to be in the customers region
Customer needs to be in control
Easy migration options

14. How we are doing the migration
Moving authentication into its own database
Work with end customers for Azure region selection
Migrate LOB data into Azure Data Lake
Build and populate new customer tables in authentication database
Build and execute SSIS packages to move end customer data into PaaS SQL DB databases
Build web app in various regions world wide to support customers.
Deploy traffic manager in front of web apps. Migrate DNS from VM farm to traffic manager

15. The End Result
Ask me next year
So far it’s going well

16. Biggest takeaway for every project
There is no one correct Azure solution
Some projects need IaaS, some PaaS, some SaaS
Some need a combination
Some need all 3
