eBillingHub: Assessment Recap
SQL PaaS Unsupported Data Types : NTEXT and TEXT columns needed to be converted to nvarchar(max)
External Tables : Cross database joins are not supported. Create external tables and remove the 3 part references(e.g. [dbo].[database].[table]) to make the schema compatible.
UTC Dates : Custom date function using AT TIME ZONE in all table defaults, Stored Procedures, functions etc.. to report time in regional format.
SQL Agent Jobs : Need to be converted to elastic Jobs or hosted in IaaS SQL.

25. eBillingHub : Post Migration Azure Footprint
Microsoft Azure Migration
All front end web servers and bill agent processors were migrated to Azure VMs and load balanced.
VMs share storage with Azure file storage.
Due to time constraints a new Azure VM with SQL Server was also provisioned to host SQL Agent Jobs.
IaaS : Lift and Shift
All SQL Databases were migrated to Azure SQL PaaS instances.
Single Azure SQL Server hosts all databases in an elastic pool.
PaaS : SQL Migration
