We are in process of building POC for Azure PAAS stuffs. Migrating on prem SQL 2012 databases to Azure SQL or SQL manged instances with Always ON feature enabled.
I've read few articles and bit confused. still don't have clarity about Always On features in both Azure SQL and SQL manged instances .
"The SQL Server high-availability features Always On failover cluster instances and Always On availability groups become obsolete on the target SQL managed instance. High-availability architecture is already built into both General Purpose (standard availability model) and Business Critical (premium availability model) service tiers for SQL Managed Instance. The premium availability model also provides read scale-out that allows connecting into one of the secondary nodes for read-only purposes"
What does it mean? Could you please assist me on that? Also, what needs to be done from DB migration from on-prem to Azure PAAs.
What are the key pointswe need to consider before we migrate? I've gone through many articles and looks like we should have strong networking skills in order to migrate.
Thanks in adavance.
