Q&A

3. Embracing the cloud, embrace a cloud data strategy
How will my on-premises data migrate to the cloud?
How can I make it transparent to my users?
Afterwards, how will on-premises and cloud data interact?
How can I integrate my data assets within AWS?
Can I get help moving off of commercial databases?

4. Historically, Migration = Cost, Time
Commercial data migration and replication software
Complex to setup and manage
Legacy schema objects, PL/SQL or T-SQL code
Application downtime
