Learn how you can migrate databases with minimal downtime from on-premises and Amazon EC2 environments to Amazon RDS, Amazon Redshift, Amazon Aurora and EC2 databases using AWS Database Migration Service. We discuss homogeneous (e.g. Oracle-to-Oracle, PostgreSQL-to-PostgreSQL, etc.) and heterogeneous (e.g. Oracle to Aurora, SQL Server to MariaDB) database migrations. We also talk about the new AWS Schema Conversion Tool that saves you development time when migrating your Oracle and SQL Server database schemas, including PL/SQL and T-SQL procedural code, to their MySQL, MariaDB and Aurora equivalents. Best of all, we spend most of the time demonstrating the product and showing use cases designed to help your business.”

4. How Does the Cloud Help?
Provision a database in 6 minutes
Provision a MAZ database with a few mouse clicks
Scale a database up/down with 60-90 seconds downtime
Apply patches with 60-90 seconds downtime
Add read replicas with a few mouse clicks
Protect your backups and logs with 11 9’s of durability
Recover to any point in time from nightly backups + logs
Detailed metrics, down to 1 second intervals
Secure your data with single click encryption at rest
Amazon

5. How Can I Get to the Cloud?
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?

6. Migration Used to be Cost + Complexity + Time
Commercial data migration and replication software
Complex to setup and manage
Application downtime
Database–engine specific application code

7. Start your first migration in 10 minutes or less
Keep your apps running during the migration
Replicate within, to or from Amazon EC2 or RDS
Move data to the same or a different database engine

would require significant upfront investment in both
infrastructure and license expense.
 Wanted to migrate to Amazon Aurora
 Database Migration Service automated most of the
work and dramatically reduced the manual effort
involved in the code migration.
 Hans Wald, Chief Technology Officer, Thomas
Publishing:
 "The AWS Database Migration Service will be a
key enabler for our plans to migrate more
