absurd from an application’s perspective. With Aurora, the maximum read

migrate and/or replicate your databases and data warehouses
to AWS
AWS Schema Conversion Tool (SCT) convert your commercial
database and data warehouse schemas to open-source engines
or AWS-native services, such as Amazon Aurora and Redshift
We’ve migrated over 30,000 unique databases

Approaches to transforming...
Salesforce
Workday
Replacement
Bespoke
Archive
eCommerce Customer –
Move and nibble away
Media Customer –
Move, stabilise and transform
De-risk legacy infrastructure and
burning platforms once again and then
move to a managed database on EC2,
then ’nibble away’ at the functionality
by replacing is piece by piece with
SaaS, bespoke replacement software
or by retiring or arching part of the
systems
De-risk legacy infrastructure then use
AWS tools to migrate and translate the
database into the new platform.
Development tools and migrations are
faster within AWS making
transformation quicker within the
cloud than attempting a migration and
transformation in one hit
