Customers are migrating their workloads to AWS
Verizon is migrating over 1,000 business-critical applications and database backend systems to AWS,
several of which also include the migration of production databases to Amazon Aurora.
By migrating from Microsoft SQL Server to Amazon Aurora, Ryanair can run one of the largest email
campaigns in Europe with higher performance at a fraction of the cost, sending out 22 million
emails daily to customers.
Trimble migrated their Oracle databases to Amazon RDS and project they will pay about 1/4th
of what they paid when managing their private infrastructure.
Intuit migrated from Microsoft SQL Server to Amazon Redshift to reduce data-processing timelines
and get insights to decision makers faster and more frequently.
Equinox Fitness migrated its Teradata on-premises data warehouse to Amazon Redshift. They went
from static reports to a modern data lake that delivers dynamic reports.
Migrated their Market Data system from SQL Server to Aurora MySQL using AWS Database Migration
Service(DMS) to replicate data nightly. Reduces their processing times from 8 hours to 3 hours.
By December 2018, Amazon.com will have migrated 88% of their Oracle DBs (and 97% of
critical system DBs) moved to Amazon Aurora and Amazon DynamoDB. They also migrated their
50 PB Oracle Data Warehouse to AWS (Amazon S3, Amazon Redshift, and Amazon EMR).
Samsung Electronics migrated their Cassandra clusters to Amazon DynamoDB for their Samsung
Cloud workload with 70% cost savings.
