Why are customers choosing to move their SQL
Server workloads to AWS?
“We concluded that migrating to AWS would be the most cost-
effective strategy, and the agility of the AWS Cloud model fit our
SQL Server workloads perfectly. The Ven.ue platform has definitely
benefited from the scalability and performance of AWS, so that gave
us a lot of confidence.” – Mike Gassner, Sr. Vice President, Technology
Solutions, Sony DADC New Media Solutions
“A lot of our SQL Server workloads can push 15,000 IOPs
continuously, for long periods of time. We really liked the
performance and value we saw in the Amazon EC2 I2 instances.” –
Randy Young, Director of Cloud Operations, Infor
