Is Amazon EC2 is the only option for your legacy customized Oracle DB on AWS? Do you want to move your legacy Oracle DB on AWS but are not sure that Amazon RDS can handle all custom developments you have on top of your business-critical database? In this session, we discuss how Amazon RDS for Oracle can be leveraged to accommodate specifics of your legacy database in the cloud. We discuss when and how to choose between Amazon EC2 and Amazon RDS scenarios. We outline remediation and migration steps for Amazon RDS, and we share practice-proven experience on providing FTP, SMTP from Amazon RDS. We discuss instance sizing and optimization and hybrid configurations of Amazon RDS and old Oracle DBs staying on-premises.

Cloud: Why?
UK Government Cloud First policy
“When procuring new or existing services, public sector organizations should consider and fully
evaluate potential cloud solutions first before considering any other option. This approach is
mandatory for central government and strongly recommended to the wider public sector."

UK Government Digital Strategy
“But this isn’t just about saving money—the public increasingly expects to access services quickly and
conveniently, at times and in ways that suit them. We will not leave anyone behind but we will use
digital technology to drive better services and lower costs."
Francis Maude MP, 10 December 2013
