AWS and Amazon RDS provide advanced features and architectures that enable graceful migration, high performance, elastic scaling, and high availability for Oracle database workloads. Learn best practices for realizing the benefits of the cloud while reducing costs, by running Oracle on AWS in a variety of single- and multi-instance topologies. This session teaches you to take advantage of features unique to AWS and Amazon RDS to free your databases from the confines of the conventional data center.

Building fast, scalable workloads on Amazon RDS

Scaling instance components Compute Capabilities vCPUs Memory Capabilities GB of RAM Network Performance MB/s (Throughput) Storage Performance I/O Throughput Max Size T2 and R3 instance support T2.large support Instance Families: T1, M1, M2, M3

Building Oracle RAC on AWS
RAC on Amazon EC2 would be useful • Test / dev / non-prod; allow testing to cover RAC-related regression cases • Scale out and back elastically; a good match for the cloud • Scale beyond the largest instances • High-RTO redundancy at the host/instance level; App continuity for near zero downtime • Test scaling limits; a given workload scales only to n nodes on RAC • Some applications “require” RAC • Some customers don’t want to re-engineer everything just to move to AWS • Customers want it!
