With the maturity and breadth of cloud solutions, more enterprises are moving mission-critical workloads to the cloud. American Commercial Lines (ACL) recently migrated their Oracle ERP to AWS. ERP solutions such as Oracle E-Business Suite require specific knowledge in mapping AWS infrastructure to the specific configurations and needs of running these workloads. In this session, Apps Associates and ACL walk through the considerations for running Oracle E-Business Suite on AWS, including deployment architectures, concurrent processing, load balanced forms and web services, varying database transactional workloads, and performance requirements, as well as security and monitoring aspects. ACL shares their experiences and business drivers in making this transition to AWS.

Elasticity and scalability
•Provisioned IOPS, SSD, Amazon Elastic Block Store (Amazon EBS) Optimized Instances
•Built in replication across AZ; snapshots can be replicated across regions
Pay for what you use, buy vs. build
Use as little or as much as you want or need
