(biz305) case study: migrating oracle e-business suite to aws | aws re:invent 2014
DESCRIPTION
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.TRANSCRIPT

Enterprise storage requirements
• Requires consistent performance, each application has unique requirements
• Addressed by storage layers like SSD, SAN, NAS etc..Performance
• Addressed by using RAID, Disk Backups, Tape BackupsDurability and availability
• Requires high CAPEXCost
• Often addressed by over provisioningElasticity and scalability
• Requires consistent performance; each application has unique requirements
• Addressed by storage layers like SSD, SAN, NAS, etc..
• Addressed by using RAID, disk backups, tape backups
• Requires high CAPEX
• Often addressed by over-provisioning
Enterprise storage on AWS
• Requires consistent performance, each application has unique requirements
• Addressed by storage layers like SSD, SAN, NAS etc..Performance
• Addressed by using RAID, Disk Backups, Tape BackupsDurability and availability
• Requires high CAPEXCost
• Often addressed by over provisioningElasticity 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
