Rebroadcast: Webinar for Infrastructure Managers: Challenges and Solutions for Migrating Oracle On-Premises to AWS

## The Unresolved Challenges of Oracle Database
While Oracle Database supports the backbone systems of many enterprises, it often faces issues stemming from long-term operation, such as rising operational costs, difficulties in system upgrades, and increasingly complex requirements for performance and availability. As cloud and AI adoption become key management priorities, database infrastructure requires options that balance cost optimization with future scalability rather than simply maintaining the status quo. However, the optimal solution for Oracle DB operations is often unclear, and many organizations miss opportunities for improvement by continuing to make decisions based on traditional on-premises assumptions.

## Architecture and Key Points of Oracle AI Database@AWS
When considering [Oracle AI Database@AWS](https://www.ashisuto.co.jp/cloud/aws/service/oracle-database-at-aws.html), it is essential to first clarify which operational responsibilities shift to the cloud and which remain in-house compared to on-premises Oracle DB. The database cannot be placed directly within an existing AWS VPC; instead, it resides on a dedicated network for Oracle Database@AWS, requiring a designed "peering" connection to communicate with internal systems and existing VPCs. While configurations are primarily managed via the AWS console, the underlying architecture utilizes Oracle Cloud Infrastructure (OCI) mechanisms, necessitating occasional status checks within OCI. Availability strategies also differ; while Oracle RAC provides redundancy within a single site, extending this to multi-AZ equivalent levels requires configuring Data Guard. Furthermore, cloud-native operational issues—such as DNS resolution, failover procedures, support channel division (AWS vs. Oracle), and monitoring strategies—increase, making it crucial to clarify uncertainties during the initial planning phase.

## Expert Support from AWS/OCI Engineers
This seminar organizes the representative challenges of Oracle DB operations and explains the perspectives necessary for TCO comparison and preparing materials for internal decision-making. We introduce points for considering Oracle AI Database@AWS not only for cost reduction but also for long-term operational and migration success. Additionally, specialized AWS/OCI engineers share insights on key considerations for the entire lifecycle, from migration planning to ongoing management, providing practical tips to advance realistic migration plans and operational improvements.
