Depending on your business goals—whether they are maximizing control, offloading administration, or eliminating commercial licensing—AWS offers four distinct strategic paths. The New Standard ### Oracle Database@AWS For organizations running mission-critical workloads on **Oracle Exadata** who require the same performance, scalability, and availability found on-premises. * **Business Benefits** Unified experience with collaborative support, single invoice, and Oracle Support Rewards. * **Technical Edge** Sub-millisecond latency access from EC2 to Exadata infrastructure. * **Modernization** Zero-ETL integration with Amazon Redshift for real-time analysis. Fully Managed ### Amazon RDS for Oracle If your goal is to focus on application development rather than "undifferentiated heavy lifting," this fully managed service automates tasks. * **Automation** AWS manages installation, provisioning, patching, and upgrades. * **High Availability** Multi-AZ configuration with synchronous replication and automatic failover. * **Licensing Flexibility** License Included (Standard Edition) or Bring Your Own License (BYOL). Maximum Control ### Oracle on Amazon EC2 For workloads that require full control over the database environment and underlying operating system. * **Infrastructure Sovereignty** Full root access to OS and Oracle binaries. Use your own tools. * **Customization** Ideal for specific versions, legacy features, or custom patches. * **Performance Tuning** Leverage EBS-optimized instances for dedicated throughput. Modernize Path ### Move to Open Source Eliminate commercial licensing costs and vendor lock-in by refactoring to AWS-native engines. * **Amazon Aurora Serverless** Auto-scaling for variable or unpredictable workloads. * **Amazon RDS for PostgreSQL** Highly performant, open-source engine with managed benefits. * **Migration Support** Use AWS SCT and AWS DMS to automate conversion and migration. Migration Engine ## The Science of Zero Downtime. We don't guess. We engineer. From AWR baselines to reverse-sync cutovers, every step is mathematically verified. PHASE 01 ### Baseline & Capture We don't just look at schema. We capture **AWR reports** and peak workload patterns (IOPS, CPU, Memory) to establish a mathematical baseline for performance regression testing. \> aws sct create-project --source-engine ORACLE ... PHASE 02 ### Convert & Remediate Automated schema conversion using **AWS SCT**. We manually refactor complex PL/SQL logic, utilizing pg\_partman for partitioning and pg\_cron for scheduling. PHASE 03 ### Sync (CDC) We engage **AWS DMS** with Change Data Capture. The source (Oracle) feeds the target (AWS) in real-time. We monitor replication lag metrics to ensure sub-second latency. PHASE 04 ### Tune & Regress We replay captured production traffic against the new environment. We tune **Auto-Vacuum** and memory indicators until performance matches or exceeds the baseline. PHASE 05 ### Cutover The final switch. We implement **Reverse Replication** as a safety net, allowing instant fallback to Oracle if needed (it won't be). ## Decision Guide Which Path is Right for You? REQUIREMENT Oracle Database@AWS RDS for Oracle Oracle on EC2 Move to Open Source Control Level Managed Infrastructure Fully Managed DB Full OS/DB Access Cloud-Native Managed Best For Exadata Performance Lowering TCO Deep Customization Cost Elimination Licensing BYOL / Private Offer LI or BYOL BYOL Only Open Source / No License High Availability Oracle RAC Multi-AZ (Automated) Self-Managed Aurora Replicas ## The Migration Toolkit Reliable migrations aren't magic; they are engineering. We leverage AWS native tools to ensure data integrity and zero-downtime cutovers. ### AWS SCT (Schema Conversion Tool) SCT is our "x-ray" for your database. It automatically converts schema objects (views, stored procedures, functions) to the target format. #### Key Deliverable: Assessment Report We generate a detailed "Action Plan" that highlights exactly which objects convert automatically (typically >90%) and acts as a scope of work for the remaining manual conversion. ### AWS DMS (Database Migration Service) DMS handles the movement of data. It supports homogeneous (Oracle to Oracle) and heterogeneous (Oracle to Aurora) migrations. #### Key Feature: CDC Replication **Change Data Capture (CDC)** reads from the transaction logs (Redo Logs) to replicate changes in real-time, keeping the target database in sync until the final cutover window—ensuring **zero downtime**. ### Not Sure Which Path is Right for You?

You have options. You can "Bring Your Own License" (BYOL) to EC2 or RDS to maximize current investments. Alternatively, you can switch to "License Included" (Standard Edition) or refactor to open-source to eliminate them entirely. ### Do you handle the actual migration? Yes. We are an end-to-end partner. We handle the assessment, schema conversion (SCT), data migration (DMS), performance tuning, and cutover execution. ### Can we really migrate without downtime? Yes, effectively zero. We use AWS DMS with Change Data Capture (CDC) to keep the target database in sync with production. Actual cutover only requires a brief window for application pointer updates (often < 5 minutes). ### Will performance suffer on AWS? No. We architect for IOPS. By leveraging io2 Block Express volumes and dedicated instances (r6i/x1e), we can match or exceed on-premises performance, even for demanding Exadata workloads. ## Ready to Cut Costs and Modernize?
