At Performance One Data Solutions, we’ve seen the “in-the-trenches” reality of these migrations. Success isn’t just about moving bits; it’s about choosing the right cloud ecosystem for your specific performance and compliance needs.
The Cloud Showdown: Where Should Your Oracle Data Live?
When migrating legacy Oracle environments, the big three—OCI, AWS, and Azure—offer vastly different architectures. Here is how they stack up for high-performance workloads in 2025.
-
Oracle Cloud Infrastructure (OCI): The “Native” Path
OCI is built on non-oversubscribed hardware, specifically designed for the Oracle Database.
- The Technical Edge: Only OCI offers RAC (Real Application Clusters) and Exadata Cloud Service natively. If your workload requires sub-19 microsecond latency and massive IOPS, OCI is often the only choice that doesn’t require a total application rewrite.
- The Licensing Win: Oracle rewards you for staying home. You typically get a 2:1 vCPU-to-Core mapping, effectively doubling your licensing power compared to other clouds.
-
Amazon Web Services (AWS): The Ecosystem Giant
AWS is the choice for organizations that want to integrate their database with the world’s largest suite of AI and analytics tools.
- The Technical Edge: Amazon RDS for Oracle manages the “undifferentiated heavy lifting” (patching, backups). However, for high-performance legacy systems, you often have to run Oracle on EC2 with EBS Provisioned IOPS (io2 Block Express) to get the throughput required.
- The Challenge: You cannot run RAC on AWS. You must rely on Data Guard for HA, which can increase your architectural complexity and licensing footprint.
-
Microsoft Azure: The Enterprise Hub
Azure is the logical home for companies heavily invested in the Microsoft stack (.NET, PowerBI, and Active Directory).
- The Technical Edge: With the release of Oracle Database@Azure, you can now run OCI-managed Exadata hardware inside Azure data centers. This eliminates the latency issues previously seen in multi-cloud setups.
- The “Performance One” Insight: This is a game-changer for legacy ERPs that need to stay close to their application layer but require the “grunt” of an Exadata back-end.
The Performance One Difference: Beyond the Database
Most of our competitors focus solely on the database. We call this “siloed thinking.” At Performance One, we take a Holistic Approach. A database doesn’t exist in a vacuum; it’s the heart of an ecosystem involving networking, storage, and downstream analytics.

Step-by-Step Guide: Modernizing Your Legacy Oracle Workload
Step 1: The “Deep-Dive” Readiness Assessment
Don’t just count CPU cores. You need to analyze your AWR (Automatic Workload Repository) reports to understand peak IOPS, memory pressure, and wait events.
- Pro Tip: Look for “Hidden” dependencies. Legacy systems often have hardcoded IP addresses or aging OCI/JDBC drivers that will break in a cloud network (VPC/VCN).
Step 2: License Optimization (FinOps)
In the cloud, Oracle licensing is your biggest expense. We utilize Oracle’s Authorized Cloud Environment rules to ensure you aren’t over-licensing.
- Actionable Step: If moving to AWS or Azure, remember that 1 Processor License = 2 vCPUs. If your VM has 16 vCPUs, you need 8 licenses. Performance One often recommends “Constrained-Core” instances to limit your license exposure while keeping high memory for the SGA.
Step 3: Network Architecture & Latency Mapping
Legacy applications are “chatty.” If your app server is in AWS and your DB is in OCI, that 2ms latency will feel like an eternity to your users.
- Actionable Step: Utilize OCI-Azure Interconnect or AWS Direct Connect to ensure a fat, low-latency pipe between your layers.
Step 4: The “Pilot” Migration (Mock-Go-Live)
Never move production first. We perform a “Mock Migration” using Oracle GoldenGate or ZDM (Zero Downtime Migration) to test the timing and data integrity without impacting the business.
Step 5: Post-Migration Optimization (The TSM Advantage)
Once in the cloud, our Technical Service Managers (TSMs) take over. Using COBIT-based standards, we monitor not just “uptime,” but “performance-to-cost” ratios, ensuring your cloud bill doesn’t spiral out of control.
Why 100% US-Based Support Matters
We don’t outsource your data security. In high-performance Oracle environments, communication is the #1 failure point.
- Security: Your data stays under the oversight of US citizens, simplifying ITAR, CJIS, and HIPAA compliance.
- Sync: When your database goes down at 2:00 PM EST, you need a senior architect who is in your time zone and understands the nuance of your business—not a “Level 1” tech following a script halfway across the world.
