Six options for migrating Oracle RAC to AWS. But which one fits your environment?

In this tech article, our expert Aisar Sabateen compares managed and self-managed architectures, from Amazon RDS to EC2 with Data Guard, FlashGrid and VMware Cloud, each with different implications for licensing, Oracle support and recovery targets.

Not every option is Oracle-supported. Understanding that distinction before you commit could save significant cost and risk.

What does migration discipline actually look like when you stop treating it as a project?

Governance that's maintained, not filed. Dependency mapping updated as environments shift. Cutover plans built around failure scenarios, not just success. Rollback procedures tested and ready, with defined trigger points.

The gap between knowing this matters and consistently operationalising it is where most migrations still fall short.

When standard migration methods each fail against specific constraints - database size, bandwidth, platform compatibility, the conclusion is often that the migration itself is too risky.

But that's a methodology problem, not a migration problem.

Evaluating approach against actual constraints rather than defaulting to conventional tools changes what's possible. What appears inherently risky becomes an architectural challenge with a solvable path.

In this case study, we explore how this shift in evaluation changed the outcome for a healthcare provider migrating a 12TB Oracle database to Azure:

We're heading to the Conference 2026 this month

We're proud to be a Silver Sponsor of this community event, and that's not all…

Our Cloud and Solutions Architect, Eugene Bobkov, will be taking the stage in Sydney on 30 October to talk about building production-grade high availability for PostgreSQL.

He'll break down a real-world HA architecture using Patroni, etcd and Barman, covering everything from synchronous replication and split-brain protection to cross-region disaster recovery.

Our team members Josh Woolston and Sheridan Wright will also be there, joining conversations on the latest in the PostgreSQL world.

We hope to see you there!

How to ensure success with Agentic AI deployments? Focus on practical guardrails and intelligent architecture to prevent cost blowouts.

Implementing controls such as using varied LLMs for different tasks, setting usage limits, and containerising workloads are crucial steps. Opting for controlled environments also ensures predictable costs.

A private, containerised AI setup can significantly reduce the annual subscription expenses many organisations face, offering better security and control.

Ensure your AI strategy prioritises business value and cost optimisation from the start.

Don’t rely on upgrades to fix performance.

A major SQL Server upgrade exposed severe degradation caused by underlying bottlenecks.

It’s a reminder that upgrades should be approached as a way to validate performance, not improve it by default. Understanding system behaviour and addressing root causes early is key to avoiding disruption.

Cloud migration's real challenge starts after go-live.

The real work begins post-migration. Many SMBs overlook continuous optimisation and crucial change management, leading to cost creep, performance issues, and user adoption challenges.

A clear direction for ongoing monitoring, performance tuning, and comprehensive staff training is essential to realise the full, sustained value of your cloud investment and ensure success.

There is no one-size-fits-all Oracle RAC migration to AWS.

The best architecture depends on your specific availability targets, licensing position and Oracle support requirements.

In this tech article, our expert Aisar Sabateen explains the trade-off at the centre of this decision: the two options with the fastest recovery time are not Oracle-supported, while the four Oracle-supported options require accepting longer RTO or moving away from RAC.

Understanding this trade-off before you commit is what separates a successful migration from a costly one.
