AWS Programmes Fail Quietly — Until Go-Live
The three failure modes that derail AWS programmes — and how independent QA stops them before they reach production.
Security Misconfiguration
AWS security failures are rarely caused by broken services — they’re caused by misconfigured IAM policies, overly permissive S3 buckets, and unintended public exposure. Cloud migrations create many new configuration decisions. Independent security testing validates the posture before go-live, not after a breach.
Data Pipeline Integrity
Migrated workloads depend on data pipelines that are rebuilt rather than moved. Transformation logic, data loss at boundaries, and schema changes all create integrity failures that don’t surface without systematic data validation testing — especially when the source system is still live and in parallel.
Performance Under Cloud-Scale Load
On-premise load testing results don’t predict cloud performance. Auto-scaling, cold start behaviour, regional latency, and service limits create failure modes that only appear under realistic production load patterns. Performance testing must be designed for the cloud architecture — not inherited from legacy approaches.
How Resync Approaches AWS Testing
AWS cloud migrations and cloud-native development programmes require a different approach to QA. Infrastructure is code. Environments are ephemeral. Scale, availability, and security properties are tested, not assumed. The failure modes are different from on-premise — and so is the discipline required to find them.
Resync’s cloud QA specialists validate AWS workloads across the full stack — from infrastructure configuration and security posture through to application behaviour, data pipeline integrity, and performance under cloud-scale load. We work independently from your AWS partner, providing the objective assurance layer that migration programmes require.
For NZ organisations lifting and shifting critical workloads, or building cloud-native products on AWS, independent QA is how you know the platform is actually ready before you cut over.
What We Test
Our specialist team covers the full testing scope — from functional validation to performance, integration, and regression.
Cloud Migration Testing
Validate lift-and-shift and re-platform migrations — verifying application behaviour, data integrity, and performance match or exceed the source environment.
Security & Compliance Testing
Test AWS security configurations, IAM policies, network controls, and compliance posture — independently, before production exposure.
Performance & Load Testing
Validate auto-scaling behaviour, latency profiles, and throughput under realistic NZ production load patterns on AWS infrastructure.
Data Pipeline & Integration Testing
Test AWS data pipelines — Glue, Kinesis, S3 — for completeness, transformation accuracy, and resilience to upstream failures.
Infrastructure as Code Testing
Validate AWS CloudFormation and Terraform templates — testing that infrastructure configurations deploy correctly, security controls are enforced, and environments are reproducible.
End-to-End Migration Validation
Verify complete application behaviour post-migration — functional parity with the source environment, user acceptance across all critical workflows, and production readiness sign-off.
Tool Independence
We Recommend the Right Tool.
Not the One We’re Paid to Sell.
Most QA partners are certified resellers — their tool recommendation follows their vendor agreement, not your programme needs. Resync has no vendor sales targets. We select and deploy whichever testing platform best fits your technology landscape, your team’s skills, and your budget. That objectivity is part of what independence means.
Why Resync for AWS?
Independent. Specialist. Accountable.
Truly Independent
No AWS vendor relationship. No implementation partnership. We are accountable only to you — which means our findings are always honest.
Specialist Domain Teams
Our AWS testers bring deep platform knowledge combined with enterprise QA discipline. They know the platform and they know where the risk hides.
Outcomes, Not Hours
We measure success by defects prevented, deployment confidence gained, and risk reduced — not by test case volume. You get results that hold up under pressure.
Frequently Asked Questions
What programme directors and CIOs typically ask before engaging Resync for AWS quality assurance.
Q.What does AWS migration testing cover?
Resync’s AWS migration testing covers the full quality scope: functional verification that applications behave identically to source environments, data integrity validation across migrated datasets, security posture testing of the new cloud configuration, integration testing of all connected services, and performance validation under production-representative load. We validate the cloud environment is production-ready — not just deployed.
Q.How do you test AWS infrastructure as code?
Infrastructure as Code introduces testable states that traditional testing approaches don’t cover. Resync validates CloudFormation and Terraform templates for security policy enforcement, correct resource provisioning, and environment reproducibility across accounts and regions. We also validate deployment pipelines for correct build, test, and release gate behaviour.
Q.Can Resync help with AWS Well-Architected Review preparation?
Yes. Resync’s cloud QA work naturally aligns with the AWS Well-Architected Framework pillars — particularly operational excellence, security, reliability, and performance efficiency. Our testing coverage produces evidence that supports Well-Architected Review findings and remediation validation.
Q.Do you test AWS-native services or just migrated applications?
Both. Resync tests migrated application workloads for functional and performance parity, and also validates AWS-native services — Glue, Kinesis, Lambda, RDS, API Gateway — for correct behaviour, error handling, and resilience. Cloud-native architectures introduce failure modes that only systematic testing discovers.
