Quality Engineering
Cloud TestingValidate behavior across cloud environments, not just localhost.
"Works on my machine" dies in the cloud. We test applications in their real AWS, Azure, or GCP environments, configuration, scaling behavior, failover, and the environment-parity gaps that cause production-only bugs.
What this covers
Environment-parity and configuration Testing across dev/stage/prod
Scalability and auto-scaling behavior validation
Failover, backup, and disaster-recovery Testing
Cloud-cost-aware test environment strategy
Multi-region and latency behavior checks
The environment is part of the product
A cloud application is not just its code.
A cloud application is not just its code. It is the code plus autoscaling policies, load-balancer health checks, IAM boundaries, managed database failover, message queue retry semantics, secrets rotation, and infrastructure defined as code that can drift from what is deployed. Most of those behaviours are never exercised by functional Testing, which means they are exercised for the first time during an incident.
Cloud Testing verifies the behaviours that only exist in a distributed, elastic environment: what happens when an instance is terminated mid-request, when a dependency times out, when a queue backs up, when a scale-out event arrives ninety seconds after the traffic did. We work primarily on AWS, and the same discipline applies on Azure and GCP.
What we exercise
Elasticity: does autoscaling trigger at the right threshold, provision fast enough to matter, and scale back down without dropping in-flight work?
Resilience: instance termination, availability-zone loss, managed database failover, and dependency timeouts, verified rather than assumed.
Configuration parity: whether staging genuinely resembles production, and whether infrastructure as code matches what is actually deployed.
Identity and access: IAM roles and policies tested against least privilege, including what a compromised service role could reach.
Data durability: backup integrity and restore rehearsals, because an untested backup is a hypothesis.
Cost behaviour: the spend curve under load, so a resilience win does not arrive as a surprise invoice.
Failure injection, controlled
The only way to know how a system fails is to make it fail on purpose, in a controlled window, with an owner watching and a rollback ready.
The only way to know how a system fails is to make it fail on purpose, in a controlled window, with an owner watching and a rollback ready. We start small, a single dependency latency injection in a non-production environment, and expand scope only as confidence and observability improve. Paired with Performance Testing, this turns 'we think it is highly available' into evidence with a timestamp.
Engagement path
How the engagement runs
Every Cloud Testing engagement runs the same way: understand the risk, build the thing that reduces it, prove it works, hand it over.
Architecture and risk review
We map services, dependencies, scaling policies and failure domains, and identify which failure modes have never actually been observed.
Environment parity check
Infrastructure as code compared against deployed reality, and staging assessed for the differences that would invalidate a test result.
Resilience and scale exercises
Controlled instance termination, failover, dependency latency injection and scale events, each with a defined blast radius and rollback.
Restore rehearsal and reporting
Backup restore timed end to end, findings written up with remediation, and the useful checks left behind as repeatable pipeline steps.
Deliverables
What you get
Artefacts you keep and can run without us. Everything lives in your repositories and your tooling.
Handover pack
6 artefacts · yours to keep
A documented map of failure domains and untested failure modes
Environment parity findings between staging, production and infrastructure as code
Autoscaling and failover results with timings, not assumptions
IAM least-privilege findings with concrete policy recommendations
A timed backup restore rehearsal you can show an auditor
Repeatable resilience checks wired into your pipeline where practical
Self-check
Signs your team needs this
If more than one of these is true, it is usually cheaper to fix now than after the next release.
High availability is in the architecture diagram but has never been tested
Staging and production have drifted and nobody knows by how much
Backups run nightly and a restore has never been rehearsed
Autoscaling policies were set once, at launch, and never validated
Cloud spend moves unpredictably when traffic does
