Parium cloud assessments put candidates into environments where the problem is a firewall rule, a load balancer health probe, or an IAM policy. The kind of thing that takes down production services and requires someone who understands how cloud networking actually works, not just how to describe it on a whiteboard.
The skills that matter when a 503 hits production at 2am and the answer is buried somewhere between the NSG rules, the probe configuration, and the backend pool binding.
Each scenario replicates a realistic cloud infrastructure failure. Candidates get access to a simulated cloud environment with CLI tools and must diagnose and resolve the issue.
An Azure VM behind a Standard Load Balancer is returning 503 errors. The health probe is failing but the application is running. The issue sits between the NSG rules, the probe configuration, and the backend pool binding. Tests whether the candidate can trace the full request path through Azure networking.
A deployment pipeline has stopped working after an IAM policy change. Service accounts can't pull images, health checks are failing, and new pods won't start. The candidate traces the permissions chain across service principals, role assignments, and resource scopes.
A cloud-hosted ML inference service has degraded. GPU-backed VMs are healthy but the service is returning errors. The issue involves a combination of cloud networking (peering, load balancing) and GPU service configuration. Tests cross-domain troubleshooting: cloud infra meets GPU workloads.
Services in a peered VPC can't reach each other after a network change. Route tables, security groups, and NACLs all look correct individually but the traffic isn't flowing. Candidate needs to understand how VPC peering routes propagate, where asymmetric routing breaks, and how to verify end-to-end connectivity.
An internal certificate has expired, causing a chain of TLS failures across services. Some endpoints return 502, others timeout. The candidate must identify which certificate expired, understand the trust chain, and determine the fastest safe remediation across multiple services that depend on the same CA.
Running a specific cloud architecture? Multi-region with Traffic Manager? Hub-and-spoke VNets? Custom Terraform modules? We can build scenarios around your exact cloud topology, your networking patterns, and the failure modes that actually affect your team.
