Infrastructure Testing
Crossplane lets you build a platform API on top of Kubernetes — your developers claim a PostgreSQLInstance, your platform delivers an RDS instance. But testing that pipeline, from XRD to provider to real cloud resource, requires a different approach than testing regular Kubernetes operators. This post covers Crossplane provider testing: unit
Infrastructure Testing
Crossplane extends Kubernetes to manage cloud infrastructure resources — AWS, GCP, Azure, and others — using Kubernetes custom resources. Crossplane Compositions define how high-level platform abstractions (like "a PostgreSQL database with backup enabled") translate into provider-specific resources (like an RDSInstance and an S3Bucket for backups). Testing Crossplane compositions
Infrastructure Testing
CloudFormation templates are JSON or YAML files describing AWS infrastructure. Unlike application code, you can't run unit tests against infrastructure templates the same way — the only way to know for certain that a template deploys correctly is to deploy it. But several tools give you meaningful validation before
Infrastructure Testing
Pulumi manages infrastructure using general-purpose programming languages — TypeScript, Python, Go, C#, Java. This means Pulumi programs benefit from the same testing infrastructure as application code: unit tests, integration tests, and CI/CD pipelines. Pulumi's policy-as-code system, CrossGuard, extends this to compliance testing: you write policies
Testing
CDK for Terraform (CDKTF) lets you define infrastructure in TypeScript, Python, Go, or Java and synthesize it to Terraform JSON. This brings software testing practices to infrastructure: unit test your constructs, snapshot test synthesized output, and run integration tests against real cloud resources. This guide covers CDKTF testing from construct-
AWS CDK
Writing CDK constructs that deploy working infrastructure is the easy part. Writing CDK constructs that deploy secure infrastructure — that's where teams struggle. CDK Nag is a static analysis tool that checks your CDK stacks against security and compliance rules before a single resource is deployed. This post covers
AWS
CloudFormation templates grow from 50 lines to 5000 lines. They define VPCs, IAM policies, RDS instances, and load balancers.
Testing
A game day exercise is a structured event where an engineering team deliberately causes failures in their own systems — and then observes, learns, and improves from the experience. It's the practice that turned Netflix into the company that wrote Chaos Monkey, that AWS uses before every major infrastructure
Testing
Business continuity testing is not just for disaster recovery — it's about systematically validating that your organization can maintain critical operations under a wide range of adverse conditions. Unlike DR testing (which focuses on technical recovery), BCT covers the full picture: technology, people, processes, and communication. This checklist is
Testing
Your database going down is not a matter of if — it's when. A disk fills up, a cloud provider has an AZ outage, a runaway query corrupts an index, a network partition isolates the primary. The question is whether your failover mechanism works correctly and whether your application
Testing
Kubernetes is designed for resilience — but resilience requires testing.
Testing
Most disaster recovery plans have never actually been tested. They exist as documents — carefully written, officially approved, and completely unvalidated.
