Crossplane consulting and hands-on support

Crossplane is an open-source Kubernetes extension that provisions and manages cloud infrastructure using Kubernetes-style APIs. Platform engineering and DevOps teams use it to standardize Infrastructure-as-Code workflows, enable self-service provisioning, and improve governance across multiple environments and cloud providers.

It typically runs inside a Kubernetes cluster and lets teams define higher-level “composite” resources that map to underlying managed services, then expose those abstractions to application teams through familiar Kubernetes tooling and CI/CD pipelines.

• Provision and manage cloud resources declaratively from Kubernetes
• Define reusable platform abstractions with compositions and policies
• Support multi-cloud and hybrid patterns through provider integrations
• Enable consistent self-service workflows with RBAC and GitOps-friendly APIs

Crossplane is a Kubernetes extension for provisioning and managing cloud infrastructure using Kubernetes-style APIs. It is used to standardize infrastructure delivery, enable policy-governed self-service, and keep infrastructure lifecycle management aligned with Kubernetes operations.

• Manages infrastructure as Kubernetes resources via CRDs and controllers, so teams use the same declarative workflow for infra and application workloads.
• Defines higher-level platform APIs with Composite Resources and Compositions, enabling reusable infrastructure products instead of one-off modules.
• Enables self-service through Claims, letting application teams request approved infrastructure without direct access to provider credentials or low-level settings.
• Continuously reconciles desired state, reducing drift and improving reliability compared to one-time provisioning and manual changes.
• Integrates cleanly with GitOps, since infrastructure definitions can be reviewed, versioned, and promoted via pull requests as Kubernetes manifests.
• Applies governance using Kubernetes-native controls such as RBAC, namespaces, quotas, and admission policies for separation of duties and compliance.
• Improves portability by separating consumer-facing APIs from provider implementations, allowing backend cloud services to change while keeping stable interfaces.
• Supports multi-cloud and hybrid management from a single control plane through Crossplane providers, reducing tooling sprawl across environments.
• Exposes status, events, and health through standard Kubernetes tooling, improving day-2 operations, troubleshooting, and auditability.

Crossplane is a strong fit when Kubernetes is the operational control plane and the goal is to offer standardized infrastructure building blocks with consistent governance. Trade-offs include operating additional controllers and providers, plus a learning curve around composition design, packaging, and API conventions.

Common alternatives include Terraform, Pulumi, and AWS CloudFormation. For implementation details, see the Crossplane documentation.

Our experience with Crossplane helped us build repeatable platform patterns, composition libraries, and day-2 operational practices that make cloud infrastructure provisioning consistent through Kubernetes APIs, with stronger governance, reliability, and cost control across environments.

Some of the things we did include:

• Designed and deployed production Crossplane control planes on Kubernetes, including upgrade runbooks, version pinning, and backup/restore approaches for configuration state.
• Built Composite Resource Definitions (XRDs) and Compositions that exposed opinionated “platform APIs” (databases, buckets, queues, networks) with sane defaults, quotas, and guardrails for application teams.
• Standardized provider configuration for AWS, Azure, and GCP with least-privilege IAM, clear environment separation, and consistent secret handling aligned to cluster standards.
• Implemented GitOps delivery for providers, packages, and configurations using Argo CD, including promotion flows across dev/stage/prod and drift detection for composition changes.
• Integrated Crossplane configuration changes into CI/CD with GitHub Actions, adding validation gates, policy checks, and controlled rollouts for composition updates.
• Hardened runtime security with RBAC, namespace isolation, restricted egress to cloud APIs, and secret management patterns that reduced credential sprawl.
• Established observability for controllers and managed resources using Prometheus, with alerts for reconciliation failures, provider throttling, and composition errors.
• Implemented multi-tenant patterns (claims, compositions, and provider configs) to safely support multiple teams on shared clusters without cross-environment leakage.
• Planned and executed staged migrations from Terraform-based workflows to Crossplane, including resource ownership strategies, import constraints, and rollback plans to reduce risk.
• Tuned performance and reliability by reducing reconciliation churn, addressing noisy diffs, right-sizing controller resources, and handling cloud provider API rate limits.

This experience helped us accumulate significant knowledge across Crossplane use-cases—from platform API design and GitOps delivery to day-2 operations—and enables us to deliver high-quality Crossplane setups that are secure, observable, and maintainable for clients.

Some of the things we can help you do with Crossplane include:

• Assess your current Kubernetes and Infrastructure-as-Code posture and deliver a written review with risks, gaps, and prioritized recommendations.
• Define an adoption roadmap for Crossplane-based self-service, including operating model, ownership boundaries, and rollout milestones.
• Design and implement providers, compositions, and claims to standardize cloud resource provisioning across teams and environments.
• Build reusable composition libraries and reference platform patterns that enforce consistency, naming, tagging, and lifecycle controls.
• Integrate Crossplane with GitOps workflows for versioned infrastructure changes, approvals, and safe promotion between environments.
• Implement security and compliance guardrails with RBAC, policy controls, and least-privilege provider credentials to reduce blast radius.
• Improve reliability with observability for reconciliation health, drift detection, alerting, and operational runbooks for incidents.
• Optimize cost and governance through ownership tagging, budget-aware defaults, right-sizing patterns, and automated cleanup policies.
• Troubleshoot provider failures, composition errors, and reconciliation loops to restore predictable provisioning and reduce toil.
• Enable platform and application teams with hands-on training, templates, and documentation to accelerate safe self-service adoption.
