Kubernetes Gateway API consulting and hands-on support

Kubernetes Gateway API is a Kubernetes API for defining and governing traffic entry into clusters through structured resources such as GatewayClass, Gateway, and HTTPRoute. It separates infrastructure ownership from application routing, allowing platform teams to define supported gateway implementations while application teams manage routes within approved boundaries. It complements the broader Kubernetes platform rather than requiring every team to configure vendor-specific ingress objects.

Teams use Gateway API in platform engineering, DevOps, and SRE workflows to standardize HTTP and other supported traffic patterns across clusters and environments. A practical implementation can combine GitOps or CI/CD validation, namespace and RBAC controls, TLS management, route policy checks, and observability for backend health and request behavior. The same operating model can apply to managed environments such as Azure Kubernetes Service, provided the selected gateway controller supports the resources and features you require.

• Resource ownership: GatewayClass and Gateway resources can remain under platform-team control while application teams manage permitted HTTPRoute resources for their services.
• Traffic governance: Route definitions provide a consistent place to review hostnames, paths, backend references, filters, and other traffic rules before deployment.
• Safer delivery: Teams can validate manifests in CI, enforce policy through admission controls, and promote routing changes through GitOps workflows.
• Security controls: Platform operators can standardize listener configuration, TLS termination, namespace permissions, and approved gateway implementations across environments.
• Operational visibility: Gateway metrics, access logs, events, and distributed tracing help SRE teams investigate failed routes, unhealthy backends, and configuration changes.
• Day-2 operations: A production design should document controller upgrades, compatibility testing, rollback procedures, certificate rotation, ownership boundaries, and runbooks for gateway failures.

Teams use Kubernetes Gateway API when they need structured, governed traffic routing with clearer ownership between platform engineers and application teams.

• Clear separation of responsibilities: Platform teams can define approved GatewayClass implementations and shared Gateway resources, while application teams manage their own HTTPRoute objects. This reduces the need to edit one shared ingress configuration for every service change.
• More precise routing rules: HTTPRoute supports host, path, header, and method matching, along with traffic weighting and request filtering. Teams can express application routing requirements without relying on provider-specific annotations scattered across manifests.
• Governed multi-team access: Kubernetes RBAC and Gateway API attachment rules help control which namespaces can attach routes to a shared Gateway. Platform teams can provide approved entry points while application teams retain ownership of service-level routing.
• Safer TLS management: A Gateway can define listener ports, protocols, hostnames, and TLS configuration in a consistent resource model. Teams can standardize certificate references, listener naming, and ownership rules across environments instead of configuring each ingress controller differently.
• More repeatable delivery: Gateway API resources can be stored in Git and applied through the same CI/CD or GitOps workflows as other Kubernetes resources. Pull requests can review route changes, policy updates, and environment differences before they reach a cluster.
• Better operational feedback: Gateway API status conditions report whether resources are accepted, programmed, or affected by configuration problems. Operators can use these conditions with controller logs and existing monitoring to identify invalid routes, unavailable backends, and listener conflicts.
• More consistent platform design: The resource model gives teams a common interface while allowing the underlying implementation to vary by cluster or environment. This is useful when standardizing traffic management across Kubernetes clusters, including environments based on Azure Kubernetes Service.

Our practical experience with Kubernetes Gateway API helps clients design and operate governed traffic entry for Kubernetes workloads, with clearer ownership across platform and application teams, safer routing changes, consistent TLS and policy controls, and stronger day-2 operations. We support teams running Kubernetes and managed platforms such as Azure Kubernetes Service with senior engineering capacity billed by the hour, without a retainer, lock-in, or fixed-price promise.

Some of the things we did include:

• Assessing existing Ingress, Gateway API, controller, DNS, and certificate-management patterns to identify migration risks, ownership gaps, and inconsistent routing policies.
• Designing reference architectures for GatewayClass, Gateway, HTTPRoute, and related resources, with clear boundaries between platform infrastructure and application configuration.
• Implementing Gateway API resources through Terraform, Helm, or GitOps workflows, with environment overlays, review controls, and repeatable promotion between environments.
• Planning and executing migrations from legacy Ingress resources, including route compatibility checks, phased cutovers, rollback procedures, and validation of application traffic.
• Configuring TLS termination, hostname and path routing, cross-namespace access, backend references, and policy guardrails that match your security and governance requirements.
• Integrating routing changes with CI/CD pipelines and policy checks so invalid manifests, unauthorized ownership changes, and unsafe configuration updates are detected before deployment.
• Improving observability with access logs, metrics, tracing, health checks, and actionable alerts for rejected routes, certificate failures, backend errors, and controller issues.
• Creating runbooks for incident response, controller upgrades, certificate rotation, troubleshooting, and knowledge transfer so your team can maintain Gateway API operations after implementation.

Some of the things we can help you do with Kubernetes Gateway API include:

• Assess your current traffic entry architecture: Review ingress controllers, load balancers, Gateway API adoption, GatewayClass implementations, TLS configuration, HTTPRoute resources, cross-namespace references, ownership boundaries, and operational workflows, then deliver a prioritized findings report and roadmap.
• Design a Gateway API architecture: Define how platform and application teams will use GatewayClass, Gateway, HTTPRoute, ReferenceGrant, and related resources, with clear responsibilities for shared infrastructure, application routing, certificates, and policy management alongside your Kubernetes platform.
• Implement governed traffic routing: Configure Gateway API resources for host-based routing, path matching, header matching, redirects, rewrites, traffic splitting, and backend references, with conventions that keep routing changes reviewable and consistent across environments.
• Automate Gateway API delivery: Create reusable manifests, Helm values, or infrastructure code for GatewayClass and Gateway resources, and integrate validation into pull requests and deployment workflows so configuration errors are detected before they reach a cluster.
• Integrate Gateway API with CI/CD or GitOps: Organize environment-specific HTTPRoute configuration, define promotion and rollback procedures, and connect routing changes to your existing deployment process, including platforms based on Azure Kubernetes Service where applicable.
• Strengthen security and governance: Review TLS termination, certificate management, namespace boundaries, cross-namespace references, allowed routes, admission controls, and policy enforcement, then document guardrails that protect shared gateways without blocking application teams.
• Improve routing observability: Define metrics, logs, traces, health checks, and alerts for Gateway and HTTPRoute behavior, including rejected routes, backend errors, TLS failures, latency, status-code changes, and configuration drift.
• Plan migrations and upgrades: Assess a move from Ingress resources or controller-specific annotations to Gateway API, map existing routing behavior to portable resources, identify implementation-specific gaps, and prepare staged migration and rollback plans for controller or cluster upgrades.
• Support day-2 operations: Produce runbooks for route changes, certificate rotation, failed deployments, backend health issues, policy violations, incident response, and routine reviews, and work with your team to troubleshoot and refine the operating model after implementation.
