Introduction<\/h2>\n\n\n\n<p>GKE on AWS is a Google Cloud service that lets you create and operate Google Kubernetes Engine (GKE) clusters that run on Amazon Web Services (AWS) infrastructure\u2014while being managed through Google Cloud tooling and APIs.<\/p>\n\n\n\n<p>In simple terms: your Kubernetes worker nodes (and your application pods) run in your AWS account, but you manage the cluster lifecycle and day\u20112 operations using Google Cloud\u2019s GKE experience (Console, APIs, IAM, fleet management, and policy tooling).<\/p>\n\n\n\n<p>Technically, GKE on AWS is part of Google Cloud\u2019s distributed, hybrid, and multicloud portfolio (historically associated with Anthos \/ GKE Enterprise). It provisions Kubernetes clusters on AWS (using AWS networking and compute primitives) and connects them back to Google Cloud for centralized management, governance, and observability.<\/p>\n\n\n\n<p>The problem it solves: many organizations want consistent Kubernetes operations across Google Cloud and AWS\u2014without forcing an immediate migration, rewriting platform tooling, or running self-managed Kubernetes everywhere. GKE on AWS provides a practical path to standardize cluster lifecycle management, policy, and operations across clouds.<\/p>\n\n\n\n<blockquote>\n<p>Naming note (important): Google previously used names such as <strong>Anthos clusters on AWS<\/strong> and <strong>GKE Multi-Cloud<\/strong> in documentation and UI. The current product name in Google Cloud documentation is <strong>GKE on AWS<\/strong>. If you see older names in existing environments or scripts, treat them as legacy naming and verify the latest workflow in official docs.<\/p>\n<\/blockquote>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">2.

FAQ<\/h2>\n\n\n\n<p>1) <strong>Is GKE on AWS the same as running GKE in Google Cloud?<\/strong><br\/>\nNo. GKE on AWS runs worker nodes in AWS and is managed via Google Cloud, but it is not identical to GKE on Google Cloud. Feature sets and integrations can differ.<\/p>\n\n\n\n<p>2) <strong>Do I need an AWS account to use GKE on AWS?<\/strong><br\/>\nYes. Your clusters run in your AWS account, and AWS resources (EC2, VPC, load balancers, storage) are billed by AWS.<\/p>\n\n\n\n<p>3) <strong>Do I pay Google Cloud, AWS, or both?<\/strong><br\/>\nBoth. You typically pay Google Cloud for the GKE on AWS management\/software component and AWS for the underlying infrastructure.<\/p>\n\n\n\n<p>4) <strong>What skills do operators need?<\/strong><br\/>\nYou need working knowledge of Kubernetes plus practical familiarity with both Google Cloud (IAM, projects, APIs) and AWS (IAM, VPC, EC2, load balancers).<\/p>\n\n\n\n<p>5) <strong>How do upgrades work?<\/strong><br\/>\nUpgrades are managed through Google Cloud\u2019s GKE on AWS workflows, but you must follow the supported version paths. Always review the version and upgrade docs for your release.<\/p>\n\n\n\n<p>6) <strong>Can I use the same kubectl and Kubernetes manifests?<\/strong><br\/>\nYes for standard Kubernetes objects. But cloud integrations (ingress, storage classes, IAM integration) may require AWS-specific configuration.<\/p>\n\n\n\n<p>7) <strong>How do I expose services publicly?<\/strong><br\/>\nTypically via Kubernetes <code>Service<\/code> type <code>LoadBalancer<\/code> which provisions an AWS load balancer, or via an ingress controller pattern. Verify the supported ingress\/load balancer controller approach in docs.<\/p>\n\n\n\n<p>8) <strong>Where do my logs and metrics go?<\/strong><br\/>\nIt depends on how you configure observability. You may use Google Cloud\u2019s Cloud Logging\/Monitoring, AWS CloudWatch, or a third-party stack. Verify supported integrations for your cluster version.<\/p>\n\n\n\n<p>9) <strong>Is there a \u201cprivate cluster\u201d option like in GKE?<\/strong><br\/>\nNetwork architecture options differ across products and versions. Verify current GKE on AWS networking and endpoint exposure capabilities in official docs.<\/p>\n\n\n\n<p>10) <strong>Can I connect multiple AWS accounts?<\/strong><br\/>\nMany organizations do (for isolation by environment or business unit), but the exact supported model and recommended patterns should be verified in official docs.<\/p>\n\n\n\n<p>11) <strong>How does identity work for developers accessing the cluster?<\/strong><br\/>\nUsually a combination of Google Cloud IAM permissions to obtain credentials and Kubernetes RBAC for namespace access. Exact integration details can vary\u2014validate for your environment.<\/p>\n\n\n\n<p>12) <strong>What are the biggest failure modes to plan for?<\/strong><br\/>\nIAM permission drift (AWS role changes), subnet IP exhaustion, AWS quota limits, and load balancer provisioning failures are common operational pain points.<\/p>\n\n\n\n<p>13) <strong>Is GKE on AWS a good choice for very small teams?<\/strong><br\/>\nIt can be, but only if you understand the dual-cloud overhead. For small teams entirely on AWS, EKS might be operationally simpler.<\/p>\n\n\n\n<p>14) <strong>Can I run stateful workloads on GKE on AWS?<\/strong><br\/>\nYes in principle (Kubernetes supports it), but you must design storage classes, PVs, backups, and failover using AWS primitives and validate supported storage integrations.<\/p>\n\n\n\n<p>15) <strong>Where should I start if I\u2019m new?<\/strong><br\/>\nStart with the official docs and a small lab cluster, then practice: credentials setup, cluster creation, node scaling, service exposure, and cleanup to understand cost and operational boundaries.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">17.

Summary<\/h2>\n\n\n\n<p>GKE on AWS is Google Cloud\u2019s managed approach to running Kubernetes clusters on AWS infrastructure while keeping cluster lifecycle management, governance constructs, and (optionally) observability aligned with Google Cloud\u2019s multi-cluster operations model.<\/p>\n\n\n\n<p>It matters because real organizations are multi-cloud: they need consistent operations, policy, and audit without forcing every workload to move clouds. In the distributed, hybrid, and multicloud category, GKE on AWS fits as a practical bridge for standardizing Kubernetes operations across Google Cloud and AWS.<\/p>\n\n\n\n<p>Cost and security success depends on understanding the dual model:\n&#8211; <strong>Costs<\/strong>: you pay Google Cloud for management\/software and AWS for infrastructure; watch load balancers, NAT, egress, and telemetry volume.\n&#8211; <strong>Security<\/strong>: design least-privilege across Google Cloud IAM, AWS IAM, and Kubernetes RBAC; maintain dual audit trails.<\/p>\n\n\n\n<p>Use GKE on AWS when you want Google Cloud\u2019s Kubernetes management model for clusters that must run in AWS. Next step: follow the official GKE on AWS quickstart for your target region\/version, then expand into fleet governance and production-grade networking\/observability patterns.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Distributed, hybrid, and multicloud<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[60,51],"tags":[],"class_list":["post-691","post","type-post","status-publish","format-standard","hentry","category-distributed-hybrid-and-multicloud","category-google-cloud"],"_links":{"self":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/posts\/691","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/comments?post=691"}],"version-history":[{"count":0,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/posts\/691\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/media?parent=691"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/categories?post=691"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/tags?post=691"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
