Many organizations that use Google Cloud also want to run workloads in their own data centers, factory Ųoors, retail stores, or even in other public clouds.  \nHowever, operating multiple Kubernetes clusters has its own diũculty and overhead in terms of consistent conůguration, security, and management. For example, manually conůguring one Kubernetes cluster at a time creates risks, and it can be challenging to see exactly where errors are happening.  \nGKE Enterprise is Google's cloud-centric container plaŴorm for running modern apps anywhere consistently at scale. GKE Enterprise can help organizations by providing a consistent plaŴorm that lets them:  \n● Modernize applications and infrastructure in-place.  \n● Create a uniůed cloud operating model (single pane of glass) to create, update, and optimize container clusters wherever they are.  \n● Scale large multi-cluster applications as Ųeets- logical groupings of similar environments-with consistent security, conůguration, and service management.  \n● Enforce consistent governance and security from a uniůed control plane.  \nGKE Enterprise helps you increase operational consistency in governance and security and developer velocity while reducing cost, deployment risk, and operational complexity. Speciůcally, GKE Enterprise helps with the following areas:  \n● Customers who want cloud-like experience on-premises or are looking for a uniůed solution while migrating their applications to cloud (GKE Enterprise hybrid environment).  \n● Google Cloud customers who want to beŵer manage their containerized applications (GKE Enterprise on Google Cloud).  \n● Customers who want to solve multicloud complexity with a consistent governance, operations, and security posture (GKE Multi-Cloud).  \nThe following diagram shows a high-level overview of GKE Enterprise in a hybrid environment. GKE Enterprise can help with Kubernetes compliance and governance, security, and operations, along with multi-cluster automation and conůguration. Kubernetes clusters managed by GKE Enterprise can then run on-premises, in Google Cloud, or in another cloud provider:  \nPage 5 of 41  \nThis reference architecture provides opinionated guidance to deploy GKE Enterprise in a hybrid environment to address some common challenges that might face.  \nIn this reference architecture, the term cluster means a Kubernetes cluster managed by GKE unless stated otherwise.
