Google Anthos is a hybrid and multi-cloud application platform developed to manage containerized workloads across on-premises and cloud environments. It integrates orchestration, service mesh, policy enforcement, and developer workflows to enable enterprises to run distributed systems with consistent tooling across providers. Anthos targets organizations seeking portability between Google Cloud Platform, Amazon Web Services, Microsoft Azure, and private data centers while leveraging technologies from the Cloud Native Computing Foundation, Kubernetes, and Istio ecosystems.
Overview
Anthos presents a unified control plane that abstracts infrastructure differences between Google Cloud Platform, Amazon Web Services, Microsoft Azure, and private VMware deployments. It builds on open-source projects such as Kubernetes for orchestration, Istio for traffic management, and Knative for serverless workloads, offering integrations with services from BigQuery, Cloud Spanner, Anthos Config Management, and Stackdriver telemetry. Customers include large enterprises in sectors such as finance, healthcare, and telecommunications that require interoperability across platforms like IBM Cloud and Oracle Cloud Infrastructure. The platform competes with offerings from Red Hat OpenShift, VMware Tanzu, and Azure Arc.
Architecture and components
Anthos uses a control plane to manage clusters across heterogeneous infrastructure, leveraging Kubernetes clusters running on Google Kubernetes Engine in cloud regions, on-premises via VMware vSphere, or on bare metal. Key components include Anthos Config Management for policy-as-code, Anthos Service Mesh based on Istio and Envoy for observability and traffic routing, and Anthos GKE On-Prem for running GKE-compatible clusters in data centers. Additional integrations include Cloud Build for CI/CD, Artifact Registry for container images, and Cloud Identity for authentication and single sign-on with OAuth 2.0 and SAML providers such as Okta and Ping Identity. Anthos also supports hybrid networking through Cloud Interconnect, VPN, and software-defined solutions from Cisco and Juniper Networks.
Deployment and management
Administrators deploy Anthos clusters using tools and APIs compatible with Kubernetes declarative manifests, GitOps workflows, and continuous delivery pipelines modeled after practices from GitHub, GitLab, and Bitbucket. Anthos Config Management enables policy bundling via Git repositories stored in systems like Cloud Source Repositories or GitHub Enterprise, enforcing Role-Based Access Control with links to Cloud IAM and directory services such as Active Directory. Management features include centralized logging and monitoring through Stackdriver Monitoring and Stackdriver Logging, and lifecycle operations orchestrated with automation tools from Terraform, Ansible, and Puppet. For networking and service discovery, Anthos interoperates with technologies from Istio, Envoy, and Linkerd and supports ingress controllers used by NGINX and Traefik.
Security and compliance
Anthos incorporates security controls aligned with standards and frameworks such as ISO/IEC 27001, SOC 2, PCI DSS, and HIPAA to support regulated industries. It uses workload identity and service account isolation provided by Cloud IAM and Workload Identity for secure pod-to-service authentication, and integrates with key management solutions like Cloud KMS and third-party hardware security modules from Thales and HSM Consortium partners. Anthos Config Management enables admission controls, policy enforcement, and vulnerability scanning with tools from Google Cloud Security Command Center, Clair, and Aqua Security. Networking security is enhanced through mutual TLS provided by Istio and encryption in transit with protocols standardized by IETF bodies such as TLS.
Use cases and adoption
Enterprises adopt Anthos for workload modernization, hybrid migrations from legacy virtualization stacks such as VMware vSphere and OpenStack, and multi-cloud deployment strategies involving Google Cloud Platform and Amazon Web Services. Use cases include edge computing in telecommunications with vendors like Ericsson and Nokia, retail platforms integrating SAP backends, and financial services accelerating application delivery while meeting compliance mandates from FINRA and Basel Committee on Banking Supervision. Developers use Anthos to enable microservices architectures leveraging patterns described in literature by authors from O'Reilly Media and industry groups like the Cloud Native Computing Foundation.
History and development
Anthos was announced at Google Cloud Next '19 as part of Google's strategy to offer hybrid cloud solutions that build on prior investments in Google Kubernetes Engine and open-source collaboration with the Cloud Native Computing Foundation. Early development incorporated technologies from the Istio project and partnerships with VMware and CNCF members; subsequent releases expanded multi-cloud support to Amazon Web Services and Microsoft Azure and added on-premises capabilities through integrations with VMware vSphere and bare-metal distributions. Over time, product evolution included the introduction of Anthos Service Mesh from Istio, Anthos Config Management, and expanded enterprise features such as compliance reporting and third-party ecosystem integrations with vendors like Cisco, Palo Alto Networks, and HashiCorp.
