Key Differences

Core Philosophy

Anthos

Multi-cloud application management platform built on Kubernetes. Provides unified control plane for GKE clusters on Google Cloud, AWS (via Anthos on AWS), Azure (via Anthos on Azure), and on-premises (via Anthos on VMware or bare metal). Goal: consistent Kubernetes experience everywhere with Google Cloud-managed services.

Expanso

Built around 'Compute Over Data'-running jobs where data already exists rather than forcing data to move. When you're processing data in GCS buckets across regions, S3 buckets in AWS, Azure Blob Storage, and on-premises databases, Expanso eliminates the cost and complexity of centralizing data before processing it.

Vendor Lock-in & Flexibility

Anthos

While marketed as multi-cloud, Anthos creates dependency on Google Cloud control plane, Config Management, and Service Mesh. Requires Anthos licenses, GCP connectivity for management, and uses Google's opinionated approach to multi-cloud. Migrating away means replacing your entire orchestration layer.

Expanso

Truly cloud-agnostic. No requirement for any cloud provider's control plane. Run the same orchestration across GCP, AWS, Azure, on-premises, edge-without licensing fees tied to a specific vendor. When business needs change, your orchestration layer doesn't need to be re-architected.

Cost Model & Data Transfer

Anthos

Anthos licensing costs scale per vCPU (~$100/vCPU/month for on-premises, cloud pricing varies). While it manages multi-cloud workloads, it doesn't address data transfer costs between clouds or from edge to cloud. Moving data between GCP, AWS, and Azure to centralize processing still incurs massive egress fees.

Expanso

Process data where it lives-eliminating inter-cloud transfer costs. Run analytics on GCS data in GCP region, S3 data in AWS region, on-premises data locally-all orchestrated through a single control plane. Save the egress fees (often $0.08-0.12/GB) by moving computation (kilobytes) instead of data (petabytes).

Service Mesh & Application Complexity

Anthos

Includes Anthos Service Mesh (based on Istio) for traffic management, security, and observability. While powerful, service mesh adds significant complexity-additional sidecars, configuration, operational overhead. Many organizations struggle with service mesh complexity for workloads that don't need it.

Expanso

Focused on data-intensive batch and analytical workloads rather than microservice communication patterns. No service mesh overhead for jobs that process data and return results. Simpler operational model for use cases like ML training, data transformation, scientific computing, or batch analytics.

Edge & Disconnected Environments

Anthos

Anthos on bare metal supports edge deployments, but still requires periodic connectivity to Google Cloud for license validation, management, and updates. Disconnected operation is limited. Each edge location requires substantial resources to run a full Kubernetes cluster with Anthos components.

Expanso

Designed for intermittent connectivity and resource-constrained edge. Jobs execute during network outages, queue results locally, sync when possible. Single lightweight control plane orchestrates thousands of edge locations without each needing a full cluster. Perfect for retail stores, remote sites, mobile platforms, or offshore installations.

Collaboration, not Competition

Anthos and Expanso serve different architectural needs and can complement each other. Use Anthos to manage your containerized applications and microservices across hybrid and multi-cloud environments-its unified control plane and service mesh excel at application platform management. Then use Expanso to run data-intensive workloads across your distributed data landscape-processing GCS buckets in multiple GCP regions, analyzing S3 data in AWS, transforming Azure data lakes, and running edge analytics, all without centralizing data first.

Anthos is your choice for multi-cloud application platforms. Expanso is your choice when data locality, transfer cost elimination, and true cloud independence drive your architecture.
