With AWS, you choose and connect the infrastructure. With Arc Fusion, the deployment and API foundation arrive as a managed whole.
Identity, data, files, events, and business workflows are available when your Arc deployment is provisioned. Give your team and AI agents more room to build the product, connect enterprise systems, and create customer value.
Connected identity, permissions, data, sync, and business APIs. Capacity and integration scope agreed for your workload.

Identity, users, permissions, data, sync, and business workflows share one API foundation and managed deployment.

Approximate budgets for a roughly comparable service stack. Capacity, region, traffic, and architecture affect the final bill. Initial API development and integration, payment processing, and AI model usage are additional.
A production cluster from Tier 1. The base scope includes application compute, a resilient database cluster with recovery capacity, streaming and queues, load balancing, DNS, security controls, monitoring, backups, object storage, and CDN delivery in one region. Tier 2 increases compute, data, and traffic headroom. Tier 3 adds a larger footprint and a second-region budget allowance.
AWS uses Aurora writer and reader/failover capacity with replicated storage, a three-broker provisioned MSK cluster, SNS/SQS, and the surrounding network and delivery services.
These tiers compare similar service responsibilities; they are not Arc hardware specifications or throughput commitments. Costs use a 730-hour month and on-demand-style capacity budgets. Usage, recovery targets, cross-region replication, and discounts change the result. US East (N. Virginia) cost baseline.
Open source still needs runtime. The Keycloak selection adds dedicated application-node capacity; its database, routing, and baseline monitoring use the infrastructure already budgeted. No Keycloak license or per-connection fee is added. Maintenance is optional below the service choices. WorkOS uses its free basic user-management tier up to 1M monthly active users; SSO and directory sync add separate connection fees only when selected. Another provider uses the fee you enter. Only one identity-provider option is counted.
The application layer matters, too. A cloud account and an identity service still need to be connected to your product’s permissions, data model, content, subscriptions, agreements, invoices, and transaction workflows. Building and integrating that API layer is outside this monthly services estimate. Arc Fusion supplies the connected API suite with its managed deployment; confirm required integrations and scope with our team.
Category ranges are Arc estimates informed by the linked vendor pricing and architecture references, rather than vendor quotes. Sync-worker ranges are additional runtime budgets; they do not include initial connector development.
| Responsibility | Arc Fusion | DIY path |
|---|---|---|
| Application service APIs | Connected suite included | Build or integrate each capability |
| Deployment isolation | Customer-isolated deployment | Design and enforce the boundaries |
| Compute, data, storage & messaging | Configured as a managed foundation | Provision, connect, secure, and operate |
| Capacity and regions | Resize or expand the agreed deployment | Plan topology, changes, and validation |
| Service replacement | Integrate and replace through planned boundaries | Own all integrations and migration work |
Arc Fusion brings the services together so your team can focus on the product. You can integrate external providers and replace components as your requirements change.
Use your existing identity, data, or application services where they make sense.
Put integration boundaries around the capabilities you may want to replace later.
APIs and data mappings help scope a migration. Move components in stages, with integration work and validation planned for each provider.
