What is Google Service Directory Platform
Google Cloud Service Directory is a managed service registry for publishing, discovering, and connecting to services across Google Cloud environments. It targets platform teams and developers who need a centralized catalog of service endpoints and metadata for microservices running on VMs, containers, and managed platforms. The product integrates with Google Cloud networking and IAM to control who can register and resolve services, and it supports metadata-based lookup to help route clients to the right service instance.
Managed service registry on GCP
Service Directory provides a hosted registry so teams do not need to operate their own discovery backend. It supports registering services and endpoints with associated metadata, enabling consistent discovery patterns across projects and environments in Google Cloud. This reduces operational work compared with self-managed registries that require cluster-level maintenance and upgrades.
IAM-based access control
The service uses Google Cloud IAM to control who can create, update, and resolve service entries. This aligns service discovery permissions with existing cloud identity and policy management practices. It also supports separation of duties across teams by scoping access at project and resource levels.
Integrates with Google networking
Service Directory is designed to work with Google Cloud networking constructs and service-to-service connectivity patterns. It can be used alongside load balancing and service mesh approaches by providing a source of truth for service metadata and endpoints. This helps standardize discovery across heterogeneous runtimes (VMs and containers) within the same cloud environment.
Primarily Google Cloud scoped
Service Directory is a Google Cloud product and is most straightforward when services run on, or are connected to, Google Cloud. Multi-cloud or on-prem-first environments may need additional integration work to keep registrations and endpoint data consistent. Organizations seeking a single discovery plane across multiple clouds may find the operational model less portable than vendor-neutral alternatives.
Not a full service mesh
Service Directory focuses on registration and discovery rather than providing traffic management features such as retries, mTLS enforcement, or advanced routing by itself. Teams typically pair it with other components for load balancing, policy enforcement, and observability. This can increase architectural complexity when compared with platforms that bundle discovery with runtime traffic controls.
Limited containerization functionality
Despite being used in container-based architectures, Service Directory is not a containerization product and does not provide container build, runtime, or orchestration capabilities. Container lifecycle management still requires separate tooling for images, runtimes, and cluster orchestration. Buyers evaluating it under a containerization category should treat it as an adjacent capability rather than a replacement.
Plan & Pricing
Pricing model: Pay-as-you-go Free tier/trial: Google Cloud Free Trial (90-day $300 credit) and certain automatic integrations are priced at $0.00 (see Example costs). Note: Cloud DNS (Service Directory zones) is billed separately per Cloud DNS pricing. Example costs:
- Service Directory namespace, service, or endpoint (registered via API): $0.10 per namespace/service/endpoint per month (hourly equivalent shown on site: $0.000136986 per hour).
- Service Directory namespace, service, or endpoint (registered via automatic integration such as internal load balancer, Private Service Connect, or GKE): $0.00 per namespace/service/endpoint per month.
- Service Directory API calls: $1.00 per 1,000,000 Service Directory API calls per month.
- Hourly pricing (as provided on the official page): $0.000136986 per resource-hour for API-registered namespace/service/endpoint; $0.00 per resource-hour for automatic integration registrations; $1.00 per 1,000,000 API calls. Notes & limits:
- If you use Service Directory zones, Cloud DNS is billed separately.
- Private Service Connect / load-balancer integrations may incur additional load-balancing or data transfer charges (see Google Cloud docs).
- Google Cloud recommends contacting sales for custom quotes; pay-as-you-go billing applies. Discount options:
- No product-specific subscription tiers listed; Google Cloud provides standard enterprise sales/commitment and volume discount options (contact sales) and multi-product committed use discounts where applicable.
