Seamlessly add a GraphQL API to your Istio-based service mesh or Envoy Proxy-based API Gateway

What is GraphQL?

GraphQL is a query language for your APIs with a server for fulfilling queries from your user interfaces. GraphQL provides a more powerful and flexible alternative to REST for pulling data from your microservices.

GraphQL enables declarative data fetching where a client specifies exactly what data it needs from an API and underlying services. Instead of multiple endpoints that return fixed data structures, a GraphQL server only exposes a single endpoint and responds with precisely the data a client requested.

The declarative model creates a consistent, predictable API. Even as your backend services and data sources change, the API doesn’t change from the client’s perspective.

Bringing GraphQL to Istio and Envoy Proxy

The Gloo GraphQL module embeds a GraphQL server natively into Gloo Mesh and Gloo Edge enabling federated GraphQL queries of your APIs using your service mesh and API gateways. No additional GraphQL servers required!

GraphQL meets Istio and Envoy

Combine the developer-friendly GraphQL query language for APIs with Istio’s ability to secure, manage, and observe application traffic across microservices. This eliminates the need for a distinct system of servers and schema libraries of parsers and resolvers for GraphQL; all of your policies and requests can be managed in Envoy Proxy filters. Leveraging the existing capabilities Solo.io provides via Envoy, you can scale from single, monolithic GraphQL APIs to a federated graph spanning multiple clusters.

GraphQL runs together to Envoy Proxy in Gloo Edge

No need to integrate with third-party libraries. If you have existing REST and gRPC APIs, we make it easier to build on a solid foundation. This is much simpler than tying into your own APIs which you will have to manage indefinitely.

Performance, Scalability & Reliability

Solo.io’s GraphQL extension leverages Envoy for its network performance and minimal footprint, and it scales independently of your services. Run GraphQL as federated filters in Envoy sidecars efficiently handling the queries, directing the data requests to the appropriate microservices, and coordinating responses. You can automatically leverage Gloo’s infrastructure for routing, rate limiting, load balancing, and global failover. Eliminating the additional network hop to a separate GraphQL server improves performance and avoids an extra failure mode on the data path.

Monitoring & Insights

Integrated monitoring provides access to key metrics for GraphQL requests, query execution and upstream resolvers to monitor performance and debug issues. Export metrics with Prometheus and Grafana.

Manage GraphQL lifecycle and collaborate across teams

Develop GraphQL with 100% GitOps-compatible declarative configurations. Leverage a friendly UI for app dev teams to boost productivity in GraphQL API development.

Security, Authentication and Authorization

GraphQL simplifies developer access to APIs, but what about the underlying authorization and authentication for data and services. Gloo Mesh and Gloo Edge offer comprehensive security capabilities, providing safe and granular role-based access to data. Integrated DLP and WAF provide a more secure infrastructure for GraphQL. Consistent policies across GraphQL, service mesh, and API gateways makes compliance easier. Single API end points and schemas also help lock down your apps.

CODELESS GRAPHQL API

Seamlessly deploy a federated GraphQL server and connect it to your APIs and data sources with a declarative configuration. No need to program separate API query management for your microservices, and your developers don’t need to know how microservices connect behind the scenes.

DECLARATIVE CONFIGURATION WITH FEDERATION AND RBAC

Declaratively define GraphQL schema and server capabilities, including role-based access control (RBAC) using familiar YAML. Advanced federation allows teams to operate independently while contributing to the overall graph.

ORCHESTRATION, DATA AGGREGATION, AND EXTENSIBILITY

Gloo Mesh and Gloo Edge will orchestrate your queries for scale, can gather responses across microservices. You can also write customer resolvers with Web Assembly (Wasm) to extend your API infrastructure to meet your specific needs.
