An Envoy-Powered API Gateway

Important update

Important Gloo Edge was renamed to Gloo Gateway to align with Solo's support for the Kubernetes Gateway API. The existing Gloo Edge v1 APIs were not changed and continue to be fully supported. To find out more about the new Gloo Gateway v2 API that is based on the Kubernetes Gateway API, see the v2.0.x branch.

About Gloo Gateway

Gloo Gateway is a powerful Kubernetes-native ingress controller and API gateway. It excels in function-level routing, supports legacy apps, microservices and serverless, offers robust discovery capabilities, integrates seamlessly with open-source projects, and is designed to support hybrid applications with various technologies, architectures, protocols, and clouds.

Summary

• Using Gloo Gateway
• What makes Gloo Gateway unique

Using Gloo Gateway

• Kubernetes ingress controller : Gloo Gateway can function as a feature-rich ingress controller, built on top of the Envoy Proxy.
• Next-generation API gateway : Gloo Gateway provides a long list of API gateway features including rate limiting, circuit breaking, retries, caching, transformation, service-mesh integration, security, external authentication and authorization.
• Hybrid apps : Gloo Gateway creates applications that route to backends implemented as microservices, serverless functions and legacy apps. This feature can help users to -
  • A) Gradually migrate from their legacy code to microservices and serverless.
  • B) Add new functionalities using cloud-native technologies while maintaining their legacy codebase.
  • C) Allow different teams in an organization choose different architectures. See here for more on the Hybrid App paradigm.

What makes Gloo Gateway unique

• Function-level routing allows integration of legacy applications, microservices and serverless : Gloo Gateway can route requests directly to functions. Request to Function can be a serverless function call (e.g. Lambda, Google Cloud Function, OpenFaaS Function, etc.), an API call on a microservice or a legacy service (e.g. a REST API call, OpenAPI operation, XML/SOAP request etc.), or publishing to a message queue (e.g. NATS, AMQP, etc.). This unique ability is what makes Gloo Gateway the only API gateway that supports hybrid apps as well as the only one that does not tie the user to a specific paradigm.
• Gloo Gateway incorporates vetted open-source projects to provide broad functionality : Gloo Gateway support high-quality features by integrating with top open-source projects, including gRPC, GraphQL, OpenTracing, NATS and more. Gloo Gateway's architecture allows rapid integration of future popular open-source projects as they emerge.
• Full automated discovery lets users move fast : Upon launch, Gloo Gateway creates a catalog of all available destinations and continuously maintains it up to date. This takes the responsibility for 'bookkeeping' away from the developers and guarantees that new feature become available as soon as they are ready. Gloo Gateway discovers across IaaS, PaaS and FaaS providers as well as Swagger, gRPC, and GraphQL.
• Gloo Gateway integrates intimately with the user's environment : with Gloo Gateway, users are free to choose their favorite tools for scheduling (such as K8s, Nomad, OpenShift, etc), persistence (K8s, Consul, etcd, etc) and security (K8s, Vault).

Thanks

Gloo Gateway would not be possible without the valuable open-source work of projects in the community. We would like to extend a special thank-you to Envoy.
