Envoy Gateway Makes Using Envoy Proxy Easier for Developers and Reverses Fragmentation

Members of the steering group for Envoy Gateway (EG), including Envoy creator Matt Klein and representatives from Ambassador Labs, Fidelity Investments, Tetrate, and VMware, Inc., today announced their joint commitment to the project, which launched today at KubeCon + CloudNativeCon, Europe 2022, under the auspices of the Cloud Native Computing Foundation® (CNCF®). Envoy Gateway is a new effort within the Envoy proxy open source project to simplify Envoy use in cloud-native application development.

Envoy Gateway will reduce existing, redundant efforts around Envoy and make it much easier for application developers to use Envoy as a basic API gateway “out of the box” and as a Kubernetes Ingress controller. Exposing a simplified set of APIs, and implementing the Kubernetes Gateway API, EG makes it easier to extend Envoy. Developers will now have a cost-free, unfettered way to provide external access to their work in progress. At the same time, Envoy Gateway will not replace API management features currently found in commercial products.

“Envoy has achieved a great deal of success since we first released it in 2016,” said Matt Klein, founder of the Envoy proxy project. “And community has been at the heart of Envoy from the beginning. With the community-driven Envoy Gateway project, we see the opportunity to make Envoy accessible to many more users through the addition of simplified APIs and new capabilities explicitly targeted at north-south / edge proxy use cases.”

Envoy is already widely used for traffic between separate services in a microservices application—that is, east-west traffic. With Envoy Gateway, Envoy will also be easy to use for north-south traffic—traffic between an application and the outside world, as with consumers of an application’s APIs.

Envoy Gateway—Extensible Open Source Infrastructure for the Cloud-Native Future

IT organizations worldwide want to establish and use a rich, robust, modern stack of open source software for cloud-native application development and delivery, under the management of organizations such as the Linux Foundation and CNCF. Commercial offerings and projects within each IT team can then add value on top of this core infrastructure.

Envoy is fast becoming the go-to networking substrate within this modern, cloud-native stack. However, the need for API access, traffic routing, and other ingress capabilities has recently led to fragmentation in the Envoy ecosystem. Envoy Gateway will bring this needed functionality back into the main Envoy project and make it less confusing and time-consuming for developers to access Envoy.

Implementation Via Kubernetes Gateway API

Envoy Gateway will expose a version of the Kubernetes-native Gateway API, with Envoy-specific extensions. This is an expressive, extensible, role-oriented API well-suited to use by developers. Gateway API is either implemented, or in progress, for Istio, the Contour project (which originated at VMware), Emissary-ingress (which originated at Ambassador Labs), and others.

When users create Gateway API resources, they will be translated into native Envoy API calls, so Envoy and xDS, its native API, will not need to be changed to add this new support.

Advantages for Developers, Infrastructure Administrators and Business Decision-Makers

Application developers will experience the most positive impact from Envoy Gateway. They will be able to run Envoy Gateway and begin routing traffic to their applications. They will no longer need to build their own control plane, or extend an existing control plane such as a Go or Java control plane, or bring in a vendor solution at the early stages of their projects. They can just configure routes for the application and share them.

Infrastructure administrators will be able to easily offer an Envoy-native experience to application teams, without needing to adopt a vendor solution just to get basic gateway functionality. They will be able to manage instances of Envoy Gateway without interfering with developer access to them. Envoy Gateway will allow them to deliver consistent application networking capabilities across heterogeneous environments.

Executives and decision-makers will have Envoy as a standard and, we expect, widely-used solution for API access and Kubernetes ingress. They will also benefit from faster and easier development and delivery of more secure and robust software and services.

About Envoy

Originally created by Matt Klein and built at Lyft, Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and “universal data plane” designed for large microservice “service mesh” architectures. Built on the learnings of solutions such as NGINX, HAProxy, hardware load balancers, and cloud load balancers, Envoy runs alongside every application and abstracts the network by providing common features in a platform-agnostic manner. When all service traffic in an infrastructure flows via an Envoy mesh, it becomes easy to visualize problem areas via consistent observability, tune overall performance, and add substrate features in a single place.
