Envoy is a high-performance Layer 7 proxy used to standardize traffic management, security, and observability for microservices and API gateways. It is commonly adopted by platform and DevOps teams running Kubernetes or hybrid environments that need consistent routing behavior and policy enforcement across many services. Envoy helps reduce operational drift by providing a uniform data plane for ingress, egress, and service-to-service communication.
It is typically deployed as a sidecar, gateway, or edge proxy and configured through declarative policies, making it a common foundation for service meshes and modern gateway architectures.
Networking, in the context of computer science and information technology, refers to the practice of connecting computers, servers, mainframes, network devices, peripherals, or other devices to exchange data and share resources. It encompasses both the physical (hardware) and logical (software) aspects of connections between devices. The primary goal of networking is to enable the sharing of data and resources, thereby improving efficiency and accessibility within and across computing environments. Networks can vary in size, ranging from simple local area networks (LANs) connecting a few devices in a single office, to complex wide area networks (WANs) spanning multiple geographic locations around the globe. Networking technologies and protocols facilitate communication and data transfer across these connections, adhering to standardized rules to ensure reliable and secure information exchange.
Envoy is a high-performance Layer 7 proxy used as a common data plane for service meshes and modern ingress/egress gateways. It is adopted to standardize traffic management, security controls, and observability across microservices without pushing these concerns into application code.
Envoy is commonly deployed as a sidecar proxy in a service mesh, as a standalone edge proxy, or embedded within gateway products. The main trade-off is operational complexity, since large fleets require disciplined configuration management, validation, and rollout automation to avoid configuration drift and hard-to-debug traffic behavior.
Common alternatives include NGINX, HAProxy, Traefik, and Caddy. For service mesh use cases, Envoy is frequently used under the hood by Istio, while Linkerd uses a different data plane approach.
More details on Envoy’s APIs and operational model are available in the official Envoy documentation.
Our experience with Envoy helped us build repeatable configuration patterns, validation workflows, and operational runbooks that we reuse to help clients standardize L7 traffic management, security controls, and observability across gateways and service-to-service communication.
Some of the things we did include:
This experience helped us accumulate significant knowledge across multiple Envoy use-cases—from edge routing and API gateway standardization to service mesh data plane operations—and it enables us to deliver high-quality Envoy setups that are maintainable, observable, and safe to operate at scale. For deeper reference on core concepts and configuration, we often point teams to envoyproxy.io.
