AWS API Gateway vs Gloo Edge: Managed Cloud vs Envoy K8s Gateway (2026)
By API7.ai Team
Last updated: June 2026
AWS API Gateway and Gloo Edge take fundamentally different approaches: a fully managed, serverless AWS service versus an open-source, Envoy-based Kubernetes gateway from Solo.io. This guide compares architecture, Kubernetes support, protocols, service mesh, security, observability, and pricing so you can pick the right fit.
AWS API Gateway is a fully managed, serverless gateway best when your stack is AWS-centric and you want zero infrastructure to run. Gloo Edge is an Envoy-based, Kubernetes-native gateway best when you run a Kubernetes-first architecture and need gRPC, Istio integration, or cluster portability. The decision comes down to managed-AWS simplicity versus Kubernetes/Envoy flexibility.
- Serverless APIs fully on AWS (Lambda, IAM): AWS API Gateway
- Kubernetes-first edge with Envoy and Istio: Gloo Edge
- Portability across clusters and clouds: Gloo Edge

What is AWS API Gateway?
AWS API Gateway is a fully managed, serverless service for REST, HTTP, and WebSocket APIs, integrated tightly with AWS Lambda, IAM, Cognito, and CloudWatch — with no servers to run.
AWS API Gateway is a fully managed, serverless API gateway for creating REST, HTTP, and WebSocket APIs. It scales automatically and integrates tightly with AWS Lambda, IAM, Cognito, and CloudWatch, with no servers to operate.
Architecture
Fully managed AWS service
License
Proprietary (usage-based)
Best for
Managed, serverless APIs on AWS
Pros
- Fully managed and serverless — no infrastructure to run
- Deep AWS integration (Lambda, IAM, Cognito, CloudWatch, X-Ray)
- Auto-scaling with a default 10,000 RPS account limit (adjustable)
- Native managed developer portal (Amazon API Gateway Portal, 2025)
Cons
- AWS-only; no multi-cloud, on-prem, or edge path
- Pay-per-request pricing scales up with traffic volume
- No native gRPC, TCP/UDP, or GraphQL passthrough
- High lock-in: API definitions and IAM policies are AWS-specific
What is Gloo Edge?
Gloo Edge (Gloo Gateway) is Solo.io’s open-source, Kubernetes-native API gateway built on Envoy, with a control plane that programs Envoy via xDS, CRD-based routing, and deep Istio integration.
Gloo Edge (also called Gloo Gateway) is Solo.io’s open-source, Kubernetes-native API gateway built on the Envoy proxy. Its control plane programs Envoy via xDS, with CRD-based routing, the Kubernetes Gateway API, and deep Istio integration.
Architecture
Envoy proxy + K8s control plane
License
Apache-2.0 core + Enterprise
Best for
Kubernetes-native Envoy/Istio gateway
Pros
- Envoy-based data plane: HTTP/2, gRPC, WebSocket
- Kubernetes-native: Gateway API, CRDs, service discovery
- Deep Istio service mesh integration
- Open-source core (Apache 2.0); Wasm and Envoy filters
Cons
- Kubernetes-first; less suited to non-K8s infrastructure
- GraphQL, WAF, ext-auth, and Gloo Portal are Enterprise-only
- Enterprise pricing is custom (no public price list)
- Envoy control plane adds operational moving parts
Architecture: managed service vs Envoy control plane
AWS API Gateway hides all infrastructure behind a managed AWS endpoint; Gloo Edge gives you an Envoy data plane and a Kubernetes control plane you run and configure with CRDs.
AWS API Gateway is fully managed: you define APIs in the Console, CLI, or CloudFormation/CDK, and AWS runs and scales the gateway for you. That removes operational burden and ties cleanly into Lambda, IAM, and CloudWatch, but the gateway lives only inside AWS and is configured the AWS way.
Gloo Edge is the decoupled control plane for Envoy: it watches Kubernetes resources and dynamically programs the Envoy data plane via the xDS APIs. You operate it inside your cluster with CRD-based routing and the Kubernetes Gateway API, which gives deep control and portability across clusters at the cost of running the Envoy control plane yourself.
Performance & pricing
AWS API Gateway is pay-per-request and auto-scales to a default 10,000 RPS account limit; Gloo Edge’s Envoy data plane is self-hosted, free as open source, with Enterprise custom-quoted. Model both against your own traffic.
AWS API Gateway scales automatically with a default account-level limit of 10,000 requests per second per Region (adjustable via Service Quotas; some Regions default to 2,500 RPS), with burst capacity governed by a token-bucket algorithm. Because it is a managed abstraction, the relevant cost lever is the per-request price: $3.50 per million REST API calls (tiered down at volume), $1.00 per million HTTP API calls, plus $0.09/GB data transfer — so spend grows with traffic.
Gloo Edge runs the Envoy data plane on infrastructure you provision, so throughput and latency depend on your cluster sizing rather than a per-request meter. The open-source edition is free under Apache 2.0; Gloo Edge Enterprise (WAF, GraphQL, ext-auth, Gloo Portal) is a custom Solo.io subscription with no public price list. Benchmark Envoy on your own hardware and model AWS per-request cost against your real volume rather than relying on headline numbers.
AWS API Gateway vs Gloo Edge: feature comparison
Across architecture, Kubernetes, protocols, service mesh, security, and pricing, the two trade managed-AWS simplicity against Kubernetes/Envoy flexibility.
