forward-proxy VS pipy

Agreed. I am not at all against people learning how to do it. But if that's the purpose then it's probably better to present it as such (like the resources at your link does). But the claim that all you need is 100 LOC to make a proxy server work is a bit bogus when you rely on Ruby's standard library. Look at the code at https://github.com/jamesmoriarty/forward-proxy/blob/main/lib.... As expected, it doesn't parse headers but uses stdlib's code to do that. Good, less likely to have bugs. But that means that you can claim that you implemented an HTTP header parser in one line of code:

  req_headers = Hash[req.header.map { |k, v| [k, v.first] }]

Pipy is an open-source, lightweight, high-performance, modular, programmable, cloud-native network stream processor that is ideal for a variety of use cases ranging from (but not limited to) edge routers, load balancers & proxy solutions, API gateways, static HTTP servers, service mesh sidecars, and other applications. Previously we have covered several use cases, and in this blog post will continue our learning of Pipy by implementing an HTTP Tunnel functionality by only using the PipyJS scripting language.

But as the complexity of your apps and architecture grows, you might require more fine–grain control over your services. And if your organization requires Zero Trust and has a need for end–to–end encryption like mTLS, you should consider a service mesh like osm-edge a light weight, ultra fast, low resources, highly extensible, Service Mesh Interface (SMI) compatible, built for edge and cloud computing service mesh. When you have communication between services (east–west traffic), a service mesh allows you to control traffic at that level.

Below we list the most remarkable changes in the Core API and PipyJS. For a detailed change log, refer to Pipy Release Page

Flomesh Service Mesh(FSM) from Flomesh is Kubernetes North-South traffic manager, provides Ingress controllers, Gateway API, Load Balancer, and cross-cluster service registration and service discovery. FSM uses Pipy - a programmable network proxy, as its data plane and is suitable for cloud, edge, and IoT.

FSM is another open-source product from Flomesh for Kubernetes north-south traffic, gateway api contoller, and multi-cluster management. FSM uses Pipy, a programmable proxy at its core, and provides an Ingress controller, Gateway API controller, load balancer, cross-cluster service registration discovery, and more.

osm-edge is built on top of Open Service Mesh (OSM) v1.1.0 codebase and is a lightweight service mesh for resource-sensitive cloud environments and edge computing scenarios. It uses osm as the control plane and Pipy as the data plane and features high performance, low resources, simplicity, ease of use, scalability, and compatibility (x86/arm64 support).

We're very happy to announce the release of osm-edge 1.1. This release is the culmination of months of effort from the flomesh.io team and we are very excited to unveil it today. osm-edge is built on top of Open Service Mesh v1.1.0 codebase and is built purposely for edge computing and uses lightweight, high-performant, cloud native, and programmable proxy Pipy as its data plane and sidecar proxy.
