Remote IP Address with Go
We need remote ips Yesterday I was tasked with figuring out how to properly ascertain remote web client IP Addresses in our golang web services. This sounds like a stupidly easy exercise, and golang MUST have a fancy utility for this right? Nope. Turns out getting the remote IP Address is really hard. The naïve approach Within the golang net.Request structure there is a RemoteAddr attribute, which
How we built Pingora, the proxy that connects Cloudflare to the Internet
How we built Pingora, the proxy that connects Cloudflare to the Internet09/14/2022 This post is also available in 简体中文 and 繁體中文. IntroductionToday we are excited to talk about Pingora, a new HTTP proxy we’ve built in-house using Rust that serves over 1 trillion requests a day, boosts our performance, and enables many new features for Cloudflare customers, all while requiring only a third of the CP
Cloudflare、NGINXに代えて自社開発のRust製HTTPプロキシ「Pingora」をグローバルCDNに採用。性能向上しつつCPUとメモリ消費を3分の1に
Cloudflare、NGINXに代えて自社開発のRust製HTTPプロキシ「Pingora」をグローバルCDNに採用。性能向上しつつCPUとメモリ消費を3分の1に CDNプロバイダのCloudflareは、同社のグローバルなCDNの基盤として長らく利用してきたNGINXに代えて、同社自身がRust製のHTTPプロキシである「Pingora」を開発し利用していることを明らかにしました。 Pingoraはすでに同社のCDNに採用され、毎日1兆回以上のリクエストを処理し、性能向上や数多くの新機能の提供を実現しつつ、従来と比較してCPUとメモリリソースの消費はいずれも3分の1程度に収まっているとのこと。 Pingoraは現時点でコードなどは公開されていませんが、いずれオープンソース化の計画についても明らかにするとCloudflareは説明しています。 Today we are excited t
Kubernetes NodePort vs LoadBalancer vs Ingress? When should I use what?
Recently, someone asked me what the difference between NodePorts, LoadBalancers, and Ingress were. They are all different ways to get external traffic into your cluster, and they all do it in different ways. Let’s take a look at how each of them work, and when you would use each. Note: Everything here applies to Google Kubernetes Engine. If you are running on another cloud, on prem, with minikube,
Benchmarking low-level I/O: C, C++, Rust, Golang, Java, Python
This post is a continuation of Measuring network service performance. When my computer doesn’t have an Internet connection, I find that there is not much I can do with it. Indeed, we mostly use our laptops and smartphones to access information stored or generated somewhere else. It’s even hard to imagine the utility of non-user facing apps without network communication. While the proportion of I/O
GitHub - DeNA/PacketProxy: A local proxy written in Java
Full-featured local proxy tool Save all captured packets (i.e., requests and responses) and show them in the history tab Filter/Search packets in the history tab (e.g. requests==/api/v1/users to show only requests whose path contains /api/v1/users ) Modify the contents of intercepted packets before forwarding them to the destination Resend (or replay) captured packets with or without manually modi
Envoy proxy - home
Envoy is an open source edge and service proxy, designed for cloud-native applications As on the ground microservice practitioners quickly realize, the majority of operational problems that arise when moving to a distributed architecture are ultimately grounded in two areas: networking and observability. It is simply an orders of magnitude larger problem to network and debug a set of intertwined d
mitmproxy - an interactive HTTPS proxy
Command Line mitmproxy is your swiss-army knife for debugging, testing, privacy measurements, and penetration testing. It can be used to intercept, inspect, modify and replay web traffic such as HTTP/1, HTTP/2, WebSockets, or any other SSL/TLS-protected protocols. You can prettify and decode a variety of message types ranging from HTML to Protobuf, intercept specific messages on-the-fly, modify th
A python proxy in less than 100 lines of code
Ricardo Pascal Good-ish at writing code, but where I really shine is removing it. Denmark Github Twitter voorloop@gmail.com ##What is a tcp proxy?## It's a intermediary server intended to act in name of a client, and sometimes to do something useful with the data before it reaches the original target. Let's see a picture: My idea was to produce a proxy using only the default python library, and to
