Aperture – Unified Reliability Management for Microservices
Hello HN, We're excited to introduce Aperture[0], an open-source project that addresses the challenges of detecting and mitigating reliability and performance issues in microservices. Aperture provides a reliability abstraction layer, enabling globalized load control for easier management across distributed microservice architectures[1]. DoorDash uses Aperture and detailed its implementation in a recent blog post[2], discussing microservice architecture failures such as cascading failure, retry storm, death spiral, and metastable failure. The post also examines the limitations of existing…
Aperture – Unified Reliability Management for Microservices launched on March 16, 2023 with 45 votes, #1,666 of 5,007 launches that month and more than 90% of that year's launches.
In plain words
Aperture is an open-source reliability management platform for microservices that provides load control across distributed architectures. It detects and mitigates performance issues like cascading failures, retry storms, and death spirals through prioritized load shedding. Designed for teams managing complex microservice systems, Aperture offers a centralized abstraction layer to coordinate reliability measures that existing tools like circuit breakers and auto-scaling handle individually.

Aperture Open Source Flow Control and Reliability Platform2022 · github.com · ▲6Hello people of HN and fellow SREs! Over the past year, we have been building Aperture - an open-source flow control and reliability platform for cloud applications. Over the past few years, companies like LinkedIn[1], Google [2], Netflix [3], Stripe [4] have built cutting-edge flow control technologies to keep their applications reliable. Flow control is powerful because it enables graceful degradation- the ability to preserve key user experience pathways, even in the face of application failures. With Aperture project, we hope to democratize building reliable applications with effective…

Go Micro – A distributed systems development framework2020 · go-micro.dev · ▲115I can't tell if HN is the right kind of place for this stuff anymore since people are so advanced in their use but I thought it was interesting to leverage my existing Go microservices framework and turn it into the core of what would provide tools for an agent cli or whatever beyond that. Extensibility is key. Thought I'd share and get a conversation going.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
