I audited 500 K8s pods. Java wastes ~48% RAM, Go ~18%
Kubernetes cost optimization - catch expensive resource changes before they merge - WozzHQ/wozz
I audited 500 K8s pods. Java wastes ~48% RAM, Go ~18% launched on December 13, 2025 with 36 votes, #481 of 11,628 launches that month and more than 90% of that year's launches.
In plain words
This project presents findings from auditing 500 Kubernetes pods, revealing significant RAM waste differences across programming languages. Java applications were found to consume approximately 48% excess RAM, while Go-based applications wasted around 18%. The analysis is intended for developers and DevOps engineers evaluating language choices for containerized environments where resource efficiency matters.

KernoDec 2025 · kerno.io · ▲132Hey HN! Anibal, Sean, Vlad, Maxi and Karim here we're the co-founders of Kerno (https://www.kerno.io/). We're building a zero-hassle tool to help developers monitor and troubleshoot their services in a way that makes sense. No complex rollouts, no custom infra, no tons of instrumentation, no sidecars… none of that! Just a minimum effort, out-of-the box, highly contextualized and interactive experience so you and your team can focus on shipping! We basically scan your cluster resources, build usable abstractions on top of all the kubernetes craziness, identify monitor your…

Run globally distributed full-stack apps on high-performance MicroVMs2023 · koyeb.com · ▲98Hi HN! We’re Yann, Edouard, and Bastien from Koyeb (https://www.koyeb.com/). We’re building a platform to let you deploy full-stack apps on high-performance hardware around the world, with zero configuration. We provide a “global serverless feeling”, without the hassle of re-writing all your apps or managing k8s complexity [1]. We built Scaleway, a cloud service provider where we designed ARM servers and provided them as cloud servers. During our time there, we saw customers struggle with the same issues while trying to deploy full-stack applications and APIs resiliently. As…
We built a managed Kubernetes provider at half the cost of AWS2023 · symbiosis.host · ▲25Since there’s a few discussions recently on $4 VPSes we thought you might be interested in Symbiosis, a cheaper and simpler managed k8s provider. Supported features include external LBs, encrypted+replicated storage and autoscaler. Infrastructure can be managed with UI, CLI, Terraform or Pulumi. Control planes are free of charge and a 1vCPU/2GB node goes for $6 per month. We’re live in Germany right now and we’re expanding into US during 2023. Feel free to try it out and leave a comment.
- KCK8s Cleaner – Roomba for Kubernetes2024 · sveltos.projectsveltos.io · ▲68
Hello HN community! I'm excited to share K8s Cleaner, a tool designed to help you clean up your Kubernetes clusters. As Kubernetes environments grow, they often accumulate unused resources, leading to confusion, waste, and clutter. K8s-cleaner simplifies the process of identifying and removing unnecessary components. The tool scans your Kubernetes clusters for unused or orphaned resources—including pods, services, ingresses, and secrets—and removes them safely. You can fully customize which resources to scan and delete, maintaining complete control over what stays and what goes. Getting…

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…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
