Managing Infrastructure as Code (IaC) at scale is fundamentally different from handling a handful of resources. While getting started with Terraform/OpenTofu is relatively straightforward, maintaining large-scale infrastructure deployments introduces challenges that can’t be solved by simply writing more code. Code organization becomes a critical factor in whether your infrastructure remains manageable or devolves into a maintenance nightmare.

AWS PrivateLink provides a secure method for sharing and accessing services across VPCs and accounts. It ensures that all traffic remains within the AWS network, avoiding exposure to the public internet. Before December 2024, both service providers and consumers were required to be in the same AWS Region. With the launch of native cross-region connectivity for AWS PrivateLink, you can now share and access VPC endpoint services across different Regions.

As time passes, OpenTofu and Terraform become more distant from each other. CanI.TF helps us to understand their differences quickly.

Simplify the management of Terraform modules in your monorepo with this GitHub Action, designed to automate module-specific versioning and releases. By streamlining the Terraform module release process, this action allows you to manage multiple modules in a single repository while still maintaining independence and flexibility. Additionally, it generates a beautifully crafted wiki for each module, complete with readme information, usage examples, Terraform-docs details, and a full changelog.

How we've redefined the PM and engineer relationship

🔎 Feluda is a Rust-based command-line tool that analyzes the dependencies of a project, notes down their licenses, and flags any permissions that restrict personal or commercial usage.

PGWATCH: PostgreSQL metrics monitor/dashboard

I don't know if you followed the release of the last generation of CPUs. AMD's latest Genoa CPU (AMD EPYC™ 9965) can run 768 threads. It has 192 cores per socket and 2 threads per core, with 2 sockets. Imagine adding 10 TB of RAM to such a beast! Of course, everyone will think of how useful it will be for virtualization. As a database person, I'd rather ask myself what Postgres could do with so many resources. I love simplicity in architecture. But I often meet customers with huge resource needs. With average hosts nowadays, the best answer for them is sometimes multi-parallel processing (MPP).

So, with this new hardware, can we stop using horizontal scalability? To understand the impact of running PostgreSQL on it, we must examine a few technical limits. The analysis will begin with NUMA (Non-Uniform Memory Access) architecture. Next, we will address I/O bandwidth limits. They are a big factor, no matter the CPU or memory. Next, we will look at how PostgreSQL behaves with many connections. This topic has historical limits that bring up key questions. Finally, we will test parallel queries. We will examine their scalability and effectiveness on systems with many CPU threads.

Nping is a Ping tool developed in Rust. It supports concurrent Ping for multiple addresses, visual chart display, real-time data updates, and other features.
