There are books & many articles online, like this one arguing for using Postgres for everything. I thought I’d take a look at one use case - using Postgres instead of Redis for caching. I work with APIs quite a bit, so I’d build a super simple HTTP server that responds with data from that cache. I’d start from Redis as this is something I frequently encounter at work, switch it out to Postgres using unlogged tables and see if there’s a difference.https://dizzy.zone/2025/09/24/Redis-is-fast-Ill-cache-in-Postgres/

If you’ve been paying any attention at all to the cloud-native ecosystem, you’ve doubtless run across discussions about the merits - or lack thereof - of sidecars. In a lot of ways, this is kind of silly: sidecars are a fairly low-level implementation pattern, and it would probably make sense to see them considered an implementation detail rather than the latest hot marketing topic. In other ways, though, we live in an imperfect world and we often do have to pull back the curtains to take a look at the technology underneath the tools we use: understanding the tradeoffs made by our tool choices is often critical to getting the most out of those tools, and architectural decisions are always about tradeoffs. For various reasons, I ended up being the one to take on the job of pulling back the curtain on both Linkerd’s choice to use the sidecar pattern and Istio Ambient’s choice to avoid it, and look into the ramifications of those choices. I did this in the obvious way: I ran both meshes under load and measured things about them. It was simultaneously frustrating and fascinating, often in surprising ways.https://linkerd.io/2025/05/21/behind-the-great-sidecar-debate/index.html

Mantis is a next-generation Infrastructure as Code (IaC) tool that reimagines how we manage cloud and Kubernetes resources. Built as a fork of OpenTofu and powered by CUE, Mantis combines the best of Terraform and Helm while solving their limitations. To manage cloud resources, Mantis compiles CUE configurations into Terraform compatible json and leverages the Opentofu engine to orchestrate it. To manage K8s resources, Mantis compiles CUE configurations yaml manifests which can be deployed either using mantis or via integrations with Gitops tools like ArgoCD or FluxCDhttps://github.com/augur-ai/mantis
