Crossplane in the Trenches: Deletion Pitfalls and How to Prevent Them

Posted on August 12, 2025 by Dilyan Kostov

There’s an infrastructure-as-code tool that offers dynamic infrastructure and continuous reconciliation - it’s called Crossplane . If you’re using Crossplane right now, you should know about its deletion policies. Improper deletion handling can lead to orphaned cloud assets that continue accruing costs, and invisibly consume cloud quotas.

mise vs. nix-shell

Posted on May 9, 2025 by CECG Engineering

A Deep Dive into Modern Development Environment Tools In today’s fast-paced development world, having reliable tools to manage development environments is crucial. Two prominent solutions that have gained significant traction are mise (formerly rtx) and nix-shell . Whilst nix is a complex project in its own right we are just going to be exploring the nix-shell elements, steering clear of flakes and nixos for now. While both aim to solve the challenge of reproducible development environments, they take fundamentally different approaches. This article explores their philosophies, capabilities, and practical applications to help you understand what the hell is going on.

Leveraging ArgoCD in Multi-tenanted Platforms

Posted on April 9, 2025 by Derek Mortimer

ArgoCD is a popular Kubernetes-based declarative deployment tool, and for good reason! It has a polished Web and CLI-based UI, both supported by a general ArgoCD API and a flexible RBAC model. It’s designed to get you going quickly, leveraging familiar tooling such as Helm or Kustomize to manage the Kubernetes manifests you deploy to your clusters.

semver-utils: Streamlined semantic versioning from pipelines

Posted on March 30, 2025 by Derek Mortimer

At CECG , a recurring task we run into is the management of semantic version tags in Git repositories from automated pipelines. It’s straightforward in principle — just follow the Semantic Versioning rules! But in practice, we often saw a range of implementations with varying degrees of testing. To address this task in a repeatable and reusable manner, we built semver-utils , which we’re releasing under open-source now.

Multi-Node LLM Serving Using sig LWS and vLLM

This article provides a guide on how to serve large language models on multiple nodes running on Kubernetes. Challenges Large Language Model (LLM) serving is a challenging task. Namely:

Deploying Local LLMs for Sentiment Analysis in Platform Engineering

Posted on March 19, 2025 by Senna Semakula

Introduction Sentiment analysis is widely used in support and incident management, often relying on cloud-based AI services from OpenAI, AWS, or Google. However, self-hosting LLMs is becoming an attractive option for platform teams looking to reduce costs, keep data on-premises, and gain more control over model behaviour.

Exploring AIOps

Posted on March 19, 2025 by CECG Engineering

Our client’s exploration into AIOps, leveraging Grafana Cloud, marks an exciting new approach to IT operations management. This deeper dive into our journey with AIOps aims to demystify the process, share our learnings, and outline the concrete steps we’ve taken towards a more intelligent IT system.

Comparison: Kubeadmiral and Karmada

Posted on March 17, 2025 by Derek Mortimer

Kubeadmiral, Karmada, and Multi-cluster Federation Standards A client recently asked us for a comparison of two multi-cluster Kubernetes management technologies, specifically Kubeadmiral and Karmada . In this post we’ll introduce these technologies, and the Kubernetes standards that influenced their architecture, to enable multi-cluster workload orchestration. The focus will be entirely on managing the manifests inside existing Kubernetes clusters, specifically excluding discussion of standards such as the Cluster API which are concerned with the provisioning of new clusters from scratch.

Evaluating Large Scale Solutions for Multi Tenant Metrics System

Posted on November 4, 2024 by Korhan Ozturk

In our work with a client, we encountered a challenge with their multi-tenant Kubernetes platform. The platform was designed to provide a flexible environment where each tenant could independently manage their own services and infrastructure. As part of this setup, tenants were encouraged to create and maintain their own monitoring stacks using Prometheus and Alertmanager .

Supporting private service access in GCP from a multi-tenanted kubernetes platform
