Technical Debt for Middle Mile Broadband: Why Access-Agnostic Intelligent Middle Mile Matters

Technical debt refers to the future costs and limitations incurred when organizations opt for short-term solutions over robust, long-term scalable architectures. For the middle mile, technical debt often manifests as equipment or network designs that restrict long-term flexibility, scalability, or interoperability.

Why 2025 Changed Everything for DevOps and What Puppet Built to Meet It

In 2025, DevOps teams faced a pivotal moment. The era of treating security as an afterthought was over. Practically overnight, airtight protection became a non-negotiable requirement across every layer of the technology stack, whether on prem, in the cloud, or at the network’s edge. For many teams, this wasn’t just a technical hurdle; it was a daily source of stress.

How Kubernetes Node Affinity Works (And Why It Matters for K8s Cost Control)

Think about how airlines assign seats on a plane. Some have extra legroom. Some sit near exits. Some are cheaper, while others cost a premium. Certain passengers also have strict requirements, like families traveling together or travelers who paid for a specific class. Now imagine boarding everyone randomly. A passenger who paid for extra legroom (perhaps for health reasons) ends up squeezed into a middle seat. Families scatter across the cabin. Premium seats sit half empty while the back rows overflow.

Chaos Engineering Training: Zonal, Regional Failures and SSL/TLS Certificates Expiration

Learn how to test your system's resilience against critical infrastructure failures. This tutorial demonstrates how to simulate zonal and regional outages to validate your high availability setup, plus how to test SSL/TLS certificate expiration scenarios. Essential for ensuring your applications can handle real-world failure conditions and maintain uptime during certificate-related issues.

Chaos Engineering Training: Chaos Hub, Experiment Templates, Import as Local Copy and Reference

Learn how to leverage Chaos Hub in Harness Chaos Engineering to accelerate your resilience testing. This tutorial covers browsing the Chaos Hub for pre-built experiments, understanding experiment templates, and two key workflows: importing experiments as local copies for customization or referencing them directly from the hub. Perfect for teams looking to quickly implement chaos experiments without building from scratch.

Multi-environment DNS automation on Cloudflare using CircleCI and Terraform

Manually configuring DNS records for staging and production environments is a common pain point for developers and DevOps teams. As your organization grows and you manage more applications across different services, keeping DNS records up-to-date and error-free becomes increasingly challenging and time-consuming. Mistakes in DNS setup can lead to downtime, broken environments, or confusing deployments, especially when juggling multiple teams or microservices.
