Opinions & Tutorials

How we saved $1.5 million per year with Cloud Cost Management (7 minute read)

Datadog used Cloud Cost Management to centralize visibility of cloud expenses and collaborated between FinOps and engineering to identify storage inefficiencies. Implementing optimized S3 storage classes and lifecycle rules reduced costs, generating an estimated $1.5 million in annual savings while creating a system to discover future opportunities.
Migrate to Amazon EKS: Data plane cost modeling with Karpenter and KWOK (7 minute read)

Organizations can simulate Kubernetes migrations to Amazon EKS using Karpenter and KWOK to observe node provisioning, optimize costs, and estimate compute requirements without launching real EC2 instances. The process involves backing up the source cluster with Velero, creating a destination EKS cluster, deploying Karpenter with KWOK for virtual nodes, restoring workloads, and analyzing resource allocation for accurate cost modeling.

Top 30 Argo CD Anti-Patterns to Avoid When Adopting Gitops (20 minute read)

Argo CD adoption often begins smoothly, but developers can quickly get frustrated when common anti-patterns emerge. These pitfalls include misunderstanding declarative setups, misusing Gitops tools like Helm and Kustomize, poor application organization, cluster mismanagement, and overloading Argo CD beyond its intended scope.
Why Relying on LLMs for Code Can Be a Security Nightmare (2 minute read)

LLM-generated code often lacks security awareness.  LLMs often mimic insecure patterns found in online examples, scaling the risk of vulnerabilities in production code. Developers should keep humans in the loop for threat modeling, abuse cases, and defense design.
