AWS RDS Blue/Green Deployment: Reduce Storage and Upgrade Your RDS Instance with Minimal Downtime
Managing Amazon RDS efficiently becomes challenging as applications evolve. Over time, databases often end up with over-allocated storage, outdated engine versions, or instance types that no longer match actual workloads. Unfortunately, Amazon RDS does not allow you to directly reduce allocated storage on an existing database instance. Traditional approaches to fix this usually involve creating […]
Eliminate Critical Kubernetes Storage Bottlenecks Using High-Performance S3 Mount Points
A Production-Hardened Deep Dive into goofys-based S3 Mounting, Infrastructure Trade-offs, and When to Use What This article dissects one of the most pragmatic solutions: mounting S3 buckets directly onto Kubernetes nodes using goofys, IAM roles, and DaemonSets, then exposing them to pods via hostPath volumes. The approach I’ll detail is production-tested across workloads ranging from […]
Upgrade EKS cluster: Top 10 Best Practices
Upgrading Amazon EKS clusters is one of the most critical operational tasks for Kubernetes administrators, requiring meticulous planning, comprehensive testing and careful execution. Unlike traditional infrastructure upgrades where a simple reboot might suffice, EKS cluster upgrades involve coordinating multiple components across the control plane and data plane while maintaining application availability and data consistency. This […]
Critical Promtail Deprecation: The Ultimate Guide to What’s Next for Log Collection in Grafana
With the deprecation of Promtail, teams using it to collect and push logs to Loki now need to plan their migration path. Promtail’s core functionality is being replaced by Grafana Alloy, a unified and modular observability agent that brings together logs, metrics and traces under one framework. While Promtail has been a cornerstone of Loki-based […]
Top 10 Amazon EKS Add-ons to Supercharge Your Cluster
Amazon EKS Add-ons are packaged Kubernetes operational software components that AWS can install and manage on your clusters. The EKS Community Add-ons are a set of AWS-validated open-source tools (currently metrics-server, kube-state-metrics, Prometheus node exporter, cert-manager and external-dns) that simplify cluster observability, security and operations. In addition, AWS and partners provide other important EKS add-ons […]
Argo CD vs Flux 10 Key Differences and How to Select the Best Fit
The shift to GitOps has changed the way we think about deploying and managing applications on Kubernetes. In the past, release engineers and DevOps teams spent countless hours on manual deployments, fighting config drift and writing long runbooks no one wanted to read. Today, with GitOps, we can treat Git as the source of truth […]

Which One To Choose NVIDIA Device Plugin or NVIDIA GPU Operator
When we talk about Kubernetes for machine learning and artificial intelligence or even high-performance computing tasks, one of the crucial components associated with it is GPU. As a matter of fact, Kubernetes does not come with built-in support for GPUs. To get the support for the same NVIDIA has come up with two kinds of […]
ECS vs. EKS: When to Choose ECS Over EKS
Managing security and compliance across multiple AWS accounts can be challenging, especially when each account represents a different product, environment, or team structure. While isolating environments (such as production, staging, and development) in separate accounts improves security by limiting lateral movement, it also creates operational complexity. This post explores how to centralize security using native […]
