Amazon EBS on EKS: From PVCs to Persistent Storage

Image
Amazon EBS on EKS: From PVCs to Persistent Storage Running stateful apps on Kubernetes means you need storage that sticks around — even when pods restart or reschedule. That’s exactly where Amazon EBS on EKS comes in, giving your workloads reliable, block-level storage that Kubernetes can manage dynamically. This guide is for DevOps engineers, platform teams, and Kubernetes practitioners who are wiring up production-grade storage on AWS and want to get it right the first time. Here’s what we’ll walk through: Setting up the EBS CSI driver so Kubernetes can actually talk to Amazon EBS and handle dynamic provisioning Designing storage classes and managing Persistent Volume Claims on EKS so your apps get the right storage, sized and configured correctly Protecting your EBS data with backup and recovery strategies built for Kubernetes environments No fluff — just the practical stuff you need to get EKS persistent volume management working cleanly in real work...

AWS Cost Optimization Dashboard: How to Detect Idle Resources and Reduce Cloud Spending

Image
Stop Paying for AWS Resources You’re Not Using Cloud bills have a way of quietly growing while no one’s watching. One month you’re running a lean setup, and three months later you’re staring at charges for EC2 instances that haven’t served traffic in weeks, S3 buckets holding forgotten data, and load balancers attached to nothing. Sound familiar? This guide is for DevOps engineers, cloud architects, and finance-aware engineering leads who want to take back control of their AWS spending — without guessing where the money is going. Here’s what we’ll walk through together: What makes a solid AWS cost optimization dashboard — the specific metrics worth tracking versus the noise you can ignore How idle resource detection actually works in AWS — so you can spot unused resources before they silently drain your budget month after month Real strategies to reduce AWS spending after you’ve found the problem — not generic advice, but actio...

How to Build an AI Product Matching System Using Amazon Bedrock and S3 Vectors

Image
Build a Smarter Product Matching System with Amazon Bedrock and S3 Vectors If you’ve ever searched for a product online and gotten results that had nothing to do with what you wanted, you already know why AI product matching systems matter. Rule-based search breaks down fast when customers use natural language, misspell things, or search by concept rather than exact keywords. That’s the problem this guide helps you solve. This tutorial is for backend developers, ML engineers, and AWS practitioners who want to build a semantic product search pipeline that actually understands what users are looking for, not just what they typed. Here’s what we’ll walk through together: How Amazon Bedrock embeddings work and why they’re a practical starting point for generating vector representations of your product catalog How S3 Vectors indexing stores and organizes those embeddings so you can run fast, scalable similarity searches without managing a separate vecto...

AWS VPC Networking: Build a Secure Two-Tier Architecture with SSH ProxyJump

Image
Build a Secure AWS VPC Two-Tier Architecture with SSH ProxyJump If you’ve ever spun up an EC2 instance and just… left port 22 open to the world, you’re not alone — but there’s a better way. This AWS VPC networking tutorial is for cloud engineers, DevOps practitioners, and developers who want to stop cutting corners on network security and start building infrastructure that can actually survive a production environment. Here’s what we’ll walk through together: How a two-tier architecture works and why splitting your resources into public and private subnets dramatically reduces your attack surface Setting up a secure VPC from scratch , launching EC2 instances in the right tiers, and locking down your AWS security groups so nothing gets in that shouldn’t Configuring SSH ProxyJump to reach your private subnet EC2 instances cleanly through a bastion host — no messy workarounds, no storing keys on jump servers By the end, you’ll have...

AWS Well-Architected Framework in Action: A Practical Guide to the 6 Pillars

Image
Stop Guessing. Start Building Cloud Architecture That Actually Works. If you’ve ever pushed a workload to AWS and wondered “did I do that right?”—this guide is for you. The AWS Well-Architected Framework gives cloud architects, DevOps engineers, and engineering teams a clear, proven way to evaluate and improve their cloud setups. Whether you’re building from scratch or auditing something that’s already live, the AWS 6 pillars —Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability—act as your north star. Here’s what we’ll walk through together: What the framework actually is and why it matters more than most teams realize Each of the six pillars broken down into plain-English takeaways you can act on today—covering everything from the AWS security pillar to AWS cost optimization How to run a real review using the AWS Well-Architected Tool so you’re not just reading theory,...

Terraform S3 Backend Explained: How to Manage Remote State Without DynamoDB

Image
Stop Overcomplicating Terraform State Management Most Terraform tutorials assume you need DynamoDB for state locking — but that’s not always true, and it’s definitely not the only way to manage Terraform remote state on S3. If you’re a developer or DevOps engineer who’s tired of spinning up extra AWS resources just to get a working backend, this guide is for you. We’ll walk through exactly how the Terraform S3 backend works, how to set it up without DynamoDB, and what your real options are for state locking when you want to keep things simple. Here’s what we’ll cover: How Terraform remote state actually works and why storing state locally is a bad idea the moment more than one person touches your infrastructure The step-by-step S3 backend setup — the backend configuration, the right S3 bucket settings, and what you actually need versus what’s just nice to have State locking alternatives and security basics — because skipping Dyn...
