Seeing Inside Amazon EKS with OpenTelemetry 🔍

Sat, 20 Jun 2026 07:45:10 +0530

Why This Setup?

Before getting into the architecture, a few quick notes. Telemetry goes to both New Relic and Honeycomb to test OpenTelemetry’s backend-independence promise and compare the two. New Relic wins on day-to-day usability — dashboards, APM, and alerts work intuitively. Honeycomb takes more getting used to, but its MCP server is where it genuinely shines: connected to Claude, you can ask plain-English questions against live telemetry — no NRQL or PromQL required. That’s the part worth jumping to 👇 first if you’re short on time.

Beyond Objects — Using Amazon S3 Files as a Native File System on EC2

Wed, 22 Apr 2026 12:30:10 +0530

Introduction

For over a decade, we’ve been known S3 is not a file system. We used hacks like s3fs-fuse or accepted the limited semantics of Mountpoint for S3. That has changed on April 2026.

GitLab Setup Unlocked: Your 10-Minute Fast-Track Guide

Sun, 12 Apr 2026 10:45:10 +0530

Setup Host

First, set up an instance. I chose AWS EC2, but you can use any cloud provider or your own physical server.

Hardware Requirements

Do not try to use the “Free Tier” t2.micro or t3.micro. GitLab runs several background services (PostgreSQL, Redis, Sidekiq) that require significant memory.

Terraform Modules - Simplify, Organise and Reuse Your IAC

Sun, 22 Dec 2024 19:26:10 +0530

A Terraform module is a container/template for multiple resources that are used together. Modules are a way to organize and reuse code in Terraform, making infrastructure management more efficient and maintainable.

We first define the resource templates, and then we call the templates from outside of the module structures and we can even modify them as per our needs.

Automate AWS VPC Setup with Terraform

Fri, 20 Sep 2024 19:26:10 +0530

Introduction

The VPC is a logical private network that allows us to control how our resources, like servers, are connected and protected.

With the help of VPC, we decide the range of IP addresses for the network, how we can divide the network into smaller parts, data flow into & out and rules for securing our resource.

AWS Secrets Manager: A Secure Solution for Credential Management

Sat, 14 Sep 2024 19:26:10 +0530

Introduction:

We generally store creds in diff ways such as using environment vars, storing them in a file and referring the file in the application (DB connection for example). However they are still stored in plaintext which we can easily peek thru. Also incase a bad actor gains access to the OS, can get all the sensitive information.

Initialize opentofu just as you do with terraform.

AWS Lambda - The Serverless Function

Sat, 27 Apr 2024 19:26:10 +0530

What is Lambda

AWS Lambda is an Amazon serverless computing service meaning we don’t have to manage any ec2 instances. We can just deploy a piece of code that runs automatically based on certain triggers or events and so it is also known as an event-driven computing service.

How AWS ALB Keeps Your Apps in Line!

Sat, 27 Apr 2024 19:26:10 +0530

What is Load Balancer

A load balancer is a tool that helps distribute incoming internet traffic across multiple servers to ensure that no single server becomes overwhelmed.

AWS provides different types of load balancers that help manage web traffic to your applications. The load balancer ensures that your application can handle more visitors without crashing, and it can also automatically route traffic to healthy servers if some servers are having problems.
