Choosing between Envoy and HAProxy isn't just about picking a proxy server. It's about deciding which tool will handle your traffic, balance your loads, and keep your services running when everything else wants to crash. If you're a DevOps engineer or system admin weighing these options, you're in the right place.

If you're running workloads in AWS, you've probably heard about VPC Flow Logs. These logs are your eyes and ears for network traffic in your Virtual Private Cloud, and knowing how to check them properly can save you hours of troubleshooting headaches. Whether you're tracking down connectivity issues or monitoring for suspicious activity, this guide will walk you through checking VPC flow logs step by step, with practical examples you can apply today.

Setting up robust observability for your Spring applications is essential for maintaining reliable, high-performing systems. This guide walks you through implementing Spring OpenTelemetry with practical advice for common challenges.

Setting up proper logging is like having a good navigation system when you're driving through unfamiliar territory. For DevOps engineers and SREs managing Java applications, understanding how to configure the built-in java.util.logging framework is essential knowledge that can save you hours of troubleshooting headaches. Let's break down java util logging configuration in a way that makes sense — no fancy jargon, we promise!

The mandate is clear: Do more with less. But in IT, that’s often an impossible equation. Engineers are expected to deliver near-perfect uptime, resolve incidents instantly, and manage an increasingly complex tech stack—all while budgets tighten. Yet, despite your best efforts, you—or your team—are still chasing outages, drowning in alerts, and reacting instead of preventing.

PHP apps can be deceptively simple — until something starts slowing down. Maybe it’s a page load that takes a few seconds too long, or maybe your server costs are creeping up without a clear reason. That’s where performance monitoring comes in. In this guide, we’ll walk through how to monitor and improve the performance of a PHP application. You’ll learn how to use profiling and tracing to identify bottlenecks in your code, and how to optimize your app.

If your network feels sluggish, you're not alone. After years of battling slow connections, dropped calls, and frustrated end-users, I’ve learned one thing: network performance issues always have a root cause. Maybe your VoIP calls keep cutting out. Maybe cloud apps take forever to load. Or maybe your team complains about "the network being slow" — again. The problem? Networks don’t slow down for no reason.

If you need to monitor your application’s health, troubleshoot issues quickly, and ensure compliance with various security policies, application logging is compulsory. Without proper logging, identifying the root cause of failures, tracking suspicious activity, or optimizing application performance will become significantly more challenging, if not impossible.
