In Kubernetes, Quality of Service (QoS) classes define how resources (CPU and memory) are allocated to pods, especially during times of resource contention. The three QoS classes are:

Guaranteed
Burstable
BestEffort

Here’s a breakdown of the difference between Burstable and Guaranteed QoS classes:

My Agile Experience and Insights

In my previous workplace, Agile was followed and executed seriously. Before that, I used to wonder why time constraints or measurements were necessary in technology, software development, or innovation. But in the real world, especially in a competitive market, if we cannot plan and deliver predictably, we are already too late.
Put simply: daily improvement is today’s innovation.

Key Insights from My Agile Experience

For Agile to be truly successful, a cohesive and stable team is essential. Sticking with the same team over time builds consistency, trust, and velocity.
Here’s how I like to define Agile in simple terms using an analogy:

Capturing JVM heap allocation and comparing it between two executions of a Java application can be super insightful when you're analyzing memory usage, leaks, or performance. Here’s a practical way to do it:

🚀 Step-by-Step Guide

✅ 1. Enable JVM Heap Monitoring

Use the following Java options when running your app to capture memory usage:

db.collectionA.insertMany([
    { "_id": 1, "field1A": "A", "field2A": 100 },
    { "_id": 2, "field1A": "B", "field2A": 200 }

]);

db.collectionB.insertMany([
 { "_id": 1, "field1B": "A", "field2B": 100 },
