Data Preprocessing Guide for Beginners in ML ( Cloned )
Before machine learning (ML) models can generate predictions or insights, the raw data must first be cleaned, organized, and transformed into a suitable format for the model. This process is known as data preprocessing. It is the foundation of every successful ML project. It ensures that the model learns [...]

Tech Burnout: Is It Really Inevitable?
What if the dream job, the one you've always been dreaming of and manifesting ever since, is quietly draining the life out of you? This exhaustion is a known feeling in the tech industry, where the relentless pressure forces professionals and students to push until they hit a wall. [...]
Rise of Microservices in Modern Apps: From One Block to Many
Have you ever thought about the pain of fixing just one small piece of a massive software system without accidentally breaking everything else? Honestly, most of the time, that is almost impossible. That challenge led to the rise of microservices in modern apps. It marked a shift from old monolithic [...]
High-Performing ≠ Massive: The Rise and Progression of Small Language Models (SLMs)
Have you ever needed to find a new charger for your device, only to discover that its voltage wasn’t compatible, causing it not to work or even risking damage? Without checking the actual needs of your device, you’ve probably thought that you could go with what the seller recommends [...]

The Future Is Containerized: Why Every Cloud Engineer Should Care About Docker in 2025
In 2025, software development is moving faster than ever. Businesses demand speed, reliability, and scalability. Cloud infrastructure is no longer optional — it’s the backbone of modern applications, powering everything from streaming platforms like Netflix to AI-driven fintech solutions. In this fast-paced environment, one technology has emerged as a [...]
Chips & Brains: The Psychology of Human-AI Decision Making
Your smartphone just recommended the perfect restaurant, your GPS avoided traffic seamlessly, and your bank approved a loan in seconds—all without human intervention. The speed at which AI operates is awe-inspiring. Yet when the same AI suggests a medical treatment or hiring decision, we suddenly hesitate. This contradiction reveals [...]
Prevent EC2 Downtime: Setting Up Status Check Alarms to Auto-Reboot an Amazon EC2 Instance
When you’re running a production website on an EC2 instance, the last thing you want is for it to unexpectedly go down while you’re focused on other tasks. Without the right monitoring in place, you might not even realize your site has been offline for a while, and repeated [...]

Kinesis Scaling, Resharding and Parallel Processing

Kinesis Resharding enables you to increase or decrease the number of shards in a stream in order to adapt to changes in the rate of data flowing through the stream. Resharding is always pairwise. You cannot split into more than two shards in a single operation, and you cannot merge more than two shards in a single operation. The Kinesis Client Library (KCL) tracks the shards in the stream using an Amazon DynamoDB table, [...]

DynamoDB Scan vs Query

Scan The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. The total number of scanned items has a maximum size limit of 1 MB. Scan operations proceed sequentially; however, for faster performance on a large table or secondary index, applications can request a parallel Scan operation. Scan uses eventually consistent reads when accessing the data in a table; therefore, the result [...]

ECS Task Placement Strategies

A task placement strategy is an algorithm for selecting instances for task placement or tasks for termination. When a task that uses the EC2 launch type is launched, Amazon ECS must determine where to place the task based on the requirements specified in the task definition, such as CPU and memory. Similarly, when you scale down the task count, Amazon ECS must determine which tasks to terminate. A task placement constraint is a rule [...]
