The Economics of AI Infrastructure: Understanding AWS AI Factories
Artificial intelligence has shifted from being a software innovation challenge to becoming an infrastructure challenge. Organizations no longer struggle primarily with model design. Instead, organizations are increasingly challenged by compute density, energy consumption, networking scale, and operational complexity when deploying modern AI systems. As large-scale generative AI systems become [...]
Deploying an AWS Application Load Balancer (ALB) Using Terraform
If you’ve tried building an ALB manually in the AWS Console, you already know the drill create a VPC, configure subnets, set up security groups, launch EC2 instances, create a target group, add listeners, and then double check everything because one small misconfiguration can break the whole setup. It [...]
How to Break Into Tech (With Security in Mind)
Let’s talk honestly for a second. If you want to break into tech securely, you need to think differently from the start. A lot of people say they want to “break into tech,” but very few think about structure, architecture, and security from day one. What they usually mean [...]
Stop Running OpenClaw on Your Laptop: How I Built a Secure Personal AI Assistant Using Amazon Bedrock
I'll admit. The first time I heard about OpenClaw and its features, I was obsessed. The idea of having an AI that could actually do stuff rather than just giving responses to prompts felt like living in the future. As a university student, it’s a given that I have [...]
Improving Application Security with AWS Security Agent
Modern software teams are very fast today. Code is pushed daily. Pipelines deploy automatically. Features reach users quickly. This is the success of DevOps. But security often does not move at the same speed. In many organizations, security reviews are still scheduled monthly or quarterly. Penetration tests require coordination. [...]
Real-time Personally Identifiable Information (PII) Redaction Pipeline with S3 + Lambda + Comprehend
In my previous article, I demonstrated how to use the Amazon Comprehend console to manually detect and redact Personally Identifiable Information (PII) from text files. While this hands-on method is excellent for learning the fundamentals of PII detection, it’s not practical in real-world, high-volume environments where speed and accuracy [...]
Are AI Engineers the New Full-Stack Developers?
Something has been quietly shifting in the tech industry. Job titles that used to sit in completely separate corners of a hiring platform are starting to blur together, and engineers on both sides are feeling it. The full-stack developer who's suddenly expected to integrate LLMs. The AI engineer who's [...]
The “Stateful” Video: Moving from Random Prompts to Semantic Consistency
In the early days of GenAI, creating a video was like launching a Lambda function with no database—every time you ran it, the AI "forgot" what the character looked like, what they were wearing, or even the laws of physics in the previous scene.As we hit 2026, the industry [...]
Reinforcement Fine-Tuning in Amazon Bedrock: A Practical Guide for Enterprise AI
Large language models are powerful, but power alone is not enough for enterprise AI. A model may generate fluent responses, yet still miss your company’s tone, fail structured validation rules, or produce outputs that are technically correct but operationally unusable. The real challenge is not just making models smarter, [...]
Don’t Install OpenClaw! (Unless You Read This First)
If you have been on Twitter, TikTok, or GitHub recently, you have probably seen the hype. Clawdbot (now rebranded as OpenClaw) promises something bold: a self-hosted AI employee that runs on your Mac Mini, has terminal access, and takes instructions through messaging platforms like Telegram. It sounds powerful. It [...]

Don’t Learn AWS Until You Know These Things

Learning AWS is like trying to drink from a firehose. At least, that's how I remember it felt when I jumped into AWS years ago as a non-IT guy. I often bounced around between different articles and Youtube videos, struggling to make sense of all the concepts. One moment, I'd be focusing on an EC2 tutorial but then realize I needed to understand VPCs first, so I'd click over to a video about networking. [...]

Creating And Mounting An Azure File Share

A file server provides organizations with a system to centrally store, manage, and access files within a network, such as documents, images, videos, logs, etc. With file servers, users can easily share and collaborate on files with others. Azure Files is a fully managed file share solution that aims to replace or supplement on-premises file servers. It is a platform as a service (PaaS) offering by Microsoft Azure that is accessible by SMB and [...]

Deploying Docker Images To Azure Container Apps

Containers, cloud-native, and microservices are all used in modern software development and deployment. A container is a standalone executable package that contains everything needed to run a piece of software, creating an isolated environment for the application. While microservices are an architectural paradigm for developing applications composed of small, independent services. This enables teams to autonomously build, deploy, and grow their services, increasing the speed and agility of the development process. In Microsoft Azure, [...]

Reduce The Cost Of Your Lambda Functions With Event Filters (Part 2 of 2)

Introduction In the first part of this post, we covered the concept behind event filtering in AWS Lambda and learned how it could help you save money by invoking functions only when necessary. Now it's time to put that knowledge into practice. In this part 2, we’ll see event filtering in action using Amazon Simple Queue Service (SQS) as the event source. Overview A user sends a JSON message to the SQS queue. Event [...]

Reduce The Cost Of Your Lambda Functions With Event Filters (Part 1 of 2)

Problem statement You are primarily billed based on how long your Lambda functions run and how often it is invoked. This is why AWS Lambda is great for scheduled jobs, short-duration tasks, and event-based processes. But does this mean you shouldn’t use them for high-volume traffic applications? Well, the short answer is... it depends. Whether or not to use AWS Lambda for high-volume traffic workloads ultimately depends on the requirements of your application and [...]

SFTP On Your Ubuntu EC2 Instance – Quick and Simple Setup

SFTP, which stands for Secure File Transfer Protocol, is a method of transferring files between computers. It operates over SSH (Secure Shell) and uses public-key cryptography for authentication. This means that your login credentials and file transfers are encrypted, making them much more secure than the traditional FTP (File Transfer Protocol). Why SFTP over SCP? SFTP and Secure Copy Protocol (SCP) are both network protocols that you can use for transferring files. They also [...]

Automate Resources In Azure Using ARM Templates

Infrastructure as Code (IaC) is a method of running IT infrastructure that automates, configures, and manages systems and networks using scripts or code. It can work with a variety of file formats, including JSON and YAML. YAML (YAML Ain't Markup Language) is a data serialization format that is commonly used in Ansible, Kubernetes, and other tools. While JSON (JavaScript Object Notation) is a popular data interchange format that is frequently used in AWS CloudFormation, [...]
