What is a VPC Endpoint in AWS?
A VPC Endpoint is a service that allows you to privately connect your Virtual Private Cloud (VPC) to supported AWS services without using: This means your traffic never leaves the AWS network, which: VPC endpoints are powered by AWS PrivateLink (for interface endpoints), enabling secure and private communication between services. How VPC Endpoint Works Explanation […]
Understanding Serverless and AWS Lambda
What is Serverless? Let’s start with the concept of serverless computing. The term serverless can be misleading. It does not mean there are no servers. Instead, it means you don’t have to manage servers. The cloud provider takes care of infrastructure tasks like provisioning, scaling, and maintenance. This allows developers to focus purely on: For […]
Linux Filesystem Hierarchy
Windows divides data into multiple drives (C:, D:, etc.), Linux follows a structured, single-rooter system. Root directory (/) It contains all essential system directories, configuration files, and user data. Everything in Linux is a file, whether it’s a text document, a directory, a hardware device, or a running process. This directory stores essential system executables […]
In JavaScript, Variables Don’t Have Types — Values Do
While studying JavaScript deeply, I came across an idea explained by Kyle Simpson in You Don’t Know JS: Variables don’t have types. Values have types. At first, this statement feels counter-intuitive, especially if you come from languages like Java, C++, or TypeScript. But understanding this concept is crucial for truly grasping how JavaScript works. Let’s […]
Types vs Interfaces in Typescript
TL;DR; The main concept interfaces offer over types is declaration merging. On the other side, types can do a lot more than interfaces (mapped types, conditional types, etc) Both can define object structure and in simple case both work identically The major differences are — Interfaces have Declaration Merging This same will not work with type […]
Angular Component Communication: A Simple Way Now using input() and model()
After going through some latest updates on Angular, I came across this new way of communication between component. We were using @Input() and @Output() decorators for communication. However, Angular 17 introduced input signals and model() for communication, and I personally loved it’s simplicity. Now, you can bind the property in the template: The input() and […]
What happens when you type a URL in a browser
Nowadays you all are quite good at understanding the digital world and everyone, even my late grandfather, knows what a website is? Reduce some number and those humans know what servers are. Then reduce a more number then those tech related guys know what IP is. In today’s world, people often use mobile apps where […]
Logic Monitor: A Centralized Event-Driven Alerting & Notification Platform
Transforming Fragmented Monitoring into a Unified, Intelligent System The Challenge Different teams relied on different tools to monitor their workloads: This fragmentation created serious operational challenges: We needed a centralized alerting system that could collect all alarms, enrich them, notify the right teams, and create tickets automatically. Our Solution We developed an event-driven monitoring platform—a […]
Modernizing Legacy Integrations with a Serverless Middleware Platform
Bridging 20+ Year Old Systems With Modern Digital Services The Challenge Many government departments still rely on legacy SOAP-based systems built decades ago. As newer services moved to JSON APIs, teams struggled to make both worlds communicate.The existing approach required custom integrations for every service, causing: The goal was clear: Create a secure, scalable, centrally […]
