Introduction Docker has become a fundamental tool in modern software development, enabling teams to package applications and dependencies into portable, reproducible containers. But beyond the docker run commands and image pulls lies a rich architecture that powers Docker’s capabilities. In this article, we’ll walk through: Docker’s High-Level Architecture Docker is built on a client–server model: The client and daemon communicate via a REST API (over a Unix socket or TCP). This model allows local or remote interactions. Docker Client ←→ Docker Daemon / Engine│ ││ ├── uses runtime layer (containerd / runc)│ ├── manages images, containers, networks, volumes│ └── interfaces with host OS /…

Think of it like organizing your kitchen: you have ingredients (data), recipes (logic), and the final dish you serve (the user interface). MVC splits these responsibilities into three parts: By keeping these three parts…

What is Virtualization?At its most basic level, virtualization is about encapsulating the capabilities and features of a physical machine in a virtual environment, known as a virtual machine. But why is virtualization needed? Here are a few reasons: Virtualization Structure Virtualization works by using a system that creates a middle layer to manage resources. This lets you run an operating system or application on top of a virtual setup. The OS that runs inside a virtual machine is called a guest OS, while the OS that runs the virtualization system is the host OS. Hypervisors A hypervisor creates a layer between hardware…

In the world of modern software delivery, speed and reliability are everything. Users expect features to roll out fast — without downtime or drama. That’s where CI/CD comes in. In this blog, we’ll break down what CI/CD really is, how it powers DevOps, and walk through a real example so you can see it in action. What is CI/CD? CI/CD stands for: In simple terms: You commit code → It’s built and tested → If successful, it’s deployed automatically This approach avoids the nightmare of last-minute integration hell, ensures bugs are caught early, and allows teams to ship smaller, safer changes more…

Launching a software project is more than writing code; it’s about navigating a landscape of unknowns. Every developer, engineer, and project manager knows that surprises can derail even the best-planned sprint. That’s where a structured approach like SWOT analysis and focused brainstorming becomes invaluable. Let’s break down how these tools help software teams anticipate risks, uncover opportunities, and build more substantial, more resilient projects. What Is SWOT Analysis in Software Projects? SWOT stands for Strengths, Weaknesses, Opportunities, and Threats. It’s a strategic planning tool used by software teams to assess both internal and external factors that could impact a project’s success. Unlike…

Imagine a vast library filled with countless books. To make sense of this collection, each book has specific characteristics that help us categorize and identify it – the title, author, genre, ISBN, publication year, etc. In the world of Database Management Systems (DBMS), these characteristics are known as attributes in DBMS. They are the fundamental building blocks that define the data stored within a database, giving it structure and meaning. So, what exactly are attributes in DBMS? Simply put, an attribute is a characteristic or property of an entity (a real-world object or concept) that we want to store information about.…
