Infrastructure as Code Vs. Infrastructure as a Service.

Anthony Iroham — Wed, 24 Sep 2025 19:34:35 +0000

Infrastructure as Code (IaC) means you use code—like instructions written in a computer file—to build and manage things like servers and networks, instead of setting up every piece by hand. Infrastructure as a Service (IaaS) is when a company rents out computer stuff like servers or storage for others to use over the internet, instead of buying real machines.
What is IaC?
IaC is like writing a recipe for a computer to follow so it always sets up things the same way.

You write down everything you need (servers, settings, size), and the computer builds it exactly as you said.

This makes fixing, changing, or repeating setups really fast and easy—if you need more computers, just let the code run again.

What is IaaS?
IaaS is like renting a computer from a big company that owns lots of computers, instead of buying one for yourself.

Anyone can use these rented computers and storage through the internet, only paying for what is used.

You don’t have to take care of the actual machines—the service provider does that, so you can focus on using the computer for work or games.

Differences Between IaC and IaaS

IaC: Helps you set up and manage computers by writing code
People who want control and automation
Makes things automatic and repeatable with code

IaaS:Lets you rent computers and storage from others
People who need computer power without owning hardware
Makes things available anytime by renting over internet

VERSION CONTROL SYSTEM

A version control system (VCS) is like a magical notebook for computer projects that remembers every change anyone makes so it’s easy to fix mistakes and work together with friends. If several people are building a project, VCS keeps track of who did what and lets everyone bring their ideas together without getting mixed up.

Why VCS Is Useful

Imagine working on a story with friends; if someone accidentally deletes a chapter, VCS lets you go “back in time” and restore the missing part.
You can make different versions called “branches,” so everyone can try out their ideas without changing the main story until everyone is ready.
VCS keeps a diary showing who changed what, so everyone knows what’s happening and can fix problems easily.

How VCS Helps Teams

It saves every step, so mistakes are never permanent—you can always roll back if you need to.
Many people can work together safely without their changes clashing.
VCS helps everyone learn and experiment, because nothing is ever lost; every change is saved in the notebook.

So, version control makes teamwork fun and safe, like having a magic “undo” button and a history book for all your creative and coding projects.

INTRODUCTION TO DEVOPS

Anthony Iroham — Mon, 22 Sep 2025 18:09:06 +0000

DevOps is when the people who make computer programs (developers) and the people who run and take care of those programs (operations) decide to work closely together to do a better job. Before DevOps, these teams often worked apart and didn’t talk much, which sometimes caused problems, like delays or mistakes. With DevOps, both groups team up, share ideas, and use special tools and rules to help each other out so that software can be made faster, with fewer problems.

How DevOps Works

Developers and operations people work as one big team instead of two separate groups.
They help each other build, test, and fix computer programs quickly, so users get updates and new features sooner.
They use tools that automate boring or tricky tasks, which helps reduce mistakes and makes the whole process quicker.
Why DevOps Is Important
It helps computer programs work better and reach people faster.
Everyone on the team feels responsible for making things go well, so they talk more and solve problems together.
By working together, they can fix mistakes faster and make sure programs are safe and reliable.

So, DevOps is all about teamwork, sharing, and using technology to make computer programs better for everyone.

Software Devlopment Livecycle (SDLC)

Software Development Lifecycle(SDLC): This is the step by step plan of making a software: The steps:
1.Planning
2.Requirements/ Analysis
3.Design
4.Implementation/Coding
5.Testing
6.Developmentent
7.Maintainance.
SDLC is used by software developers or development team to design,develope,test and deploy high-quality software.
DevOps is not a single step in the Software Development Lifecycle (SDLC) — it’s more like a way of working that runs through the entire lifecycle.
