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
