• Provisioning your infra through code

• When you can do that from the Azure console, login to the portal and create, drag, and drop.
• Why take the pain of writing code for drag and drop?

• Let's assume you have to provision the infra to deploy a three-tier application Time taken: 2 hours

it's good for a personal project or when you are learning something

• What if you are working somewhere in a company and let's say you have 4 environments? Time taken: 8 hours no big deal? right

• How about 100s of servers to be deployed? Tricky? That's not it
• To save the cost , decommission every day(not possible) keep running and keep accumulating the cost
• Identical environment, works on my machine
• Automate the provisioning, manage and destroy the infra
• Reliability, efficiency, and security?

• Consistent environment
• Easy to track cost
• Write once, deploy many (single code base)
• Time saving
• Human error
• Cost saving
• Version control, changes are tracked in git
• Automated cleanup/scheduled destruction
• Easy to set and destroy
• The developer can focus on app development
• Easy to create an identical production environment for troubleshooting

IaaC tool that helps do all these tasks

Write your terraform files --> Run terraform commands --> Call the target cloud provider API to provision the infra using Terraform Provider

Phases: init --> validate --> plan --> apply --> destroy
