For Dummies: What is Terraform? How to use it with AWS?
- Terraform is a tool for managing infrastructure as code (IaC) developed by HashiCorp.
- With Terraform, you can write code to define how to build and manage infrastructure resources instead of manually configuring infrastructure.
- AWS is a cloud platform that offers over 200 services to build and scale infrastructure flexibly, quickly, and efficiently.
- Combining Terraform with AWS enables automation of infrastructure management, reducing human error risk, and providing easy rollback options.
- Providers help Terraform connect to and manage resources on third-party services like Amazon Web Services.
- Resources are the actual objects that Terraform creates and manages in AWS, examples include EC2 instances, S3 buckets, and VPC.
- Modules are a set of reusable configurations files for managing complex configurations, organizing Terraform code clearly, and making it easier to maintain.
- Terraform State stores information about the resources it manages. This allows Terraform to track the current state of infrastructure and compare it with the configuration file to apply necessary changes.
- Variables make Terraform configurations more flexible by defining changeable values for different environments or resources.
- Outputs are values you can retrieve after Terraform completes deployment, such as the IP address of an EC2 instance or the name of an S3 bucket.
