It is a tool for building, changing and managing infrastructure in a safe, repeatable way. It is safe to run this command multiple times. Each subnet in your VPC must be associated with a route table. I recommend HCL, as the json format is a targeted machine with auto-generation rather than human-specified code, and Terraform files mostly deal with resources and data sources. This new EBS volume will act as an external hard-disk drive that can be mounted on a particular folder/directory/drive. An internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between our VPC and the internet. Amazon Virtual Private Cloud (Amazon VPC) enables us to launch AWS resources into a virtual network that we have defined. Using a Folder structure, Terraform environments (and their states) are separated by directories and Terraform loads all *.tf files in a directory into one namespace without any specific order. Infrastructure as Code effectively manages your business environment through machine-readable scripts or definition files, rather than through manual processes. That is pretty strong argument especially for a developer like me who does both AWS and Azure. At a high level, Terraform allows operators to use HCL to author files containing definitions of their desired resources on almost any provider (AWS, GCP, GitHub, Docker, etc) and automates the creation of those resources at the time of apply. The --auto-approve option helps us to skip the approval part where terraform program prompts us whether to continue or cancel the process. Here we have used the Amazon Linux 2 AMI (x64) of type t2.micro. The root module is the container of resources that we use together, and the root module can call onto another module. are used as IAS or Infrastructure as Code, but Terraform is best for this because it can even maintain the state of infrastructure. Well, let’s say you are working on a cloud computing platform like AWS, GCP, or Microsoft Azure and wanted to build an infrastructure. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in the configuration files. Its basically the network layering of EC2 instances. When we create a subnet, we specify the CIDR block for the subnet, which is a subset of the VPC CIDR block.
