What tasks have you performed using Terraform?

Worked with Terraform for managing cloud infrastructure in AWS and Yandex.Cloud.

Main tasks:

• Automatic creation and configuration of virtual machines (EC2, Compute Cloud).
• Management of network resources (VPC, subnets, security groups, route tables).
• Deployment and configuration of databases (RDS, Managed Service for PostgreSQL).
• Management of data storage (S3, Object Storage as backend for Terraform state).
• Creation and configuration of load balancers (ALB, NLB).
• Deployment of Kubernetes clusters (EKS in AWS, Managed Service for Kubernetes in Yandex).
• Management of DNS records.
• Modularization of infrastructure for code reuse.
• Use of variables and ternary operators for flexible configuration.
• Application of terraform state to track infrastructure state.
• Integration of Terraform with CI/CD pipelines (GitLab CI, Jenkins).

Terraform features used:

• terraform init
• terraform plan
• terraform apply
• terraform destroy
• terraform state
• Use of providers for AWS and Yandex.Cloud.
• Application of modules.
• Management of state backends (S3, Object Storage).
• Use of HCL (HashiCorp Configuration Language).

Example code snippet for creating an EC2 instance:

resource "aws_instance" "web_server" {
  ami           = "ami-0abcdef1234567890" // Image ID
  instance_type = "t2.micro"

  tags = {
    Name = "WebServer"
  }
}
