Modernizing Legacy Cloud Infrastructure with Terraform

Multi-Tool Approach (Brainboard | Former2 | cf2tf)

Overview
A standardized approach to convert existing cloud infrastructure and CloudFormation templates into Terraform, using visual design, infrastructure discovery, and CLI-based tools for safe and efficient IaC adoption.

What This Document Is Used For
Brainboard: Visual drag and drop tool for designing cloud architectures; auto generates Terraform code.
Former2: Scans live AWS resources and reverse-engineers them into CloudFormation CDK CDKTF Terraform code + diagrams.
cf2tf: CLI tool that converts existing CloudFormation templates to Terraform

BRAINBOARD

Introduction:
Former2 allows you to generate Infrastructure-as-Code outputs from your existing resources within your AWS account. By making the relevant calls using the #AWS JavaScript SDK, Former2 will scan across your infrastructure and present you with the list of resources for you to choose which to generate outputs for.
Former2 allows you to generate Infrastructure-as-Code outputs from your existing resources within your AWS account check Below link

NOTE: Former2 is support only in AWS cloud check and use this iam Read Only Access work here i this tool These tools save time, but manual review is still important for accuracy. Pre-requisites :
● an Aws account with appropriate permissions.
● Access key and secret access keys should be created READ ONLY within the aws account. it works
Procedure :
Step-1 : Open a google chrome window and type former2 in the search bar. Click on the first link, it will navigate up to the former2 dashboard.

Step-1: Open a google chrome window and type former2 in the search bar. Click on the first link, it will navigate up to the former2 dashboard.

Step2 : Setup your AWS ACCESS KEY and SECRET ACCESS KEY in the credentials and click on scan account to get connected with your aws account. Read only access worksOnce dashboard opens click on setup and click on credentials

Step-3 : Once the Aws Account gets connected with the former2 tool. select your region and view the resources within the account. Scan Select your region on the top right. My selection is us-east-1. Click Search/Search again -> go to dash bode

click on --> go to dash bode

Step-4 : select the services Click the Generate button on the top of the page

Step-5 : And … Magic You will be taken right away to the Output section, with a CloudFormation template ready for you IAC and CDK,CDKTF,PULIMI

Note: it supports the AWS cloud and it is used for existing resources within your AWS account. Not a full Terraform replacement. Manual review is required, and some services may not convert fully.
