Terraform State Migration: Seamlessly Moving from AWS S3 to Google Cloud Storage

Ashish Sharma — Wed, 29 Jul 2026 07:43:10 +0000

Introduction: What if the single source of truth for your entire infrastructure lived in the wrong cloud? For years, our Terraform state lived in an AWS S3 bucket while our infrastructure increasingly ran on Google Cloud Platform. That split created cross-cloud dependencies, IAM complexity, and a growing mismatch between where we managed infrastructure and where […]

DNS as Code in Action: Lessons from a Client Project with NS1 and Terraform

Karandeep Singh — Sat, 31 Jan 2026 11:57:43 +0000

Introduction DNS is rarely the first thing teams modernise. In most client environments we work with at To The New, CI/CD, cloud infrastructure, and observability mature quickly. DNS, however, often remains manually managed through dashboards, handled by a few people, and changed mostly during incidents. That gap usually goes unnoticed until traffic needs to be […]

Karandeep Singh — Tue, 26 Aug 2025 16:16:33 +0000

Introduction If you’re still running MySQL 5.7 on Amazon RDS, it’s time to act. AWS started charging for Extended Support in March 2024. By mid-2025, that charge is no longer theoretical, and paying for it is kind of unacceptable. You’re likely already paying for it, and the cost will double by the end of this […]

Upgrading the Terraform AWS Provider: Painful, But Worth It

Karandeep Singh — Tue, 19 Aug 2025 19:09:12 +0000

Introduction If you’re using Terraform for IAAC with AWS, you might have probably declared the provider like this in your code: provider "aws" { region = "us-west-2" } And it worked.

Terraform 1.5 Import Block: Eliminate Manual Imports and Streamline IaC

Karandeep Singh — Mon, 26 May 2025 07:04:32 +0000
