Insights

Technical ideas written for recovery decisions.

These summaries are drawn from the supplied Dockfield source articles and architecture briefs. They separate infrastructure reproducibility, data recoverability and incident-time trust.

After ransomware, the latest Terraform snapshot may be the wrong one

Why an approved artifact can still be unsafe for a specific incident, and how compromise-time selection aligns infrastructure with a trusted data point.

Ransomware

DR-as-Code: rebuilding the environment around the data

Why backup and workload recovery are not the same as reconstructing networking, security, compute and dependencies.

Concept

RDS and Aurora point-in-time recovery vs AWS Backup

Point-in-time recovery for operational precision, AWS Backup for governance, and DR-as-Code for the surrounding platform.

Data

Reverse-engineering AWS into Terraform for legacy estates

From Boto3 discovery to dependency-safe Terraform, including ID-to-reference translation and VPC-first validation.

Terraform

Custom AWS disaster recovery with manual failover

Same-account and multi-account recovery, scheduled capture, target deployment and controlled DNS switching.

Architecture

ECS Amazon Linux 2 to Amazon Linux 2023

Progressive capacity-provider placement, canary weights and state decoupling through EFS or external storage.

ECS
Editorial principle: recovery claims need scope and evidence. A configuration interval is not automatically the application's data RPO, and an approved artifact is not automatically safe for every incident.
