The common cloud migration strategies, often referred to as the "5 R's" of migration, are as follows: Rehost: Also known as "lift-and-shift", this strategy involves migrating existing applications and data to the cloud with minimal or no changes. This is a quick way to leverage cloud benefits while minimizing the impact on application architecture or operations. Refactor: In this approach, the application is reconfigured or modified to leverage cloud-native features, such as auto-scaling and managed databases. Refactoring generally involves minimal changes to the application code and focuses on optimizing it for the cloud for better cost, performance, or reliability. Revise: This strategy involves rearchitecting and modifying the application code (partially or completely) to modernize it in terms of design and functionality. The "revise" approach enables businesses to take full advantage of cloud-native features for improved scalability, resilience, and performance. Rebuild: In this approach, organizations completely redesign and rewrite the applications from scratch using cloud-native technologies and architectures. This allows businesses to create cutting-edge applications optimized for cloud environments, although at the cost of substantial effort and resources. Replace: This strategy involves substituting existing applications with commercial or open-source solutions available in the cloud, often provided as SaaS (Software as a Service). Replacing can streamline costs and resources by leveraging cloud-based solutions instead of maintaining legacy applications in-house.

99

Your team uses Terraform to manage infrastructure. You notice drift—what the Terraform state says exists doesn't match what's actually in AWS. How do you handle it?

Reference answer

Drift happens when infrastructure changes outside of Terraform—someone manually modifies a security group in the AWS console, or a service crashed and autoscaling spun up different instance types. When I detect drift, I have two options. One: update Terraform code to match reality and apply it. Two: destroy what's in AWS and let Terraform recreate it correctly. The choice depends on what changed and whether there's running data. If someone manually changed a security group, I update the Terraform code to reflect that change—we want Terraform to be the source of truth. If it's transient infrastructure like a cache that got spun up, sometimes it's easier to destroy it and let Terraform recreate it. To prevent drift, I prevent manual changes. I restrict IAM permissions so engineers can't manually change production infrastructure—they have to go through Terraform. I also run terraform plan regularly, maybe daily, to detect drift early. I might also use Terraform Cloud's state locking to prevent concurrent changes that cause inconsistency.
