what is diff cloud formation vs terraform, release management like blue green etc.

Question

Accepted Answer

CloudFormation and Terraform are both infrastructure as code tools, while blue-green release management is a deployment strategy.

CloudFormation is a service provided by AWS for creating and managing AWS resources using templates written in JSON or YAML.
Terraform is an open-source tool by HashiCorp that allows you to define and provision infrastructure using a declarative configuration language.
Blue-green deployment is a strategy where you have two identical production environments, with one serving live traffic while the other is idle. You switch between them for deployments.
Blue-green deployment helps in achieving zero downtime deployments and easy rollback in case of issues.
