cloudformation vs codedeploy: What are the differences?

# Introduction
In this Markdown code snippet, we will compare the key differences between AWS CloudFormation and AWS CodeDeploy.

1. **Deployment Automation**: AWS CloudFormation is primarily used for infrastructure as code, allowing users to define and provision resources in a declarative manner, while AWS CodeDeploy is focused on automating the deployment of applications to instances or serverless environments.
2. **Resource Management**: CloudFormation manages the creation, update, and deletion of AWS resources, making it ideal for managing infrastructure changes in a repeatable and predictable manner. On the other hand, CodeDeploy focuses on deploying applications to instances or services without managing the underlying infrastructure.
3. **Scalability**: CloudFormation provides features for scaling resources based on conditions or metrics, allowing users to automate resource scaling. In contrast, CodeDeploy does not directly handle resource scaling but can be integrated with other AWS services to achieve scalability.
4. **Rollback Capabilities**: CloudFormation offers rollback capabilities, enabling users to revert changes if a deployment fails or encounters errors. CodeDeploy also supports rollbacks but focuses more on application deployments rather than infrastructure changes.
5. **Integration**: CloudFormation integrates with various AWS services for managing resources, creating stacks, and ensuring infrastructure consistency. CodeDeploy integrates with other AWS services, such as AWS CodePipeline, to automate the entire software release process.
6. **Application Lifecycle Management**: CodeDeploy facilitates a range of deployment strategies like blue/green deployments, in-place deployments, and canary deployments, streamlining the application lifecycle management process as compared to CloudFormation which is more focused on infrastructure management.

In Summary, CloudFormation is concentrated on infrastructure management through declarative resource provisioning, while CodeDeploy focuses on automating application deployments and lifecycle management.
