CloudFormation best practices are as follows:
- Always give meaningful and relevant names to AWS CloudFormation templates and resources.
- Make sure the resources used by a CloudFormation template exist in the region where it is being executed to create a stack. For example, resources such as an EC2 keypair. It can be also be created dynamically using templates but, if it is hardcoded, make sure it exists in the relevant region.
- Write a template and create a stack for each layer, for example, a separate stack for web servers, application servers, and networks. It will help us minimize downtime and efficiently manage and maintain infrastructures.
- It is a best practice to use a cross-stack reference. It helps us integrate resources from multiple templates into one template, especially when a separate stack is created for each layer.
- It is a best practice...
