AWS Serverless Microservices with Patterns and Best Practices - AWS Cloud Formation

AWS CloudFormation is a service that models, provisions, and manages AWS and third-party resources by treating infrastructure as code. It automates the setup of AWS resources using template files, enabling predictable and repeatable infrastructure deployments. CloudFormation supports a wide range of AWS services and allows users to create and manage resources as a single unit or stack. The process involves creating a template file, saving it locally or in an S3 bucket, and using AWS CloudFormation to provision the infrastructure. This service simplifies infrastructure management, making it highly reliable, scalable, and cost-effective.
