    What is AWS CloudFormation<\/h2>\n

    AWS CloudFormation is an Infrastructure as Code (IaC) service<\/a> provided by Amazon Web Services that enables developers and system administrators to define, provision and manage cloud infrastructure using code templates. These templates describe the required AWS resources and their configurations in JSON or YAML format.<\/p>\n

    Why we Use AWS CloudFormation<\/h2>\n

    AWS CloudFormation is used to automate the creation and management of AWS infrastructure using code instead of manually configuring resources through the AWS Management Console. In traditional cloud management, developers need to create resources such as EC2 instances<\/a>, S3 buckets, databases, and networking components one by one, which can be time-consuming and prone to human errors.<\/p>\n

    By using CloudFormation, all infrastructure components can be defined in a template file (JSON or YAML). Once the template is executed, CloudFormation automatically provisions and configures all the required resources in the correct order.<\/p>\n

    <\/p>\n

    Components of AWS CloudFormation<\/h2>\n
    1. Templates<\/h5>\n

    A template is the main component of CloudFormation. It is a file written in JSON or YAML format that defines the AWS resources and their configurations.<\/p>\n

    2. Stacks<\/h5>\n

    A stack is a collection of AWS resources that are created and managed together using a CloudFormation template.<\/p>\n

    When a template is executed, CloudFormation creates a stack that includes all the resources defined in the template. Users can create, update, or delete stacks to manage infrastructure.<\/p>\n

    3. Parameters<\/h5>\n

    Parameters allow users to pass input values into templates when creating or updating stacks.<\/p>\n

    4. Resources:<\/h3>\n

    The Resources section defines the actual AWS services<\/a> that will be created by the stack.<\/p>\n

    Examples include:<\/p>\n
