Introduction to AWS CloudFormation

AWS CloudFormation is a powerful infrastructure provisioning tool provided by Amazon Web Services (AWS). It allows you to define your AWS infrastructure as code using a declarative JSON or YAML template.

With CloudFormation, you can describe your entire infrastructure stack including resources, dependencies, and configurations in a single template. This makes it easier to manage and provision resources in a consistent and reliable manner.

CloudFormation provides a wide range of resource types that you can include in your templates, such as EC2 instances, RDS databases, S3 buckets, and more. You can also define parameters and mappings to make your templates more flexible and reusable.

Let's take a look at a simple CloudFormation template that defines an EC2 instance:

1Resources:
2  MyEC2Instance:
3    Type: AWS::EC2::Instance
4    Properties:
5      ImageId: ami-0c94855ba95c71c99
6      InstanceType: t2.micro
7      KeyName: my-key-pair
8      SecurityGroupIds:
9        - sg-0123456789abcdef0
10      SubnetId: subnet-0123456789abcdef

In this example, we define an EC2 instance resource with specific properties, such as the Amazon Machine Image (AMI) ID, instance type, key pair, security group IDs, and subnet ID.

Using CloudFormation, you can deploy this template to create the EC2 instance with the specified configuration.

AWS CloudFormation simplifies the process of infrastructure provisioning and management by allowing you to define your infrastructure as code. This brings several benefits:

• Automated Provisioning: CloudFormation enables you to automate the provisioning of your infrastructure resources by defining them in a template.
• Consistency: With CloudFormation, you can ensure that your infrastructure resources are provisioned in a consistent manner across different environments and regions.
• Reproducibility: Your infrastructure stack defined in a CloudFormation template can be easily reproduced or replicated as needed.
• Version Control: Your CloudFormation templates can be stored and version-controlled using tools like Git, allowing you to track changes and collaborate with other team members.
• Scalability: CloudFormation provides support for scaling resources, allowing you to easily adjust the capacity of your infrastructure.

CloudFormation is a powerful tool that helps you manage your AWS infrastructure as code. It facilitates infrastructure provisioning, ensures consistency, and allows for easier maintenance and collaboration.

class Main {

  public static void main(String[] args) {

    // Replace with your Java logic here

    for(int i = 1; i <= 100; i++) {

      if(i % 3 == 0 && i % 5 == 0) {

          System.out.println("FizzBuzz");

      } else if(i % 3 == 0) {

          System.out.println("Fizz");

      } else if(i % 5 == 0) {

          System.out.println("Buzz");

      } else {

          System.out.println(i);

      }

    }
