Disaster recovery strategies (backup, pilot light, warm standby) in AWS - Mini Project: Build & Apply

Disaster Recovery Strategies Setup on AWS

📖 Scenario: You work for a company that wants to protect its website from failures. You will create simple AWS infrastructure setups to practice three disaster recovery strategies: backup, pilot light, and warm standby.

🎯 Goal: Build AWS infrastructure code snippets that represent the backup, pilot light, and warm standby disaster recovery strategies using AWS resources.

📋 What You'll Learn

Create an S3 bucket for backups

Create a minimal pilot light setup with a small EC2 instance

Create a warm standby setup with a running EC2 instance and a load balancer

💡 Why This Matters

🌍 Real World

Companies use disaster recovery strategies to keep their websites and applications running during failures or disasters.

💼 Career

Cloud architects and engineers design and implement disaster recovery plans using AWS resources to ensure business continuity.

1

Create an S3 bucket for backups

Create an AWS CloudFormation resource named BackupBucket of type AWS::S3::Bucket with the bucket name company-backup-bucket.

AWS

# Create an S3 bucket resource named BackupBucket
# Your code here

Need a hint?

Use the AWS::S3::Bucket resource type and set BucketName property.

2

Add a pilot light EC2 instance

Add an AWS CloudFormation resource named PilotLightInstance of type AWS::EC2::Instance with instance type t3.micro and AMI ID ami-0abcdef1234567890.

AWS

Resources:
  BackupBucket:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: company-backup-bucket
# Add a pilot light EC2 instance resource named PilotLightInstance
# Your code here

Need a hint?

Use AWS::EC2::Instance with InstanceType and ImageId properties.

3

Add a warm standby EC2 instance

Add an AWS CloudFormation resource named WarmStandbyInstance of type AWS::EC2::Instance with instance type t3.medium and AMI ID ami-0abcdef1234567890.

AWS

Resources:
  BackupBucket:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: company-backup-bucket
  PilotLightInstance:
    Type: AWS::EC2::Instance
    Properties:
      InstanceType: t3.micro
      ImageId: ami-0abcdef1234567890
# Add a warm standby EC2 instance resource named WarmStandbyInstance
# Your code here

Need a hint?

Use AWS::EC2::Instance with a larger instance type for warm standby.

4

Add a load balancer for warm standby

Add an AWS CloudFormation resource named WarmStandbyLoadBalancer of type AWS::ElasticLoadBalancingV2::LoadBalancer with scheme internet-facing.

AWS

Resources:
  BackupBucket:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: company-backup-bucket
  PilotLightInstance:
    Type: AWS::EC2::Instance
    Properties:
      InstanceType: t3.micro
      ImageId: ami-0abcdef1234567890
  WarmStandbyInstance:
    Type: AWS::EC2::Instance
    Properties:
      InstanceType: t3.medium
      ImageId: ami-0abcdef1234567890
# Add a load balancer resource named WarmStandbyLoadBalancer
# Your code here

Need a hint?

Use AWS::ElasticLoadBalancingV2::LoadBalancer with Scheme set to internet-facing.
