To enable AWS Config in all accounts and all regions within an AWS Organization, the most operationally efficient method is to use AWS CloudFormation StackSets. This allows you to deploy CloudFormation stacks across multiple AWS accounts and regions from a single CloudFormation template.

Create CloudFormation Template:

The template should include the necessary resources to enable AWS Config, such as the AWS::Config::ConfigurationRecorder, AWS::Config::DeliveryChannel, and AWS::Config::ConfigurationAggregator resources.

Create StackSet:

Open the AWS CloudFormation console at AWS CloudFormation Console.

Choose Create StackSet and upload your CloudFormation template.

Configure StackSet:

Specify the AWS accounts and regions where you want to deploy the stacks.

Set the deployment options, including the execution role and administrator role.

Deploy Stack Instances:

Deploy the stack instances to all specified accounts and regions. This will automatically enable AWS Config in each account and region.

Managing AWS Config Across Multiple Accounts

To reduce the cost of EC2 instances with a 1-year commitment across different regions, purchasing a Compute Savings Plan is the most suitable option.

Compute Savings Plan:

Compute Savings Plans provide the most flexibility and help to reduce your costs by up to 66%, offering savings on a variety of EC2 instance usage.

These plans apply to usage across any AWS Region, and they also apply to AWS Lambda and AWS Fargate usage.

Flexibility Across Regions:

Unlike Reserved Instances, which are tied to a specific instance family and region, Compute Savings Plans provide savings across any EC2 instance usage, regardless of region, instance family, operating system, or tenancy.

This flexibility is ideal for the company's requirement to migrate workloads from the eu-west-1 region to the eu-west-3 region within the commitment period.

Implementation:

Open the AWS Cost Management console.

Navigate to the "Savings Plans" section.

Purchase a Compute Savings Plan with a 1-year term.

To launch EC2 instances when there are no available private IPv4 addresses in the VPC, the SysOps administrator should associate a secondary IPv4 CIDR block with the VPC and create a new subnet for the VPC.

Associate a Secondary IPv4 CIDR Block:

Open the VPC console.

Select the VPC and choose "Actions" -> "Edit CIDRs."

Add a secondary IPv4 CIDR block to increase the number of available IP addresses.

Create a New Subnet:

After adding the secondary CIDR block, create a new subnet within this CIDR block.

This new subnet will provide additional private IP addresses for launching new EC2 instances.
