Q: How can you use AWS Cost Allocation Tags to manage billing?
AWS Cost Allocation Tags allow you to categorize and track your AWS costs by adding metadata to your AWS resources. To manage billing using Cost Allocation Tags:

Q: What is a Savings Plan and how does it differ from Reserved Instances?
A Savings Plan is a flexible pricing model that offers significant savings on AWS usage, in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a 1- or 3-year term.
Differences from Reserved Instances (RIs):
- Flexibility: Savings Plans apply to a broader set of AWS services and usage types compared to RIs, which are specific to particular instances and regions.
- Commitment Type: Savings Plans are based on a monetary commitment, while RIs are based on instance type and usage.
- Coverage: Savings Plans cover EC2, Lambda, and Fargate usage, whereas RIs are primarily for EC2 instances.
