Prerequisites:

Before you begin, ensure you have the following prerequisites in place:

• Basic knowledge of AWS services (EC2 and CloudFormation).
• An active AWS account.
• Equipped with necessary vCPU quota for your selected instance type. Read how to increase AWS vCPU quota here: https://meetrix.io/articles/how-to-increase-aws-quota/
