Best Practices for Using the AWS Free Tier
Plan Your Usage
Before starting with the Free Tier plan how you intend to use the services. Identify your project requirements and map them to the appropriate Free Tier services. This planning will help you stay within the usage limits and make the most of the available resources.
Automate Resource Management
Use automation tools and scripts to manage your resources effectively. For example you can use AWS CloudFormation to automate the deployment of your infrastructure and ensure consistency across environments. Additionally consider using AWS Lambda for serverless computing which can help you reduce costs by only paying for actual usage.
Take Advantage of Free Training
AWS offers various free training resources, including tutorials, webinars and documentation to help you get started with the Free Tier. Make use of these resources to deepen your understanding of AWS services and learn best practices for managing your infrastructure.
Optimize Resource Usage
Regularly review and optimize your resource usage to stay within the Free Tier limits. For example ensure that you stop or terminate unused EC2 instances and clean up unused S3 buckets or EBS volumes. Additionally consider using AWS Trusted Advisor to get recommendations on cost optimization, security, performance and more.
Set Up Billing Alerts
Set up billing alerts to receive notifications when your usage approaches the Free Tier limits. This will help you avoid unexpected charges and take proactive steps to manage your resources effectively.
