Security
- Enable Multi-Factor Authentication (MFA): Protect root account and IAM users by enabling MFA to add an extra layer of security.
- Rotate Access Keys Regularly: Regularly rotate access keys for IAM users to reduce the risk of compromised credentials.
- Apply Least Privilege Principle: Ensure IAM policies grant the minimum permissions necessary for users to perform their tasks.
- Encrypt Data at Rest and in Transit: Use AWS encryption features to protect sensitive data both at rest and during transmission.
- Monitor and Audit Account Activity: Enable AWS CloudTrail and Amazon CloudWatch to monitor and log account activity for security audits.
Cost Optimization
- Right-Size EC2 Instances: Regularly review and adjust EC2 instance types and sizes to match current usage requirements and reduce costs.
- Use Reserved Instances and Savings Plans: Purchase Reserved Instances and Savings Plans for predictable workloads to achieve cost savings.
- Delete Unused Resources: Identify and remove unused resources, such as EBS volumes, snapshots, and idle instances, to avoid unnecessary charges.
- Implement Auto Scaling: Use Auto Scaling to adjust capacity automatically based on demand, ensuring efficient resource utilization.
- Leverage Spot Instances: Utilize Spot Instances for non-critical workloads to benefit from significant cost reductions.
Performance
- Distribute Workloads Across Regions: Use multiple AWS regions to distribute workloads and reduce latency for global users.
- Optimize Storage Solutions: Choose the appropriate storage solution (e.g., S3, EBS, Glacier) based on performance requirements and cost-effectiveness.
- Use Content Delivery Networks (CDNs): Employ Amazon CloudFront to deliver content with low latency and high transfer speeds.
- Enable Read Replicas for RDS: Improve database performance and availability by using Read Replicas for read-heavy applications.
- Monitor Performance Metrics: Regularly monitor performance metrics using Amazon CloudWatch to identify and address performance bottlenecks.
