📖 What is AWS Trusted Advisor?
AWS Trusted Advisor is an online tool analyzing your AWS infrastructure against best practices. It provides recommendations across five categories: Cost Optimization, Performance Improvement, Security Checks, Fault Tolerance, and Service Limits, helping to reduce risks and improve efficiency.
"Trusted Advisor checks are not prescriptive fixes, but rather recommendations. Focus on understanding the *categories* of checks. It is a reactive tool, identifying potential issues, not preventing them. Do not confuse it with AWS Config, which is a configuration management service."

🔑 What are the Key Concepts of AWS Trusted Advisor?
- ▸ Trusted Advisor provides recommendations in five categories: Cost Optimization, Performance Improvement, Security, Fault Tolerance, and Service Limits.
- ▸ It's a *reactive* tool; it identifies potential issues after resources are provisioned, unlike proactive services like AWS Config.
- ▸ Recommendations are not mandatory fixes; they require manual review and implementation based on your specific needs.
- ▸ Trusted Advisor checks are free, but more detailed, real-time data is available with a Business or Enterprise Support plan.
- ▸ Understanding the scope of each category is crucial – Security checks focus on IAM, encryption, and access control best practices.
