AWS offers two tiers of Trusted Advisor. The first tier, Basic, is available to all AWS users at no additional cost and provides access to a set of core checks and recommendations. The second tier, Business, requires an AWS Business or Enterprise Support plan subscription and unlocks advanced checks and enhanced support options.

The Basic tier of Trusted Advisor is free for all AWS users. It offers fundamental checks and recommendations across the five pillars mentioned earlier. However, access to the Business tier requires an active AWS Business or Enterprise Support plan, which comes with an associated cost.

1. Developer Tier: This tier is recommended for users who are experimenting or testing in AWS. It provides a basic level of support and access to Trusted Advisor's Service Quota and basic Security checks. The priority for response times is relatively lower, with general guidance provided within 24 hours and system-impaired support within 12 hours.
2. Business Tier: The Business tier is the minimum recommended tier for users with production workloads in AWS. It offers enhanced technical support, including access to Cloud Support Associates during business hours. Users in this tier have access to the full set of Trusted Advisor checks, covering all pillars, and can expect prioritized responses for their support cases. The response times are faster than the Developer tier, with production system down issues addressed within 1 hour.
3. Enterprise On-Ramp Tier: This tier is suitable for users with production and/or business-critical workloads in AWS. It provides 24/7 support with unlimited cases and unlimited contacts, including access to AWS Support App in Slack. Users can also benefit from architectural guidance and consultative reviews based on their applications.
4. Enterprise Tier: The Enterprise tier is recommended for users with business and/or mission-critical workloads in AWS. It offers the highest level of support, including rapid response times for critical issues. In addition to the full set of Trusted Advisor checks, users in this tier can access AWS Support API and receive proactive programs and self-service features.
