Which AWS services can facilitate organizational change management as part of the Reliability pillar of AWS Well-Architected Framework?

The AWS Well-Architected Framework's Reliability pillar focuses on the ability of a system to recover from infrastructure or service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues.

Several AWS services can facilitate organizational change management as part of this pillar:

1. AWS Config: This service provides a detailed inventory of your AWS resources and their current configuration, and continuously records configuration changes. This can help in managing changes to your AWS resources.

2. AWS CloudTrail: This service enables governance, compliance, operational auditing, and risk auditing of your AWS account. It helps you log, continuously monitor, and retain account activity related to actions across your AWS infrastructure.

3. AWS CloudFormation: This service helps you model and provision AWS and third-party application resources. You can manage and provision your infrastructure and applications in a safe, predictable manner.

4. AWS Systems Manager: This service gives you visibility and control of your infrastructure on AWS. It provides a unified user interface so you can view operational data from multiple AWS services and automate operational tasks across your AWS resources.

5. AWS Service Catalog: This service allows organizations to create and manage catalogs of IT services that are approved for use on AWS. It helps to achieve consistent governance and meet your compliance requirements, while enabling users to quickly deploy only the approved IT services they need.

6. AWS Trusted Advisor: This service provides real-time guidance to help you provision your resources following AWS best practices. It helps you to observe best practices for the use of AWS by inspecting your AWS environment with an eye toward saving money, improving system performance and reliability, and closing security gaps.

Remember, the key to effective change management is not just the use of these tools, but also the establishment of good governance and operational practices.
