Amazon CloudWatch is a monitoring service that provides data and actionable insights to monitor applications, understand system-wide performance, and optimize resource utilization.
Not only does it provide a clear overview of your AWS resources, but it also allows you to set alarms and react to changes in your AWS environment, enabling you to manage and keep your applications running smoothly.
II. AWS CloudTrail
AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. CloudTrail provides event history of your AWS account activity, such as actions taken through the AWS Management Console, AWS SDKs, command-line tools, and other AWS services.
This tool essentially logs all actions made within your AWS environment and stores them, providing a complete record of changes, including who made them, the time they were made, and their associated parameters.
III. AWS Audit Manager
Audit Manager is a service that helps you continuously audit your AWS usage to simplify how you assess risk and compliance. AWS Audit Manager assists in collecting evidence of AWS resource configuration, fully automating evidence collection to make it easier to conduct audits.
IV. AWS Config
AWS Config provides a detailed inventory of your AWS resources and their current configuration while continuously recording changes. This enables you to review changes in configurations and relationships between AWS resources, dive into detailed resource configuration histories, and determine your overall compliance against the configurations specified in your internal guidelines.
V. Access Reports
Access reports are an integral part of any governance and compliance workflow. AWS Identity and Access Management (IAM) provides access reports that give information about the entities in your AWS environment (users, groups, and roles), including their permissions and how those permissions are used.
Utilizing these services in combination aids in maintaining a strong grip over your governance and compliance. For example, you might use CloudWatch to monitor your ecosystem, using CloudTrail to track changes made. Any discrepancies or potential breaches picked up can be addressed in real time, and a record of all actions is maintained. Detailed access reports can be created to identify who has access to an environment at an individual level, identifying irregularities and potential security breaches.
In conclusion, AWS offers a robust suite of services that can assist in maintaining governance and compliance. For the AWS Certified Cloud Practitioner (CLF-C02) exam, it’s crucial to understand how each of these services functions and their potential applications in a variety of situations. By comprehending their capabilities, you can effectively deploy them within your AWS environment to maintain security, compliance, and overall system health.
