AWS Cloudtrail or Amazon CloudWatch What do you prefer:

Amazon CloudWacth provides you the information on the health and performance of your AWS resources and applications, whereas AWS Cloudtrail provides logs of your AWS account activity, including API usage for compliance, risk auditing, and monitoring.

Let’s make it simple to understand, just as the title suggests:

AWS Cloudtrail – AWS CloudTrail is an AWS service that enables compliance, governance, operational, and risk auditing for your AWS account. A user, role, or AWS service performs activities that are recorded as events in the CloudTrail. It keeps track of what you do in your AWS environment and who did what.

AWS CloudTrail is the best option if you wish to perform Detect Anomaly| Troubleshoot | Compliance, Security, and risk auditing.

Amazon CloudWatch – AWS CloudWatch collects data of your activities in the form of metrics, logs, and events, and visualizes it using automated dashboards so you can obtain a unified picture of your AWS application, resources, and other services that run on AWS and your premises. AWS CloudWatch informs you how and with what resources you’re working.

Before you make a decision, make sure you read everything all the way through to ensure you make the best decision possible.

AWS CloudTrail

AWS CloudTrail allows you to see a log of all the activities you’ve done in your AWS environment. CloudTrail is a service that helps you in managing the governance, operational auditing, security, compliance, and risk auditing of your AWS account. It also keeps track of your AWS accounts activities, such as actions performed using the AWS Management portal, AWS SDKs, command-line tools, and other AWS services.

Use of AWS Cloud Trail

  • Detect Anomaly: You can identify sikes or other strange activity and trigger alerts if you see this.
  • Compliance, Security, and Risk Auditing: You can use Cloudtrail in conjunction with other services to identify activities in reaction to specific events, such as when a user tries to alter or do other actions that your organization does not allow, and then trigger a response.
  • Troubleshooting: If you want to find out why certain operations are happening, you may use Cloud Trail, which lets you look over your event history to see which resources were recently created, removed, or modified, as well as who made the changes.

AWS CloudWatch

AWS CloudWatch helps in monitoring various activities of AWS services and resources, as well as tracking your application’s health and performance reports. It collects and tracks metrics and statistics, logs files, set alarms, and reacts to changes in your AWS resource automatically. It monitors and records events every 5 minutes in AWS Cloudwatch, and you can switch to detailed monitoring mode, which collects data every 1 minute.

Use of AWS CloudWatch

  • Automatic Response & Actions: You can set alarms to be triggered when a metric hits a predetermined threshold, which will automatically start a reaction action.
  • Troubleshooting & Monitoring: If your EC2 instances are running slower than usual, you can examine the parameters like CPU utilization, disc read/write operations, network, and so on… Use Cloudwatch metrics for that Ec2 instance to see if it’s an infrastructure issue. Cloudwatch also aids debugging at the application level by assisting you in finding and analyzing your application logs.
  • Resource Allocation: Cloudwatch will help you discover which resources are being used too much or too little, allowing you to better allocate resources and expenses.


Cloudwatch monitors how your AWS resources are doing, whereas Cloudtrail monitors who performed what in your AWS environment. In general, Cloudwatch is more suited for displaying and using resource data, analyzing logs, and generating alarms, whereas Cloudtrail is better suited for tracking activity history, security, and compliance. However, keep in mind that, in most circumstances, both of these services are utilized in tandem to gain greater visibility into the broader AWS environment.
