Add logging to AWS CloudWatch

Description:

This ticket aims to integrate AWS CloudWatch logging into the existing Spring Boot application. This will allow us to centralize log data, improve log management, and enable advanced monitoring and troubleshooting capabilities.

Tasks:

• Add the AWS CloudWatch Logs dependency to the project (e.g., aws-cloudwatch-log4j2).
• Configure the application to send logs to CloudWatch. This includes providing AWS credentials and specifying the log group and log stream name.
• Update the application's logging configuration to use the CloudWatch appender.
• Test the integration by generating log entries and verifying they appear in the specified CloudWatch log group and log stream.

Acceptance Criteria:

• The application should successfully send log entries to AWS CloudWatch.
• Log entries should be formatted correctly and contain relevant information.
• The application should handle potential errors gracefully, such as network issues or invalid credentials.

Optional Enhancements:

• Use environment variables or AWS Secrets Manager to store AWS credentials securely.
• Implement log filtering to control which log entries are sent to CloudWatch.
• Create different log streams for different application components or log levels.
• Utilize CloudWatch Logs Insights for querying and analyzing log data.

Notes:

• Ensure the application has the necessary IAM permissions to write logs to CloudWatch.
• Consider using a logging framework like Logback or Log4j 2 for more advanced configuration options.
• This ticket focuses on basic CloudWatch integration. More sophisticated log management strategies can be implemented in future tickets.

Stdout will be written to Cloud Watch by the task, so the application just needs to log to stdout.

Backend integration of Cloud Watch is no longer needed. Ticket can be closed.
