Automation of Repetitive Operational Tasks in a Cloud Environment

To improve efficiency and reduce manual intervention, I aim to automate routine operational tasks within a cloud environment (AWS). Our existing infrastructure primarily uses Ubuntu 20.04 servers and our technology stack includes Docker, Kubernetes, and PostgreSQL. Could you assist in:

• Identifying high-impact tasks suitable for automation within this environment (e.g., log rotation, system health checks, application deployments, database backups).

• Recommending automation tools (e.g., Ansible, Terraform, AWS CLI, Python scripting with boto3) and scripting languages (e.g., Python, Bash) for implementation, considering our existing technology stack.

• Providing sample scripts or playbooks for automating these tasks, focusing on practical examples applicable to AWS and Ubuntu 20.04.

• Defining the scope of system health checks to include CPU utilization, memory usage, disk I/O, network latency, and the status of key services (Docker, Kubernetes).

• Clarifying our performance requirements. We aim for automated tasks to execute within a reasonable timeframe (e.g., log rotation should complete within 5 minutes, system health checks within 1 minute) and minimize resource utilization to avoid impacting application performance. Please suggest strategies for optimizing task execution time and resource consumption.

Please present the information in a tabular format, detailing tasks, tools, example scripts/playbooks, and estimated execution times/resource usage.
