End-to-End AWS Cost Tracking and Management

This task involves creating a new Amazon S3 bucket in a specified AWS region. It's the initial step in setting up a destination for storing Cost and Usage Reports.

In this task, the S3 bucket's policy is updated to grant necessary permissions for AWS Cost and Usage Reports to deliver log files to the bucket, ensuring secure and compliant data storage.

This task involves configuring AWS Cost and Usage Reports (CUR) to direct the reports to the newly created and configured S3 bucket, finalizing the setup for report generation and storage.

Develop a CloudFormation stack to automate the deployment of necessary resources for querying CUR data with Athena, ensuring all components are correctly configured and linked.

Check if the specified CloudFormation stack is already present to avoid redundancy, ensuring that resources are managed efficiently without duplication.

Establish an S3 bucket dedicated to storing results from Athena queries on CUR data; this process includes a check to skip creation if the bucket already exists.

Analyze daily AWS spending by querying the CUR data stored in S3 with Athena, providing insights into overall cost trends and spikes.

Break down daily AWS expenses by service to pinpoint where spending is occurring, using Athena to query detailed CUR data.

Segment and analyze costs for each linked account under a consolidated billing setup using Athena to query CUR data, providing clarity on spending distribution across accounts.

This task retrieves a list of all health checks that have been configured in Amazon's Route53 service. AWS Route53 is a scalable and highly available domain name system (DNS) web service. A health check in Route53 monitors the health and performance of your web applications, web servers, and other resources. By fetching all health checks, users can review, manage, or diagnose the operational status and configuration of their resources, ensuring that the routing policies are working as expected. This can be especially useful for maintaining high availability and redundancy in distributed systems or for troubleshooting issues related to DNS routing.

AWS Route53, Amazon's DNS service, offers health checks to monitor and report the availability of specific resources. Over time, with changes in configurations, deployments, or scaling activities, some of these health checks might become redundant, as they are no longer associated with active resources. Filtering out these unused health checks is an essential maintenance activity. By doing so, users can identify and potentially remove extraneous checks, helping streamline the management of their DNS configurations, optimize costs, and maintain a cleaner, more efficient environment.

This step involves searching through regions to identify Elastic IPs that are not currently associated with any instances. By iteratively querying each region's EC2 service, the script collects details about unattached Elastic IPs, including their public IP addresses, allocation IDs, and regions.

This task involves enumerating and displaying all AWS RDS (Amazon Relational Database Service) instances within an AWS account. This task is essential for management and auditing purposes, providing a clear view of all RDS instances. During this process, the script communicates with AWS services to retrieve information about each RDS instance, including their identifiers, status, and any other relevant details. This information is crucial for administrators to understand their AWS infrastructure's state, aiding in further actions like modification, deletion, or analysis of the RDS instances.

This task identifies Amazon RDS instances that are underperforming or underutilized in terms of CPU usage. By utilizing Amazon CloudWatch metrics, users can monitor and assess the CPU performance of their RDS instances over a specified period. By setting a CPU utilization threshold, they can filter out instances that consistently operate below this limit, indicating potential over-provisioning or underuse. Highlighting these low-utilization instances aids organizations in optimizing their AWS resource allocation, ensuring cost efficiency and facilitating informed decisions about scaling or decommissioning certain database resources.

This process retrieves a list of all Amazon Redshift clusters within an AWS account. Amazon Redshift is a fully managed data warehouse service in the cloud that allows users to run complex analytic queries against petabytes of structured data. By fetching all Redshift clusters, users can gain insights into the number of active clusters, their configurations, statuses, and other related metadata. This information is crucial for administrative tasks, monitoring, and optimizing costs and performance.

This task pertains to identifying Amazon Redshift clusters that exhibit consistently low CPU utilization over a predefined time span. By leveraging Amazon CloudWatch metrics, organizations can detect underutilized Redshift clusters. Recognizing such clusters provides valuable insights, allowing teams to make informed decisions about potential downscaling, resource reallocation, or other optimization measures to ensure efficient cloud resource usage.

This task retrieves a list of all secrets stored in the AWS Secrets Manager for your account. AWS Secrets Manager is a service designed to safeguard sensitive information such as database credentials and API keys. By executing this task, users will obtain a comprehensive list of secret names or ARNs, aiding in audit, management, or automation processes. Note that this task will list the secrets' identifiers, but not their actual values. To fetch a specific secret's value, additional steps involving the get_secret_value method are required. Ensure you have the appropriate AWS IAM permissions before executing this task.

This task aims to pinpoint secrets within AWS Secrets Manager that haven't been accessed for a specified duration, such as the past 90 days. Over time, certain secrets may not be referenced or utilized, indicating they may no longer be needed. By identifying these inactive secrets, organizations can assess their continued relevance, streamline their secrets inventory, and enhance security by minimizing potential exposure points. Before taking any action based on the results, it's crucial to review the list and ensure no critical secrets are mistakenly categorized as "unused."

This task is designed to systematically retrieve and enumerate all CloudWatch log streams present in specified AWS regions. It offers a detailed snapshot of the existing log streams, enabling users to understand their logging landscape across various AWS services and applications.

This task examines CloudWatch log streams to identify those that have been inactive for a specified duration. By pinpointing these dormant streams, the task aids in maintaining a cleaner, more efficient logging environment and can subsequently assist in reducing unnecessary storage costs associated with retaining outdated logs on AWS CloudWatch.

This task involves using the boto3 to programmatically iterate over all AWS regions, retrieve, and list details of all Network Address Translation (NAT) gateways present in an AWS account.

This task identifies AWS NAT gateways that have not transferred any data in the past week or threshold, deeming them as "unused", and filters them out for potential optimization or deletion.

Amazon Elastic Compute Cloud (EC2) is a service offered by Amazon Web Services (AWS) that provides resizable compute capacity in the cloud. Through Boto3's EC2 client, the describe_instances() method provides detailed information about each instance, including its ID, type, launch time, and current state. This capability assists users in effectively monitoring and managing their cloud resources.
