Showback and Chargeback: Drive Accountability and Savings

Showback and Chargeback offer organizations clarity and responsibility when using cloud resources. These models help departments, teams, or projects grasp cloud expenditures, fostering more mindful resource usage and improved financial oversight. By integrating these models with Shared Resource Allocation and a robust governance framework, organizations can ensure that cloud costs are transparently allocated across teams.

Showback and Chargeback Models

1. Showback Model: The showback model involves tracking cloud expenses for each department or project and providing them with a detailed usage report. This informative method does not charge the department directly but makes their cloud spending visible. It encourages awareness and accountability without requiring cost recovery.

2. Chargeback Model: In the chargeback model, departments or projects receive direct bills for cloud usage. This method enforces financial responsibility and motivates departments to optimize resource consumption since they are accountable for the actual cloud costs incurred.

While both models enhance transparency, Chargeback encourages more cost-aware behavior as departments must manage their own consumption.

In many organizations, cloud resources are often shared among various departments or projects. This can include shared databases, networking, or security services. A clear governance structure is crucial for determining the division of expenses to ensure fair allocation of shared costs. Some allocation methods include:

• Usage-Based Allocation: Costs are allocated based on actual usage, such as data transfer rates or the amount of storage each department utilizes.

• Fixed Percentage Allocation: Set percentages are used based on anticipated usage or the size of each department.

• Project-Based Allocation: Costs are assigned according to the budgets or timelines of specific projects.

Establishing rules and guidelines for allocating shared resources promotes fairness and transparency while helping departments understand their contributions to these shared services.

Starting with cost allocation and chargeback models requires a well-organized approach. To effectively manage cloud expenses, organizations should first create a governance framework. This framework should clearly outline the policies for measuring and reporting costs, such as defining the included cloud services, outlining how data is tracked, and assigning responsibility for managing cost reporting.

Moreover, establishing cost allocation tags to categorize cloud resources is crucial. Tags can help identify the department, project, or environment associated with a resource. Consistent and clear tagging allows for accurate tracking of cloud expenses and facilitates detailed reporting for both showback and chargeback.

Additionally, organizations should consider implementing a cloud cost management tool or platform to monitor, visualize, and report on usage and spending. These tools automate data collection, simplifying the process of accurately allocating costs.

As the organization's cloud usage grows, monitoring costs in detail is essential. This means breaking down cloud services like storage, computing, and networking into smaller units, allowing each department or project to see their usage and associated costs. The aim should be to report unit costs, such as per gigabyte of storage or transaction. This detailed approach helps teams grasp the financial implications of their usage and fosters efforts to optimize resources.

Additionally, established organizations routinely review their cloud costs and chargeback processes. Teams should be trained to analyze reports, spot inefficiencies, and develop strategies for optimizing cloud resource consumption.

Organizations should begin with a strong governance framework to create a robust cloud financial management strategy, utilize tagging for detailed reporting, and gradually advance towards more precise cost tracking and unit cost reporting.
