Top 8 Cloud Cost Management Tools | Harness Blog

Regardless of whether you use a single cloud service provider like AWS, GCP, or Azure, or you run in a multi-cloud or hybrid cloud environment, you’re almost certain to be spending money on resources that you’re not using. If you’re a developer or in engineering, you’re empowered to innovate and move quickly, and that means spinning up cloud resources. If you’re in finance or cloud FinOps, you’re probably on the receiving end of those freely spun-up resources in the form of your cloud bill. Between the two sides of the coin, cloud cost monitoring and management is the name of the game.

Companies often find that the biggest contributors to their cloud costs are unused or overprovisioned resources. Due to a plethora of reasons, resources that are spun up can end up idly sitting by waiting to be more fully utilized, or resources can become unallocated or ‘zombie’ resources. You can read more about the most common contributors to cloud spend and how to reduce cloud cost in an article I’ve recently published. In any case, getting the visibility into where money is being spent is naturally the first step of the journey, with smart cloud cost optimization being the second leg.

Whether you’re trying to get a hold of rampant cloud spending, purchase reserved capacity to optimize your spend based on historical usage data, or drive cultural change across your organization with regards to cloud cost management across your cloud services, there are tools out there that can make your life easier. This post will cover some of the most popular or common cloud cost monitoring tools you’ll run into and showcase the pros and cons of each.

There are many cloud cost management methods that are most appropriate for you, depending on your scale and complexity. You’ll want to familiarize yourself with some of the cloud cost management methods out there to help you pick the best tool for your use case.

Tool #1: Harness Cloud & AI Cost Management

Harness Cloud & AI Cost Management is a tool designed for the modern-day software company in the cloud. Engineering, finance, and any other team has the capability to understand where costs are coming from and be proactive about visualizing, managing, monitoring, and optimizing their cloud costs, both in a silo and collaboratively.

This tool is useful for finance, engineering, and FinOps/Cloud Center of Excellence teams.

Pros

• Provides contextually relevant information at any level of the organization, with no tagging required
• Gives visibility into cloud resource costs by utilized, idle, or unallocated, at hourly granularity
• Surfaces savings recommendations across workloads and the data justification behind them, including rightsizing
• Performs root cost analysis down to the resource level, with the potential to tie to cloud events and deployment changes when using Harness Continuous Delivery Platform
• Has anomaly detection, budgeting, and forecasting features that help teams avoid or head off surprises in cloud spend

Cons

• May necessitate cultural change within an organization with regards to responsibility for cloud costs to get the full benefits of the product
• New system may require training and some migration effort

Tool #2: AWS Cost Explorer

Each of the public cloud providers has their built-in console for you to see your costs at a high level. AWS Cost Explorer is the built-in tool that Amazon Web Services provides to help you explore your costs. It’s great for starting out with AWS cost optimization and at a small scale, but teams often struggle to use this as the single source of truth as they get more sophisticated.

This tool is primarily useful for finance teams who need a high-level view of their costs and opportunities to save money across their whole cloud infrastructure.

Pros

• Good at small scale, when you have a simple cost structure and few teams
• Gives a high-level view of where costs are coming from
• Provides recommendations for how you can save based on your usage
• Allows you to set budgeting alerts
• No additional cost for AWS customers

Cons

• Requires good tag hygiene to get granular cost visibility
• Can’t see idle or unallocated resource costs
• Can’t see any costs outside of AWS, including hybrid cloud and container costs
• Difficult to rely on exclusively as the organization scales, even for high-level finance
• Not built for you to be proactive, only to see cost reports after the fact (with some ability to create warnings)

Tool #3: Google Cloud Platform Billing

Each of the public cloud providers has their built-in console for you to see your costs at a high level. GCP Billing is the built-in tool that Google Cloud Platform provides to help you understand your GCP cloud bill. It’s great for starting out and at a small scale, but teams often struggle to use this as the single source of truth as it doesn’t provide the necessary level of granularity.

This tool is primarily useful for finance teams who need a high-level view of their costs and opportunities to save money across their whole cloud infrastructure.

Pros

• Good at small scale, when you have a simple cost structure and few teams
• Gives a high-level view of where costs are coming from
• Provides recommendations for how you can save based on your usage
• Allows you to set budgeting alerts and throttle GCP consumption
• No additional cost for GCP customers

Cons

• Requires good tag hygiene to get granular cost visibility
• Can’t see idle or unallocated resource costs
• Can’t see any costs outside of GCP, including hybrid cloud and container costs
• Difficult to rely on exclusively as the organization scales, even for high-level finance
• Allows for some proactivity in managing costs, but in practice it’s hard to use the provided features due to the differing needs of finance and engineering teams

Tool #4: Azure Cost Management + Billing

Each of the public cloud providers has their built-in console for you to see your costs at a high level. Azure Cost Management + Billing is the built-in tool that Microsoft Azure provides to help you understand your Azure cloud bill. Teams can get a high-level view into their cloud spending on Azure, and with some nifty integrations, can do some more.

This tool is primarily useful for finance teams who need a high-level view of their costs and opportunities to save money across their whole cloud infrastructure.

Pros

• Best at small scale, when you have a simple cost structure and few teams
• Integration into PowerBI and AWS (through Cloudyn) allows for better reporting and dashboards
• Provides recommendations for how you can save based on your usage
• Allows you to set budgeting alerts
• No additional cost for Azure customers

Cons

• Requires good tag hygiene to get granular cost visibility
• Can’t see idle or unallocated resource costs
• Difficult to see any costs outside of Azure, including multi-cloud and cluster costs
• Difficult to rely on exclusively as the organization scales, even for high-level finance and with PowerBI integration
• Not built for you to be proactive, only to see cost reports after the fact (with the ability to set warnings)

Tool #5: IBM Cloudability

IBM Cloudability is a cloud cost management tool that focuses on helping customers get visibility into their spend and then manage and optimize it. Originally known as Cloudability, the product became part of IBM's portfolio through its acquisition of Apptio in 2023 and is now offered as part of IBM's broader FinOps Suite alongside Kubecost and IBM Turbonomic.
