Top 6 Cloud Cost Management Tools You’ll Need to Thrive in 2023

Cloud cost management is tricky for many companies, especially when using cloud-native technologies such as microservices, containers, and Kubernetes. Cloud bills tend to bury the information behind rows of text and tables, making it challenging to discover where your money is really going. 

cloud cost management

That’s why so many organizations are now deploying cloud cost management platforms that let them identify which products and features drive their cloud spend or which customers are causing them to spend more. 

Equipped with this type of cost intelligence, your team can make more informed engineering and business decisions in the cloud.

To help you out, we prepared a guide to cloud cost management. Let’s dive in and explore what cloud cost management is all about, why it’s worth your time, and which tools you should consider. 

What is cloud cost management?

Cloud cost management aims to minimize costs associated with cloud services while delivering the same level of performance. The term refers to monitoring, measuring, and controlling cloud costs to ensure that you are maximizing your investment in public cloud services. 

Traditionally, cloud cost management has focused on waste reduction efforts – for example, eliminating underutilized or forgotten resources and optimizing purchasing decisions (reserved instances and savings plans). 

But as companies evolve to adopt next-generation cloud services, cloud cost management focuses on architectural optimization. Teams can build products utilizing cloud services that tightly align with cost and customer utilization with the right architecture.

Added to this is the benefit of automated cloud cost optimization that helps to address.

Benefits of cloud cost management

Managing cloud costs brings your team a host of benefits:

  • You get more accurate at forecasting, planning, and budgeting your cloud spend.
  • Greater cost visibility empowers your engineers to see the impact of their work on your budget.
  • Cloud cost management allows you to discover areas of your solutions that could use rearchitecting for increased profitability.
  • Make informed decisions about adjusting your pricing structure and decommissioning resources.
  • Benefit from load balancing, autoscaling, capacity reservation, volume discounts, saving programs, and spot instances.  
  • Identify the best services to use for each application.

Building a cloud cost management strategy

Nearly every company out there has some type of governance in place, with security and compliance as its most important. Why not add a cloud cost management strategy to your governance plan? That way, you will gain more control over your cloud infrastructure and the costs it incurs.

This type of strategy can include the following points:

  • Provide a uniform and succinct labeling approach that everyone can use.
  • Instructions for setting up monitoring and alerting tools.
  • Create a method for evaluating and optimizing costs on an ongoing basis.

Do cloud providers offer cost management?

Yes, the three major cloud service providers – AWS, Google Cloud, and Microsoft Azure – provide a range of built-in cost management and reporting tools to help you make sense of your cloud bill. However, native tools often deliver cost data with a delay, sometimes even up to 48 hours. And in the cloud world, this could translate into thousands of dollars lost of a job running without your knowledge.

Why is cloud cost management so difficult?

One of the most significant problems in cloud cost management is the lack of visibility into spending behaviors of the engineering team. The other challenge is closely related – it’s about getting engineers to become more cost-aware and include cost into their decision-making processes. Some businesses may discover hidden expenses because they lack the necessary tools to calculate cloud spending. Furthermore, cloud customers may misinterpret cost statistics and end up paying more than necessary.

What are the cloud cost models?

Given the irregular nature of supply and demand in cloud computing, cloud cost models tend to be dynamic. Depending on the circumstances, you can choose an auction-based, time-based, or cost-based models. And consider three types of cloud pricing strategies: value-based pricing, fact-based pricing, and market-based pricing.

What is cloud cost analysis?

A cloud cost analysis provides insights into where your cloud budget is going and whether teams are using the provsioned resources efficiently. Producing a meaningful cloud cost analysis may be difficult when the cost of resources used by the same workloads, departments, teams or projects.

What are the best practices for cloud cost management?

1. Begin by taking a snapshot of your cloud costs at a specified period in time (for example, at the end of the month).
2. Next, determine where these charges originate. Assign your cloud spending to teams or departments to identify the primary contributors.
3. Examine your consumption and growth patterns to understand whether these charges are reasonable.
4. Assess your infrastructure to check if there are any abandoned projects, shadow IT initiatives, or underutilized virtual machines.
5. Compare your consumption to resource capacity to determine overprovisioning or underutilization.
6. Develop an optimization strategy based on all of your findings. Get the engineering team’s approval to guarantee that your strategy provides the needed degree of performance.
7. Consider the future. Begin planning how you will obtain additional capacity or delete resources you will no longer require.
8. Estimate your expenses, reserve capacity ahead of time, and negotiate volume savings with the provider.
