Guide to Cloud Cost Management

The Ultimate Guide to Cloud Cost Management

Navigating the maze of cloud cost management can be a daunting task. As organizations increasingly rely on cloud infrastructure for their operations, it’s crucial to have a cloud cost management strategy. This guide breaks down the essentials of managing and optimizing your cloud costs.

What is Cloud Cost Management?

Cloud cost management controls and optimizes the costs associated with cloud computing resources. It involves various strategies and tools designed to provide complete visibility into cloud spend. This enables better cost allocation, cost savings, and budgeting.

Why is Cloud Cost Management Essential?

The cloud offers unprecedented flexibility, but you can incur unnecessary expenses and waste resources without proper management. Cloud cost management provides the oversight needed to use cloud resources efficiently, thus minimizing costs and maximizing the business value of your cloud investments.

How to do Cost Optimization in the Cloud?

Cost optimization in the cloud involves a set of practices designed to help organizations minimize cloud spending while maximizing the value of cloud usage.

Steps for Cost Optimization

  1. Delete Unused Resources: Tools like AWS Trusted Advisor, Azure Advisor, and Google Cloud Recommender can help identify unused instances, storage disks, and IP addresses, thus reducing cloud waste.
  2. Rightsize resources: Rightsizing is optimizing cloud resources to ensure that resources are neither over-provisioned nor under-provisioned, leading to cost savings and improved performance. The same tools mentioned above offer rightsizing recommendations, too.
  3. Utilize Reserved Instances and Savings Plans: Cloud providers offer volume discounts for reserving instances and other resources that can be used to achieve significant savings. Cloud cost management tools also help identify these cloud spend reduction opportunities.
  4. Use cloud best practices: Each cloud provider has best practices that should be followed when deploying cloud infrastructure, as they often help you reduce cloud spend. Examples of these best practices include using the latest generation instance types and storage types, setting retention policies for storage buckets and cloud logs, and utilizing existing software licenses vs. purchasing new ones.
  5. Use automated scheduling: Certain cloud services support start/stop operations. This feature can be used to reduce cloud waste by only running the required services during business hours. For example, you might be able to stop development and staging environments during nights and weekends, thus reducing your cloud spend.
  6. Automate Cost Monitoring: Real-time cost monitoring against a cloud budget enables immediate response to cost anomalies and overruns.
  7. Ensure future compliance: By implementing tools such as Infracost, you ensure that your FinOps and Cloud Cost Management are automated directly in engineering workflows. This ensures that cloud best practices are followed automatically, cloud cost budget breaches are caught before money is spent, and all resources are tagged correctly.

Different Cloud Costing Model Strategies

To better action cloud cost management strategies, it is helpful to understand the formula of cloud costs. That formula is Cloud Costs = Usage x Unit Price

Looking at the Unit Price part of this formula, it’s helpful to understand the different pricing mechanisms of cloud providers. Three of the most common ways resources are charged for are:

  1. Pay-as-You-Go: This is the most flexible model, where you pay for cloud resources as you use them.
  2. Reserved Instances and Savings Plans: This involves pre-purchasing cloud resources at a discounted rate, often requiring a long-term commitment.
  3. Spot Instances: Suitable for workloads with flexible start and end times, Spot Instances allow you to use spare capacity at a fraction of the regular price.

Is Cloud Cost Management the Same as Cloud Cost Optimization?

Cost Management Versus Cloud Cost Optimization

These terms are often used interchangeably, but they are different. Cloud cost management is a broader term that encompasses tracking, analyzing, and controlling cloud costs. Cloud cost optimization is a subset focused exclusively on reducing and controlling those costs. This could be achieved by optimizing cloud spend (by changing cloud infrastructure) or the rate paid for those resources.

What is a Cost Management Tool?

Cloud cost management tools provide analytics on your bills, insights, and recommendations to manage cloud costs effectively. The features range widely, but generally, they can detect cost anomalies, help allocate costs to your cost center, provide the basis to calculate your unit cost, and view your cloud resource costs.

Examples include tools from cloud providers such as AWS Cost Explorer, Google Cloud’s cost management tools, Azure Cost Management. and third-party solutions. These tools offer insights into cloud costs and your billing data and facilitate cost allocation, providing a complete cloud cost management solution.

A newer category of tools has started to emerge, which is trying to shift cloud costs left (meaning earlier in the engineering workflow rather than later). One of these tools is Infracost, which shows engineers how their code changes will impact cloud costs. It also checks the code to ensure the right tags are applied, and best practices are being followed before the code is shipped.

Why Is Cloud Cost Management So Difficult?

Complexity of Cloud Services

The cloud offers various services, each with its pricing structure, making it challenging to keep track of expenses.

Lack of Visibility

Organizations often need more cost visibility into their cloud usage, making it difficult to allocate costs accurately. To enable deeper visibility, companies need to tag their cloud resources with the categories that give them the required visibility, such as who owns a resource (or cost center), what application it belongs to, and what environment it is in (e.g., production, staging, development). Tagging is hard to do well at scale on multi-cloud environments as it requires someone to review all cloud resources and add the necessary metadata for the resources. Furthermore, resources are regularly being changed, which might require updating the metadata.

Rapidly Changing Environment

Cloud environments evolve quickly, making predicting future costs and associated risks hard.

How to Monitor Cloud Spending?

Monitoring cloud spending involves continuously tracking and comparing expenses against your budget.

Tools for Monitoring Cloud Spend

  • AWS Cost Explorer
  • Google Cloud Platform’s Cost Tools
  • Azure Cost Management

How to Manage Cloud Costs?

Managing cloud costs involves proactive planning and ongoing scrutiny. This involves setting up a cloud budget, regularly reviewing bills, and analyzing billing data to identify cost-saving opportunities.

The Benefits of Cloud Cost Management

  1. Cost Transparency: Full visibility into your cloud spending.
  2. Waste Reduction: Identify and eliminate idle resources.
  3. Maximize Savings: Optimizing purchasing decisions and using cloud resource costs to your advantage.
  4. Efficient Usage: Allocate resources where they generate the most value based on usage data and business metrics.

Improve Visibility, Allocation, and Efficiency of Cloud Spend at Scale

Visibility, Allocation, and Efficiency of Cloud Spend

A well-implemented cloud cost management strategy offers benefits beyond mere cost savings. By focusing on cost and customer utilization, businesses can allocate resources more efficiently, achieving significant savings in the long run.

Complete Cost Visibility

Complete visibility into your cloud costs enables you to identify areas for potential savings, optimize costs, and improve the efficiency of cloud spending at an enterprise scale.
