Finding Cloud Cost Waste

Cloud cost waste often lurks in unexpected places. To manage your cloud spending effectively, you need to understand where your money is going. Let’s dive into specific ways to uncover inefficiencies in your resources.

Resource Usage Assessment

Take a close look at your cloud infrastructure to spot underused resources. Pay attention to these four areas:

Resource Type	Common Issues	How to Assess
Compute	Idle instances, oversized VMs and containers	Check CPU and memory usage metrics
Storage	Unused volumes, outdated snapshots	Use storage analytics and track age of resources
Network	Excessive data transfer, idle load balancers	Review traffic patterns and monitor endpoints
Cloud-specific services	Unused secrets in SecretsManager, unused KMS keys, excessive logging etc	Analyze if any of the services take up big part of your monthly bill

Review historical usage data to predict future needs and adjust your configurations accordingly. Once you've completed this step, focus on identifying the biggest cost contributors to guide your next actions.

Main Cost Factors

Knowing what drives your costs allows you to focus your optimization efforts where they’ll have the most impact. Typically, compute resources take the largest share, followed by storage and data transfer expenses.

• Compute Resources: Keep an eye on instance types and how efficiently they’re being used.
• Storage Solutions: Evaluate how data is stored, including lifecycle policies and storage tiers.
  
• Network Traffic: Examine patterns of data transfer between regions and services.

Cost Reduction Methods

These methods focus on cutting unnecessary expenses by addressing inefficiencies.

Resource Sizing

Optimize resource usage by analyzing consumption patterns to avoid waste. Key areas to focus on include:

• Compute: Adjust instance sizes to match actual workload. Using auto-scaling and leverage elasticity whenever you can.
• Databases: Choose instance classes that align with your demand.
• Storage: Move rarely accessed data to lower-cost storage tiers and get rid of unused storage.

Track resource usage over a couple of weeks to understand both typical and peak demands. This ensures adjustments are accurate and prevents overspending.

Instance Purchase Options

For steady workloads, consider Reserved Instances or Savings Plans to lock in lower rates. For tasks like batch processing, testing, or data analysis, leverage spot instances to save on costs.

Serverless Alternatives

Evaluate which platform-specific serverless offering can help with your workloads. Quite often, using those can ensure elasticity and bring pay-per-use model - which can end up in lower costs. For example, check if using serverless compute and queueing service like AWS Lambda and SQS can be cheaper in your case than running ECS Containers and something like RabbitMQ.

Auto-Scaling Setup

Set up auto-scaling with well-defined metrics, such as CPU usage, memory, request count, or network I/O. Key steps include:

• Establish triggers for scaling up or down, with cooldown periods to avoid frequent adjustments.
• Regularly review and fine-tune your auto-scaling policies using built-in monitoring tools.
• Test auto-scaling configurations in a staging environment to ensure smooth production performance.
