Navigating AWS costs can be as complex as building the infrastructure itself. There are many ways to build a cloud architecture, and most are not cost-optimized. Costs can rise quickly if not carefully managed. This article explores various strategies for cost management and optimization on AWS, helping you optimize your bill while leveraging the platform's full potential.
Use Spot Instances
Amazon EC2 Spot Instances are an alternative purchase option, allowing you to buy AWS's unused capacity at prices up to 90% lower than On-Demand. However, AWS can terminate these instances with a two-minute notice, making them unsuitable for workloads that cannot tolerate interruptions.
Spot Instances are great for fault-tolerant applications, such as data analysis, batch jobs, and background processing. To maximize their use, spread your instances across multiple pools and set a maximum price close to On-Demand.
Utilize Reserved Instances
Reserved Instances (RIs) offer significant savings for predictable workloads, with discounts up to 72% compared to On-Demand. RIs are best for stable, predictable production environments.
Before purchasing RIs, analyze your usage to avoid over-provisioning. Consider Convertible RIs for additional flexibility and use RIs to cover your baseline, supplementing with On-Demand or Spot Instances for demand peaks.
Take Advantage of AWS Free Tier
The AWS Free Tier is ideal for new users, startups, and developers looking to experiment and learn. It includes over 60 services, divided into "Always Free," "12 Months Free," and "Short Term Trials."
The Free Tier allows you to gain practical experience without spending money, making it great for trying new ideas and learning about AWS services. However, exceeding Free Tier limits will incur standard charges.
Monitor Usage and Estimate Costs
