Everyone wants to pay less for the same service. If you will commit then you can access savings from AWS. There are several varieties of offers available but today we are going to look at using reserved instances to manage your monthly AWS spend.
Reserved Instances are a billing option offered by AWS that enables you to reserve computing capacity for a specified term. By committing to a contract with AWS, you receive a substantial discount compared to On-Demand pricing. Reserved instances are available in three payment options:
Reserved Instances come in various flavours:
Analyze Your Usage Patterns: Before diving into this, analyze your historical usage patterns. This will help you identify which instance types and workloads are consistent and can benefit from reservation.
Choose the Right reserved instance Type: Based on your usage analysis, choose between Standard, Convertible, or Scheduled. Convertible offer greater flexibility but at a slightly reduced discount.
Strategize for reserved instance Size Flexibility: Consider opting for a size-flexible reserved instance, which allows you to match instances of varying sizes within the same instance family. This is especially useful when your workload's exact size requirements might change.
Blend reserved instances with On-Demand Instances: Don't lock yourself into an all-reserved instance strategy. Use reserved instance for steady workloads and On-Demand instances for dynamic or unpredictable workloads.
Monitor and Adjust: Cloud needs change over time. Regularly review your reserved instance usage and adjust your reservations as needed. AWS offers tools like AWS Cost Explorer and AWS Trusted Advisor to help you monitor your reserved instance coverage.
Leverage Savings Plans: Savings Plans offer similar savings to reserved instance but with more flexibility. They cover a broader range of services and instance families, making them a great choice for organizations with diverse workloads.
Stay Up to Date: AWS frequently updates its offerings and pricing models. Stay informed about changes and adapt your cost optimization strategy accordingly.
Use Third-Party Tools: Numerous third-party tools and services are available to help you analyze your AWS usage, recommend reserved instance purchases, and manage your cloud costs effectively.
