As a technology startup Chief Technology Officer (CTO), you know about Amazon Web Services (AWS) fundamentals. It's the global leader in cloud services, providing a broad set of scalable, flexible, and cost-effective tools that many startups leverage to power their tech stack. However, AWS's vast portfolio hides many lesser-known features that can provide even more value. Let's dive into some of these under-appreciated aspects of AWS.

AWS Savings Plans

AWS Savings Plans is a flexible pricing model that offers significant savings on Amazon Web Services (AWS) usage. It is similar to Reserved Instances (RIs) but provides more flexibility, making it an appealing choice for customers with changing usage patterns.

Savings Plans come in two types: Compute Savings Plans and EC2 Instance Savings Plans.

Compute Savings Plans offer great flexibility and can be used across any AWS region, any AWS compute service (such as AWS Fargate or AWS Lambda), and on instances of any size, family, or region. This is particularly useful for organizations that switch instance types, upgrade instances, or move workloads across regions.

EC2 Instance Savings Plans, on the other hand, apply to a specific instance family within a chosen region. These plans offer higher discounts than Compute Savings Plans and are suitable for steady-state workloads.

Here's why Savings Plans can be beneficial for tech startups:

  1. Cost Savings: Savings Plans can offer significant savings over On-Demand prices, which can be crucial for startups looking to optimize costs. You commit to a consistent amount of usage, measured in dollars per hour, over 1 or 3 years, and in return, you receive a discount on that usage.

  2. Flexibility: Unlike Reserved Instances, Savings Plans allow you to change instance families, sizes, operating systems, tenancies, or AWS Regions without worrying about modifying your reservations. This is invaluable for startups that have changing business needs and usage patterns.

  3. Simplicity: With Savings Plans, AWS takes care of the discount application process. AWS will apply the discounted Savings Plans price when your commitment covers usage. When you exceed the commitment, AWS charges the On-Demand rate. This process simplifies the management of cost optimization and allows startups to focus more on their core business functions.

Understanding how Savings Plans work and effectively using them can result in substantial cost savings for startups, making it a noteworthy feature in the AWS landscape.
