Summary

In this chapter, you have learned about designing cost-optimized architectures, which forms a critical 20% of the SAA-C03 exam. You began by exploring techniques for designing cost-effective storage solutions on AWS. You gained an understanding of the pricing models and cost characteristics of various AWS storage services, such as Amazon S3, Amazon Glacier, Amazon EFS, and Amazon EBS. You then dove into strategies for leveraging storage access patterns to minimize costs, including optimizing for batch uploads, implementing storage tiering, and managing data lifecycles.

Next, you shifted your focus to cost-optimized compute solutions. You reviewed the different compute service pricing models offered by AWS, including On-Demand, Reserved Instances, and Spot Instances. You learned how to select the appropriate compute service and instance type based on the specific requirements of your workloads, as well as techniques for optimizing compute utilization through autoscaling and...
