Q: When should I use AWS Compute Optimizer and when should I use AWS Cost Explorer?
You should use AWS Cost Explorer if you want to identify under-utilized EC2 instances that may be downsized on an instance by instance basis within the same instance family, and you want to understand the potential impact on your AWS bill by taking into account your RIs and Savings Plans. Cost Explorer offers recommendations for all commercial regions (outside of China) and supports the A, T, M, C, R, X, Z, I, D, H instance families.
You should use AWS Compute Optimizer if you want to look at instance type recommendations beyond downsizing within an instance family. You can use AWS Compute Optimizer to get downsizing recommendations within or across instance families, upsizing recommendations to remove performance bottlenecks, and recommendations for EC2 instances that are parts of an Auto Scaling group. AWS Compute Optimizer provides you additional capabilities to enhance recommendation quality and the user experience, such as using machine learning to identify workload types and automatically choose workload-specific recommendation methodology for them. You should also use AWS Compute Optimizer if you want to understand the performance risks and how your workload would perform on various EC2 instance options to evaluate the price-performance trade-off for your workloads. AWS Compute Optimizer is available in US East (N. Virginia), US East (Ohio), US West (Oregon), EU (Ireland), and South America (Sao Paulo), and supports the M, C, R, T and X instance families.
