EC2 Pricing: What AWS Won’t Tell You
Blog post from Cast AI
AWS offers a wide range of Amazon EC2 instance types, each designed for specific use cases and workloads. The service provides almost 400 different instances across various processors, storage options, networking, operating systems, and purchase models, catering to diverse needs in 24 regions and 77 availability zones globally. To choose the right VM type for a job, it's essential to consider factors such as CPU to memory ratio, instance size, storage throughput, and network capacity. EC2 pricing models include On-Demand, Reserved Instances, Savings Plans, Spot Instances, and Dedicated Hosts, each with its pros and cons. By selecting the appropriate instance type, scaling resources, and leveraging features like spot instances, users can optimize their cloud bill and achieve better performance for their workloads. Additionally, automation tools can help manage EC2 pricing by automatically selecting the best instance types and handling interruptions from spot instances.
