The company needs to run its marketing and order-processing applications on different instance types with varying CPU, memory, storage, and networking. Which AWS service provides that capability?

Amazon EC2 (Elastic Compute Cloud) provides resizable compute capacity in the cloud, allowing users to choose from a wide variety of instance types. These instance types are optimized for different use cases and offer varying combinations of CPU, memory, storage, and networking capacity. This flexibility enables a company to select specific instance types that best suit the distinct requirements of its marketing and order-processing applications, such as compute-optimized instances for processing-intensive tasks or memory-optimized instances for large datasets. AWS Lambda is a serverless compute service, not designed for persistent application hosting with specific instance types. Amazon Cognito provides identity management, and Amazon Athena is a query service for S3 data.
