Which EC2 instance type is memory-optimized?

The r5.large instance type is classified as a memory-optimized instance in the Amazon EC2 family. Memory-optimized instances are specifically designed to deliver fast performance for workloads that require high memory processing, such as databases, in-memory caches, and real-time big data analytics.

The r5 instances offer a large amount of RAM relative to the CPU, which makes them ideal for applications that need to manage large datasets in memory to provide fast response times. The r5.large instance offers a balanced combination of compute, memory, and storage resources, supporting workloads that require more memory compared to compute power.

This makes r5 instances particularly well-suited for tasks such as high-performance databases, data mining, and processing large in-memory data sets. Such features highlight why the r5.large is categorized as memory-optimized, emphasizing the need for applications that benefit from higher memory availability.
