EC2 Instance Types – General Purpose

Great for a diversity of workloads such as web servers or code repositories. Balanced

t2.micro instance type

General purpose

EC2 Instance Types – Compute Optimized

Great for compute-intensive tasks that require high performance

processors:

• Batch processing workloads

• Media transcoding

• High performance web servers

• High performance computing (HPC)

• Scientific modeling & machine learning

• Dedicated gaming servers

EC2 Instance Types – Memory Optimized

Fast performance for workloads that process large data sets in memory

Use cases:

• High performance, relational/non-relational databases

• Distributed web scale cache stores

• In-memory databases optimized for BI (business intelligence)

• Applications performing real-time processing of big unstructured data

EC2 Instance Types – Storage Optimized

Great for storage-intensive tasks that require high, sequential read and write

access to large data sets on local storage

Use cases:

• High frequency online transaction processing (OLTP) systems

• Relational & NoSQL databases

• Cache for in-memory databases (for example, Redis)

• Data warehousing applications

• Distributed file systems
