General Purpose
General purpose instances provide a balance of compute, memory and networking resources, and can be used for a variety of diverse workloads. These instances are ideal for applications that use these resources in equal proportions such as web servers and code repositories.
Compute Optimized
Compute Optimized instances are ideal for compute bound applications that benefit from high performance processors.
Memory Optimized
Memory optimized instances are designed to deliver fast performance for workloads that process large data sets in memory.
Accelerated Computing
Accelerated computing instances use hardware accelerators, or co-processors, to perform functions, such as floating point number calculations, graphics processing, or data pattern matching, more efficiently than is possible in software running on CPUs.
Storage Optimized
Storage optimized instances are designed for workloads that require high, sequential read and write access to very large data sets on local storage. They are optimized to deliver tens of thousands of low-latency, random I/O operations per second (IOPS) to applications.
Instance Features
Amazon EC2 instances provide a number of additional features to help you deploy, manage, and scale your applications.
