Amazon EC2 instance types
General Purpose
Compute Optimized
Memory Optimized
Accelerated Computing
Storage Optimized
This EC2 instance type provides a balance of compute, memory, and networking resources. You can use them for a variety of workloads.
General Purpose
This EC2 instance type is ideal for compute-bound applications that benefit from high-performance processors
Compute Optimized
This EC2 instance type is designed to deliver fast performance for workloads that process large datasets in memory
Memory Optimized
This EC2 instance type uses hardware accelerators, or coprocessors, to perform some functions more efficiently than is possible in software running on CPU
Accelerated computing
A flexible pricing model offering significant savings over On-Demand pricing, in exchange for a commitment to a consistent amount of usage (in $/hour) for a 1 or 3-year term
Savings Plan
EC2 Reserved instance commitment term
1 or 3-year term
Pricing model ideal for short-term, irregular workloads that cannot be interrupted
On-Demand
This pricing allows you to pay for compute capacity by the hour or second with no long-term commitment
