Performance characteristics of EC2 instance types
The performance characteristics of EC2 instance types can be summarized as follows:
General Purpose Instances:
- Provide a balance of compute, memory, and networking resources.
- Suitable for applications that require these resources in equal proportions, such as web servers and code repositories.
- Examples include the T, M, and A instance families.
Burstable Performance Instances:
- Also known as the T instance family.
- Provide a baseline CPU performance with the ability to burst above the baseline when needed.
- Suitable for workloads that don't require sustained high CPU performance.
Compute Optimized Instances:
- Designed for compute-intensive applications that benefit from high-performance processors.
- Ideal for batch processing, media transcoding, high-performance web servers, high-performance computing (HPC), and machine learning inference.
- Examples include the C and Hpc instance families.
Memory Optimized Instances:
- Designed to deliver fast performance for workloads that process large data sets in memory.
- Suitable for in-memory databases, real-time big data analytics, and other memory-intensive applications.
- Examples include the R, X, and U instance families.
Storage Optimized Instances:
- Include persistent storage to write and retrieve information from databases at high speed.
- Suitable for applications that require high, sustained I/O performance, such as databases and data warehouses.
- Examples include the I, D, and Im instance families.
Accelerated Computing Instances:
- Provide hardware accelerators, such as GPUs, to support graphics-intensive or analytical workloads.
- Ideal for machine learning, scientific computing, and 3D application rendering.
- Examples include the P and G instance families.
