What Are Different EC2 Instance Types?

This article explains Different EC2 Instance Types.

In fact, Amazon Elastic Compute Cloud (Amazon EC2) offers a wide range of instance types, each optimized for different use cases and workloads. Furthermore, these instance types vary in terms of compute power, memory, storage, and networking capabilities. The following list shows some of the most common EC2 instance types along with their general characteristics.

List of Different EC2 Instance Types

  1. General Purpose. The following three instance types are used for general purposes.
    • T2: Burstable performance instances suitable for applications with variable workloads.
    • M4: Balanced compute, memory, and network resources for general-purpose applications.
    • M5: Improved performance over M4 instances with higher compute and memory capacities.
  2. Compute Optimized. Similarly, the following instance types are compute-optimized.
    • C4: High-performance instances optimized for compute-intensive applications.
    • C5: Next-generation compute instances with high CPU performance and memory.
  3. Memory Optimized. likewise, these instance types are memory-optimized.
    • R4: Memory-optimized instances for applications that require high memory capacity.
    • R5: Upgraded version of R4 instances with improved performance and memory.
  4. Accelerated Computing. However, if you have high-performance computing requirements, you can use these types.
    • P3: Instances optimized for machine learning, high-performance computing, and other GPU-intensive workloads.
    • G3: Graphics-intensive instances for applications that require GPU acceleration.
  5. Storage Optimized. In order to execute storage-intensive applications, we have these types.
    • I3: High-performance instances with fast SSD storage for storage-intensive applications and databases.
    • D2: Dense storage instances designed for data warehouses, big data processing, and analytics.
  6. Bare Metal.
    • M5/M5d Bare Metal. Basically, it offers the performance of traditional on-premises servers with the scalability and flexibility of EC2 instances.
  7. High-Performance Computing (HPC). For the purpose of high-performance computing, we have these types.
    • HPC6: High-performance computing instances designed for parallel processing and scientific simulations.
  8. Instances with Local NVMe Storage.
    • C5d: Compute instances with local NVMe storage for applications requiring high-speed local storage.
    • M5d: Memory-optimized instances with local NVMe storage for applications demanding high I/O performance.
  9. Instances with Local HDD Storage.
    • H1: Storage-optimized instances for big data and data-intensive applications.
  10. Instances with High Network Performance:
    • F1: Instances with field-programmable gate arrays (FPGAs) for custom hardware acceleration.
    • X1e: Memory-optimized instances with high-speed networking and large memory.


To summarize, these are just a few examples of EC2 instance types available in AWS. In fact, each instance type has its own pricing model based on factors like compute capacity, memory, storage, and other features. When choosing an instance type, consider your application’s requirements, workload characteristics, and performance needs.
