AWS Cloud EC2 Instance Types

Here are some common EC2 instance families and types:

  1. General Purpose Instances:

    • T3 Series: Burstable instances suitable for applications with variable workloads.
    • T4g Series: Powered by AWS Graviton2 processors, offering a good balance of performance and cost-effectiveness.
    • T3a Series: Similar to T3 instances but powered by AMD EPYC processors.
  2. Compute Optimized Instances:

    • C6g Series: Compute-optimized instances powered by AWS Graviton2 processors.
    • C5 Series: Compute-optimized instances suitable for compute-intensive workloads.
  3. Memory Optimized Instances:

    • R6g Series: Memory-optimized instances powered by AWS Graviton2 processors.
    • R5 Series: Memory-optimized instances suitable for memory-intensive applications.
  4. Storage Optimized Instances:

    • I3 Series: Storage-optimized instances with high-speed, NVMe-based SSD storage.
    • I3en Series: I3 instances with additional storage capacity and higher network bandwidth.
    • D3 Series: Dense storage instances optimized for data-intensive workloads.
    • H1 Series: HDD-backed storage instances for high-throughput, big data workloads.
  5. Accelerated Computing Instances:

    • P4, P3 Series: GPU instances suitable for high-performance computing, deep learning, and machine learning.
    • F1 Series: Instances with field-programmable gate arrays (FPGAs) for customizable hardware acceleration.
    • Inf1 Series: Instances with AWS Inferentia chips for high-performance inference in machine learning models.
  6. Bare Metal Instances:

    • I3 Metal, M5 Metal, etc.: These instances provide direct access to the underlying hardware without virtualization, offering high performance and flexibility.
  7. Free Tier Instances:

    • t2.micro: Part of the AWS Free Tier, allowing users to run a micro instance for free each month for 12 months.
  8. Graviton2-Based Instances:

    • M6g Series: General-purpose instances powered by AWS Graviton2 processors.
    • C6g, R6g Series: Compute and memory-optimized instances powered by Graviton2.
