[AWS] EC2 – Instance Types

An Instance Type determines a particular set of features and sizes (hardware components) that decide the level of workload – Compute Power (vCPU), Memory, Storage Options, Network Performance.

Instance Types

General Purpose

  • a balance of compute, memory, and network resources
  • T2, T3: low-cost (baseline level) types that provide burst capability
  • M4, M5, M6, M7: general workloads, balanced

Compute Optimized

  • C4, C5, C6, C7: more capable CPU, for high-performance calculation apps

Memory Optimized

  • X1, X2, R4, R5, R6, R7: optimized memory (fast and large amount) for high-performance database

Storage Optimized

  • D2, D3: Density High Throughput (HDD), for Data Warehouse, MapReduce, HDFS, Network file systems
  • I3: High-speed Random IO (SSD), for No SQL database, data warehouse
  • H1: High Disk Throughput for MapReduce

Accelerated Computing

  • P2, P3: General purpose GPU (Graphics Processing Unit), for machine learning
  • F1: FPGA (Field Programmable Gate Arrays), computationally intensive
  • G3, G4, G5: Cost-effective GPUs, for video encoding, 3D rendering

HPC Optimized

  • Offers the best price performance for running HPC (High Performance Computing) workloads
  • Hpc6id: Intel Xeon + EFA (Elastic Fabric Adapter)
  • Hpc6a: AMD EPYC + EFA

Memorize the Mnemonic “FIGHT DR MC PX – AZ

  • F (FPGA), I (IOPS), G (Graphics), H (High Throughput), T (Tight – cheap general)
  • D (Density High Throughput), R (RAM – memory)
  • M (Main or Medium – general), C (Compute)
  • P (Pic – graphics), X (Extreme Memory)
  • A (Arm-based), Z (Extreme memory and CPU)

Graviton Processors

AWS Graviton processors deliver the best price performance for your workloads running in EC2 instances.

AWS Graviton – Amazon Web Services

  • Supports many Linux OSs:
    • Amazon Linux 2, Red Hat Enterprise Linux, SUSE, and Ubuntu
    • It does not support Windows.
  • Gravition processors can be used with different types of instances (M6g, C7g, R6g, Im4gn, or G5g)
