Lecture Notes

Compute on AWS

Amazon Elastic Compute Cloud (EC2)

  • Amazon EC2 provides resizable compute capacity in the cloud, similar to a virtual or physical server.
  • It supports workloads such as web hosting, applications, databases, authentication services, and other general-purpose server tasks.

Instance Types

  • EC2 configurations are defined by instance types, not custom hardware.
  • Each type specifies:
    • CPU (Intel, AMD, ARM – Graviton 1/2/3) / GPU
    • Memory
    • Network
    • Storage

Instance Type Categories:

  • General Purpose: T3, T4g, M5, M6i (balanced compute, memory, networking)
  • Compute Optimized: C5, C6i, C7g (high-performance processors)
  • Memory Optimized: R5, R6i, X2 (fast performance for memory-intensive workloads)
  • Storage Optimized: I3, D2, H1 (high sequential read/write to local storage)
  • Accelerated Computing: P4, G5, Inf1 (GPU/FPGA for ML, graphics)

Amazon Machine Images (AMI)

  • AMI (Amazon Machine Image) is a template that defines the software configuration of an instance, including OS, apps, and settings.
  • Types of AMIs:
    • Provided by AWS (Amazon Linux, Windows, Ubuntu, etc.)
    • AWS Marketplace AMIs
    • Custom AMIs created by users

Benefits of Custom AMIs

  • Faster instance launch and setup
  • Simplified backup and restore
  • Consistent environment across multiple instances

AMI Components:

  • Root volume template (OS and applications)
  • Launch permissions
  • Block device mapping
