Amazon Elastic Compute Cloud (Amazon EC2)

Amazon EC2 provides pay-as-you-go pricing and a broad selection of hardware and software that's available via the AWS Marketplace by using Amazon Machine Images (AMIs)

  • Pay only for what you use
  • Resizable compute capacity
  • Complete control of your computing resources
  • Reduced time required to obtain and boot new server instances

Template for:

  • Storage volumes
  • Launch permissions
  • A block device mapping

Examples

  • Application server
  • Web server
  • Database server
  • Game server
  • Mail server
  • Media server
  • Catalog server
  • File server

Virtual Machines vs. Physical Servers

Amazon EC2 can solve some problems that are more difficult with an on-premises server.

When using disposable resources:

Benefits of Amazon EC2

  • Elasticity
  • Control
  • Flexibility
  • Integrated
  • Reliable
  • Secure
  • Inexpensive
  • Simple

Amazon EC2 Instance Families and Names

Choosing the correct type is very important for efficient use of your instances and cost reduction.

General Purpose

  • Suitable for a broad range of workloads
  • Balances compute, memory, and networking resources
  • Use cases
    • Small databases and midsize databases
    • Low-traffic websites and web applications

Compute Optimized

  • Offers high-performance processors
  • Ideal for compute-intensive applications and batch processing workloads
  • Use cases
    • Video encoding
    • High-performance web servers

Memory Optimized

  • Delivers fast performance for memory-intensve workloads
  • Well suited for high-performance databases
  • Use cases
    • Distributed memory caches
    • High-performance databases

Storage Optimized

  • Offers low latency and high input/output operations per seconds (IOPS)
  • Suitable for workloads such as distributed file systems and data warehousing applications
  • Use cases
    • Data warehousing
    • Log or data processing applications

Accelerated Computing

  • Uses hardware accelerators to expedite data processing
  • Ideal for application streaming and graphics workloads
  • Use cases
    • 3D visualizations
    • Machine learning

Instance Pricing Options

On-Demand

  • No upfront costs or minimum contracts
  • Ideal for short-term, irregular workloads

Spot

  • Ideal for workloads with flexible start and end times
  • Offers savings over On-Demand prices
  • Can withstand interruptions

Reserved

  • Provides a billing discount over On-Demand pricing
  • Requires a 1-year or 3-year term commitment

Compute Savings Plan

  • Offers up to 72% savings over On-Demand costs for a consistent amount of compute usage
  • Requires a 1-year or 3-year term commitment

Dedicated Instance

  • An EC2 instance that runs in a VPC on hardware for a single customer
  • Higher cost compared to standard Amazon EC2 instances

Dedicated Host

  • A physical server with EC2 instance capacity for a single customer
  • Most expensive Amazon EC2 option
