AWS Pricing - Quick Overview

You can read more about the AWS Free Tier.

AWS has 3 pricing fundamentals, following the pricing model:

• Compute: Pay for compute time
• Storage: Pay for data stored in the Cloud
• Outbound data transfer: Data transfer OUT of the Cloud, data transfer IN is free

AWS Global Infrastructure

AWS Regions

• AWS has Regions all around the world
• Names can be us-east-1, eu-west-3 ...
• A region is a cluster of data centers
• Most AWS services are region-scoped, check the Region Table

How to choose an AWS Region?

• : data never leaves a region without your explicit permission
• : reduced latency
• : new services and new features aren't available in every Region
• : pricing varies region to region and is transparent in the service pricing page

AWS Availability Zones

• Each region has many availability zones(usually 3, min is 3, max is 6). Example:
  • ap-southeast-2a
  • ap-southeast-2b
  • ap-southeast-2c
• Each availability zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity
• They're separate from each other, so that they're isolated from disasters
• They're connected with high bandwidth, ultra-low latency networking

AWS Edge Locations / Points of Presence

• Amazon has Points of Presence (400+ Edge Locations & 10+ Regional Caches) in cities across countries
• Content is delivered to end users with lower latency

  • Identity and Access Management (IAM)
  • Route 53 (DNS service)
  • CloudFront (Content Delivery Network)
