What is Regions?

1. AWS has Regions all round the world

2. Name can be us-east, eu-west-3

3. A Region is a cluster of data centers

4. Most AWS  services are region-scoped

 

How to choose an AWS Region?

1. Compliance with data governance  and legal requirements : data never leaves a region without your explicit
    permission

2. Proximity to customers: reduced latency

3. Available service within a Region: new  services and new features aren't available in every region

4. Pricing: pricing varies region to region and  is transparent in the service pricing page

 

Waht is Availability Zones?

1. Each region has many availability zones

    (usually 3, min is 2, max is 6) 

    - ap-southeast-2a

    - ap-southeast-2b

    - ap-southeast-2c

2. Each availablity zone (AZ) is one or more discrete data centers with redundant power, networking, and connectiviy

3. They're separate from each other, so that they're isolated from disasters

4. They're connected with high bandwidth, ultra-low latency networking

 

AWS service scope 구분.

1. AWS has Global Service

    - Identity and Access Management (IAM)

    - Route 53 (DNS Service)

    - CloudFront (Content Delivery Network)

    - Elastic Beanstalk (Platform as a Service)

    - Lambda (Function as a Service)

    - Rekognition (Software as a Service)
