  • Facilitates portability of data, apps, and services and more choices for deployment models

Q

AWS Global Infrastructure:

A

Region
-physical location containing two or more Availability Zones (AZ)

Availability Zone (AZ)

- composed of one or more datacenters 
- each AZ is designed as independent failure zone

Deploying services globally

- Launch virtual servers (instances) and databases
- If an AZ or region fails, you have resilience and a failover to deploy to a different AZ or region

Local Zones

- place compute, storage, database, and other select AWS services closer to end-users
- Extension of an AWS region where you can run your latency sensitive applications

Edge Locations

- Content Delivery Network (CDN) endpoints for CloudFront
- There are many more Edge locations than regions

Regional Edge Caches

- sit between your CloudFront Origin servers and Edge Locations
- More bandwidth

Q

API Analogy

A
  • Client hires a builder
  • ->The builder then provides a set of standard options
  • —>The builder then hires Electricians, Carpenters and other construction trades
  • —–>The builder then gives instructions to the workers in the language they understand (the client would not be able to provide this level of language and understanding of how to complete the task)

Q

List 3 ways (tools) to launch Cloud Services

A

AWS Management Console
-A web-based console accessed through a standard web browser

Command Line

  • Command can launch a virtual server on AWS
  • Command can list the contents of a storage container (bucket) on S3

Software Development Kit

  • Interacting programmatically directly with the API
  • developer writes code in an integrated development environment (IDE)
  • The code leverages the SDK to work with cloud services

Q

What is the difference between AWS Public and AWS Private Services

A

Public Services

  • Have public IP addresses/endpoints - connect directly via a public address
  • Example: Amazon DynamoDB, Amazon CloudFront

Private services

  • Can have public IP addresses but exist within the Virtual Private Cloud (VPC)
  • You can create your own private resources (then decide if you want them to be public or private IP address)

**Can connect from a private space to a public space via an internet gateway

17
Q

What are the fundamentals of Pricing?

A

Compute - CPU/RAM and duration

Storage - quantity of data stored or allocated

Outbound data transfer - data leaving an AWS Region

18
Q

Which policy describes the prohibited uses of AWS?

Q

6 Advantages of Cloud Computing (DEFINITELY A TEST QUESTION)

A
  1. Trade capital expense for variable expense
    • with AWS you pay as you go (pay for what you use)
    • with AWS tax deductible in the same tax year
  2. Benefit from massive economies of scale
    • aggregated usage across hundreds of thousands of customers= lower variable cost for customers
  3. Stop guessing capacity
    • with AWS can adjust capacity based on demand
  4. Increase speed and agility
    • Speed= deploy resources easily and quickly
    • Agility= ability to react to change; speed to market
  5. Stop spending money running and maintaining data centers
  6. Go global in minutes
    • With AWS can easily deploy resources all over the world
