  • Open-source software development framework to define
    your cloud application resources using familiar programming
    languages
  • Preconfigures cloud resources with proven defaults using
    constructs

Q

AWS CloudFormation

A
  • Infrastructure is provisioned consistently, with fewer
    mistakes (human error)
  • Less time and effort than configuring resources manually
  • Free to use (you’re only charged for the resources
    provisioned)
  • A template is a YAML or JSON template used to describe the
    end-state of the infrastructure you are either provisioning or
    changing
  • CloudFormation creates a Stack based on the template
  • Can easily rollback and delete the entire stack as well

Q

Amazon CloudFront

A
  • CloudFront is a content delivery network (CDN) that allows
    you to store (cache) your content at “edge locations” located
    around the world
  • This allows customers to access content more quickly and
    provides security against DDoS attacks
  • CloudFront can be used for data, videos, applications, and
    APIs
  • CloudFront reduces latency for global users

20
Q

How do you Pay less by using more

A
  • Pay less using volume-based discounts
  • Tiered pricing means the more you use the lower the unit
    pricing
