AWS Cloud Practitioner Certification: AWS Global Infrastructure

Key business factors to deploy your app in a region:

• Compliance:
  • Business policies.
  • Laws.
  • Standards.

• Proximity:
  • Proximity to the customers to deliver the product at high speed.

• Feature availability (AWS products):
  • Newest products, services or features of AWS can be deploy first in some region and then expand to others.

• Pricing:
  • One region can be more expensive than others.

Availability Zones (AZ) = Data Centers

Good practice ⇒ Runs multiple EC2 located each one in different AZs to prevent disaster shut down.

Edge locations

• It’s a site that Amazon CloudFront uses to store cached copies of your content (videos, files, APIs, …) closer to your customers for faster deliveries.

• Amazon CloudFront is a content delivery service (CDS). You can think also as a content delivery network (CDN).

• AWS Outposts extends AWS infrastructure and services to different locations, including your on-premise data center.

Ways to interacting with AWS

• CLI. (Console)

• Management console (Web interface)

• AWS Software Development Kits (SDK) (Through programming languages)

• Using AWS Elastic Beanstalk
  • Takes a script and desired configuration and builds out your environment.
  • AWS Elastic Beanstalk takes care of EC2 instances allocation, auto scaling groups, and auto load balancing configuration.
  • Fast deployment purpose.

• Using AWS CloudFormation
  • Use JSON or YAML configuration files.
  • Create parallel environments with a share pool of services in the backend.
