Introduction to AWS

What is the cloud?


With cloud computing, you can stop thinking of your infrastructure as hardware, and instead think of it (and use it) as software.

Six Advantages of Cloud Computing

Trade upfront expense for variable expense

  • Upfront expenses
    • Invest in technology resources before using them
  • Variable expenses
    • Pay only for what you use

Benefit from massive economies of scale

  • Smaller scale
    • Pay higher prices based on only your own usage
  • Economies of scale
    • Benefit from customers' aggregated usage

Stop guessing capacity

  • Stop guessing on your infrastructure capacity needs
  • Scale in and scale out as needed

Increase speed and agility

  • Data centers
    • Weeks between wanting resources and having resources
  • Cloud computing
    • Minutes between wanting resources and having resources

Stop spending money on running and maintaining data centers

Go global in minutes

  • Quickly deploy applications worldwide
  • Use the AWS global infrastructure

Choosing a region

Data residency regulatory compliance

  • Are there relevant Region data privacy laws?
  • Can customer data be stored outside the country?

Proximity of users to data

  • Small differences in latency can impact customer experience
  • Choose the Region closest to your users

Cost-effectiveness

  • Costs vary by Region
  • Evaluate cost-effectiveness of replicating data to another Region

AWS Core Infrastructure and Services

Cloud Computing Deployment Models

On-premises deployment

  • Use virtualization and resource management tools to deploy resources
  • Use application management and virtualization technologies to increase resource usage

Hybrid deployment

  • Connect cloud-based resources to on-premises infrastructure
  • Integrate cloud-based resources with legacy IT applications

Cloud-based deployment

  • Run all parts of the application in the cloud
  • Migrate existing applications to the cloud
  • Design and build new applications in the cloud
