Agenda

• General cloud concepts
• Cloud Benefits
• AWS Foundations
• AWS Services
• Labs and Exercises

General Cloud Concepts

• Someone’s else computer with:

  • “Infinite” resources
    • Most of the services can scale to unlimited values and also very fast
  • Elastic services
    • Services can scale up and down so you can only pay what you need
  • Easy and cheap to test new technologies
    • Because you only pay for what you use, and during the time you use, you can run tests with new technologies for a week and only pay for the resources consumed during that week.
  • Fast innovation pace
    • Being able to test without big investments, the feedback on tests are quicker and you can continuosly innovate

• Architecting and developing for the cloud

  • Pets vs Cattle
    • Instead of having servers that you will try to fix, you'll just kill it and replace it
  • Decoupled systems
    • Ideally there is no interdependency between your servers/services.
  • Ephemeral Environments
    • Components are not changed/upgraded. They are fully replaced and nothing is expected to be lost
  • Automation
    • Automation is an important factor to be able to recreate environments faster and without human errors

Cloud Benefits

• Many managed services
  • Most services can be consumed without any management required.
• Easy to test new solutions
  • Testing new solutions is cheaper and faster, speeding innovation
• No upfront investments
  • There is no need for initial investments in server/network equipments from day one.
• Pay as you go
  • You only pay for what you use, generally based on hours/minutes/seconds

AWS Foundations

• Availability Zone
  • Consider it as a Datacenter
  • Currently at 76
• Region
  • A geographical location with 2 or more AZs
  • AZ’s are physically separated by many kilometers, from any other AZ, although all are within 100 km (60 miles) of each other.
  • Currently at 24
• Edge Location
  • AWS Endpoint used for caching content(CDN)
  • Currently at 216 (Edge locations + Regional Edge caches)
