AWS Certified Cloud Practitioner (CLF-C01)

1. Fundamental Cloud Concepts for AWS

   • Traditional Data Centers
     • Large up-front investment
     • Forecasting demand is difficult
     • Slow to deploy new data centers and servers
     • Maintaining data centers is expensive
     • You own all of the security and compliance burden
   • Benefits of Cloud Computing
     • Trade capital expense for variable expenses
     • Benefit from massive economies of scale
     • Stop guessing capacity
     • Increase speed and agility
     • Stop spending money maintaining data centers
     • Go global in minutes
   • Agility
     • The cloud lowers the cost of trying new ideas or business processes
     • Reduces the time required to maintain infrastructure
     • Reduces risk for the organization around security and compliance
     • Provides access to emerging technologies
   • Cloud Computing Models
     • IaaS
     • PaaS
     • Saas
   • “Cloud computing is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform via the Internet with pay-asyou- go pricing.” Amazon Web Services
   • Cloud Deployment Models
     • Public Cloud
     • On-Premises (Private Cloud)
     • Hybrid: Cloud applications connected to a private data center

2. AWS Global Infrastructure

   • Regions
     • geographic location
     • has a cluster of data centers
   • Availability Zones
     • one or more data centers
     • included with each AWS Region
     • Located within the geographic area of the AWS Region
     • Redundant power, networking and connectivity
   • Edge Locations
     • Used as nodes of a global content delivery network (CDN)
     • Utilized by Amazon CloudFront and Amazon Route 53
     • Located globally at over 200 different locations
     • Allows AWS to serve content from locations closest to users

3. Understanding Cloud Economics

   • Capitalized Expenditure (CapEx)
     • When building a data center, an organization invests in upfront costs for the building, servers, and supporting equipment. This type of expense to attain a fixed asset is referred to as a Capitalized Expenditure or CapEx.
   • Operating Expenditure (OpEx)
     • The regular day to day expenses of a business are considered Operating Expenditures or OpEx. After the initial build of a data center, ongoing connectivity, utility, and maintenance costs would be considered OpEx.
   • Financial Implications
     • Manage Your Own Data Center
       • Large Up-front Costs (CapEx)
       • Potential for either Under-used Capacity or Unmet Demand
       • Increasing Capacity Takes Time and Additional Investment (CapEx)
       • Monthly Costs will Map to Predicted Infrastructure Needs
     • Leverage Cloud Infrastructure Large
       • No Up-front Investment
       • You Pay as You Go for Infrastructure (OpEx)
       • Capacity Scales to Meet User Demand and Can Be Provisioned Immediately
   • Organizing and Optimizing AWS Costs
     • AWS Cost Explorer
     • AWS Budgets
     • AWS Cost Planning Tools
       • AWS TCO Calculator
       • AWS Simple Monthly Calculator
