Domain 1: Cloud Concepts
Define the AWS Cloud
Introduction
The AWS Cloud delivers versatile infrastructure services on-demand with pay-as-you-go pricing.
Benefits of the AWS Cloud:
Security
Multiple layers of privacy to safeguard data.
Reliability
Designed for continuous, fault-tolerant access.
Elasticity
Scale up or down based on workload.
Global Reach
Access to data centers around the world.
Shifting Focus to Business Value:
AWS lets businesses shift from managing infrastructure to focusing on activities that generate revenue.
Which of the following is NOT a benefit of the AWS Cloud?
a) Security b) Limited Reach c) Scalability d) Elasticity
b) Limited Reach
Identify aspects of AWS Cloud economics
Introduction
Understanding AWS Cloud economics helps make effective decisions.
Total Cost of Ownership (TCO):
OpEx
Recurring costs for daily operations.
CapEx
Upfront costs to acquire assets.
Labor Costs
Costs associated with manual, on-premises tasks.
Software Costs
Costs related to licensing when transitioning to cloud.
Cost-saving Operations in Cloud:

Explain different cloud architecture design principles
Introduction
Designing for the cloud requires a different approach than traditional architectures.
Design Principles:
Design for Failure
Assume failures will happen; design to be resilient.
Decouple Components
Avoid monolithic architectures; each component should be separate.
Implement Elasticity
Use AWS to auto-scale resources based on demand.
Think Parallel
Use AWS's global infrastructure for better performance and redundancy.
What does "Think Parallel" in cloud design mean?
a) Using one data center b) Sequential processing c) Deploying resources in multiple regions d) Using a single region
c) Deploying resources in multiple regions
