AWS Amazon Web Services: Module 10

Module 10 The Cloud Journey

Learning objectives
In this module, you will learn how to:
Summarize the five pillars of the Well-Architected Framework.
Explain the six benefits of cloud computing.

The five pillars of the AWS Well-Architected Framework:

Operational excellence
Security
Reliability
Performance efficiency
Cost optimization

Six advantages of cloud computing:

Trade upfront expense for variable expense.
Benefit from massive economies of scale.
Stop guessing capacity.
Increase speed and agility.
Stop spending money running and maintaining data centers.
Go global in minutes.

Operational excellence
Operational excellence is the ability to run and monitor systems to deliver business value and to continually improve supporting processes and procedures.
Design principles for operational excellence in the cloud include performing operations as code, annotating documentation, anticipating failure, and frequently making small, reversible changes.

Security
The Security pillar is the ability to protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies.
When considering the security of your architecture, apply these best practices:
Automate security best practices when possible.
Apply security at all layers.
Protect data in transit and at rest.

Reliability
Reliability is the ability of a system to do the following:
Recover from infrastructure or service disruptions
Dynamically acquire computing resources to meet demand
Mitigate disruptions such as misconfigurations or transient network issues
Reliability includes testing recovery procedures, scaling horizontally to increase aggregate system availability, and automatically recovering from failure.

Performance efficiency
Performance efficiency is the ability to use computing resources efficiently to meet system requirements and to maintain that efficiency as demand changes and technologies evolve.
Evaluating the performance efficiency of your architecture includes experimenting more often, using serverless architectures, and designing systems to be able to go global in minutes.

Cost optimization
Cost optimization is the ability to run systems to deliver business value at the lowest price point.
Cost optimization includes adopting a consumption model, analyzing and attributing expenditure, and using managed services to reduce the cost of ownership.

Question

1. Which pillar of the AWS Well-Architected Framework focuses on the ability of a workload to consistently and correctly perform its intended functions?

Reliability

The Operational Excellence pillar includes the ability to run workloads effectively, gain insights into their operations, and continuously improve supporting processes to deliver business value.

The Performance Efficiency pillar focuses on using computing resources efficiently to meet system requirements, and to maintain that efficiency as demand changes and technologies evolve.

The Security pillar includes protecting data, systems, and assets, and using cloud technologies to improve the security of your workloads.

6 main benefits of using the AWS cloud

6 ADVANTAGES OF CLOUD COMPUTING:

Trade upfront expense for variable expense.
Benefit from massive economies of scale.
Stop guessing capacity.
Increase speed and agility.
Stop spending money running and maintaining data centers.
Go global in minutes.

Question:
Which process is an example of benefiting from massive economies of scale?
Receiving lower pay-as-you-go prices as the result of AWS customers’ aggregated usage of services

NOTE
Deploying an application in multiple Regions around the world: This process is an example of Go global in minutes.

Paying for compute time as you use it instead of investing upfront costs in data centers: This process is an example of Trade upfront expense for variable expense.

Scaling your infrastructure capacity in and out to meet demand: This process is an example of Stop guessing capacity.
