Q

Cloud Computing

A

Cloud Computing = the on-demand delivery of IT resources and applications via the internet.

With Cloud Computing, instead of having to design and build our own data centers, we access a data center and all of its resources via the internet - allowing us to scale up or down based on our actual needs

Q

Which feature of AWS allows you to deploy a new application for which the requirements may change over time?

A

Elasticity Elasticity refers to the power to scale computing resources up or down easily. Elasticity allows you to deploy your application without worrying about whether it will need more or less resources in the future. With elasticity, the infrastructure can scale on-demand.

Q

Business Value (TCO - AWS Cloud Economics)

A

Business Value (TCO): what you discuss with your customers before a sale to help them understand the value of AWS and how AWS will improve all aspects of their business’s performance and customer experience

It includes Total cost of Ownership + more

The value is delviered via activities like proofs of concept, architectural reviews, migration of workloads, etc.

Your job in business value engagement is to remove the financial issues off the top, and, once that’s done, a business value analysis is no longer needed.

Its’ more than demontrating cost savings

Q

Operational Excellence Pillar (AWS Well-Architected Framework)

A

Operational Excellence Pillar: ability to run and monitor systems to deliver business value and to continually improve supporting processes and procedures

Key ideas behind the Operational Excellence Pillar =

  • Managing and automating changes
  • Responding to events
  • Defining the standards to successfully manage daily operations

Operational Exellence Pillar’s 5 Design Principles =

  • Perform operations as code
  • Make frequent, small, reversible changes
  • Refine operations procedures frequently
  • Anticipate failure
  • Learn from all operational failures

Focus areas are:

Organization

Prepare

Operate

Evolve

Q

Security Pillar (AWS Well-Architected Framework)

A

Security Pillar: the ability to protect information, data, systems, and assets while delivering business value through risk assessments and mitigation strategies.

Secuirty Pillar’s Design Principles =

  • Implement a strong identity foundation
  • Enable traceability
  • Apply security at all layers
  • Automate security best practices
  • Protect data in transit and at rest
  • Keep people away from data
  • Prepare for security events

The security plillar covers five areas of concern.

  1. Identiy and access management
  2. Detection
  3. Infrastructure protection
  4. Data protection
  5. Incident response
17
Q

Reliability Pillar (AWS Well-Architected Framework)

A

Reliability Pillar: the ability of a system to recover from infrastructure or service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues

Ability to recover from failures and meet demand

Reliabiltiy Design Principles =

  • Automatically recover from failure
  • Test recovery procedures
  • Scale horizontally to increase aggregate workload availability
  • Stop guessing capacity
  • Manage change in automation

Reliability Pillar: focuses on the ability to recover from failure and meet demand in the following areas:

  • Foundations
  • Workload architecture
  • Change management
  • Failure management
18
Q

Performance Efficiency Pillar (AWS Well-Architected Framework)

A

Performance Efficiency Pillar: the ability to use computing resources efficiently to meet system requirements and to maintain that efficiency as demand changes and technologies evolve.

Performance Efficiency Pillar’s Design Principles =

  • Democratize advanced technologies
  • Go global in minutes
  • Use serverless architectures
  • Experiment more often
  • Consider mechanical sympathy

Q

Public Cloud + Beneftis of Public Cloud

A

Public Cloud = The IT services that you consume are hosted and delivered from a third-party and accessed over the Internet

Benefits of Public Cloud (AWS Cloud)

  • Variable expense, instead of capital expense
  • Economies of scale
  • Massive elasticity
21
Q

What are the 6 Advantages of the Cloud?

A

6 advantages of the Cloud =

  1. Trade capital expense for variable expense - Instead of investing in data centers before you know how you’re going to use them, pay only when, and for how much, you consume
  2. Benefit from massive economies of scale - Achieve a lower variable cost due to AWS’ scale
  3. Stop guessing about capacity - Eliminate guessing, scale as demand dictates.
  4. Increase speed and agility - Easily and quickly scale your usage
  5. Stop spending money running and maintaining data centers - Focus on business growth and innovation instead!
