Domain 1.0 Cloud Concepts Flashcards
Are designed to be the lowest-cost Amazon S3 storage classes, allowing you to archive large amounts of data at a very low cost. This makes it feasible to retain all the data you want for use cases like data lakes, analytics, IoT, machine learning, compliance, and media asset archiving. You pay only for what you need, with no minimum commitments or up-front fees

A key design principle when running an application in AWS? When you want a design to not depend on each but continue to function.
Loose coupling
This means that IT systems should be designed in a way that reduces interdependencies — a change or a failure in one component should not cascade to other components
Loose coupling
Are related to object-oriented programming and not a key design principle in AWS

What statement is correct regarding the components of the AWS Global Infrastructure?
An AWS Region contains multiple Availability Zones

A service that lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define
Amazon Virtual Private Cloud (VPC)
A cloud design principle which supports growth in users, traffic, or data size with no drop-in performance
Scalability
Internalizes the concept of parallelization when designing architectures in the cloud. It advocates to not only implement parallelization wherever possible but also automate it because the cloud allows you to create a repeatable process very easily
Think Parallel
Encourages you to be a pessimist when designing architectures in the cloud; assume things will fail
Design for failure
The Well-Architected Framework Five Pillars
- Operational Excellence

Availability Zones are physically separated by a meaningful distance from any other AZ, although all are within 100 km or 60 miles of each other. What is the primary reason why Availability Zones are set up the way they are now?
To keep them as far apart from each other in case of a disaster
Auto-Scaling based on demand is an implementation of which AWS cloud best practice?
Implement elasticity
Elasticity can be implemented in three ways
- Proactive Cyclic Scaling
- Proactive Event-based Scaling
- Auto-scaling based on demand
A company is planning to use AWS Cloud to augment the resources of their on-premises data center to better serve their customers around the world. How does a company benefit from using AWS?
Benefit from massive economies of scale
Has been developed to help cloud architects build secure, high-performing, resilient, and efficient infrastructure for their applications based on five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization

What are the 6 strategies for Migration
Rehosting
Replatforming
Refactory
Repurchasing
Retaining
Retiring
also known as “lift-and-shift” involves moving applications without changes.
Rehosting
also known as “lift, tinker, and shift,” involves making a few cloud optimizations to realize a tangible benefit. Optimization is achieved without changing the core architecture of the application.
Replatforming
Migration strategy involves reimagining how an application is architected and developed by using cloud-native features. driven by a strong business need to add features, scale, or performance that would otherwise be difficult to achieve in the application’s existing environment
Refactory
involves moving from a traditional license to a software-as-a-service model.
Repurchasing
consists of keeping applications that are critical for the business in the source environment. This might include applications that require major refactoring before they can be migrated, or, work that can be postponed until a later time.
Retaining
is the process of removing applications that are no longer needed.
Retiring
