Domain 1: 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
Amazon S3 Glacier and S3 Glacier Deep Archive
Amazon Elastic File System (EFS)
File storage service suitable
to be used as a file system
and not for storing backups
( POSIX-compliant )
Which AWS service should you use
if you need to launch a highly scalable MySQL
OLTP (Online Transaction Processing) database?
Amazon Aurora
Amazon Aurora
Relational Database built for the cloud
( MySQL and PostgreSQL-compatible )
That combines: - Performance and Availability of traditional databases & - Simplicity and Cost-effectiveness of open source databases
Amazon Redshift
A data warehousing solution which is best for
OLAP (online analytic processing) workloads and business intelligence (BI) applications which require complex queries against large datasets
What is a scalable, fast, and flexible non-relational database service ?
Amazon DynamoDB
What lets you deploy and run Memcached or Redis cache server nodes in the cloud
Amazon ElastiCache
What is a key design principle when running an application in AWS?
Loose coupling / Microservices
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
What is related to object-oriented programming and not a key design principle in AWS ?
Logical coupling and Semantic coupling
What are the Regional services in AWS?
- Amazon EFS
- AWS Batch
- Amazon EC2 key pairs
- Amazon Machine Image
- AWS Lambda
- AWS CloudTrail
- Amazon VPC
What are the Global services in AWS?
- AWS Security Token Service
- Amazon Route 53
- Amazon CloudFront
- AWS IAM
- AWS WAF
- Amazon S3
What are Zonal services that are tied to a particular availability zone where it is launched ?
Amazon EC2 Instances Amazon Elastic Block Stores Amazon FSx Amazon Elastic Load Balancers Amazon Elastic Kubernetes Service Amazon Elastic Container Service Amazon RDS
AWS Device Farm
An application testing service that lets you improve the quality of your web and mobile apps by testing them across an extensive range of desktop browsers and real mobile devices; without having to provision and manage any testing infrastructure
AWS Mobile Hub
A service that enables even a novice to easily deploy and configure mobile app backend features using a range of powerful AWS services
AWS Ground Station
This service is for controlling satellite communications and processing data using satellites
Amazon Lumberyard
This is a game engine service for creating games
AWS Security Bulletin
This AWS service is a security announcement provider service
What is a Component of AWS Global Infrastructure which consists of
one or more discrete data centers each with
redundant power, networking, and connectivity,
and housed in separate facilities ?
Availability Zone
What is a physical site that CloudFront uses to cache copies of your content for faster delivery to users at any location ?
Edge locations
What consists of multiple Availability Zones (AZs) ?
An AWS Region
What is 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)
What is a cloud design principle which
supports growth in users, traffic, or data size
with no drop-in performance ?
Scalability
Think Parallel
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
Design for failure
Encourages you to be a pessimist when designing architectures in the cloud; assume things will fail
The Well-Architected Framework Five Pillars
- Operational Excellence
- Security
- Reliability
- Performance Efficiency
- Cost Optimization
What best practice reinforces the use of the
Service-Oriented Architecture (SOA) design principle?
Decouple your components
What is a fully managed database in AWS that can be used to store JSON documents?
Amazon DynamoDB
When a company uses AWS and
decouple from their on-premises data center,
they will be able to have which of the following benefits?
Reduce time to market and Decrease your TCO
The use of multi-threading in your Amazon S3 requests via the Multipart Upload API is an example of which AWS cloud best practice?
Think parallel
What is tied to a specific Availability Zone where it was launched?
EBS Volume
EC2 instance ID is tied to?
AWS Region
A company is planning to deploy their
high-frequency trading (HFT) application
which will store constantly changing financial data
in AWS and require low latency access.
Which AWS services below should you use?
Amazon EFS and Amazon RDS
Which practices demonstrate operational excellence in AWS cloud?
- Deploy small, incremental changes to your production servers using AWS CodeDeploy
- Perform monthly game days on your AWS environment
Example of IaaS in AWS ?
Amazon EC2
Examples of PaaS in AWS ?
Amazon Lightsail Amazon Elastic Beanstalk Amazon GameLift Amazon Relational Database Service (RDS) Amazon Elastic Container Service (ECS)
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
Well-Architected Framework
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 is based on agile methodology and is not exclusive to the AWS cloud computing model ?
Scrum Development Process
AWS Serverless Application Model
An open-source framework that you can use to build serverless applications on AWS
AWS Cloud Adoption Framework
This is primarily used to help organizations design and travel an accelerated path to successful cloud adoption.
AWS Professional Services created this which can help you build a comprehensive approach to cloud computing across your organization, and throughout your IT lifecycle
What is the cloud computing model for services like Amazon RDS and Amazon ECS?
PaaS
Amazon RDS and ECS are considered PaaS because you don’t need to worry about setting up servers, storage, and network. You only manage the application and the data
AWS Reference Architecture Diagrams
A collection of technical resources to help you build industry-tested architectures more effectively and efficiently in the AWS Cloud
