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 type of POSIX-compliant file storage suitable to be used as a file system and not for storing backups
Amazon Elastic File System (EFS)
Which AWS service should you use if you need to launch a highly scalable MySQL OLTP database?
Amazon Aurora
Is a MySQL and PostgreSQL-compatible relational database built for the cloud that combines the performance and availability of traditional enterprise databases with the simplicity and cost-effectiveness of open source databases
Amazon Aurora
This is 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
Amazon Redshift
Scalable, fast, and flexible non-relational database service
Amazon DynamoDB
Lets you deploy and run Memcached or Redis cache server nodes in the cloud
Amazon ElastiCache
A key design principle when running an application in AWS?
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
Logical coupling and Semantic coupling

What statement is correct regarding the components of the AWS Global Infrastructure?
An AWS Region contains multiple Availability Zones
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
A site that CloudFront uses to cache copies of your content for faster delivery to users at any location
Edge location
Consists of multiple Availability Zones (AZs)
AWS Region
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
- Security
- Reliability
- Performance Efficiency
- Cost Optimization
Which of the following cloud best practices reinforces the use of the Service-Oriented Architecture (SOA) design principle?
Decouple your components
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
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 of the following 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
Example 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
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
Well-Architected Framework
Based on agile methodology and is not exclusive to the AWS cloud computing model
Scrum Development Process
An open-source framework that you can use to build serverless applications on AWS
AWS Serverless Application Model
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
AWS Cloud Adoption Framework
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
