AWS General Flashcards
(35 cards)
What is cloud computing?
On-demand delivery of IT resources and applications through the internet with pay-as-you-go pricing
What is another name for on-premises deployment?
Private cloud deployment
How does the scale of cloud computing help you to save costs?
The aggregated cloud usage from a large number of customers results in lower pay-as-you-go prices
You want to use an Amazon EC2 instance for a batch processing workload. What would be the best Amazon EC2 instance type to use?
Compute optimized
You want to use an Amazon EC2 instance to provide a balance of compute, memory, and networking resources. What would be the best Amazon EC2 instance type to use?
General purpose
You want to use an Amazon EC2 instance to process large datasets in memory, such as high-performance databases. What would be the best Amazon EC2 instance type to use?
Memory optimized
You want to use an Amazon EC2 instance for workloads that require high, sequential read and write access to large datasets on local storage. What would be the best Amazon EC2 instance type to use?
Storage optimized
What are the contract length options for Amazon EC2 Reserved Instances?
1 year and 3 years
You have a workload that will run for a total of 6 months and can withstand interruptions. What would be the most cost-efficient Amazon EC2 purchasing option?
Spot Instance
What is an example of Elastic Load Balancing?
Ensuring that no single Amazon EC2 instance has to carry the full workload on its own.
Elastic Load Balancing is the AWS service that automatically distributes incoming application traffic across multiple resources, such as Amazon EC2 instances. This helps to ensure that no single resource becomes overutilized.
Services used to deploy and manage containerized applications
Elastic Container Service (Amazon ECS) and Amazon Elastic Kubernetes Service (Amazon EKS)
EC2 instance type ideal for short-term, irregular workloads that cannot be interrupted. No upfront costs or minimum contracts apply. The instances run continuously until you stop them, and you pay for only the compute time you use.
On-Demand Instances
Allow you to reduce your compute costs by committing to a consistent amount of compute usage for a 1-year or 3-year term
Amazon EC2 Savings Plans
Billing discount applied to the use of On-Demand Instances in your account, purchasable for a 1-year or 3-year term
Reserved Instances
EC2 instance type ideal for workloads with flexible start and end times, or that can withstand interruptions. Uses unused Amazon EC2 computing capacity and offers cost savings at up to 90% off of On-Demand prices
Spot Instances
EC2 instance type that leverages physical servers with Amazon EC2 instance capacity that is fully dedicated to your use
Dedicated Hosts
What are the four key factors to use when choosing an AWS Region?
Compliance
Proximity
Feature availability
Pricing
A distinct location within a Region that’s insulated from failures and provides inexpensive, low-latency network connectivity within the same Region.
Availability Zone
Uses a network of edge locations to cache content and deliver content to customers all over the world.
Amazon Cloudfront
An AWS content delivery service that helps you improve the performance, reliability, and availability of your websites and applications.
A web service you can use to create a new DNS service or to migrate your existing DNS service to the cloud.
Route 53
A fully managed service that extends AWS infrastructure, APIs, and tools to customer premises
Amazon Outposts
Web-based interface for accessing and managing AWS services
AWS Management Console
You can quickly access recently used services and search for other services by name, keyword, or acronym. The console includes wizards and automated workflows that can simplify the process of completing tasks.
A graphical interface to manage compute, storage, and other cloud resources.

You can quickly access recently used services and search for other services by name, keyword, or acronym. The console includes wizards and automated workflows that can simplify the process of completing tasks.
A unified downloadable and configurable tool for managing AWS services. Control multiple AWS services from the command line and automate them through scripts.
AWS Command Line Interface (CLI)
By using AWS CLI, you can automate the actions that your services and applications perform through scripts. For example, you can use commands to launch an Amazon EC2 instance, connect an Amazon EC2 instance to a specific Auto Scaling group, and more.
