workloads that process large datasets/databases in memory
Amazon EC2; Accelerated computing - ANSWER-use hardware accelerators, or coprocessors, to
perform some functions more efficiently than is possible in software running on CPUs
Amazon EC2; Storage optimized - ANSWER-designed for workloads that require high,
sequential read and write access to large datasets on local storage
Amazon EC2; Pricing Types (5) - ANSWER-On-Demand
Reserved instances
EC2 Instance Savings Plans
Spot Instances
Dedicated Hosts
Amazon EC2 Pricing; On-Demand- (3 Definition points) - ANSWER-*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.
Amazon EC2 Pricing; Reserved instances (2) - ANSWER-*Standard Reserved Instances
if you know the EC2 instance type and size you need for your steady-state applications and in
which AWS Region you plan to run them.
*Convertible Reserved Instances
If you need to run your EC2 instances in different Availability Zones or different instance types
Amazon EC2 Pricing; EC2 Instance Savings Plans (Contract and Savings %) - ANSWER-* 1-
year or 3-year term
* 72 percent compared to On-Demand rates.
Any usage up to the commitment is charged at the discounted Savings Plans rate
Any usage beyond the commitment is charged at regular On-Demand rates.
Amazon EC2 Pricing; Spot Instances - ANSWER-*workloads with flexible start and end times,
or that can withstand interruptions.
*use unused Amazon EC2 computing capacity and offer you cost savings at up to 90% off of On-
Demand prices.
Amazon EC2 Auto Scaling Types (5) - ANSWER-desired capacity
predictive scaling
dynamic scaling
minimum capacity
maximum capacity
Amazon EC2 Auto Scaling Definition - ANSWER-enables you to automatically add or remove
Amazon EC2 instances in response to changing application demand.
Amazon EC2 Auto Scaling; dynamic - ANSWER-esponds to changing demand.
Amazon EC2 Auto Scaling; predictive - ANSWER-automatically schedules the right number of
Amazon EC2 instances based on predicted demand.
Amazon EC2 Auto Scaling; minimum - ANSWER-is the number of Amazon EC2 instances that
launch immediately after you have created the Auto Scaling group.
Amazon EC2 Auto Scaling; desired - ANSWER-What is the ideal capacity to run the application
, Amazon EC2 Auto Scaling; maximum - ANSWER-The most instances you want to scale up in
case of demand.
Elastic Load Balancing - ANSWER-is the AWS service that automatically distributes incoming
application traffic across multiple resources, such as Amazon EC2 instances.
Elastic Load Balancing; load balancer - ANSWER-acts as a single point of contact for all
incoming web traffic to your Auto Scaling group.
Amazon Simple Notification Service (Amazon SNS) - ANSWER-is a publish/subscribe service.
Using Amazon SNS topics, a publisher publishes messages to subscribers.
subscribers can be web servers, email addresses, AWS Lambda functions, or several other
options.
Amazon Simple Queue Service (Amazon SQS) - ANSWER-is a message queuing service where
you can send, store, and receive messages between software components, without losing
messages or requiring other services to be available.
AWS Lambda - ANSWER-AWS service for serverless computing
is a service that lets you run code without needing to provision or manage servers.
You pay only for the compute time that you consume
Charges apply only when your code is running.
Amazon Elastic Container Service - ANSWER-container management system enables you to run
and scale containerized applications
Amazon Elastic Container Service; Containers - ANSWER-standard way to package your
application's code and dependencies into a single object.
Amazon Elastic Container Service; Docker - ANSWER-*software platform that enables you to
build, test, and deploy applications quickly.
*can use API calls to launch and stop Docker-enabled applications.
Amazon Elastic Kubernetes Service (EKS) - ANSWER-service that you can use to run
Kubernetes
Kubernetes - ANSWER-Open-source software that enables you to deploy and manage
containerized applications at scale.
AWS Fargate - ANSWER-*serverless compute engine for containers.
*manages your server infrastructure for you.
Runs Amazon ECS and Amazon EKS.
