database calls are reads. what is the simplest way to scale the database without
downtime? - Answers -create a read replica

if you wanted to change to an instance type with more resources there would be
downtime

A new application requires a database that can allow writes to DB instances in multiple
AZ with read after write consistency. which solution meets these requirements? -
Answers -Amazon Aurora Multi-Master

This adds the ability to scale out write performance across multiple AZ and provides
configurable read after write consistency.

an organization is migrating a database into the AWS cloud. they require a managed
service for their MySQL database and need automatic failover to a secondary database.
which solution should they use? - Answers -Amazon RDS with multi-AZ

which IAM entity can be used to delegate permissions? - Answers -Role

condition element AKA condition block

Hibernating an instance - Answers -EC2 signals the operating system to perform
hibernation (suspend to disk). Hibernation saves the contents from the instance memory
ram to your Amazon EBS root volume. Amazon EC2 persists the instance's EBS root
volume and any attached data volumes

an organization has a unit with multiple member accounts. the company needs to
restrict the ability to launch only specific Amazon EC2 instance types. how can this
policy be applied across the accounts with the least effort? - Answers -create an SCP
with a deny rule that denies all but the specific instance types

AWS Glue - Answers -fully managed extract, transform, and load (ETL) service that
makes it easy for customers to prepare and load their data for analytics.

Scheduled Scaling - Answers -good for Predictable Workloads - so when you know
when and for how long you are going to need additional capacity

Simple Scaling - Answers -Good for unpredictable workloads.

with simple scaling, after scaling activity has started, the policy must wait for the scaling
activity or health check replacement to complete and the cooldown period to expire
before responding to additional alarms (in contrast to step scaling)

AWS recommends Step Scaling.

Step Scaling - Answers -increase or decrease the current capacity of your auto scaling
group based on a set of scaling adjustments, known as step adjustments.

The adjustments very based on the size of the alarm breach.

suitable for situations where the load is unpredictable.

Elastic File System - Answers -provides a simple, scalable, fully-managed elastic NFS
file system for use with AWS cloud services and on-prem resources. it can scale on
demand without disrupting applications growing and shrinking automatically as you add
or remove files.

you do not need to provision and manage capacity to accommodate growth.

multiple EC2 instances can access an Amazon EFS file system at the same time.

, Spot Block Instances - Answers -spot instances with a defination that are designed to
not be interrupted and will continuously run for the duration you select.

ideal for jobs that take a finite time to complete like batch processing and coding and
rendering modeling and analysis and continuous integration.

maximum duration of a spot block is 6 hours at a time

Amazon MQ - Answers -managed message broker service

Athena vs RDS / Aurora vs Redshift - Answers -Athena - query service that makes it
easy to analyze data in S3 using standard SQL. Athena is serverless so there's no
infrastructure to manage and you pay only for the queries that you run.

RDS / Aurora - not good for analyzing data sets on S3. these are both relational
databases used for transactional (not analytical) workloads

Redshift - enables you to run queries against exabytes of unstructured data in S3 with
no loading or ETL required. however red shift nodes run on EC2 instances so for
infrequent queries this is expensive.

Amazon Aurora Replicas - Answers -can be used to serve read traffic which offloads
requests from the main database

AWS Global Accelerator - Answers -direct users to different instances of the application
and different regions based on latency.

an endpoint needs to be configured

uses the vast congestion-free AWS global network to route TCP and UDP traffic to a
healthy application endpoint

Amazon Kinesis Data Streams - Shards vs. Partition Key - Answers -A data stream is a
set of shards.

-each shard has a sequence of data records.
-each data record is a sequence number that is assigned by kinesis data streams.

a shard is a uniquely identified sequence of data records in a stream.

A partition key is used to group data by a shard within a stream.

Elastic Fabric Adapter - Answers -This is an elastic network adapter with added
capabilities. The EFA lets you apply the scale flexibility and elasticity of the AWS cloud
to tightly coupled HPC (high performance computing apps). It is ideal for tightly coupled
apps as it uses the message passing interface MPI.
