Any object uploaded to S3 must first be placed into either the Standard, Reduced Redundancy,
or Infrequent Access storage class. Once in S3 the only way to move the object to glacier is through a lifecycle policy.

White papers are a collection of technical documents that outlines many AWS relevant topics.

CloudFront is AWS\'s content delivery network (CDN) service. You can use it to cache web content at edge locations what are closest to you customers. This will decrease latency for the customer and improve overall performance.

You must contact AWS before doing any penetration testing on your account. If you do not notify AWS first, they may shut down your account.

As an AWS user, you can create your applications infrastructure and duplicate it. By placing duplicate infrastructure in multiple regions, high availability is created because if one region fails you have a backup (in a another region) to use.

An AWS region is an isolated geographical area that is is comprised of three or more AWS Availability Zones.

The AWS Trusted Advisor program will analyze your account with check in the following categories: Cost Optimization Performance Security Fault Tolerance

AWS Service documentation is a collection of documents specific to each AWS service. They contain detailed how-to\'s, as well as technical walkthroughs and specifications.

When an IAM user is created, that user has NO access to any AWS services. To gain access to an AWS server, an IAM user must have permission granted to them. This is done by attached an IAM access policy to their IAM user (or through an attached group). However, just being in a group does not
grant access. A proper policy would need to be attached to that group.

Fault tolerance, scalability, elasticity, and high availability are the four primary benefits of AWS/the cloud.

Fault tolerance describes the concept of a system (in our case a web application) to have failure in some of its components and still remain accessible (highly available). Fault tolerant web applications will have at least two web servers (in case one fails).

Redshift is a database offering that is fully-managed and used for data warehousing and analytics, including compatibility with existing business intelligence tools.

RDS is a SQL database service (that offers several database engine options), and DynamoDB is a NoSQL database option that only offers one NoSQL engine.

All four answers listed are reasons why a company may decide to use AWS over an on-premises data center.

Glacier should be used for (and is specifically designed for) long-term , archival storage.

CloudTrail is AWS\'s logging service used to log actions taken by users in your AWS account.

CloudFront allows you to cache content at edge locations. When a request is made for that content, the request is sent to an edge location (not your applications hardware), so the edge locations will absorb any DDoS attack and protect your underlining hardware.

RDS offers the following SQL options: Aurora MySQL MariaDB PostreSQL Oracle Miscrosft SQLServer

Elasticity is the concept that a system can easily (and cost-effectively) both increase in capacity based on-demand and also shrink in capacity based on-demand. Auto Scaling on AWS is specifically designed to (automatically) increase and decrease server capacity based on-demand.

Simple Notification Service (SNS) is what publishes messages to SMS and/or email endpoints.
