Concepts and Components Flashcards
What is a region:
A physical location which consists of 2 or more availability zones
What is an availability zone:
1 or more discrete data centres, each with redundant power, networking and connectivity, housed in separate facilities
What is an edge location:
An endpoint for AWS used for caching content, normally consisting of CloudFront, Amazon’s Content Delivery Network (CDN)
What is Elastic Compute Cloud (EC2):
Mostly virtual machines (can be physical) inside the AWS platform - Compute section
What is Elastic Beanstalk:
Used for uploading code, mostly used by developers who don’t want to use/don’t understand AWS - not so relevant for this course - Compute section
What is Lambda:
Code that you upload to the cloud that you can control when it executes in response to events - no management required - Compute section
What is Lightsail:
Virtual private service for people who don’t want to understand AWS - gives you a server, an IP address and a management console - Compute section
What is S3:
Upload files into buckets in the cloud - simple storage service - Storage section
What is EFS:
Elastic File System - network attached managed file storage - Storage section
What is Glacier:
Data archival - cheap - Storage section
What is Snowball:
Used for large amounts of data (terabytes/petabytes) - to AWS data centre - write physically to a disk and send in manually - Storage/Migration section
What is Storage Gateway:
Virtual appliances - replicates info to S3 - 4 kinds of gateway - Storage section
What is RDS:
Relational Database Service - MySequel, Aurora, Oracle, etc - Databases section
What is DynamoDB:
Non-relational database service - Databases section
What is ElastiCache:
Caching commonly queried things from your server - frees up database service for other queries - Databases section
What is Red Shift:

What is AWS Migration Hub:
Tracking service- tracks applications - integrates with other services - Migration section
What is Application Discovery Service:
Automated set of tools that detects what apps you have and what their dependencies are - Migration section

What is Server Migration Service:
Helps migrate physical and virtual servers to AWS - Migration section
What is VPC:
Virtual Private Cloud - configure availability zones and firewalls etc. - Networking and Content Delivery section
What is CloudFront:
Amazon’s content delivery network - stores data closer to other user’s edge locations e.g. London to Sydney so you can access it from a nearer edge location - stores media assets - Networking and Content Delivery section
What is Route 53:
DNS service - domain name system - looks up AWS IPB4 and IPB6 addresses - Networking and Content Delivery section
What is API Gateway:
Create, deploy and manage your own APIs for your other services to connect to - Networking and Content Delivery section
What is Direct Connect:
Way of running a dedicated line from your head office/data centre to Amazon - directly connects to VPC as well - Networking and Content Delivery section
What is CloudFormation:
Scripting infrastructure to code - use code to deploy things anywhere - Management Tools section
What is CloudTrail:
Logs API calls/changes - default - Management Tools section
What is Config:
Monitors configuration of entire AWS environment - can use timer to look at previous times - Management Tools section
What is OpsWorks:
Automates environments in AWS - like Elastic Beanstalk but more robust - Management Tools section
What is Trusted Advisor:
Gives advice on may disciplines - warns of risks - tells you how to save money/time/etc. - Management Tools section
What is Polly:
Takes text and turns it to speech - Machine Learning section (won’t be in exam but will be used in this course)
What is EMR:
Elastic Map Reader - Processes large amounts of data - Analytics section
What is Kinesis:
Ingests large amounts of data to AWS - like a hashtag many people use - realtime data - Analytics section
What is Data Pipeline:
A way to move data between different AWS services - Analytics section
What is IAM:
Identity Access Management - does what is says on the tin - Security, Identity and Compliance section
What is Cognito:
Device authentication - also allows the app/other to access some aspects of AWS - Security, Identity and Compliance section
What is Inspector:
Run tests for vulnerabilities - can be scheduled - creates reports - Security, Identity and Compliance section
