Module 1 - Architecture Fundamentals Flashcards
What are some of the global cloud-based products AWS offers? There are 11.
compute, storage, database, analytics, networking, mobile, developer tools, management tools, Internet of Things (IoT), security, and enterprise applications
What tools allow you to interact with the AWS API to create and manage your AWS services
AWS Management Console (GUI),
AWS CLI,
Cloud Development Kit (CDK) or Software Development Kit(SDK),
CloudFormation(Infrastructure as Code (IAC))
What is AWS EC2?
AWS Elastic Compute Cloud. It’s a web service that allows you to build and run an application in the cloud. Basically, it’s somebody else’s computer.
What is the barest-bones service?
An unmanaged service running on EC2. AWS handles the physical server, power, and OS installation. You handle everything else.
What is serverless architecture?
A way to build and run applications and services without having to manage infrastructure. You focus on the code and someone else handles all the server management. (It’s still run on servers!)
Describe a data center
A secure building that holds 1000s of servers.
What is an Availability Zone (AZ)?
A group of one or more data centers. These are multiple, isolated areas within a particular geographic location. They are connected using high-speed private links. Allows for high availability, fault isolation.
What is an AWS Region?
A collection of Availability Zones that are geographically separate. You choose your region(s) when you sign up. AWS does not automatically replicate resources across regions.
How do you choose which region is appropriate?
- Governance and legal requirements
- Latency – Close proximity to customers means better performance.
- Service availability – Not all AWS services are available in all Regions.
- Cost – Different Regions have different costs.
What is an AWS Local Zone?
A type of infrastructure deployment that places compute, storage, database, and other select AWS services close to large population and industry centers. Each AWS Local Zone location is an extension of an AWS Region. This would be for high-demand applications like streaming, VR, gaming, or if you need to have data in a certain place for legal reasons like healthcare or government.
What is an edge location?
The nearest point to a requester of an AWS service, usually in major cities. They receive the request and cache copies of the content. Used if you need lower latency.
What is a regional edge cache?
It’s a server that caches information that is not accessed often enough to be stored in an edge location, but it saves you from having to go all the way back to the origin server.
What’s the difference between a Local Zone and an Edge Location?
The Edge Location is used to host the web content (Static or Dynamic) and it may be in the form of a cache.
Local Zone is mainly used for infrastructure deployment that places compute, storage, database, and other select AWS services close to a large population.
What is Amazon S3?
Amazon Simple Storage Service. Stores data as objects in buckets through a web service interface. It’s a key-value store.
What is AWS Well-Architected?
A framework to help architects build infrastructures using best practices. It started as a document, now there is a tool in the AWS Management Console to help you evaluate your workloads and issues without needing a solutions architect.
