Presentation Section​

AWS Core Services

Presenters: Alvin Yu, Christopher Coco, Nick Bottari

IAM:

  • Identity Access MAnagement
  • Manage User Accounts and grant fine grained access to AWS Resources
  • Mainly used to grant secure premissions to differnt components of your application.
    IAM supports MFA

AWS EC2:

  • Launches a virtual machine with well defined resources
  • General purpose. Can run databases, APIs, storage, websites.
  • Billed based on:
    • How LONG the service runs
    • How much DATA is transferred
    • How much STORAGE is attached

AWS Lambda:

  • Runs without provisioning server resources
  • Only billed for the TIME the service runs
  • Billed in GB-seconds

What is an API:

  • Application Programming Interface
  • Middleman between two pieces of software
  • REST API - type of API for HTTP
    • Representational State Transfer (REST)
    • GET, POST, PUT, PATCH, DELETE

AWS Lambda vs EC2:

  • EC2 - Constant running service (IE web server)
  • Lambda - Occasion operations that need to be run (IE the club's attendance bot)

AWS API Gateway:

  • AWS Service to proxy and handle HTTP

AWS S3:

  • Object Storage (not a filesystem, more like an API for uploading, and downloading files)
  • Stores "files" as "objects", which are in turn stored in buckets
  • Bucket names must be unique in global namespace
  • Billing based on:
    • Storage used
    • PUT, GET, DELETE requests

How to share S3:

  • Get temporary PRESIGNED URL
  • Can Upload, download images with REST API
  • Example of accessing files on S3 for non-aws users.

AWS CDK:

  • Generates CloudFormation templates, a declerative way of specifying which AWS services to launch.
  • Can be written with Typescript, JS, Python, Golang

Fireship AWS Video

  • EC2 was the one the first and most fundamental AWS Services
  • Lambda is Serverless
    • Traffic scaling happens in the background
  • Outposts is a way to run your own servers with AWS APIs.
  • Elastic Container Registery - A place to host your Docker containers
  • AWS S3 was the first AWS Service
  • Elastic Block Storage - Best for high data throughput
  • DynamoDB - Scales fast
  • AWS RDS - Aurora, MySQL, PostgreSQL
  • Lake Formation - Creating Data Lakes - Storage unstructed data
  • AWS Bedrock - Sagemaker
    • Uses Pytorch or TF
    • Connects to a Juypter Notebook to do development
  • Security
    • AWS IAM
    • AWS Cognito
    • AWs SNS
    • AWS SES
  • AWS Amplify

🧑‍💻 Hands On Section​

Beginning development on PhotoSky using Github Codespaces.

Followed through with preliminary configuration of the project, understand the backend architecture, and begin implementing the CDK stack.

Following through the PhotoSky Activity to the Implementing AWS CDK Stack section.
