# Week 0 — Billing and Architecture

Discussing the format of the boot camp?

  • This is a 14-week Boot camp from February 11 until the end week of May 2023.
  • Boot camp will be focused on using the AWS cloud technologies.
  • Each week's sessions build off each other and are connected from the first to the last sessions.
  • Organizer will provide homework for a knowledge transfer using discord, youtube live for a communication channel.
  • There are also grading and completion you will earn a digital badge from the boot camp organizer.
  • One requirement you need to Bring your Account or your free tier AWS account, the Domain name that you can access DNS record settings also be able to apply at least two subdomains from the domain name that has been purchased.
  • Done every Saturday at (noon) Toronto Time (UTC-5)
  • Sessions will be recorded and the organizer will post the link for the youtube playlist.

Going over the business use-case of our project?

  • You have been hired as a new Employee on a startup. as a cloud engineer interviewed by a co-founder, you will handle the app project using a microservice that can leverage the decoupling of components so that the app will survive in case of a disaster strike. you ask what are microservices and their benefit from your projects and the Co-Founder tells you about Agility, Easy Deployment, Technological Freedom from other providers, and also flexible scaling.
  • in the sessions organizer also quote the “Iron Triangle” that will give you the quality with proportion to Cost, Time, and Scope. that will affect the project along the way. as a project stakeholder and member.

Note the following during the kickoff meeting with the team.

  • The app is an ephemeral-first micro-blogging platform
  • fractional CTO so less collaboration -partly developed an app - always keep updating
  • how to monetize the platform
  • front end = JS using React
  • Back end
  • python using flask
  • api based only
  • budget constraint -user content upload?
  • target user college students younger students and professionals
  • need user validation
  • need to implement age limit?
  • AWS cloud technologies
  • What services need to run? for microservices it’s Containers?
  • Set up budget Monitoring
  • User Engagement for their user stories on their features request
  • Technical report due needed ASAP by investors
  • Architecture Diagram
  • Budget Allocation
  • Operational Expenses or OPEX

Looking at an architectural diagram of what we plan to build

  • first considered AWS's well-architected framework
  • Operational Excellence
  • Security Pillar
  • Reliability Pillar
  • Performance Efficiency
  • Cost Optimization
  • Sustainability

Using Lucid charts architecture diagram

Use of C4 models

  • use as an architect tool for creating a viable product 
  • Has 4 categories, System Context, Containers, Component, and Code;
  • System Context - starting points and talks about how the system will fit in the environment
  • Containers - These were the building blocks of functions of every component 
  • Component -  This is the granular components of every container 
  • Code - This is how components will be implemented 

Running the cloud services we will utilize

  • AWS Services and their free tier components and make sure we got less cost when doing this projects

Testing that we can access our AWS accounts

  • Go to this link https://signin.aws.amazon.com/
  • Login to your account, fill up the username and password
  • root account is powerful that’s why is prohibited to use if not necessary
  • best practice is to create a group and grant administrative IAM policy in that group.
  • and then create a normal or another user and include them in the administrative group.

Track spend in AWS eg. AWS Budgets, AWS Cost Explorer, Billing Alarms.

Understanding how to look at monthly billing reports.

AWS budgets
