AWS Well-Architected Framework

Module 9 | AWS Cloud Foundations

AWS WA Tool

Checks out your environment and gives you recommendations to be compliant with best practices and the AWS Well-Architected Framework

The AWS Well-Architected Framework provides a consistent approach to evaluating cloud architectures and guidance to help implement designs

Design Trade-offs

Evaluate trade-offs so you can select an optimal approach.
Examples of trade-offs include the following
- Trade consistency, durability, and space for time and latency to deliver higher performance.
- For new features, prioritize speed to market over cost.
Base design decisions on empirical data

Do you need CloudFront if you don't have customers outside your country?

Implement scalability

Module 10 | AWS Cloud Foundations

Automating your environment

No need for human-interaction to spin up another EC2 instance if this were to occur over night

Infrustructure as Code (IaC)

Use files with code to deploy applications or instances
Rapidly deploy duplicate environments.
Reduce configuration errors from manual configuration.
Propagate changes consistently to all stacks

All someone will have to do is fill in the blanks (IP = ?)

Treating resources as disposable

Automate deployment of new resources with identical configurations
Stop resources that are not in use
Test updates on new resources, and then replace old resources with updated ones

Designing architectures with independent components

Design services, not servers

When appropriate, consider using containers or a serverless solution.
Message queues can handle communication between applications.
Static web assets can be stored off the server, such as on Amazon Simple Storage Service (Amazon S3).
Managed AWS services can handle user authentication and user state storage.

A queue can be used to prevent from applications from crashing when experiencing high workloads (e.g. online store sending orders to a shipping service. Queue in the middle of the two)
