‫So, let's talk about the actual last pillar
‫in the well architecture framework, which is sustainability.
‫It's a new pillar.
‫So, this pillar focuses on minimizing
‫the environmental impact of running cloud workloads.
‫So the idea is that you want to understand
‫your impact, establish performance indicators,
‫evaluate improvements,
‫make sure you reach sustainability goals.
‫So, find these long terms and find your ROI.
‫Maximize the utilization of your services
‫because you wanna be energy efficient
‫and obviously be environmental conscious.
‫You want to anticipate
‫and adopt new more efficient hardware over time
‫because AWS does some optimizations to their infrastructure
‫and if you use their newer stuff,
‫then you are being more efficient.
‫Use manage services where possible
‫because you share the infrastructure with many people
‫and therefore you are in a better space for sustainability.
‫And reduce the downstream impact of your cloud workloads.
‫So, reduce the amount of energy
‫or resources required for your services
‫and your need for your customers
‫to constantly upgrade their devices.
‫So, some services that help with sustainability in AWS,
‫for example, EC2 Auto Scaling
‫or Serverless Offerings such as Lambda or Fargate.
‫And you want to get basically use
‫the right amount of compute for your task.
‫Cost Explorer; Graviton 2,
‫EC2T type of instances and Spot Instances.
‫All of them allow you to make sure you're energy efficient
‫when using the capacity compute of AWS,
‫and spot instances will allow you to use spare capacity,
‫which will be wasted otherwise.
‫Then some tiering storage,
‫so EFS-IA, Amazon S3 Glacier, Cold HDD for EBS volumes
‫all allow you to optimize your cost regarding storage.
‫Like is all your data needing to be hot,
‫these kind of questions.
‫Then S3 Lifecycle Configurations
‫S3 Intelligent Tiering
‫to make sure your data is in the right tier
‫as well as Amazon Data Lifecycle Manager.
‫And finally, databases can help you,
‫so Read Local, Write Global.
‫So think about RDS Read Replicas,
‫Aurora Global Databases,
‫DynamoDB Global Tables or using CloudFronts.
‫Okay. That's it for this lecture, I hope you liked it.
‫And I will see you in the next lecture.
