Model: 4 benefits of cloud computing

agility: innovate faster elasticity: no need to overprovision cost savings: trade capital expenses for variable expenses deploy globally in minutes

---

global infrastrucuture

Region -> AvailabilityZone AZs within region - high speed connection between AZs

local zones: close to large population centers wavelength zones: embed within 5g networks direct connect: links network directly to AWS, bypassing the internet cloudfront: edge locations + regional edge caches

1. Compute EC2 Elastic Compute Cloud EC2-auto-scaling ELB Elastic Load Balancing ECS Elastic Container Service EKS Elastic Kubernetes Service Lambda

Befits of EC2 elasticity: scale up and down depending on demand control: root access flexibility: instance types, OS integrated with other AWS services reliable: high available secure cost-effective easy to get started: web console, cli, sdk

instance types general categories -> families -> generation -> size accelerated computing: hardware accelerators storage optimized

AMI Amazon Machine Images -amazon provided -marketplace -community -custom: create & maintain

scalable on-demand architecture EC2-auto-scaling-group desired? what does it do?

ELB elastic load balance app LB: network LB: more resilient to spikes gateway LB: for third party marketplace

2. Storage EBS elastic block store S3 simple storage service S3-glacier: backup / archive Storage Gateway: on-premise <> cloud EFS elastic file system FSx (netapp, openzvs, windows file server, luster)

EBS ? shared storage for all instances?

S3

S3-standard S3-standard-IA infrequent access S3-one-zone-IA infrequent access S3-glacier - a. instant retrieval - b. flexible retrieval - c. deep archive

S3-Intelligent-Tiering: automatic switching
