benefits of cloud computing

global infrastrucuture

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

---

Databases

RDS relational database service (aurora, postgres, mysql, mariadb, oracledb, sql server)

DynamoDB nosql

ElastiCache in-memory cache

...

---

Networking

VPC virtual private cloud

Security Groups

NACL network access control lists

Route 53
