Route 53

• DNS

[[AWS S3]]

EC2

• virtual machine

EC2 vs LightSail

• Lightsail is like Digital Ocean's $5/month
• EC2 can have more bad-ass servers
  • these servers are more temporary

ECS

• basically a lightweight Kubernetes?
  • where you manage some EC2 instances

Fargate

• level of abstraction that's higher than ECS
• idea of tasks which could be a group of EC2 instances

WAF

• Web Application Firewall
  • protects all AWS services
  • not just the frontend
• we used to use Sqreen
  • got bought by Datadog
  • they jacked up the price

Kinetic

• like Apache Kafka
• for streaming content like logs or videos
  • example: sending logs to DataDog

Bastion Host

• Machine in the Virtual Private Cloud (VPC)
• always running
  • unlike EC2 instances
• lets you port forward or ssh into EC2 instances easily

AWS ECS

ECS vs Kubernetes

• ECS is like simple Kubernetes for EC2 only clusters
• ECS orchestrates docker containers on EC2 clusters
• ECS manages a lot for you so it's simpler than Kubernetes
• Kubernetes is portable
  • if you want to move to Azure, GCP

AWS Fargate vs AWS ECS

ECS manages EC2 instances

Fargate is a level of abstraction higher

You manage tasks (2+ containers working together like backend and frontend container) 

Containers in the same task can communicate with each other via localhost

AWS Elasticache is used to host Redis

AWS Code Artifacts for databricks????

AWS CloudWatch
