    Study Notes

    Elastic Container Registry(ECR)

    • ECR is a private Docker registry on AWS
    • It allows you to store Docker images for use with ECS or Fargate

    Serverless

    • Serverless is a new paradigm that allows developers to deploy code and functions without managing servers
    • Initially, serverless was synonymous with FaaS (Function as a Service)
    • AWS Lambda pioneered the serverless concept
    • Serverless includes managed services like databases, messaging, and storage
    • Serverless doesn't mean there are no servers, but rather that you don't manage, provision, or see them

    AWS Lambda

    • AWS Lambda is a serverless compute service
    • It runs functions on demand, scaling automatically
    • Lambda offers high performance optimized for specific data models
    • Lambda functions have short execution times (limited by time)
    • Lambda functions have limited resources: RAM and CPU
    • Lambda is more flexible and scalable than Amazon EC2
