• AWS
  • DynamoDb - no sql low latency database (used heavily)
    • tables, items & attributes
    • primary keys (simple & composite)
    • secondary indexes (local & global)
    • capacity (RCU/WCU & billing)
    • single-item actions
    • multi-item actions
    • streams
  • Kinesis data streams (similar to Kafka - streaming vs queueing)
    • Summarised Kafka vs queues
  • API Gateway (central api for services with websocks app for auth)
    • Auth
    • Lambda, Cognito, IAM
    • API Keys (rate limiting)
    • Method Requests (Primarily for Validation)
      • RequestValidator -> Method (simple param/header)
      • Model -> Method -> RequestValidator (request body)
    • Integration Requests (data transformation)
      • Proxies
        • proxy resource (binding from route)
        • proxy integrations (template free forwading)
        • service proxy (forward to AWS service)
      • VTL
      • Passthrough
    • Errors
      • type/status/params/templates
      • minor customisation (codes, details, not full VTL)
    • Integration Responses
      • Lambda/HTTP proxy should provide in required format
      • regex matching for messages/status (depending on source)
      • VTL templates
    • Method Responses
      • Lambda/HTTP proxy n/a again
      • only has 200 OK by default
      • method response must exist to use code in integration response
      • allows for Models useful for SDK (strongly-type langs)
    • documentation & publishing (used?)
  • Lambda (compute power for intermittent applications)
  • CloudFormation (provisioning - infrastructure as code - used heavily)
  • SQS
  • ECS (used with EC2 to roll out Docker based services)
  • Cloudwatch - (all logging but also some metrics)
  • S3
  • Route 53 (not critical but no harm in knowing)
• NodeJS (brushup)
• Typescript (ES10/ES2019)
• Yarn (brushup + TS Compilation)
• React (TS)
