15. COMPUTE
    Functions are the unit of deployment and scaling.
    No machines, VMs, or containers visible in the
    programming model.
    Permanent storage lives elsewhere.
    Scales per request;
    Users cannot over- or under-provision capacity.
    Never pay for idle
    (no cold servers/containers or their costs).
    Implicitly fault-tolerant because functions can run
    anywhere.
    BYOC - Bring Your Own Code.
    Metrics and logging are a universal right.

    Event Driven
    JVM-based languages (Java 8),
    JavaScript (Node.js),
    Python, C#, (more to come)
    Versions, Encrypted Environment Variables,
    Step Functions
    Pay as you use - in 100ms blocks
    (e.g. 100ms w/ 128MB memory = USD 0.000000208)

22. GATEWAY
    "Reverse Proxy"
    hides possible multiple service calls
    (aka "service composition", ESB?)
    distributes requests to proper service instances
    "Mock" services
    Authentication / Authorization
    Caching, Throttling, DDoS attack protection, etc.
    API

    Schemaless Data Model
    DynamoDB Streams
    Record TTL
    Seamless Scalabiltiy, "no limits"
    Pay by Read-/Write-Capacity-Units
    and used storage, not by time
    DB
