  • NEW CLOUD APPLICATIONS MODELS

  • SIMPLE PROBLEMS Thumbnail images as they arrive in a bucket Check email addresses stored in DynamoDB

  • 1. Provision a fleet of proxy machines to capture data uploads.

    2. For each upload, enqueue a job to process it. 3. Provision a second fleet of machines to read and

    process jobs. 4. Pick a deployment solution. 5. Plan capacity, accounting for fault tolerance, good

    long-term utilization, burst capability, etc. 6. Monitor 24x7x365 for capacity, health, security, etc. 7. Migrate to new instance types over time, keeping

    OS and language runtimes patched and up to date.

  • WHAT ARE THE PRIMITIVES OF AN APPLICATION?

    Interactions Communicated

    via events

    Functions Data

    The Magic Happens at the Intersection of Functions, Events and Data

    (Pretty much everything else is glue or UI)

  • Driving Data with Events and Functions Composable

    Build small functions, quickly

    Easy to update Add new

    functionality safely and easily

    Dynamic Data is always kept

    up to date

    Why dont we architect like this today? Complex

    Need to manage a full stack for every function

    Expensive Some functions run

    very infrequently

  • AWS LAMBDA STATELESS, EVENT-DRIVEN COMPUTE CODE CALLED LAMBDA FUNCTIONS

  • TRIGGERED BY EVENTS IN OTHER SERVICES

    Put an object in an Amazon S3 bucket Write to a DynamoDB table Message in an Amazon Kinesis stream

  • EVENT-DRIVEN COMPUTING

    AWS LAMBDA IS THE CONNECTIVE TISSUE BETWEEN SERVICES

  • Data Triggers: DynamoDB

    AWS Lambda

    DynamoDB Table and Stream

    Send Amazon SNS notifications

    Update another table

  • Audit and Notify

    AWS API calls

    AWS CloudTrail Logs

    AWS Lambda Bucket events Amazon SNS

    notifications

  • Custom Events

    AWS Lambda

  • Data Triggers: Amazon S3

    Amazon S3 Bucket Events AWS Lambda

  • NO INFRASTRUCTURE TO MANAGE

    Focus on business logic, not infrastructure Upload your code, Amazon Lambda handles:

    Capacity Scaling Fault tolerance Monitoring Logging

  • AUTOMATIC SCALING Each object uploaded to Amazon S3 is an event

    Each event is a Lambda request Lambda scales to match the event rate

    Dont worry about over or under provisioning Pay only for what you use

  • FINE GRAINED PRICING Price compute time by 100ms

    (so even short jobs make sense) Low request charge

    No hourly, daily, or monthly minimums

  • PREVIEW OPEN TO EVERYBODY: AWS.AMAZON.COM / LAMBDA SUPPORT FOR AMAZON S3 AND AMAZON KINESIS
