With AWS Lambda you can easily build scalable microservices for mobile, web, and IoT applications or respond to events from other AWS services without managing infrastructure. In this session you’ll see demonstrations and hear more about newly launched features, as well as a recap of the languages, tools, and features added over the last several months. We’ll show you how to use Lambda to build mobile backends, create web, IoT, and voice-enabled apps, and extend both AWS and third party services by triggering Lambda functions – all without the need for servers or other infrastructure. We’ll also provide productivity and performance tips for getting the most out of your Lambda functions and show how cloud native architectures use Lambda to eliminate “cold servers” and excess capacity without sacrificing scalability or responsiveness.

2. AWS Lambda
A compute service where you
don’t have to think about:
• Servers
• Being over/under capacity
• Deployments
• Scaling and fault tolerance
• OS or language updates
• Metrics and logging
…but where you can easily
• Bring your own code…
even native libraries
• Run code in parallel
• Create backends, event
handlers, and data
processing systems
• Never pay for idle!

11. New Feature: Python 2.7

12. Python 2.7 Support in AWS Lambda
• Available today in
• All SDKs (including mobile SDKs)
• AWS CLI
• Lambda console (including interactive editing)
• Includes
• Version 1.1.3 of boto3 (AWS Python SDK)
• Documentation and walkthroughs
• Console blueprints

13. New Feature: Longer-running Functions

14. Longer-running AWS Lambda Functions
• Run functions for up to 5 minutes
• Available today in the following SDKs
• Python (boto3)
• Java
• Node.js
• PHP
• AWS Mobile SDK for Android
• AWS Mobile SDK for iOS

15. Resource Sizing
• AWS Lambda offers 23 “power levels”
• Higher levels offer more memory and more CPU power
• 128 MB, lowest CPU power
• 1.5 GB, highest CPU power
• Higher power levels == lower latency for CPU-bound
and bursty tasks
• Compute price scales with the power level
• Duration ranging from 100ms to 5 minutes
• Free Tier: 1M free requests and 400,000 GB-s / month

16. New Feature: Scheduled Functions

17. Scheduled AWS Lambda Functions
• Available today in the Lambda console
• Schedule functions at a specific time or recurring
• Accepts standard cron syntax
• 5 minute granularity
• You can get sub-second granularity using a Lambda function
• Easily poll Amazon SQS or other data sources!
• Coming later in 2015: CLI, SDK support

18. New Feature: Versioning

19. Versioning: Development
Developing in AWS Lambda stays simple:
• Upload code
• Make changes any time
• Last update wins
exports.handler =
function(event,context)
{context.succeed(“bye”);}
exports.handler =
function(event,context)
{context.succeed(“hi”);}

20. Versioning: Publishing
Publish new versions from development at any time:
• “Copies” dev version to a numbered version
• Published versions are read-only (including configuration)
• Simple, integer counter per function
exports.handler =
function(event,context)
{context.succeed(“bye”);}
exports.handler =
function(event,context)
{context.succeed(“hi”);}

Versions

21. Versioning: Calling Lambda Functions
Development version:
FunctionName (or)
FunctionName:$LATEST
Specific version:
FunctionName:1
FunctionName:2
Named version:
FunctionName:production
FunctionName:v1_2_3_4

22. Versioning: Aliases
Create named aliases to any version:
• Allows function owner to map ARNs to code
• Can be updated without changing clients
exports.handler =
function(event,context)
{context.succeed(“bye”);}
exports.handler =
function(event,context)
{context.succeed(“hi”);} prod
dev
Aliases

24. New Feature: IoT Backends

25. AWS IoT + AWS Lambda

26. Sneak Peek: VPC Access

27. AWS Lambda VPC Access
• Select the functions to run in your VPC
• Select subnets and security groups to use
• Your Lambda function can access the private resources
you choose:
• Amazon Elasticache
• Amazon RDS
• Private EC2 endpoints
• Any other resources in your VPC
• Launching later this year in all AWS Lambda regions

28. We’ve been busy.
Now it’s your turn.

29. Go to the AWS Lambda console,
create a function, and run it.
(The first million invokes are on us!)

30. Congrats, you’re a Lambda
function expert! Add an event
source or an HTTP endpoint.

31. Build a mobile, voice, or IoT
backend with a few lines of
code. Shazam!

32. Remember to complete
