Slides from my NDC Sydney presentation on JavaScript in the cloud - serverless apps, AWS Lambda and why it's important.

1. Awesome JS
microservices
in the cloud for
(almost) free

2. Cloud functions are the most
revolutionary improvement in
clouds since EC2

become at (dev)ops, Amazon*
can do it way better...

13. financial incentive to keep
modules small, isolated and
loosely coupled

14. Lambda is almost free
●
$0.0000002 per request
●
$0.000000834 for 100ms @ 512MB
●
First 1 million requests per month are free

15. execution on tap
●
No need to keep spare capacity
●
No need to worry about failover
●
Pay per actual usage

16. code with batteries included
●
Provisioning + Control
●
Monitoring
●
Task dispatching
●
Balancing
●
Scaling

17. trigger with almost anything
●
File uploads (S3)
●
DB records added (Dynamo)
●
Events in stream (Kinesis, CloudWatch)
●
Workflows (CodeDeploy, SWF, CloudWatch Rules)
●
Scheduled tasks (CloudWatch Events)
●
Message queues (SNS)
●
Web requests (APIGateway)

18. twin business + tech impact
●
Ops by magic
●
Multi-versioning out of the box
●
Small, isolated modules
●
Remove a lot of infrastructure code
●
Testability becomes a challenge

19. functions, not services
●
Five minutes or bust
●
Share nothing
●
No sessions
●
No streams
●
Full utilization = 4-5x dedicated VM price

20. configuration is … problematic
