Presentation shows how current Cloud looks like and how it will evolve with serverless technologies such as AWS Lambda, API Gateway and CloudFront. Do we need servers? Do we need regions? No.

1. Future of Cloud starts with
Serverless

2. What is Droplr?
Screen Capture, File Sharing, Team Collaboration
Used by...
Droplr in numbers:
+ 500k users
+ 50M files (70 TB) in AWS S3

19. Serverless Revolution
Bare metal IaaS
PaaS
Serverless
FaaS

20. Serverless Revolution
AWS Lambda - run code without thinking about underlying
infrastructure
1. Crazy cheap
2. Multiple programming languages support
3. Highly-Scalable
4. Reliable
5. Fast

21. Serverless Revolution
AWS Lambda - run code without thinking about underlying
infrastructure
1. Crazy cheap
Free Tier: 1M requests per month & 400,000/GB-sec
Above: $0.0000002/request + $0.00001667/GB-sec

22. Serverless Revolution
AWS Lambda - run code without thinking about underlying
infrastructure
2. Multiple programming languages support: Node.js
(JavaScript), Python, Java (Java 8), C# (.NET Core), Go
(from 15.01.2018)
$ npm install serverless -g
$ serverless create --template hello-world
$ serverless deploy

23. Serverless Revolution
AWS Lambda - run code without thinking about underlying
infrastructure
3. Highly-Scalable out of the box
Default limit: 1,000 concurrent executions
Our Benchmark: 800 req/s per Node.js function

24. Serverless Revolution
AWS Lambda - run code without thinking about underlying
infrastructure
4. Reliable
100% uptime
in our Pingdom from start (7 months)

25. Serverless Revolution
AWS Lambda - run code without thinking about underlying
infrastructure
5. Fast
<1 ms
for Node.js Express “Hello World”

26. AWS Lambda invocation
SNS
Time
HTTP

27. AWS Lambda use cases
1. Full Node.js/Express API for React SPA
2. Server Side Rendering (why not?)
3. Image processing (e.g. thumbnails)
4. Log Analysis
5. Scheduled maintenance tasks (e.g. database backup)

28. Imagine there
are no regions

29. Moving towards real Cloud
1. Cloud with single region? What about running application nearer
your clients? Maybe in...

33. Result?

34. Thanks
Time for discussion :-)
- Serverless as a game-changer?
- Your ideas of using Serverless?
- Btw. Senior JavaScript/React Developer wanted! ;-)
