Swift Runtime in IBM Bluemix
• Runtime leverages the Cloud Foundry open source
swift-buildpack
• Bluemix steps:
• provide access to a Linux container
• load the latest Swift binaries
• issue a command to build your application via
Swift.org’s Package Manager
• run your built application
• make your running application available via a
public URL.

Kitura
• Lightweight web framework
• Build web services with complex routes
• Simplify app deployment
• Open-sourced on Github under an
Apache 2.0 license

12. IBM Bluemix OpenWhisk
The Future of Cloud Programming:
Wiring a Microservices Application Architecture to Respond to Events

13. Meet Dave, the developer
• Spend time on business
logic that adds value to
my company
13
• Spend time on low-level
infrastructural and
operational details
I want to… I don’t want to…
• Easily consume services
• Pay only for resources my
apps use
• Configure and manage
accesses to services
• Pay for resources my
apps don’t use

14. Whisk in a nutshell
“Event-action platform to execute code in response to events“

15. OpenWhisk: Another way to build apps…
Build your apps, your way.
Use a combination of the most prominent open-source compute technologies
to power your apps. Then, let Bluemix handle the rest.
Ease of getting started Full stack Control
OpenWhisk
Event-driven apps,
deployed in a serverless
environment.
Instant Runtimes
App-centric runtime
environments based on
Cloud Foundry.
IBM Containers
Portable and consistent
delivery of your app
without having to manage
an OS.
Virtual Machines
Get the most flexibility
and control over your
environment with VMs.

16. Whisk in a nutshell
Serverless deployment & operations model
We hide infrastructural and operational complexity allowing you to focus on coding:
You provide code – we execute it!
Optimal utilization, fair pricing at any scale
We provide you exactly with the resources you need – neither less nor more - and charge
you only for code really being executed
Flexible programming model & powerful tooling
We support multiple languages (incl. Swift) and even the execution of custom logic via
docker containers plus tools to declaratively chain your code snippets
Open & open ecosysten
Open to run anywhere to avoid any kind of vendor lock-in and to accelerate the
development of a powerful ecosystem

17. OpenWhisk: How does it work?

Event Providers
OpenWhisk
Cloudant
Git
Weather
…
…
Data event occurs, e.g.
-Commit on a Git Repository
-CRUD operation on Cloudant
-….
Trigger execution
of associated
OpenWhisk action
2
…
JS Swift Docker …

18. High-level
Architecture
Triggers: A class of events emitted by
event sources.
Actions: Encapsulate the actual code
to be executed which support multiple
language bindings. Actions invoke any
part of an open ecosystem.
Rules: An association between a
trigger and an action.
Packages: Describe external services
in a uniform manner.
Combined these allow developers to
compose solutions using modern
abstraction and chaining which can be
created, accessed, updated and
deleted via the CLI
OpenWhisk provides a distributed compute service to
execute application logic in response to events.

19. Programming model
Trigger: “A class of events that can happen“T

20. Programming model
Actions: “An event-handler, i.e. code that runs in response to an event“A

21. Programming model
Actions: Multi-runtime support, e.g. JavaScriptA
function main(msg) {
return { message: 'Hello, ' + msg.name + ' from ' + msg.place };
};

22. Programming model
Actions: Multi-runtime support, e.g. SwiftA
func main(params:[String:Any]) -> [String:Any] {
var reply = [String:Any] ()
if let name = params[“name”] as? String {
print(“Hello (name)”)
reply[“msg”] = “Goodbye (name)”
}
return reply
}

23. Programming model
Actions: Multi-runtime support, e.g. Docker containersA

24. Programming model
Actions: Can be chained to create sequences to increase flexibility and
foster reuse
A
AA
:= A1
+ A2
+ A3
AB := A2
+ A1
+ A3
AC
:= A3
+ A1
+ A2

25. Programming model
Rules: “An association of a trigger and an action“R
R := T A

26. Programming model
Packages: “A shared collection of triggers and actions“P

– allows you to outsource load & calculation intensive tasks
– only charges you for what you really use
– is available as open solution in which you can participate

30. Blockchain / Hyperledger
30

31. Introducing Blockchain
A shared ledger technology allowing any participant in
the business network to see THE system of record
(ledger)

32. Blockchain underpins Bitcoin . . .
• bitcoin: unregulated, censorship-resistant
shadow currency
• bitcoin: first Blockchain application
• pioneer of Blockchain technology
• BUT Blockchain is not bitcoin
Digital currencies different from cryptocurrency

33. Ledgers are key . . .
• Ledger is THE system of record for a
business
• Business will have multiple ledgers
for multiple business networks in
which they participate.
• Transaction - an asset transfer onto
of off the ledger
– John gives a car to Anthony (simple)
• Contract - conditions for transaction
to occur
– If Anthony pays John money, then car
passes from John to Anthony (simple)
– If car won't start, funds do not pass to
John (as decided by third party
arbitrator) (more complex)

34. Problem - Difficult to monitor asset ownership and transfers in a trusted
business network

same as before

36. Blockchain for Business
Smart
Contract
Privacy
Shared
Ledger
Consensus
Ensuring appropriate
visibility; transactions are
secure, authenticated &
verifiable
Business terms embedded
in transaction database &
executed with transactions
All parties agree to
network verified
transaction
Append-only distributed
system of record shared
across business network
Broader participation, lower cost, increased efficiency

37. Blockchain Benefits
Saves Removes Reduces
Time Cost Risk
Transaction time
from days to near
instantaneous
Overheads and
cost intermediaries
Tampering, fraud &
cyber crime

38. Not for all . . .
Blockchain is NOT
Suited to high performance
(millisecond) transactions
For just one participant (no business
network)
A replicated database replacement
A messaging solution
A transaction processing replacement
Suited for low value, high volume
transactions

39. Hyperledger Project
39
 Linux Foundation - announced 17th December 2015
 New Hyperledger project to transform the way business
transactions are conducted around the world
 Project members understand that an open source, collaborative
development strategy supporting multiple players in multiple
industries is required
Enable adoption of shared ledger technology at a pace and depth not
achievable by any one company or industry
