var reply = [String:Any] ()
if let name = params[“name”] as? String {
print(“Hello (name)”)

- 13. Meet Dave, thedeveloper • 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 anutshell “Event-action platform to execute code in response to events“
- 15. OpenWhisk: Another wayto 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 anutshell 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 doesit work? } 1 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 classof 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.

- 29. Summary • OpenWhisk… – allowsyou to focus on developing value-adding code – provides you with a flexible programming model for small agile teams – provides you with access to an open ecosystem of building blocks – allows you to compose powerful solutions using modern abstraction and chaining – allows you to share and reuse what you have build – 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

- 31. Introducing Blockchain A sharedledger 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 Counter-party records Bank records PartyC’s Records Auditor records Party B Records Party A’s Records API-integrations Incident Inefficient, expensive, vulnerable Ledger Ledger Ledger Ledger Ledger Ledger
- 35. Solution – shared,replicated, permissioned ledger Counter-party records Bank records Party C’s Records Auditor records Party B Records Party A’s Records Consensus, provenance, immutability, finality Ledger Ledger Ledger Ledger Ledger Ledger Participants have multiple shared ledgers NOTE : Participants same as before
- 36. Blockchain for Business Smart Contract Privacy Shared Ledger Consensus Ensuringappropriate 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 RemovesReduces 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 LinuxFoundation - 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
