Key components of a Blockchain
Smart contracts + ‘key/value’
database with current state
Ledger records
ALL transactions
Distributed Ledger Technology
(acronym: DLT)
Decentralized peer-to-peer
network of nodes
Any transaction added is
validated by multiple entities
Public key-cryptography
without central authority
blockchain == ‘digital trust’

Integration Cloud Updates
Integration:
• Many new features for building complex orchestrations
• New JET mapper – the pain is finally gone! (incl. expression builder)
• Recommendations when building mappings
• Inline menu to add actions (e.g. new For Each loop and AI powered)
• Switch between different layouts
• Local calls to other integrations, no need for connections/adapters
• Build custom adapters in minutes
• Oracle Litmus for unit testing
• Create unit tests and record automatically and play them back
• Recording can be run without the need of endpoints (simulated)
• RPA (Robotic Process Automation) Adapter

What’s Next:
Serverless, FaaS

Serverless is an abstraction of infrastructure and its
operations including provisioning, scaling, patching, etc.
FaaS (Functions-as-a-Service) is the compute
component in a serverless platform

#oowamis
Serverless Computing

#oowamis
Why Serverless?
• Easier: Just think about your code, not infrastructure
• Powerful: Transparent and limitless scaling
• Faster: Deploy faster, iterate faster, innovate faster
• Cheaper: Only pay for what you use to the ms (never idle)

#oowamis
Functions-as-a-Service

#oowamis
The Fn Project
• Independent open-source container-native serverless platform
• Run anywhere: Cloud / Datacenter / Laptop / Raspberry Pi
• Functions are primitive docker containers
• Fn ♥ Java, Go, Javascript (Node.js), Python and Ruby
• Native CloudEvents support
• Will likely contribute to the CNCF (Cloud Native Computing Foundation)
CloudEvents : https://cloudevents.io
CNCF : https://www.cncf.io/
Fn Project : http://fnproject.io/

#oowamis
Fn Flow
• Build reliable and scalable FaaS applications with functions
• Flow functions are written purely in code
• Build distributed applications
• Provides rich concurrency primitives including fork-join, chaining, delays
and error handling

#oowamis
Fn Flow – Example

#oowamis
Native CloudEvents support
• Specification for describing event data in a common way
• Seeks to ease event declaration and delivery across services, platforms, ...
• It’s being incubated within the CNCF
• Contributing stakeholder include: Google, Microsoft, IBM, VMware, SAP,
Oracle, Huawei, Alibaba, Red Hat, Iguazio & more
• Common metadata makes events easier to route, fan out, trace, replay
and generally keep “in flight”.
• More portable, more liquid, easier to transport across environments

What’s included?

Robert van Mölken
What’s Next:
Microservices,
(MicroProfile &
Project Helidon)

#oowamis
• An open-source community specification for Enterprise Java microservices
• A community of individuals, organizations, and vendors collaborating within
an open source (Eclipse) project to bring microservices to the Enterprise
Java community.
• Current implementations:

#oowamis
Eclipse MicroProfile 2.1 (Oct, 2018)

A set of Java libraries for developing microservices

Microservices
• Microframework
• Functional style
• Reactive
• Transparent
• MicroProfile
• Declarative style
• CDI, JAX-RS, JSON-P
• Familiar to Java EE devs
