BPEL is the de-facto standard for modeling executable Web services orchestrations. The XML-based language is used for the definition and execution of business processes, as well as scientific workflows using Web services. WSO2 Business Process Server (WSO2 BPS) and Apache Orchestration Director Engine (ODE) are two WS-BPEL-compliant business process executable workflow engines that support the composition of Web services by orchestrating service interactions.
This tutorial will explore advanced concepts in WS-BPEL 2.0 and extensibility in WSO2 BPS, including:
* Fault handling
* Compensation handling
* Selective, multiple, and concurrent event processing
* Message correlation
* Parallel processing
* An introduction to ODE extensions
* Future improvements with the extensions
Introducing SOA and Oracle SOA Suite 11g for Database ProfessionalsLucas Jellema
This session introduces SOA and the new Oracle SOA Suite 11g to the realm of database professionals from which it sometimes seems so far removed. What are the key SOA concepts and objectives? What is at the heart of Oracle SOA Suite 11g: composite applications, BPEL PM, and the mediator. The session shows how SOA services can be leveraged from the database, from triggers, PL/SQL units, or even SQL and how the database can publish events to the event delivery network. It covers how the SOA infrastructure can access the database, primarily using Oracle Database and Oracle Advanced Queueing adapter and how database developers can help in doing so efficiently. It ends with hints for applying SOA concepts to "normal" database development.
PL/SQL developers (as well as DBAs and many others involved) typically are uncertain what SOA means to them. They feel overwhelmed by a avalanche of acronyms. Yet they see it coming and instead of being surprised or bypassed, this session allows them to start participating and benefiting themselves. This session introduces SOA and the Oracle SOA Suite 11g to the realm of the PL/SQL developer - from which it sometimes seems so far removed. What are the key SOA concepts and objectives - what's the buzz about? What is at the heart of SOA Suite 11g: Composite Applications, BPEL PM and the Mediator.
The presentation demonstrates how SOA Services can be leveraged from the database – from Triggers and PL/SQL applications and how the database can publish events to the Event Delivery Network. It demonstrates how the SOA infrastructure can access the database, primarily using the Database Adapter – and how database developers can be instrumental in efficiently doing so. It concludes with some hints for applying SOA concepts for 'normal' database development.
Where and when to use the Oracle Service Bus (OSB)Guido Schmutz
The Oracle Service Bus (OSB) is part of the Oracle SOA Suite 11g and stands in the center of modern process- and integration-solutions. The lightweight, stateless and high-performant architcture of the OSB turns it into an excellent tool for doing transformation and routing of messages. This presentation explains where and when the usage of the OSB makes sense but also shows the limits of the OSB.

Event Sourcing, Domain Driven Design, and Command Query Responsibility Segregation – we hear all of these technologies used together frequently, but how do they actually work together? How do you manage complex co-ordination in a CQRS system?
In this talk, we will discuss a real world example of DDD with ES and CQRS written in F# - a functional first language on the .NET Framework. We’ll take a deep dive into the F# algebraic type system that constructs the domain model. Also, the explanation of the abstract notion of a DDD aggregate root compared to the CQRS implementation of an aggregate root. Finishing with how sagas and triggers facilitate poly-aggregate communication.
Implementing advanced integration patterns with WSO2 ESBWSO2
Enterprise Integration is a means of linking the different components of an SOA system. The success of an SOA solution heavily depends on proper enterprise integration. However this is easier said than done. There are many complex requirements to this process one of which is the need to interconnect heterogeneous systems which use different message formats and protocols and these systems needs to work together to achieve the final outcome
WinOps Conf 2016 - Michael Greene - Release PipelinesWinOps Conf
There are benefits to be gained when patterns and practices from developer techniques are applied to operations. Notably, a fully automated solution where infrastructure is managed as code and all changes are automatically validated before reaching production. This is a process shift that is recognized among industry innovators. For organizations already leveraging these processes, it should be clear how to leverage Microsoft platforms. For organizations that are new to the topic, it should be clear how to bring this process to your environment and what it means to your organizational culture. This presentation explains the components of a Release Pipeline for configuration as code, the value to operations, and solutions that are used when designing a new Release Pipeline architecture.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
2. Overview
• What is BPEL
• WSO2 Business Process Server
• Introduction to BPEL
• HelloWorld Sample
• Advanced Concepts of BPEL
• Fault Handling
• Compensation Handling
• Correlation and Async processes
• Extending WSO2 BPS
3. What is BPEL
• An OASIS standard executable language for
business processes
• More or less a service composition language
• Enables composition of (business) services into
business processes
• XML based language
4. Why Automate Business Processes
• Increase Efficiency
• No need to worry about the coordination of the
process
• Improve Responsiveness
• Business processes are agile
• Improve the process
• Adapt to the change of business needs
5. Business Process wrt BPEL
Business Process is a collection of coordinated
service invocations and related activities that
produce a result, either within a single organization
or across several organizations
6. Why BPEL
• Agility
• No need to worry about low level programming stuff.
• Native support for long running processes
• Compose larger business processes out of smaller
processes and services
• Handle message-related and time-related events
• Industry standard language for expressing
business processes
• Leverage common skill set
7. Why BPEL
• Portability
• Managed execution
• Monitor the progress of the process
• Start, stop, suspend, resume process instance
8. WSO2 Business Process Server
• Executes business processes written using WS-
BPEL standard
• Powered by Apache ODE
• Provide a web-based management console
• Deploy processes
• Manage and view business processes
• Manage and view process instances
• Configure QoS and many more…
9. Why WSO2 BPS
• WSO2 Carbon Studio – BPEL Editor
• Drag and drop process modeler
• Native BPEL support
• XPath editor
• Deploy processes to WSO2 BPS
• Support both BPEL4WS 1.1 and WS-BPEL 2.0
• Graphical Management Console to:
• Deploy and manage business processes
• Manage and monitor process instances
• Configure QoS perameters
10. Why WSO2 BPS

• Support XQuery and Xpath, XSLT
• Support BPEL Extensions
• Features from WSO2 Carbon
11. Want to implement Business Processes?
• What you should already know
• XML
• XML Namespaces
• XML Schema
• WSDL
• XPath
• XSLT and XQuery (optional)
12. Introduction to BPEL
• BPEL Concepts
• Activities
• Basic Activities
• Structured Activities
• HelloWorld sample process
16. PartnerLinkType
• Characterizes the conversational relationship
between two services
• Define the roles played by each of the services in
the conversation
<plnk:partnerLinkType name="BuyerSellerLink">
<plnk:role name="Buyer" portType="buy:BuyerPortType" />
<plnk:role name="Seller" portType="sell:SellerPortType" />
</plnk:partnerLinkType>
17. PartnerLynkType
Buyer Seller Buyer Seller
Invoke Invoke
Seller Seller
Send
response to
Buyer’s
Process Partner Process Partner
Callback
Service Service
Async Sync
18. Partner Link
• Associates with a partnerLinkType
<partnerLinks>
<partnerLink name=“BuyerSellerPL”
partnerLinkType=“BuyerSellerLink”
myRole=“Buyer”
partnerRole=“Seller”/>
</partnerLinks>
• Defines which role should be played by the
process itself and the partner service
19. Variables and Data Manipulation
• Variables
• Statically typed(via WSDL Messages, XSD elements
and XSD types)
• Assigning values to variables
• When message is received from a partner
• Manipulate variables inside <assign> activity
• Require knowledge about XPath, XQuery, XSLT
22. Receive
• Act as the entry point to the business process
• Receives messages from an external partner
• Associated with
• PartnerLink with myRole
• WSDL operation
• Variable for the incoming message
• createInstance="yes" to create a new process
instance, otherwise the incoming message will be
consumed by the (already running) process
instance
23. Reply
• Sends the response back to the client
• Always relates to a “receive” activity
• Associated with
• Same PartnerLink for the “receive”
• Same operation for the “receive”
• Variable for the output message
24. Invoke
• Used to consume partner services
• Associated with
• PartnerLink with at least a “partnerRole”
• WSDL operation of the partner service
• Input variable
• Output variable, if the operation is request-
response
26. Initializing Variables
• Variables contain a piece of XML
• Manipulated using Xpath
• XPath is evaluated on XML
• The variable should be initialized before copying
values to the internal elements.
28. What we got
• String variable “name” – “Waruna”
• Variable “myProfile” – “”
• “myProfile” variable should be initialized before
copying the “name” variable into the “name”
element of “myProfile” variable
• $myProfile/profile/name
29. Initialization
• myProfile =
<profile>
<name></name>
</profile>
• Then copy the “name” into “name” element of
the “myProfile” variable.
• $myProfile/profile/name
41. Fault Handling
• Exceptional condition that can alter the normal
processing of a business process.
• Fault need not result in an immediate process
ending.
• If a fault is not handled, it will lead to
unexpected conditions and outcomes.
• Handle faults, so that failures lead to predictable
outcomes.
43. Catch/CatchAll
• BPEL specific runtime faults
• SOAP faults
• Standard SOAP faults
• Application specific SOAP faults
• After catching a fault
• Try to correct
• Throw a new fault
• Rethrow the fault
• Reply with a fault message
44. Catch/CatchAll
• Handle different types of faults in different ways.
• Multiple catch statements to catch different
types of faults.
• CatchAll activity to handle any type of Fault.
45. Rethrow
• If the current fault handler cannot handle the
fault
• Propagate the fault to an outer-scoped fault
handler
• Available only within a fault handler
46. Throw
• Indicates a problem that a business process flow
cannot handle
• Can be used any where within the process
• Can be thrown
• Standard BPEL faults
• Custom faults
• Variable can be associated to send fault
information
47. Fault Handlers Attached to Invoke Activity
• Handle faults specific to Invoke activity
• SOAP faults
53. Activities for Compensation Handling
• compensationHandler – defines the compensation
logic per each scope
• compensateScope and compensate - used to
trigger the compensationHandler.
55. Asynchronous Invocation
• What Asynchrony is.
• Different asynchronous transport protocols
eg – JMS, SMTP, XMPP
• Modeling asynchronous behavior in WSDLs
eg – by two one-way operations
56. Asynchronous Invocations in BPELs
• Invoke activity to invoke the partner-service
• Receive activity to act as the call-back handler
• So how these two messages get correlated?
57. Message Correlation
• Building block for stateful conversations in BPELs
• Determine to which conversation a message
belongs
58. Message Correlation Sets
• correlationSet - defines the element(s) in
message to act as a unique-id for each message
• correlation - handles the message correlation
between each conversation
60. Extending WSO2 BPS
• BPEL extensions
• Enable to define new BPEL activities
• peopleActivity for BPEL4People
• BPEL event listeners
• Enables to listen to events fired by BPEL engine
• Gather information for BAM
• Message exchange interceptors
• Enables to intercept through the message exchanges
• XPath extensions
