The document discusses the evolution of event-driven architectures. It notes that while event-driven concepts have long existed, they became more prominent in control engineering applications involving sensors. Modern architectures like SOA and BPM benefit from incorporating event-driven design to better handle interdependencies between systems. Early frameworks like CORBA aimed to facilitate interoperability but had inherent limitations that newer approaches address.
Event-driven architecture (EDA) is a software architecture pattern promoting the production, detection, consumption of, and reaction to events.
This architectural pattern may be applied by the design and implementation of applications and systems which transmit events among loosely coupled software components and services.
In this session you’ll learn how to create a loosely coupled architecture for your business that has the domain at the core. You’ll learn the basics of EDA, and also learn how we are transforming our architecture at Unibet.com to become event driven, and what benefits it will bring to our business. The session will cover technologies such as JMS, XML, JSON, Google Protocol Buffers, ActiveMQ and Spring.
In this presentation, I will explain event driven architecture, describe the different types of events, demonstrate how events can be related and orchestrated, and provide a basic understanding of how this method can drive the architecture of enterprise systems. In addition to understanding the concepts of event driven architecture, we will explore a working sample built using an open-source .NET messaging framework called MassTransit.
Overview of SaaS and online services and the business reasons why organisations should be considering these. Delivered by Ben Kepes at Intergen's ON seminar series in May 2010.

Event-Based Business Architecture: Orchestrating Enterprise Communications confluent
(Gary Samuelson, GarySamuelson) Kafka Summit SF 2018
A business-oriented view, illustrating both process models and in-flight task progress, is critical to understanding organizational health, efficiency and alignment to strategic goals. The intent of this talk is to illustrate the real-time relationship between Kafka-managed events (event driven) and business architecture via actionable models (real-time analytics).
Takeaways:
-Understand how business views technology in terms of capabilities aligned to strategy.
-Introduce process model and performance views into an event-oriented dashboard. This view illustrates the organization in terms of collaborating human and automated services.
-Illustrate how system architecture dovetails into business goals with an aligned business/IT architectures.

Webinar: Monitoring & Orchestrating Your Microservices Landscape using Workfl...camunda services GmbH
A company’s core business processes nearly always span more than one microservice. In an e-commerce company, for example, a “customer order” might involve different services for payments, inventory, shipping and more. But how do these services play together to fulfill the customer’s desire?
Implementing long-running, asynchronous, and complex collaborations between distributed microservices is challenging. How can we ensure visibility of cross-microservice flows and provide status and error monitoring? How do we guarantee that overall flows always complete, even if single services fail? Or how do we recognize stuck flows so that we can fix them?
In this webinar, Bernd will explain how workflow automation supports the orchestration of microservices, to make sure business processes are always carried out - even in case of failure -
providing monitoring and visibility into the overall progress and status.
He will reveal how to do all of this without introducing monolithic workflows that clash with microservices principles. You will also learn how to balance orchestration (using a workflow engine) with choreography (using events). Still believe that choreography is more loosely coupled and thus the modern way to go? You definitely need to listen in…

Cloud Service Management: Why Machine Learning is Now EssentialDevOps.com
You know that workloads, organizations, culture and process are impacted by the successful transition to cloud. When DevOps/Lean replaces ITIL, traditional IT service management must transform to remain relevant. Infrastructure ops must stop thinking of themselves as the "center of the universe" and start thinking of themselves as a "skilled service organization" for multiple DevOps teams. Indeed, site reliability engineering (SRE) has emerged, with a greater focus on automation to operate the cloud in a scalable way.
Join Sinead Glynn and Jim Carey as they explain why IBM believes adaptive automation, delivered through innovative machine learning, is now essential to achieve cloud service management at scale.

Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
2. • Event driven is nothing new. It has existed ever
since computing began. But then the emphasis
was not architectural.
• As the technologies advanced; especially in the
control engineering where ‘sensors’ based
application is prevalent; Event driven design
became a paradigm.
• The ferocity of the competition in the market
has created a greater need for
interdependencies among the systems. Event
Driven Architectures, complementing SOA &
BPM ensures to achieve such a system.
3. 1989 – OMG was Born
• To facilitate interdependencies among the
businesses architectural frameworks were
sought; such as ‘Common Object Request Broker
Architecture’.
• The motive then was to promote object oriented programming and
distributed architecture to achieve greater functional
interdependencies.
• However, the functions still remained quite tightly coupled in
most cases.
4. 2001 – Model Driven Architecture Introduced
• Motive was to achieve
– a better holistic design,
– while promoting better use of strong
notation (UML)
– better ‘separation of concerns’
– Platform Independent Model
– Platform Specific Model
– model transformation and engineering
change management
• This addressed better design management, but the
inherent problems that were in CORBA did not go away.
Although some loose coupling occurred.
5. • As software architectures evolved, the designs moved
from hardware into software.
• Telecom is a classic example. The architecture that was
tightly coupled to the hardware gradually moved the
management functions embedded in the hardware into
the software.
• Almost all the embedded engineering is ‘event
dependent’. This means a paradigm shift in the
software architecture approach to incorporate the
functions migrated from the hardware.
6. During late 2000s
• SOA has taken center seat..
– SOA relies on
• Loose Coupling
• Coarse Grain
• This means the atomic structure of the
‘services’ is lot more larger than the object
oriented ‘function’
• Furthermore, the services are brought together
to instantiate business processes by another
component - ‘orchestration’.
• The design of the ‘orchestration’ layer creates a
greater need for an architecture that is ‘event
driven’ such that this layer is service/function
independent.
7. • To achieve a coherent model, the event driven design
paradigm requires being shifted from the level of services
into the orchestration component of the architecture
framework. This requires creating another layer called
‘Enterprise Service Bus’
• The ESB concept is a new approach to integration that can
provide the underpinnings for a loosely coupled, highly
distributed integration network that can scale beyond the
limits of a hub-and-spoke EAI broker.
Ref: David Chappell
• An ESB is a standards-based integration platform
that combines
•messaging
•web services
•data transformation and
•intelligent routing
to reliably connect and coordinate the interaction of
significant numbers of diverse applications across
extended enterprises with transactional integrity.
8. What are Services
• Services are request/response mechanisms.
• A service consumer makes a request and a service provides a response.
Essentially, a service consumer calls the service operation of a service and
the information flows through the service interface. Then the service
implementation processes the request and provides the information to the
service interface that responds.
9. • When Services do not act as requesters
but instead Events trigger a complex array of
interdependent business processes to respond
to a condition, the design paradigm shifts to :
Event Driven Architecture (EDA)
• In an EDA, a complex array of
business processes turns into a
non-hierarchical net-centric
structure
10. • While EDA is fundamentally different from SOA,
the two styles are not contradictory and, in fact,
they work together well.
• EDA is a request/response architecture
• Service consumers make requests of services
and wait for responses
• The idea of EDA is quot;fire and forget.quot; Systems are
constructed to respond to events that occur in
software or in the real world.
• Once an event has occurred, a cascading
process begins in reaction to the event.
