Developing real-time data pipelines with Spring and Kafkamarius_bogoevici
Talk given at the Apache Kafka NYC Meetup, October 20, 2015.
http://www.meetup.com/Apache-Kafka-NYC/events/225697500/
Kafka has emerged as a clear choice for a high-throughput, low latency messaging system that addresses the needs of high-performance streaming applications. The Spring Framework has been, in the last decade, the de-facto standard for developing enterprise Java applications, providing a simple and powerful programming model that allows developers to focus on the business needs, leaving the boilerplate and middleware integration to the framework itself. In fact, it has evolved into a rich and powerful ecosystem, with projects focusing on specific aspects of enterprise software development - like Spring Boot, Spring Data, Spring Integration, Spring XD, Spring Cloud Stream/Data Flow to name just a few.
In this presentation, Marius Bogoevici from the Spring team will take the perspective of the Kafka user, and show, with live demos, how the various projects in the Spring ecosystem address their needs:
- how to build simple data integration applications using Spring Integration Kafka;
- how to build sophisticated data pipelines with Spring XD and Kafka;
- how to build cloud native message-driven microservices using Spring Cloud Stream and Kafka, and how to orchestrate them using Spring Cloud Data Flow;
Watch this talk here: https://www.confluent.io/online-talks/apache-kafka-architecture-and-fundamentals-explained-on-demand
This session explains Apache Kafka’s internal design and architecture. Companies like LinkedIn are now sending more than 1 trillion messages per day to Apache Kafka. Learn about the underlying design in Kafka that leads to such high throughput.
This talk provides a comprehensive overview of Kafka architecture and internal functions, including:
-Topics, partitions and segments
-The commit log and streams
-Brokers and broker replication
-Producer basics
-Consumers, consumer groups and offsets
This session is part 2 of 4 in our Fundamentals for Apache Kafka series.
Traditional approaches to integration testing—using shared, local, or in-memory databases—fall short for today's modern developer.
Developers today are building cloud native distributed microservices and are taking advantage of a rich variety of backing services. This explosion of applications and backing services introduces new challenges in creating the necessary environments for integration testing. To be useful and effective, these environments must be easy to create and they must resemble production as closely as possible. New solutions are needed to make this need a reality.
Enter Testcontainers!
Testcontainers Java is a library that supports JUnit tests and makes it incredibly easy to create lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.
In this talk, you'll learn when and how to use Testcontainers for Java. We'll cover the fundamentals and walk through examples to illustrate various ways you can apply Testcontainers to your applications.

Kafka Tutorial - Introduction to Apache Kafka (Part 1)Jean-Paul Azar
Why is Kafka so fast? Why is Kafka so popular? Why Kafka? This slide deck is a tutorial for the Kafka streaming platform. This slide deck covers Kafka Architecture with some small examples from the command line. Then we expand on this with a multi-server example to demonstrate failover of brokers as well as consumers. Then it goes through some simple Java client examples for a Kafka Producer and a Kafka Consumer. We have also expanded on the Kafka design section and added references. The tutorial covers Avro and the Schema Registry as well as advance Kafka Producers.
Kafka Streams is a new stream processing library natively integrated with Kafka. It has a very low barrier to entry, easy operationalization, and a natural DSL for writing stream processing applications. As such it is the most convenient yet scalable option to analyze, transform, or otherwise process data that is backed by Kafka. We will provide the audience with an overview of Kafka Streams including its design and API, typical use cases, code examples, and an outlook of its upcoming roadmap. We will also compare Kafka Streams' light-weight library approach with heavier, framework-based tools such as Spark Streaming or Storm, which require you to understand and operate a whole different infrastructure for processing real-time data in Kafka.
Quarkus - a next-generation Kubernetes Native Java frameworkSVDevOps
For years, the client-server architecture has been the de-facto standard to build applications. But a major shift happened. The one model rules them all age is over. A new range of applications and architectures has emerged and impacts how code is written and how applications are deployed and executed. HTTP microservices, reactive applications, message-driven microservices, and serverless are now central players in modern systems.
Quarkus has been designed with this new world in mind and provides first-class support for these different paradigms. Developers using the Red Hat build of Quarkus can now choose between deploying natively compiled code or JVM-based code depending on an application’s needs. Natively compiled Quarkus applications are extremely fast and memory-efficient, making Quarkus a great choice for serverless and high-density cloud deployments.

Overview of JMS messaging API.
JMS (Java Messaging Service) is an API for asynchronous message based communication between Java based applications.
JMS implementations (instances that implement the JMS API) are called JMS providers.
JMS defines two messaging domains. Point-to-point queues are typically used between one or multiple message senders and a single message receiver.
Topics are multi-point queues where messages are distributed to multiple receivers. As such topics resemble a black board.
Like many other message oriented middleware technologies, JMS provides advanced functions like persistent message delivery mode or different message acknowledgment modes.
Additionally, messages can be sent and received in a transacted mode thus ensuring that either all or no messages are sent and received.
JMS integrates into EJB (Enterprise Java Beans) through message driven beans.

Patterns are the universal language of architects to communicate, refer, implement and improve. Architecture patterns from traditional SOA (service-oriented architecture) to ROA (resource-oriented architecture) and today to MSA (microservice architecture) drive most enterprise architectures today. Subpatterns such as EDA (event driven architecture) and WOA (web oriented architecture) also has a lot of traction today. These high-level concepts provide many best practices for enterprise architects that are looking to evolve their existing enterprise architecture or for those creating newer enterprise architecture strategies.
However, where should do we draw the line? Is SOA still the way to go or should we focus on MSA? During this session, Asanka will critically analyze the good, the bad and the ugly (if any) of the various architecture patterns, and jointly figure out where they should fit in.

Less Is More: Utilizing Ballerina to Architect a Cloud Data PlatformWSO2
At its core, the challenge of managing Human Resources data is an integration challenge: estimates range from 2-3 HR systems in use at a typical SMB, up to a few dozen systems implemented amongst enterprise HR departments, and these systems seldom integrate seamlessly between themselves. Providing a multi-tenant, cloud-native solution to integrate these hundreds of HR-related systems, normalize their disparate data models and then render that consolidated information for stakeholder decision making has been a substantial undertaking, but one significantly eased by leveraging Ballerina. In this session, we’ll cover:
The overall software architecture for VHR’s Cloud Data Platform
Critical decision points leading to adoption of Ballerina for the CDP
Ballerina’s role in multiple evolutionary steps to the current architecture
Roadmap for the CDP architecture and plans for Ballerina
WSO2’s partnership in bringing continual success for the CD
The integration landscape is changing rapidly with the introduction of technologies like GraphQL, gRPC, stream processing, iPaaS, and platformless. However, not all existing applications and industries can keep up with these new technologies. Certain industries, like manufacturing, logistics, and finance, still rely on well-established EDI-based message formats. Some applications use XML or CSV with file-based communications, while others have strict on premises deployment requirements. This talk focuses on how Ballerina's built-in integration capabilities can bridge the gap between "old" and "new" technologies, modernizing enterprise applications without disrupting business operations.

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!
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

๏ Extensible and Scalable
7. Messaging with MOM
๏ Messaging enables distributed communication that is loosely
coupled
๏ Sender does not need to know about the receiver, nor does the
receiver know anything about the sender
8. What is Java Message Service
(API)
๏ Is an API that allows applications to create, send, receive, and
read messages
๏ Enables communication that is
๏ Loosely coupled
๏ Asynchronous - JMS provider can deliver messages as they
arrive, client does not have to request messages.
๏ Reliable - The JMS API ensures that a message is delivered
once and only once
11. Queue
๏ Facilitates users to store messages sent by an external party, in
an intermediate location and access them on-demand
๏ Enables users to publish messages and receive them in the order
that they are sent
๏ Natively persistent
๏ Even after shutting down the server or if a sudden crash
happens, messages still remain in the queue ready to be
delivered
12. Topic
๏ Every message is delivered to all the subscribers
๏ Non persistent unless durable subscription
13. What is WSO2 Message Broker?
๏ WSO2 MB is a message brokering system based on Java
Messaging Service (JMS).
๏ Any client that supports AMQP is able to communicate with
WSO2 Message Broker
๏ Can be used as a standalone message broker or a distributed
message brokering system.
๏ Uses Apache Cassandra as its message store and Apache
Zookeeper for distributed coordination
๏ Can put message to one MB node in the cluster and pick up the
message from another node MB
16. ESB as JMS Consumer
๏ ESB listens to a JMS queue
๏ JMS client can place a message in JMS queue
๏ ESB picks message from JMS queue and process further
๏ ESB does not need to be active/running to client to produce
messages
17. ESB as JMS Producer
๏ Client sends a message to ESB using synchronous transport like
(HTTP)
๏ ESB puts message to a JMS queue and ack to HTTT client
๏ JMS consumer ( backend ) listens to JMS queue and picks
message
๏ ESB can produce messages to backend regardless of it’s active or
not
18. ESB as both JMS Consumer and
Producer
๏ Combination of previous two patterns
๏ Both ESB and Backend can go offline without breaking message
flow
19. JMS Synchronous Invocations
๏ Client sends a message to ESB using a synchronous transport
(HTTP)
๏ ESB sends a JMS message to request queue with JMSReplyTo
header set to response queue
๏ Backend reads message from request queue and place response
to response queue (by checking JMSReplyTo header)
๏ JMS correlation ID of response = message ID of request
20. JMS Synchronous Invocations
๏ ESB picks matching response from response queue by reading
JMS message which has correct correlation ID (ESB uses a JMS
message selector to perform this)
๏ Finally response if forwarded back to client

21. JMS Synchronous Invocations
(Quad Channel)
๏ Using synchronous JMS invocations in both client and server side
๏ Using synchronous JMS are NOT encouraged because it’s no
longer time decoupled
22. Publish Subscribe with JMS
Client ESB
Topic
๏ Subscribers subscribed to topic in JMS broker
๏ Client sends a message to ESB
๏ ESB forwards message to topic
๏ Message broker delivers message to all subscribers
Subscriber
Subscriber
Subscriber
23. Publish Subscribe Multiple ESBs
Client ESB
Topic
ESB
ESB
ESB
๏ Multiple ESB nodes subscribed to topic in JMS broker
๏ Client sends a message to ESB
๏ ESB forwards message to topic
๏ Message broker delivers message subscribed ESB nodes
24. Message Store and Processor
๏ JMS Message Store
๏ Intermediate persistent storage of messages
๏ A store works with a processor
๏ Message Processor
๏ Sampling processor
๏ Message Forwarding processor
๏ Provides store and forward messaging within the ESB
๏ Can be used to implement
๏ Guaranteed Delivery, Request Rate Matching, In Order
Delivery, and Separation of Concerns
25. Message Store and Processor
Matching Request Rates
๏ Client and Service have two different/varying rate limits for
sending and accepting messages respectively
๏ ESB does rate matching
๏ JMS message store provides Storage
26. Message Store and Processor
Guaranteed Delivery
๏ JMS message store acting as a Dead Letter Channel
27. Message Store and Processor
In-Order Delivery
(3) Send/Retry on
failure
๏ JMS message store acting as a FIFO Queue
28. Message Store and Processor
Separation of Concerns
๏ Most common use of a message store
29. Inbound Endpoint with
Upcoming WSO2 ESB 4.9.0
๏ Create JMS Listeners dynamically without changing axis2.xml and
server restart
๏ Support JMS protocol in tenants
๏ Distributed coordination
๏ Run in all/one node
30. MQTT
๏ MQTT is light weight publish/subscribe protocol
๏ Ideal for mobile devices/IoT because of small footprint
๏ Latest WSO2 ESB supports connecting to MQTT broker
๏ Upcoming WSO2 MB can act as a MQTT broker
31. Apache Kafka
๏ Distributed publish-subscribe messaging system
๏ WSO2 ESB 4.9.0 will support connecting to Apache Kafka
๏ Kafka Inbound endpoint ( consumer )
๏ Kafka Connector ( producer )
