Spring Boot makes creating small Java application easy - and also facilitates operations and deployment. But for Microservices need more: Because Microservices are a distributed systems issues like Service Discovery or Load Balancing must be solved. Spring Cloud adds those capabilities to Spring Boot using e.g. the Netflix stack. This talks covers Spring Boot and Spring Cloud and shows how these technologies can be used to create a complete Microservices environment.
Understanding MicroSERVICE Architecture with Java & Spring BootKashif Ali Siddiqui
This is a deep journey into the realm of "microservice architecture", and in that I will try to cover each inch of it, but with a fixed tech stack of Java with Spring Cloud. Hence in the end, you will be get know each and every aspect of this distributed design, and will develop an understanding of each and every concern regarding distributed system construct.
Microservice With Spring Boot and Spring CloudEberhard Wolff
Spring Boot and Spring Cloud are an ideal foundation for creating Microservices based on Java. This presentation explains basic concepts of these libraries.
This talk introduces Spring's REST stack - Spring MVC, Spring HATEOAS, Spring Data REST, Spring Security OAuth and Spring Social - while refining an API to move higher up the Richardson maturity model

The java persistence API provides a specification for persisting, reading, and managing data from your java object to your relational tables in the database. JPA specifies the set of rules and guidelines for developing interfaces that follow standards.
Welcome to presentation on Spring boot which is really great and relatively a new project from Spring.io. Its aim is to simplify creating new spring framework based projects and unify their configurations by applying some conventions. This convention over configuration is already successfully applied in so called modern web based frameworks like Grails, Django, Play framework, Rails etc.
A introduction to Microservices Architecture: definition, characterstics, framworks, success stories. It contains a demo about implementation of microservices with Spring Boot, Spring cloud an Eureka.
Four Times Microservices - REST, Kubernetes, UI Integration, AsyncEberhard Wolff
How you can build microservices:
- REST with the Netflix stack (Eureka for Service Discovery, Ribbon for Load Balancing, Hystrix for Resilience, Zuul for Routing)
- REST with Consul for Services Discovery
- REST with Kubernetes
- UI integration with ESI (Edge Side Includes)
- UI integration on the client with JavaScript
- Async with Apache Kafka
- Async with HTTP + Atom

In this tech talk, Rick Evans will introduce Spring BlazeDS Integration.
Spring BlazeDS Integration is a Spring Portfolio project that makes it easier to build Rich Internet Applications for the enterprise using Flex and Spring. Integrating the powerful remoting and messaging features of Adobe BlazeDS with the familiar Spring programming model, Spring BlazeDS Integration is a great jumping-on point for Java developers looking to front Spring-based server-side enterprise applications with rich and polished Flex front-ends on the client.
Some previous exposure to Spring and Flex is best if you want to get maximum benefit from the talk.
Infrastructure for Continuous Delivery & Microservices: PaaS or Docker?Eberhard Wolff

Limiting software architecture to the traditional ideas is not enough for today's challenges. This presentation shows additional tools and how problems like maintainability, reliability and usability can be solved.
Continuous Delivery solves many current challenges - but still adoption is limited. This talks shows reasons for this and how to overcome these problems.
There are many different deployment options - package managers, tools like Chef or Puppet, PaaS and orchestration tools. This presentation give an overview of these tools and approaches like idempotent installation or immutable server.

Microservices and Self-contained System to Scale AgileEberhard Wolff
Architectures like Microservices and Self-contained Systems provide a way to support agile processes and scale them. Held at JUG Saxony Day 2016 in Dresden.
Data Architecturen Not Just for MicroservicesEberhard Wolff
Microservices change the way data is handled and stored. This presentation shows how Bounded Context, Events, Event Sourcing and CQRS provide new approaches to handle data.
We assume software should contain no redundancies and that a clean architecture is the way to a maintainable system. Microservices challenge these assumptions. Keynote from Entwicklertage 2016 in Karlsruhe.
Nanoservices are smaller than Microservices. This presentation shows how technologies like Amazon Lambda, OSGi and Java EE can be used to enable such small services.
Microservices: Architecture to scale AgileEberhard Wolff
Microservices allow for scaling agile processes. This presentation shows what Microservices are, what agility is and introduces Self-contained Systems (SCS). Finally, it shows how SCS can help to scale agile processes.
Microservices, DevOps, Continuous Delivery – More Than Three BuzzwordsEberhard Wolff

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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.
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).

Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

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!
