Taking Your Enterprise to the Next Level with WSO2 Message Broker and WSO2 En...WSO2
In order to cater to the increased demand for reliable and flexible systems, enterprises are leveraging messaging as a solution. In the enterprise integration space, these solutions have evolved into well defined enterprise integration patterns (EIPs). WSO2 Enterprise Service Bus (WSO2 ESB) and WSO2 Message Broker can be used to implement these patterns with ease.
This webinar will discuss how to use WSO2 ESB and WSO2 Message Broker to address the aforementioned needs. The key areas of discussion will include how to
Achieve scalability using point-to-point, publisher/subscriber EIPs and shared subscriptions
Achieve reliability using transactions
Perform request throttling using the store/forward EIP
Integrate between devices in constrained environments (low-bandwidth, unreliable networks, etc.)
Overview of Publish/Subscribe messaging and comparison of MQTT, AMQP and DDS protocols.

This session covers new improvements that will be introduced in WildFly 9:
• Wildfly-core will be extracted from the codebase and the ability to assemble a server on top of it will be introduced. WildFly 9 will be provided in two versions: Wildfly Web and Wildfly Full but users will be able to create their custom packaging of WildFly.
• Users will be able to shutdown the application server in a graceful manner - after the shutdown command is executed server will reject new requests and allow existing requests to finish before it shuts down.
• Support for HTTP/2, a new version of HTTP protocol based on SPDY, will be introduced.
• Users will be able to use WildFly as a load balancer. Consequently, it will be possible to manage the balancer with the same tools that are used to manage the rest of the domain. What is more, users will be able to use more efficient protocols, such as HTTP/2, for communication between the balancer and backend servers.
• An OpenShift cartridge, which will enable users to use WildFly 9 in cloud environment, will be provided.
• WildFly 9 will use OpenJDK ORB library instead of JacORB.
It was year 1999 when EJBoss made it’s debut as an alternative opensource J2EE implementation. 15+ years is more than a lifetime in technology terms and yet the JBoss Application Server project, renamed in 2013 into WildFly has managed to thrive and stay relevant by evolving into the Swiss Army Knife of Application Servers.dandreadis
In this talk we are going to look at the latest developments in WildFly and get an introduction to it’s sister project called WildFly Swarm. WildFly provides a robust, modular, lightweight, fully manageable and fast runtime, implementing the complete set of Java EE7 APIs. WildFly Swarm on the other hand gives you the ability to pick and choose only the server parts you need and bundle them with your application to create fat jars easy to deploy as microservices.
Thus with WildFly & WildFly Swarm you get the richness and maturity of Java EE combined with extreme flexibility about your deployment options in traditional setups or dynamic cloud environments.
Who’s said Java EE needs to be boring?
JMS is known as standard way to implement distributed work with messaging in Java world. There are many JMS providers, both open source and commercial. Large percent of developers use JMS for almost every case when they want to sent message and process it on the other side. But now there are many alternative solutions to organize message queues: AMQP, Redis, ZooKeeper, Apache Kafka or even custom solutions based on Cassandra. Why not to use them instead of JMS? In this talk we will discuss key “issues” in any messaging system and then with this knowledge in mind look once again at JMS and alternative approaches using practical cases from my experience. May be after this talk some more people will stop using JMS and start using their mind. :)

Messaging Connectivity in Hybrid Kubernetes Cloud EnvironmentsDevOps.com
Managing messaging connectivity across applications and data efficiently is a critical component of any hybrid cloud strategy. Whether connecting applications from multiple Software-as-a-Service (SaaS) providers, moving parts of applications to microservices or integrating Kubernetes-based solutions with legacy applications, connectivity is key to ensuring the components of the hybrid ecosystem work together quickly and reliably.
A modern messaging platform should provide complete hybrid infrastructure transparency and support integration at the microservices level. When building an advanced Kubernetes-based technology solution in a hybrid environment, parts of the microservices are deployed in one environment while the rest are deployed in another environment to create a unified solution that takes advantage of the best of both worlds.
In this webinar, we’ll discuss:
Key enterprise considerations when building a Kubernetes-based solution in a hybrid environment on the OpenShift platform
How you can use the KubeMQ platform to enable microservices from multiple environments to communicate with each other
An example from one of our financial services customers
Building Services with WSO2 Microservices Framework for JavaSanjeewa Malalgoda
In this slides we discuss What is Microservice and why we should use it. Also discuss Microservices outer architecture,
WSO2 Microservice movement,
Introduction to WSO2 MSF4J and how we can
develop Microservices with MSF4J(security, metrics etc. )
Making Apache Tomcat Multi-tenant, Elastic and MeteredPaul Fremantle
Are you running Tomcat on the Cloud? What can you do to make Tomcat really take advantage of the cloud? In this session we will discuss how to make Tomcat a native cloud runtime - one that is optimized to run "in" the cloud rather than just "on top" of the cloud. First we will look at what is important for any runtime that wants to truly be cloud native: multi-tenancy, self-service, elasticity, metering and billing, dynamic discovery and side-by-side versioning. Then we will explore how to make Tomcat work in this way. Based on experiences making Tomcat run in a cloud environment as part of Stratos, an Open Source project based on Tomcat and OSGi, we will look at the real issues, solutions, as well as exploring future work in this area.

Microservices created quite a buzz in software development. Those are finally being adopted, and a lot of project suffer from that... microservices bring a lot of infrastructure and distributed programming complexity not all organisations can cope with. Question is – is it possible to gradually migrate to microservices architecture without Big Bang/Rewrite From Scratch approach? I would say it is possible, and is a much better idea compared to installing Kubernetes on AWS on day one. This talk is based on practical experience of architecting business applications to scale out and grow up to become micro services one day.
How to Build Your Own Test Automation Framework?Dmitry Buzdin

Alt. GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using ...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).
Speakers:
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. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

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:
