Apache Sling as a Microservices Gateway --- Microservices are definitely the hot topic _du jour_ . Everyone ( and their dog ) is using microservices or migrating towards them. However, there is a gap between the enthusiam for microservices and the ability to create and maintain the infrastructure and culture to effectively use microservices. Apache Sling is an innovative web framework built on top of the Java Content Repository (JCR), that uses OSGi for its component model and fosters RESTful application design. And, as we will see, it is also perfect match for a microservices gateway. In this talk we will review the pros and cons of microservices and monoliths, and look for middle road that smaller organisations that follow to use services productively. One of the approaches we will outline and demo is an API gateway built on top of Apache Sling, used to adress the cross-cutting concerns that would otherwise be reimplemented by all microservices.

Apache Sling is an innovative web framework built on top of the Java Content Repository (JCR), that uses OSGi for its component model and fosters RESTful application design. This talk shows how Sling integrates various standard-based technologies, like OSGi and the Content Repository API for Java to create a coherent framework for web application development. We will walk through the development of a simple application with minimal effort and demonstrate how to productize the resulting application. We will pay special attention to some approaches which are not yet part of mainstream development, such as using OSGi for dependecy injection and JCR for persistence.

Secure by Default Web Applications with Apache Sling

Robert Munteanu

A product that works is not done, as there are many facets to consider – availability, scalability, security. Of those, security is probably the most expensive to get wrong. By analysing a simple web application built on top of Apache Sling and its threat model, we will review the main attack vectors and how they can be mitigated. You will see what the general approaches are and also how Apache Sling allows you to eliminate entire classes of vulnerabilities by using secure-by-default components. Although we will use Apache Sling for examples, previous knowledge of Sling or its components is not required.

Of microservices and microservices

Robert Munteanu

Microservices are definitely the hot topic du jour . Everyone ( and their dog ) is using microservices or migrating towards them. To make things more interesting, the OSGi community has been talking about microservices for 6 years now, so now we have two clashing definitions of the term. Besides the dreaded monolith and the famed microservices-based architecture there is plenty of room for a middle ground, where an API gateway mediates between a host of microservices and their consumers. Such a gateway solves multiple cross-cutting concerns, such as authentication, API standardisation, logging and decoupling the API evolution. As it turns out, OSGi is an ideal setting for building such an application. The API gateway implementation demoed is based on Apache Sling - an innovative web framework built on top of the Java Content Repository (JCR), that uses OSGi for its component model and fosters RESTful application design. Although we will use Apache Sling for examples, previous knowledge of Sling or its components is not required.

Effective Web Application Development with Apache Sling

Robert Munteanu

Do you really want to go fully micro?

Robert Munteanu

Microservices are definitely the hot topic du jour . Everyone ( and their dog ) is using microservices or migrating towards them. However, the initial enthusiasm for microservices is starting to fade, and for many scenarios monoliths still seem to fit the bill. Even more interesting, in many situations a pure approach of using either microservices or monliths is not enough. Instead a more careful, intermediate approach can be quite powerul. This talk introduces the concepst of an API gateway for microservices as a means to adopt microservices at a more convenient pace. This approach brings about most of the benefits of microservices, but removes large chunks of complexity. We will touch upon authentication, authorization, API standardisation and logging, The API gateway implementation demoed is based on Apache Sling - an innovative web framework built on top of the Java Content Repository (JCR), that uses OSGi for its component model and fosters RESTful application design. Although we will use Apache Sling for examples, previous knowledge of Sling or its components is not required.

OSGi for outsiders - Milen Dyankov

mfrancis

OSGi Community Event 2016 Presentation by Milen Dyankov (Liferay) OSGi has evolved and matured beyond recognition over the last few years. It’s now easier than ever before, to build dynamic, modular Java applications to address the challenges imposed by ever growing and constantly changing business requirements. Despite that fact, OSGi seems to be far from receiving the appreciation it deserves. And if you are OSGi developer who now wanders “why should I care?”, let me remind you Thomas Edison’s famous quote “The value of an idea lies in the using of it”! Growing large community around given technology has proven to be an essential part of its success. In this talk I’d like to go over what OSGi community is (not) doing to attract “outsiders”. I’d also argue it can do much better than that. Based on observations and conversation from the last 2 years trying to advocate for OSGi among Java developers. I’ll try to position the technology it today’s reality of microservices, containers, clouds, DevOps, automation, Java 9, … and bring to your attention the perspective of an “outsider” together with all the presumptions, fallacies and promises it comes with. Finally I’d like to share some ideas about how to address those, promote relevant parts of OSGi and thus perhaps make it more attractive to Java developers!

In the ”Internet of Things” (IoT) vision the physical world blends with virtual one, while machine-to-machine interaction improve our daily life. Clearly, how these virtual objects are exposed to us is critical, so that their user interface must be designed to support the easiness of usage that is driven by the users’ needs, which is different from what machines requires. These two requirements must be solved, and an integrated solution should emerge, if we want to bring the IoT to the 50 billions network that is predicted to became in the next years.

Apache Sling as an OSGi-powered REST middleware

Robert Munteanu

Apache Sling is an innovative web framework built on top of the Java Content Repository (JCR), that uses OSGi for its component model and fosters RESTful application design. This presentation will showcase how the Apache Sling framework can be used to build a unified REST-based middleware for multiple data sources, such as MongoDB, Apache Cassandra, Apache Jackrabbit Oak or classical relational databases. In doing so it will present the benefits that come from a single Resource API over multiple data stores, both at the library level and at the HTTP boundary.

The Java Microservice Library

Rick Hightower

The Java microservice lib. QBit is a reactive programming lib for building microservices - JSON, HTTP, WebSocket, and REST. QBit uses reactive programming to build elastic REST, and WebSockets based cloud friendly, web services. SOA evolved for mobile and cloud. QBit is a Java first programming model. It uses common Java idioms to do reactive programming. It focuses on Java 8. It is one of the few of a crowded field of reactive programming libs/frameworks that focuses on Java 8. It is not a lib written in XYZ that has a few Java examples to mark a check off list. It is written in Java and focuses on Java reactive programming using active objects architecture which is a focus on OOP reactive programming with lambdas and is not a pure functional play. It is a Java 8 play on reactive programming. Services can be stateful, which fits the micro service architecture well. Services will typically own or lease the data instead of using a cache. CPU Sharded services, each service does a portion of the workload in its own thread to maximize core utilization. The idea here is you have a large mass of data that you need to do calculations on. You can keep the data in memory (fault it in or just keep in the largest part of the histogram in memory not the long tail). You shard on an argument to the service methods. (This was how I wrote some personalization engine in the recent past). Worker Pool service, these are for IO where you have to talk to an IO service that is not async (database usually or legacy integration) or even if you just have to do a lot of IO. These services are semi-stateless. They may manage conversational state of many requests but it is transient. ServiceQueue wraps a Java object and forces methods calls, responses and events to go through high-speed, batching queues. ServiceBundle uses a collection of ServiceQueues. ServiceServer uses a ServiceBundle and exposes it to REST/JSON and WebSocket/JSON. Events are integrated into the system. You can register for an event using an annotation @EventChannel, or you can implement the event channel interface. Event Bus can be replicated. Event busses can be clustered (optional library). There is not one event bus. You can create as many as you like. Currently the event bus works over WebSocket/JSON. You could receive events from non-Java applications.

API-led Architecture

Techolution

Today, companies have multiple applications parallelly running to support their business operations. Such applications generate petabytes data that is stored in dispersed locations. Consequently, accessing and controlling such applications turns into a challenge, especially when companies are hosting a monolithic IT architecture. This is where API-led architecture makes it easier for companies to consolidate, access, manage and secure data from a unified location through APIs. API-led architectures have proven to enable organizations to deliver cross-application functions.

Secure by Default Web Applications

Robert Munteanu

A product that works is not done, as there are many facets to consider - availability, scalability, security. Of those, security is probably the most costly to get wrong. This talk will build a threat model for a sample web application, showcasing a structured approach to securing your web application. Various vulnerabilities are shown and mitigated, based on current best practices. We take special care to show to eliminate entire classes of vulnerabilities, rather than tackling problems one by one. The code samples will be built on top of Apache Sling, but previous knowledge of Sling is not required. Talk delivered at BaselOne 2023

Sling Applications - A DevOps perspective

Robert Munteanu

Sling is an established web application framework, with a multitude of core features and extensions. It has a very productive inner loop, with OSGi bundle deployment, JCR content editing and live configuration updates. The less-told story is how an application should be assembled, configured, deployed, and monitored. In this talk we will present the main approaches for bootstrapping, deploying, updating, and monitoring Sling-based applications, based on Open Source tools and libraries. The participants will gain a better understanding of the options available for managing their own Sling-based application and will be able to minimise the effort needed to manage such an application.

Will it blend? Java agents and OSGi

Robert Munteanu

Java agents are a little-known but extremely powerful part of the Java ecosystem. Agents are able to transform existing classes at runtime, allowing scenarios such as logging and monitoring, hot reload or gathering code coverage. However, their usage presents a number of pitfalls as well. In this talk we will present the steps of writing a java agent from scratch, indicate various common mistakes and pain points and draw conclusions on best practices. Special care will be taken to discuss how running in an OSGi environment affects Java agents and how we can best approach integration testing in a modular environment. After this talk participants will have a better understanding of the Java instrumentation API, how it fits in with OSGi runtimes and about should / should not be done with it.

Many of the large-scale architectural changes, such as container-based deployments, separation of code and content, horizontal and vertical scaling, etc, are made possible by a host of reimplementations of APIs exposed by the open-source projects that serve as the foundation of AEM. In this talk we will explore a number of such extensions and their implications, such as Oak's principal-based authorization, getting up and running with the composite node store, or indexing in a separation of content and apps scenario. After this talk participants will have a better understanding of various under-the-hood changes present in AEM as a Cloud Service and their practical implications for AEM development. They will also be able to set up their own tweaked Sling instance so they can experiment with such a setup.

Crash course in Kubernetes monitoring

Robert Munteanu

Microservices were born out of a need to enable modularity at a technical and business level. With their mass adoption tehnical patterns and solution have started to emerge, and management using Kubernetes is one of the most encountered. Monitoring application state becomes tedious when using approaches designed for individual servers and deployments. Prometheus and Grafana are cloud-native solutions that make monitoring of Kubernetes deployments a simple and very fruitful task. After this talk participants will understand how to instrument their applications, gather metrics and act on high-level aggregate information.

Java agents for fun and (not so much) profit

Robert Munteanu

Java agents are a little-known but extremely powerful part of the Java ecosystem. Agents are able to transform existing classes at runtime, allowing scenarios such as logging and monitoring, hot reload or gathering code coverage. However, their usage presents a number of pitfalls as well. In this talk we will present the steps of writing a java agent from scratch, indicate various common mistakes and pain points and draw conclusions on best practices. After this talk participants will have a better understanding of the Java instrumentation API and about should / should not be done with it.

Will it blend? Java agents and OSGi

Cloud-native legacy applications

Robert Munteanu

Kubernetes is quickly becoming the de facto deployment platform for container runtimes. New applications can be written with containers in mind, but existing applications are not always aligned to the new best practices. In this talk we will present how an existing application can be deployed on a Kubernetes platform, exploring various patterns such as scaling out, centralised logging and monitoring, content distribution and persistence. After this talk participants will gain a better understanding about how existing applications can be molded into a cloud-native ones with reasonable effort.

Cloud-Native Sling

Robert Munteanu

Kubernetes is quickly becoming the de facto deployment platform for container runtimes. Sling provides a quick out-of-the box experience using the Starter jar, but this kind of setup is not always easy to deploy in containers. In this talk we will present how a Sling application can be deployed on a Kubernetes platform, exploring various patterns such as scaling out, centralised logging and monitoring, content distribution and persistence. After this talk participants will gain a better understanding about how Sling can be molded into a cloud-native applications without sacrificing the features that make Sling a strong development platform.

From Monolith to Modules - breaking apart a one size fits all product into mo...

Robert Munteanu

Adobe Experience Manager as the biggest enterprise application built on the Apache Sling stack over the years was built with a monolithic product perspective. Taming the growth over time and tackling upcoming challenges led to a situation were a transition towards a modular product, where large features can be gracefully removed at runtime, becomes unavoidable. With this talk we want to provide insights on how Adobe uses the available technologies in the stack, extends the stack and transforms the own practices to cut the product in loosely coupled modules with minimal impact on existing consumers. We will be identifying patterns on OSGi, content and scripting side to eliminate and prevent hard wiring and highlight pending challenges and our thoughts on how to resolve that. Last but not least we will share our experience on how such a transition impacts our engineering flow and quality assurance practices.

What's new in the Sling developer tooling?

Robert Munteanu

The Sling developer tooling consists of many projects: Eclipse plug-ins, Maven archetypes and Maven plug-ins are the most widely known. This talk will showcase the results of an initiative to make the Sling IDE tooling less reliant on Eclipse and more usable in other environments. After this talk participants will have a better overview of the various developer tools available for Apache Sling and will be able to choose the tools that make them more productive, irrespective of the IDE they use.

Scaling up development of a modular code base

Robert Munteanu

Microservices are quickly becoming one of the preferred deployment models in the software industry. Much has been said about the runtime impact of microservices, but less about how they impact the development process. This talk will discuss the details of moving from a single monolithic codebase to multiple repositories in terms of the development process. We will present the impact of modularisation on source control, continuous integration, code reviews, IDEs and public discussion on chat/email. After this talk attendees will have a better understanding on the impact of the development process of modular development.

Zero downtime deployments for Sling application using Docker

Robert Munteanu

In this session we'll show how the Composite Node Store, a new Oak feature, can be used together with Docker to perform blue-green deployments. This kind of setup allows to dynamically change a part of the repository (containing the application code), while leaving the content part untouched. The presentation and the demo will be based on the AEM, but the concepts and tools are generally applicable to all Sling-based applications. The building blocks we'll present can be used to develop other mechanisms for zero-downtime deployments.

Building domain-specific testing tools : lessons learned from the Apache Slin...

Robert Munteanu

The Apache Sling project has built a number of testing tools which aid in testing applications that are built on top of this framework - REST-based, assembled using OSGi and backed by JCR. We will review how those testing tools fit in with domain-agnostic testing tools such as JUnit and Mockito and what the benefits and pitfalls are when building your own domain-specific tools. Similar techniques apply to projects not using the same technology stack, so the discussion will bring value to all projects which can benefit from domain-specific testing tools.

So how do I test my Sling application?

Robert Munteanu

Developing a Sling application is only half the story - or perhaps even less. Automated testing is of great importance for insuring code quality and reducing regression risk. Sling presents an interesting challenge, as its technology stack does not get as much attention as more mainstream ones. As such, we had the pleasure of developing our own patterns and testing tools, while integrating the foundations that already existed. This presentation will walk through the various available tools and show how they can be used to cover a Sling-based application.

Jen Stirrup

The Metaverse is popularized in science fiction, and now it is becoming closer to being a part of our daily lives through the use of social media and shopping companies. How can businesses survive in a world where Artificial Intelligence is becoming the present as well as the future of technology, and how does the Metaverse fit into business strategy when futurist ideas are developing into reality at accelerated rates? How do we do this when our data isn't up to scratch? How can we move towards success with our data so we are set up for the Metaverse when it arrives? How can you help your company evolve, adapt, and succeed using Artificial Intelligence and the Metaverse to stay ahead of the competition? What are the potential issues, complications, and benefits that these technologies could bring to us and our organizations? In this session, Jen Stirrup will explain how to start thinking about these technologies as an organisation.

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process. In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

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.
