Blog postOpen source is the current norm for developer collaboration and customer adoption in software. It is the foundation that enabled unicorns and cloud providers to build their services from the ground up. But that wasn’t always the case with open source, and it is changing and evolving again.

Blog postOpen source is a distributed innovation model that lacks distributed funding. It allows individuals with a common passion to collaborate and produce value but not capture it. It is a production factory, without a sales counter. That is why many open source contributors are not getting a fair return. That is why many companies capture value from open source but without paying back. That is why many independent open source builders use alternative means to fund themselves. That is why open source5 months ago Read more

Blog postThere is a rise in offerings of free educational content, free software, free cloud resources with the single goal of capturing the new kingmaker's attention. While this is a change for good, I predict that is not going to be enough and this trend will only increase in the future. In a similar spirit, here I want to quickly share my favorite Kubernetes related books offered free of charge. I've read and found them all very useful at different stages of my learning.

Blog postLack of freeWhen I was at university, I had to pick between Java and .Net to direct my career. At the time, there were tons of Java books, docs, and even IDEs for free. But only very few .Net books and tools for Microsoft's environments and all of them were expensive for me. Living in a 3rd world country, I made my decision based on available free learning resources.

Blog postThe term asynchronous means “not occurring at the same time” and in the context of distributed systems and messaging it implies that the processing of a request occurs at an arbitrary point in time. There are many advantages of asynchronous interactions over synchronous ones but also new challenges introduced by it. In this post, we will focus on a few specific considerations for choosing a suitable asynchronous messaging infrastructure for implementing event-driven systems.

Blog postToday’s developers are expected to develop resilient and scalable distributed systems. Systems that are easy to patch in the face of security concerns and easy to do low-risk incremental upgrades. Systems that benefit from software reuse and innovation of the open source model. Achieving all of this for different languages, using a variety of application frameworks with embedded libraries is not possible.

Blog postCreating good distributed applications is not an easy task: such systems often follow the 12-factor app and microservices principles. They have to be stateless, scalable, configurable, independently released, containerized, automatable, and sometimes event-driven and serverless. Once created, they should be easy to upgrade and affordable to maintain in the long term. Finding a good balance among these competing requirements with today’s technology is still a difficult endeavor.

Blog postBelow is the conclusion from an article I wrote at TechCrunch. Checkout the full article here.
Enterprise integration has multiple nuances. Integration challenges within an organization, where all systems are controlled by one entity and participants have some degree of trust to each other, are mostly addressed by modern ESBs, BPMs and Microservices architectures. But when it comes to multi-party B2B integration, there are additional challenges. These systems are controlled by mult2 years ago Read more -

Looking back. And forth.The microservices architecture was born as a technological answer for the iterative Agile development methodology. At the early days of microservices, many companies were doing a form of Agile (XP, Scrum, Kanban, or a broken mixture of these) during development, but the existing software architectures didn't allow an incremental way of design and deployment. As a result, features were developed in fortnight iterati3 years ago Read more -

The way developers design, build, and run software has changed significantly with the evolution of microservices and containers. These modern architectures use new primitives that require a different set of practices than most developers, tech leads, and architects are accustomed to. With this focused guide, Bilgin Ibryam and Roland Huß from Red Hat provide common reusable elements, patterns, principles, and practices for designing and implementing cloud-native applications on Kubernetes.
Each pattern includes a description of the problem and a proposed solution with Kubernetes specifics. Many patterns are also backed by concrete code examples. This book is ideal for developers already familiar with basic Kubernetes concepts who want to learn common cloud-native patterns.
You’ll learn about the following pattern categories:
- Foundational patterns cover the core principles and practices for building container-based cloud-native applications.
- Behavioral patterns explore finer-grained concepts for managing various types of container and platform interactions.
- Structural patterns help you organize containers within a pod, the atom of the Kubernetes platform.
- Configuration patterns provide insight into how application configurations can be handled in Kubernetes.
- Advanced patterns cover more advanced topics such as extending the platform with operators.
About This Book

Who This Book Is For
This book is intended for developers who are familiar with Apache Camel syntax but are perhaps lacking the wider application integration experience. There is no code in this book, only practical theory backed up by countless hours of riding Apache Camel.Other Resources

In Detail
With new APIs and technologies emerging every day, the need for integrating applications is greater than ever before. With the right tools, integrating applications is not hard. Apache Camel is the leading open source integration and message orchestration framework. Apache Camel, which has a variety of connectors and features numerous well-known integration patterns, has an enormous advantage over home grown integration solutions.
Instant Apache Camel Message Routing helps you to get started using the Camel routing engine and Enterprise Integration Patterns. This book will show you how to create integration applications using Apache Camel. You will learn how Camel works and how to leverage the Enterprise Integration Patterns for message routing.
Instant Apache Camel Message Routing is a practical and step-by-step guide to Apache Camel and integration patterns. This book will show you how Apache Camel works and how it integrates disparate systems using Enterprise Integration Patterns. The book starts with an advanced level overview of the Camel architecture before diving into message routing principles. Then, it introduces a number of patterns, complete with diagrams, common use cases, and examples about how to use them with Camel. The book also shows you how to test and monitor Camel applications and cope with failure scenarios.
Approach
Filled with practical, step-by-step instructions and clear explanations for the most important and useful tasks. This short, instruction-based guide shows you how to perform application integration using the industry standard Enterprise Integration Patterns.
Who this book is for
This book is intended for Java developers who are new to Apache Camel and message- oriented applications.
