Blog postAs a consulting architect at Red Hat, I've had the privilege of working on legions of customer projects. Every customer brings their own challenges but I've found some commonalities. One thing most customers want to know is how to coordinate writes to more than one system of record. Answering this question typically involves a long explanation of dual writes, distributed transactions, modern alternatives, and the possible failure scenarios and drawbacks of each approach. Typically, this is th

Blog postThere is a fantastic talk by Martin Kleppmann called “Turning the database inside-out”. Once watched, it can change your perspective on databases and event logs irreversibly. While I agree with the outlined limitations of databases and the benefits of event logs, I’m not convinced of the practicality of replacing databases with event logs. I believe the same design principles used for turning databases inside-out, should instead be applied at a higher, service design level to ensure microserv

Blog postApache Kafka is designed for performance and large volumes of data. Kafka's append-only log format, sequential I/O access, and zero copying all support high throughput with low latency. Its partition-based data distribution lets it scale horizontally to hundreds of thousands of partitions.
Because of these capabilities, it can be tempting to use a single monolithic Kafka cluster for all of your eventing needs. Using one cluster reduces your operational overhead and development complex -
Blog post“We build our computers the way we build our cities—over time, without a plan, on top of ruins.”
Ellen Ullman wrote this in 1998, but it applies just as much today to the way we build modern applications; that is, over time, with short-term plans, on top of legacy software. In this article, I will introduce a few patterns and tools that I believe work well for thoughtfully modernizing legacy applications and building modern event-driven systems.
Note: If you prefer watch my ta -
Blog postThese days, there is a lot of excitement around 12-factor apps, microservices, and service mesh, but not so much around cloud-native data. The number of conference talks, blog posts, best practices, and purpose-built tools around cloud-native data access is relatively low. One of the main reasons for this is because most data access technologies are architectured and created in a stack that favors static environments rather than the dynamic nature of cloud environments and Kubernetes.

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.
Open Source Eras and relative adoption trend lines
In this post, I will look at open source evolution broadly, try to analyze what are some of the triggers and enablers for the chang -
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 source

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. 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. The list contains books that are sponsored and offered free of charge but in most cases that is for exchange of your contact details. If you prefer no

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.
Lack of attention
Today, we live in a different world. There is an endless amount of resources for learning, from blo -
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. Let’s see a few of t

Blog postThis is a guest post by freelance editor and copywriter Laila Mahran.
When using Application Performance Monitoring, you’re able to monitor key app performance metrics about the performance of a web application in production. APM is often thought of as a ‘second wave’ of performance monitoring techniques, which was preceded by traditional host-based monitoring. Let’s dive in more. Host-based monitoring focuses on indicators such as:StorageMemoryCPUNetwork utilizationApplication mon -
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.
Recently I’ve blogged about “Multi-Runtime Microservices Architecture” where I ha -
Blog postAs an architect in the Red Hat Consulting team, I’ve helped countless customers with their integration challenges over the last six years. Recently, I had a few consulting gigs around Red Hat AMQ 7 Broker (the enterprise version of Apache ActiveMQ Artemis), where the requirements and outcomes were similar. That similarity made me think that the whole requirement identification process and can be more structured and repeatable. This guide is intended for sharing what I learned from these few

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 postHere are the must-know top 10 design patterns for beginners synthesized from the Kubernetes Patterns book. Getting familiar with these patterns will help you understand foundational Kubernetes concepts, which in turn will help you in discussions and when designing Kubernetes-based applications. There are many important concepts in Kubernetes, but these are the most important ones to start with:
Top 10 most common Kubernetes Patterns

Check out my new Kubernetes Patterns book and follow me @bibryam for future blog posts.A look at the past decadeThe integration space is in constant change. There are many open source projects and closed source technologies that have not passed the test of time and disappeared from the middleware stacks for good. After a decade, Apache Camel is still here and becoming even stronger for the next decade of integration.

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 mult -

Open source is like a forestA forest is a complex ecosystem of plants, animals microorganisms, non-living material, all balanced delicately by nature. It requires the right geography, the right soil, the right amount of rain and sun, and decades to build a forest.
So is open source. An open source project is a delicate ecosystem of contributors, reviewer, users, supporting organiza -

Recently I had a chance to play a little bit with the open source permissioned JVM based blockchain platform Corda. I was surprised to discover how it blends blockchain ideas with the commodity middleware technology and creates a new brief of decentralized enterprise integration. Below are my first impressions from it along with an Apache Camel connector contribution.

Blog postI've been involved with open source over a decade now. I've been part of small projects with innovative ideas which grew into large projects with solid communities. I've also witnessed how dysfunctional communities can suck the energy of projects for years. All that thanks to the open source development and collaboration.
In recent times, I'm active on the blockchain space as well: reading, writing, and contributing to projects. And I came to the conclusion that blockchain projects are sta -
Blog postToday’s developers aren’t just kingmakers; thanks to blockchain, they’re building their own kingdoms.
The New Kingmakers"The New Kingmakers" by Stephen O'Grady is a great book explaining why the developers are the most important assets a business has. In it, Stephen explains how developers are shaping products in new ways and organizations that understand and embrace the value of this shift will be the most successful in the years to come. It shows how IT decision makers ar -
