How the TOGAF Standard Serves Enterprise Architecture
Any architect working with large enterprise systems has probably looked for guidance on how to manage the complexity and communicate with various stakeholders. This introductory overview of the TOGAF standard explains the structure of the framework, as well as discusses the benefits of using enterprise architecture to manage complex systems.

Democratizing Stream Processing with Apache Kafka® and KSQL - Part 2
In this article, author Robin Moffatt shows how to use Apache Kafka and KSQL to build data integration and processing applications with the help of an e-commerce sample application. Three use cases discussed: customer operations, operational dashboard, and ad-hoc analytics.

Refactoring to a Deeper Model
Paul Rayner uses a case study to demonstrate how refactoring your code can lead to a deeper understanding of your domain model. Through common code refactorings, combined with the implementation of patterns, the codebase became more cohesive and easier to reason about, reducing the time to perform some common tasks from weeks or months to just hours.

Microservices in a Post-Kubernetes Era
How are microservices standing in the Kubernetes era? The microservice architecture is still the most popular architectural style for distributed systems. But Kubernetes and the cloud-native movement have redefined certain aspects of application design and development at scale.

A Critique of Resizable Hash Tables: Riak Core & Random Slicing
This fall, Wallaroo Labs will be releasing a large new feature set to our distributed data stream processing framework, Wallaroo. One of the new features requires a size-adjustable, distributed data structure to support growing & shrinking of compute clusters. It might be a good idea to use a distributed hash table to support the new feature, but what distributed hash algorithm should we choose?

Build a MySQL Spring Boot App Running on WildFly on an Azure VM
How to build a demo site that runs on the WildFly application platform and connects to a MySQL database in the cloud, on Microsoft Azure. The premise seems simple, but the implementation can be tricky, and there is limited documentation on how to set something like this up.

The Argument for WCF Hosting in .NET Core
Should WCF Hosting be Supported in .NET Core? To a lot of people this seems like a strange question; the answer is obviously... yes? no? Well actually it is quite contentious with people on both sides of the issue fiercely arguing for their position. We’ll try to unpack the debate and explain the arguments on both sides.

How to Choose a Stream Processor for Your App
Choosing a stream processor for your app can be challenging with many options to choose from. The best choice depends on individual use cases. In this article, the authors discuss a stream processor reference architecture, key features required by most streaming applications and optional features that can be selected based on specific use cases.

Microservices from a Startup Perspective
When starting a journey to microservices, knowing what to consider might be overwhelming. No golden rule that is easily applicable exists. Every journey is different, since every organization is facing different circumstances. In this article I am sharing some lessons learned and challenges from a startup perspective, and what I would do differently the next time introducing microservices.

Increasing Security with a Service Mesh: Christian Posta Explores the Capabilities of Istio
Istio attempts to solve some particularly difficult challenges when running applications in a cloud platform: application networking, reliability, and observability and (the focus of this article) security. With Istio, communication between services in the mesh is secure and encrypted by default. Istio can also help with "origin" or "end-user" JWT identity token verification.

Envoy Service Mesh Case Study: Mitigating Cascading Failure at Lyft
Over the past four years, Lyft has transitioned from a monolithic architecture to hundreds of microservices. As the number of microservices grew, so did the number of outages due to cascading failure or accidental internal denial of service. Today, these failure scenarios are largely a solved problem within the Lyft infrastructure due to the use of the Envoy Proxy as a service mesh.

Evaluating Hyperledger Composer
Hyperledger Composer is a new open source project which makes it easy for developers to write chaincode for Hyperledger Fabric and the decentralized applications (DApps) that can call them. This article summarizes a technical evaluation of the performance characteristics of using Composer in a test application.
