Ballerina Tutorial: A Programming Language for Integration
Ballerina is a new programming language and platform whose objective is to make it easy to create resilient services that integrate and orchestrate across distributed endpoints. Ballerina’s design principles focus on baking integration concepts into a language, including a network-aware type system, sequence diagrammatic syntax, concurrency workers, being “DevOps ready”, and environment awareness.

Ballerina Microservices Programming Language: Introducing the Latest Release and "Ballerina Central"
The tutorial demonstrates Ballerina, a new programming language and platform whose objective is to make it easy to create resilient services that integrate and orchestrate across distributed endpoints. Ballerina uses compile time abstractions for distributed system primitives that enable the compiler to generate artifacts like API gateways for deployment to Docker and Kubernetes.

Events, Flows and Long-Running Services: A Modern Approach to Workflow Automation
Recent discussions around the microservice architectural style has promoted the idea that “to effectively decouple your services you have to create an event-driven-architecture”. Although events can decrease coupling, we must avoid the mistakes of traditional SOA: centralised control should to be avoided, and workflow engines must be less painful to use and operate.

Approximate Queries on WSO2 Stream Processor: Use of Approximation Algorithms in an Applied Setting
In this article, we describe an example real world application of API monitoring which benefits from using approximate stream processing. We developed the application on top of WSO2 Stream Processor as Siddhi extension. Siddhi is the complex event processing library which acts as the event processing engine of WSO2 Stream Processor.

Uwe Friedrichsen on Functional Service Design and Observability
At the microXchg 2017 conference, Uwe Friedrichsen discussed the core concepts of “Resilient Functional Service Design” and how to create observable systems. Friedrichsen believes that microservice developers must: learn about fault tolerant design patterns and caching; understand Domain-Driven Design (DDD) and modularity; and aim to design for replaceability of components rather than reuse.

An "Integration-First" Approach to Building a Commerce Platform for Payment Terminals
In this article Praveen Alavilli describes how they designed a payment terminal system for interoperability and extensibility, allowing developers to build new shopping experiences.

Perspective on Architectural Fitness of Microservices
In this article we peel the onion of potential architectural fitness of microservices in the context of Master Data Management, and the challenges a microservices-based architecture may face when solving problem domains that require compute-intensive tasks, such as the calculation of expected losses on a portfolio of unsecured consumer credit.

Know the Flow! Microservices and Event Choreographies
This article explores ways to implement services which are long running and stretch across the boundary of individual microservices using event based architectures.

Always Be Publishing: Continuous Integration & Collaboration in Code Repositories for REST API Docs
API documentation is an often overlooked part of making any API a success. This article explores how to make the documentation part of a continuous integration pipeline keeping it closer to the code itself.

The Misaligned Middle and Getting off the Hamster Wheel Using Kanban
At the Agile 2016 conference, Dominica DeGrandis and Julia Wester of Leankit gave talks on helping middle managers adapt to change and how Kanban can be used to identify problems in workflows, which people need to address.

An Open API Initiative Update
The Open API Initiative group is evolving what has become the de-facto standard API Description Format to produce a consistent and compatible format for describing APIs, allowing interoperation between tooling, systems, and runtime environments. Tony Tam, creator of the popular Swagger Specification is providing an update on the group activity.
