Survival of the Agile

Survival of the agile

By Ruben van der Zwan

Agile is not one ‘thing’ but a number of approaches or methodologies to develop faster. Think about Scrum, Kanban and other frameworks. The Wikipedia definition describes the broader view. But agility is about one word in the dictionary definition: Adaptable! For me, agility is being able to change course as quickly as possible. Your IT should be like a speedboat, not an oil tanker. Mind you, I am talking more about the manoeuvrability in this case than about speed.

Faster time to market with WSO2 Cloud and WSO2 API Manager

Faster Time to Market with Cloud and APIs

By Ruben van der Zwan

Proverbs embody common wisdom. There is a saying much haste less speed. The meaning of this is of course that if you go too quickly the speed with which you are progressing is lower. This is a saying that we also have in the Netherlands as well as in Germany and even the ancient Greeks had similar saying: “Festina Lente”. The way that we look at the time to market is however changing!

Social media - WSO2 API Manager

Creating a WSO2 API Manager Store without Forum and Social Media possibilities

By Rob Blaauboer

Recently, a colleague came to me about disabling and removing comments in the Store of a WSO2 API Manager deployment. This is of course possible. By this I mean without really messing with the source code of the product itself. In this blog, I will show you where the comments are stored and how you can disable the features for social interaction in the WSO2 API Manager.

What is an API?

What is an API?

By Ruben van der Zwan

I sometimes get the question what is an API? I like that question for two reasons: first of all, there is no such thing as a stupid question. If you don’t know something, you ask it. The second reason is that when we talk about APIs, it is good to understand how everyone sees and understands it.

Getting started

Getting started with WSO2 Enterprise Integrator

By Rob Blaauboer

I’ve been a WSO2 trainer at Yenlo for the past 4 ½ years. If there is one thing that I’ve learned is that the products from WSO2 are not very complex in the sense that you need to be a rocket scientist to work with it. However, they do offer a lot of options that can be overwhelming to a novice user so training and practice are needed. In this blog, I would like to give you some guidance on how to get started with WSO2 Enterprise Integrator.
