First of all congratulations on the book itself and thanks for the opportunity provided to us for winning it.
Having worked always on Enterprise Solutions and having infrastructure taken care for me within walls of the company I work in (so obviously not experienced with the cloud), my question is:
Could you please provide:
a) What are the alternatives/competition to OpenShift
b) What advantages/disadvantages (if any) does OpenShift bring to the table?
Question on the book itself:
a) What was the motivation to write this book?
You are very welcome, good luck with winning a copy, it is worth it for you to get started on OpenShift.
I come from the same background, working for enterprises and used to having to request resources for my projects. This way of working that I cover in my book is a revelation. Trust me, it changes the game. Privately you can work with OpenShift anywhere that you have a connection. Within your work you will start seeing changes over the coming years that companies are starting to enable their resources as a pool, not as individual machines. This is what Red Hat refers to as 'hybrid open cloud', using existing resources in an enterprise along with public external resources for scaling out if needed.
The OpenShift concept is a way of working that abstracts a lot of the resource problems out of the developers control. Perfect, now you can concentrate on your development! Give it a spin, you will not regret it.
Ok, the questions:
1. alternatives abound, as listed by Mohamad.
2. advantages are the single way of working, focusing on your development and no longer having to mess around with the development stack. Disadvantages, for some, that you no longer get to mess with the stack, that you will have to produce more development progress in your projects and that you are doing what you were hired to do!
3. my motivation to write this book were based on how I work within the IT. I believe you need to teach. In my job I have the chance to speak and write a lot on the various topics around OpenShift and JBoss Integration products. I was so fascinated by OpenShift, how easy, straight forward, and effective it was. I had to dig in deeper, I started blogging about it, speaking about it, and that sort of rolled into the OpenShift Primer after about eight months. It was a very easy book to write!
Hope you win a copy, but if not, it is not very expensive. ;)
