While reading the news yesterday I stumbled upon the following article in Puget Sound Business Journal - Why is Microsoft alienating its biggest customers? IT pros want TechNet back. Everybody has the right to complain and sign a petition but more important is to understand the message Microsoft sends. Some think of it as "Microsoft doesn't care about IT Pros anymore", and they may be right; but the message sounds to me more like "Hey, IT Pros - the world is changing!" Although I think Microsoft could be a little bit more responsive to the complaints, I don't think IT Pros should be so worried. Here is why. The Problem With The Downloads While $349 annually for the whole collection of Microsoft software is a very attractive price I think free software is a better option. Although slow, Microsoft showed its commitment to change in the last few years. Although I don... (more)

Open Source in the Cloud - How Much Should You Care?

In his opening keynote for Red Hat Summit, Jim Whitehurst, the CEO of Red Hat asked the audience: "Name an innovation that isn't happening in Open Source - other than Azure!" I can certainly add iPhone and AWS to the mix but let me stick to the cloud topic with the following question: "How much Open Source matters in the cloud?"

In the cloud doesn't matter whether you are running on an Open Source platform or not - it is NOT free because you pay for the service. And for long Open Sou... (more)

Essential Cloud Computing Characteristics

If you ask five different experts you will get maybe five different opinions what cloud computing is. And all five may be correct. The best definition of cloud computing that I have ever found is the National Institute of Standards and Technology Definition of Cloud Computing. According to NIST the cloud model is composed of five essential characteristics, three service models, and four deployment models. In this post I will look at the essential characteristics only, and compare to the traditional computing models; in future posts I will look at the service and deployment models... (more)

Cloud Computing Service Models

In this post I will look at the three different service models for cloud computing as defined by NIST. More specifically I will look at the management and operations overhead for each one of the models and compare it to the traditional on-premise model. Traditional Model Let's look at how things have been done in the past. Traditionally enterprises have been responsible for managing their own IT infrastructure as well as the software stack that runs their applications. For small companies that meant hiring polyglot employees with wide range of skills varying from low level netw... (more)

Is Your Cloud Ready for the Enterprise?

Reading my newsfeed this morning I noticed several articles talking about the cloud and the enterprise. There is no doubt that the area is heating up with more and more acquisitions (IBM buys Softlayer), investments (GE invests $105M in Pivotal) and fights over big deals (IBM vs. AWS for the CIA cloud) but the question that comes up is: "Are the cloud platforms ready for the enterprise?" Being involved with numerous cloud projects I see five areas that enterprises emphasize when they evaluate their options. Those are not too different from the criteria they use for any other sof...
