If you have been thinking how to choose your public cloud vendor you are not
the only one. There are hundreds of offerings that you can choose from and
comparing those can be a cumbersome exercise. Hence most of the people just
run to the vendor (or technology) they are either most familiar with or gives
them the best price. This is all good until they discover that… well, that
vendor is not what they have been looking for.
Lately I've been few times asked: "Which public cloud provider would you
recommend to deploy our application?" Doesn't matter how much I want it to
be, the answer is unfortunately not that simple. Here are few questions to
ask yourself while doing the research.
Do you plan to migrate existing applications or to develop brand new
Very few if any legacy applications are designed with cloud patterns in mind.
Things like sticky sessions... (more)
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.
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

Few days ago I noticed a question on a LinkedIn group that made me thinking
how important is the notion of private clouds. First, let's briefly look
at what is the difference between public, private and community clouds as
well as hybrid clouds. Once again those are very well defined in NIST

Private Cloud is cloud infrastructure that belong to single organization
(enterprise, university, government organization etc.) that is hosted either
on or off premise and is managed by the organization or third party
With cloud computing becoming the center of almost every new enterprise IT
project, more and more startups decide to compete in the area. This raises
the question: "Are they ready to fulfill the enterprise needs?" Forget the
need to have one big customer. This can open few doors but if your startup's
business strategy is wrong those will be shut down soon. It is true that one

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?"
Let's first elaborate on a two misconceptions about Open Source.
Open Source Is Free
Not really! 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)
