Lately we have seen a lot of articles discussing how easy Disaster Recovery
in the cloud is but very few of those put the emphasis on talking about the
basics of Disaster Recovery and educating customers on why they should be
thinking about it. Mostly such articles concentrate on the technologies
that can be uses and how to do Disaster Recovery.
I would like to start with the basics and write about few Myths About
First, let's relate Disaster Recovery to something that is more close to us
in real life. The first thing that comes to mind as an analogy is the
insurance policies that we pay for our health or our home or our car.
Disaster Recovery is almost the same - we invest money in something that we
do not need immediately but that pays off when a disaster occurs. Well, I
write almost because there is a slight difference. Let's take for example ... (more)
Experiencing downtime is not something that companies wish for but as we
have seen lately it is something that we hear quite often about.
Interestingly enough very few enterprises, especially in the Small and

As described in the last week's post NIST defines three different cloud
computing service models - IaaS, PaaS and SaaS. IaaS and SaaS are really easy
to grasp but I see people struggling to understand the PaaS model. As a
long-time application developer though I find the PaaS model the most
compelling one for new applications. Here is why.
I will look at two examples: one enterprise and one from the consumer world.
Let's start with the enterprise scenario. If you examine any enterprise
application portfolio you will find out that almost every development team
has implemented it'... (more)
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

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
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... (more)
