Last week I wrote a guest blog post for Washington Technology Industry
Association explaining What Applications Benefit the Most from the Cloud.
While working on the post I looked around the Web and once again was reminded
that, like with other technology the cloud is becoming more and more
confusing. Don't understand me wrong! I do love the technology but there is
always one thing that always baffles me - we (the techies) always invent new
fancy terms and try to use those to sell the technology (it even happens
quite often that we just call an old technology with new name and sell it
again). Well, we are pretty good at confusing our customers with our fancy
TLAs (TLA stands for three-letter-acronyms if you are wondering :)) hence I
decided to start a series of posts explaining the cloud with much simpler
One of my favorite questions when I interview people... (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
low level netw... (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
for long Open Sou... (more)
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
At the Prepare for Multi-Cloud Future panel yesterday the guys from
Equinix, Redapt, RightScale and Datapipe offered great insights about
the challenges of using multiple clouds. One of those is of course
estimating the cost of running your application in the cloud or in multiple
clouds. With that in mind I wanted to elaborate a bit more on what should you
think about when doing the estimate.
Quite often you will see IT or business teams estimate the cloud costs only
based on the compute power and storage that they need. One quite often
overlooked component of the cloud cost is ... (more)
