With virtually every vendor/provider on the planet jumping on the Cloud
Computing bandwagon, sometimes it's difficult to tell whether a service is
truly a Cloud Computing offering or simply a pre-existing offering that has
the Cloud label slapped on it, such as hosting, outsourcing, ASP (Application
Service Provider), On Demand Computing, Grid computing, Utility computing,
SaaS (Software as a Service) and so on.
In fact, Cloud Computing is not a technology revolution, but rather a process
and business evolution on how we use those technologies that enables Cloud
Computing as it exists today: SaaS, inexpensive storage, REST, AJAX,
SOA(service-oriented architectures), On Demand Computing, Grid Computing,
Utility Computing, virtualization, etc.
The issue is that many providers of those technologies hijacked the term
Cloud Computing, and it is this confusion that discredi... (more)
In the previous article we looked at some Cloud Security Advantages.
Now let's now look at some Cloud Challenges.
• Trusting vendor’s security model
• Customer inability to respond to audit findings
• Obtaining support for investigations
• Indirect administrator accountability
• Proprietary implementations can’t be examined
• Loss of physical control; Data dispersal and international privacy laws
• Need for isolation management
• Logging challenges
• Data ownership issues
• Quality of service guarantees
• Dependence on secure hypervisors
• Attraction to hackers... (more)
In the previous article Cloud Equals SaaS, Grid, Utility Computing,
Hosting...? I made the following statement:
"SaaS is one of the three possible Cloud Computing delivery modes; however,
to be considered Cloud Computing, any of those delivery modes must have
certain specific characteristics"
So, in this article we will look at those specific characteristics that
define exactly what is Cloud Computing, so that next time you will be able to
evaluate if a specific offer is truly Cloud Computing, or simply a
pre-existing offering that has the Cloud label slapped on it.
We can state t... (more)
Business managers know that in spite of the benefits of every new
technology/business model, there are also risks and issues like trust, loss
of privacy, regulatory violation, data replication, coherency and erosion of
integrity, application sprawl, and dependencies, among others.
Therefore they realize that rushing things when it comes to Cloud Computing
can be a very bad decision. However, ignoring Cloud Computing all together,
because of a belief in your ability to secure your own environment better
than a service provider ever could, or jumping rapidly into it because the
Cloud Computing gives you access to completely different levels of scale and
economics in terms of the ability to scale very rapidly and to operate IT
systems more cost-effectively than previously possible, as we can see by the
results of the following poll:
We can say that the three main categories of benefits are:
1. delivery of service (faster time-to-value and time-to-market)
2. reduction of cost (CapEx vs. OpEx tradeoff and costs that are more
3. IT department transformation (focus on innovation vs. maintenance &
