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 that Cloud Computing allows business to increase IT capacity (or add capabilities) on the fly and in real time (Internet-enabled), without investing in new infrastructure, training new personnel or licensing new software, and as a pay-per-use service. However, the above definition is not comple... (more)

Rushing To Cloud Computing Can Be Bad

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 man...

Why Public & Private Sector Organizations Are Considering Cloud Computing

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 competitive) 3. IT department transformation (focus on innovation vs. maintenance & implementation) During economic downturns, the abilit... (more)
