The Macro and Micro of Multi-tenancy Regarding Private Cloud

I was recently reviewing some sales and marketing materials regarding building out Infrastructure-as-a-Service (IaaS). Part of these materials included attributes of IaaS, one of which is multi-tenancy. Having been working with some large enterprise customers lately around private cloud, this attribute really got me thinking. In most cases for the enterprises I have been working… Read More »

Cloud Should Be Defined By What It Will Become, Not What It Is Today

There’s been a lot of discussion about what makes cloud computing different than other forms of computing that have come before. Some refer to the set of attributes set forth by NIST, while others rely on less succinct qualifications simply satisfied to identify network accessible services as cloud, and others define cloud by applicable business… Read More »

The Key to Private Cloud Is Removing IT Stratification

One of the leading problems plaguing IT organizations is the high costs of operations and maintenance.  The industry average is roughly 70% with some organizations going as high as 90%. Picking apart these costs one often finds a stratified organization focused on narrow bands of computing with little crossover between the bands. Moreover, the weighting… Read More »

Thar Be Danger in That PaaS

There’s a lot of momentum behind moving to Platform-as-a-Service (PaaS) for delivery of applications on the cloud, but is there enough maturity in PaaS to deploy a mission-critical application? Here’s a story regarding one loyalty program provider that offers his customers SaaS solutions. This SaaS provider deployed his platform on a PaaS that offered SQL… Read More »

Cloud Multi-tenancy Includes Network Bandwidth

There’s been a lot of discussion about multi-tenancy since the arrival of cloud computing. Multi-tenancy is the act of hosting multiple non-related resource allocations on the same hardware. For example, with regard to virtual machine instances, the concepts surrounding multi-tenancy are multiple virtual machine instances all running on the same servers sharing the CPUs, memory,… Read More »

SaaS, Paas, IaaS: Which of These Things is not Like the Others?

There’s an interesting debate raging over at Focus.com (a newly formed site that is dedicated toward facilitating the sharing and exchange of information as well as provide access to subject matter experts). The question was posed, “Is Facebook a cloud?” Clearly, there’s differing opinions on the response to this question, which makes for good reading… Read More »

In Consideration Of Transitioning Email to the Cloud

So it seems that with regard to Kundra’s 25-point plan and the mandate to move three applications to the cloud in 18 months that email seems to be the primary target for the first transition.  The decision to move email into the cloud is a relative no-brainer.  Email needs to be ubiquitous, accessed across a… Read More »

Scale is the Common Abstraction of Cloud Computing

In my experience, for there to be widespread adoption and agreement over a concept, the semantics surrounding that concept must be unique and discrete. If the definition is too broad, there will be too much opportunity for dissenting opinion. NIST’s definition of cloud computing doesn’t really answer the mail when it comes to delivering a… Read More »

The Game is Always Changing: A Non-technical Perspective on Cloud Computing

It’s not about what’s different, it’s about getting on board with the changes in the game or get left behind. People say, “What’s so different about Cloud Computing?”, “This is nothing more than managed hosting or mainframe computing redux”, “what’s old is new again”.  What was it that Gordon Gekko says to Jake on the… Read More »

Living La Vida Cloud!

If you’ve been watching broadcast television anytime over the past few months you’ve most likely come across the Microsoft “To the Cloud” commercial.  Microsoft does their best to bring complex technologies to the mainstream, but sometimes … For most people, the Cloud is something they will never directly touch, but instead will be exposed to… Read More »
