Oh Dear, the Green Pundits Don’t Understand the Cloud or Multitenancy
Recently I was drawn into a discussion of how Green the Cloud is where I responded as follows: SaaS is going to come out ahead of any reasonably calculation of carbon emissions versus on-prem. Multi-tenancy is just a lot more efficient. Look at the data centers of companies like Google, Amazon, and Facebook. Most corporates wish they […]

Dreamforce Wrap-up
Dreamforce Wrap-up Ok, we survived Dreamforce and that has enabled us to limp home exhausted from all of the information we accumulated and the parties we attended just in time for the holidays. I have a lot of thoughts about the show and if I try to share most of them the result will be […]

Multi-tenancy: are they selling you a pup?
Vendors argue that multi-tenancy does or doesn’t matter in direct proportion to the extent to which it figures in their application architecture. What’s their real agenda?

Multi-Tenancy Debate Won’t Go Away
Under more normal conditions I react to blogs on a low key basis. If I like something I might not even mention it and the same is true if I dislike or disagree with one. The blogosphere is a big place and it is unproductive to be running around all day saying “Yes, I like […]

Making Sense of "Multi-tenancy" Claims
Single-tenant, Multi-tenant, Mixed-tenant, Mega-tenant, Tenant-tenant, Loo-tenant, ….. It’s ridiculous what lengths software vendors go to when they really want to confuse buyers.

The Unbearable Lightness of Multitenancy in the Cloud
If y’all are not in the mood to listen to a (well reasoned, researched, educated and well-timed) rant, move along. This is me ranting about vendors trying to confuse users when it comes to cloud topics. If you are interested in why multitenancy should not be an item of discussion, then read on. Consider y’all […]

Is It Really SaaS If?
If It Looks Like A Duck… I’ve long since put to rest the whole multi-tenancy debate around SaaS. If it isn’t multi-tenant, then it isn’t SaaS. You can host/subscribe single tenant software, and with piles of virtualization and other techniques for optimizing data center/operations costs, you may be able to approximate the operations costs […]

SaaS will dominate your cloud strategy
The chart in Larry Dignan’s blog post end of last week reporting Forrester’s projection for a $241 billion cloud computing market by 2020 clearly shows the relative market shares for SaaS, PaaS and IaaS. It’s a graphic reminder that, if an enterprise is focusing on the infrastructure layer to build its cloud strategy, then it’s […]

Multi-tenancy and the Mainframe
People often say that cloud computing is just a reinvention of the service bureaus of old. Rather than being a forward advance, they suggest that accessing all our applications and data from vast, centralized cloud platforms is a lurch backwards to the time-honored mainframe model of computing. But perhaps instead cloud computing will force a […]

Further Illumination
I don’t like ambiguity and there was some in yesterday’s post so let’s get to it. Yesterday I wrote: Microsoft is confidently offering replacement systems that have been the beneficiaries of significant investment over the last several years. These systems also run on cloud infrastructure, though cloud does not necessarily mean multitenant. Microsoft and others […]
