From Both Sides Now
Looking at Cloud Technology in BAS Applications
John Petze, C.E.M.
It’s probably worth starting with a definition – not mine but NIST’s:
When I think of cloud computing I think of… computing as a utility… on
demand computing… a pay as you go model for computing resources…
and SaaS – software provided as a service, versus being installed on a
computer on my desk or in my facility.
Computing resources and software applications delivered by the cloud are receiving a lot of attention, and for good reason. The cloud-based model provides a new and different approach for the delivery of software applications and offers a range of benefits including:
As we discuss the emergence of cloud-based solutions in the BAS
industry, however, it is important that we take a lesson from the past
and not fall victim to technology blindness. Like most new
technologies, the cloud offers new ways to do things and new cost
models that are very appealing for certain applications. Cloud
computing is not a panacea for every challenge, every customer or every
It simply won’t be all or nothing when it comes to the use of the cloud model. Web-based applications did not eliminate the need for fat client software, and no single standard protocol replaced all others. The situation with cloud computing and software delivery via a hosted SaaS model is similar.
Some of the issues that affect the applicability of the cloud model include:
So in our excitement to take advantage of the benefits of this new technology (of which there are many), I hope that we do not adopt a view that the only way to do things from now on is with cloud-based software. Rather, let's be sure to match the needs of the specific project to the software delivery approach that provides the best fit for the customer. Let's leave the “religion” behind this time. It’s clear that we have a great tool in cloud computing – but everything out there is not a nail.
