I am a systems architect. I wrote this white paper as a cautionary tale that simply going from a client-server architecture to a Cloud-based architecture, with all computer processing being run at a remote data center, will probably not solve all of an organization's IT issues.
I have spent the past two decades working on barcode data collection systems for manufacturers and industrial distributors as technical director of a number of software and systems integration companies.
In this white paper I trace the evolution of barcode tracking systems from simple desktop applications, through client server applications, to Cloud-based systems. Along the way, I contrast what we have gained and lost with each evolution of the technology.
I then discuss the limitations of Cloud computing for implementing barcode tracking systems for applications such as work-in-process and inventory tracking in industrial organizations.
Finally, I discuss how we can overcome limitations, such as bandwidth and reliability of the Internet, to get the best compromise available with today's technology.
