Re: Missing the point
TerryB, you're failing to mention all the headaches associated with running ERP on-premises. All the running of infrastructure, the patches, the periodic updates, and, worst of all, the inevitble full-system software upgrades. With a true SaaS service (not hosting of conventional software) you sidestep all of that. What's more, you can't count on on-premises stabilty. The world changes -- laws, regulatory requirements, etc. -- and business changes -- users, departments, products, partners, etc. -- so "stability" is a myth.
Our company just did a E-Business Suite upgrade, and every week, it seems, we're still getting multiple emails from IT about service outages and planned downtime for maintenance and administrative tasks. SaaS services aren't perfrect, but I'd wager vendors under pressure from hundreds to ensure SLAs are better able to do it than most IT departments under pressure from one employer or shared-services honcho.
