I’ve already written about why I think private clouds can be a good idea. Similar arguments can be made for SaaS, and then some. A friend and I did the email-ping-pong thing and ended up with a (shortish) list of reasons why to go with a SaaS solution over an traditional on-premises solution.
- OPEX rather than CAPEX cost. The CAPEX gulp is minimised, and the ongoing costs are tied to your own operational cost (head count, etc).
- Faster provisioning. SaaS is can be up to 90% faster to deploy than on-premises solutions. (Weeks/months rather than months/years.)
- No more upgrades. You’re always on the latest version, and new features are roll out organically rather than every few years as part of a change management process.
- More focused vendor and community support. As there is only a single version in play, support efforts from the vendor and user community are focused on the version that you’re using. This also avoids the problem of getting left behind on a stale and unsupported platform (been there, done that, and have the scars to prove it).
- SaaS provides a platform that scales organically with our organization. You’re not required to invest in additional hardware, software, and provisioning processes, letting your business focus on the business.
- Reduced IT involvement. IT resources can focus on specific business problems rather than the care and feeding of the system.
- Try before you buy. Instead of a traditional big license gulp at risk, sign up for a handful of SaaS seats for a few weeks and try it out. (From @shermo1.)
