The more things change, the more they revert to where they started from. Computing started off as one central mainframe computer with a lot of dumb terminals attached. Then came distributed computing with one central mainframe and several mini computers attached. This was followed by personal computing and now mobile computing. However; the mainframe never died contrary to popular propaganda. It simply evolved and we now give it trendy names like cloud computing and SaaS.
Both Cloud computing and SaaS are here to stay as customers today have more choices and don’t want to pay for the functions and features they don’t need or the mega MIPS they don’t use. And that is what makes SaaS products such a good deal and will continue to be as security improves and international laws about cyber security gets formulated and implemented. SaaS products have reduced margins per customer for the software developers but they can engage a larger client base due to the ease of delivery and greater reach. They earn a little over a larger customer base resulting in greater net profits.
Technology is evolving in such interesting ways. SaaS products like http://UploadMyProducts.com now synchronize your product database with multiple marketplaces like Amazon, eBay, Rakuten etc. in one go. Saves you the hassle and time of doing it one at a time. QuickBooks that evolved with personal computing has moved to a SaaS model though they continue to have a strong native PC presense. If you are a user of software and services, stay tuned. More good things are going to come.
