In a podcast last year, Dana Gardner, along with Anrai O’Toole, explored the possibilities of what is often referred to as “Integration as a Service.” A few months after his podcast with Dana, Anrai practiced what he preached — his company, ESB provider Cape Clear, offered up its ESB into the cloud. The company was absorbed into Workday, an online ERP provider, earlier this year.” “SOA tools and platforms from the cloud is certainly something that would be appealing for smaller organizations that lack the time and expertise to undertake SOA efforts, and don’t have the luxury of maintaining something akin to a SOA center of excellence.” Joe gets it, but kind of misses my point. I’m really not looking for SOA vendors to SaaS-enable their technology, but for those vendors to sell the technology differently — out of the cloud or not. Indeed, this means paying for performance, or collecting the money only when the technology has lived up to expectation. The best way to do that is by using a subscription model. If these guys want to continue to hug their on-premise servers, that’s fine, but it’s still a subscription model. If they want to consume the technology out of the cloud, that’s fine as well — also a subscription model. The core notion is that you need to provide the value today, and going forward. Subscription models are great for that because if they don’t provide the value, you simply cancel. To date, only those who currently offer a subscription model are accepting the “Pay-as-you-go SOA Challenge.” Those who still rely on license revenue are awfully silent on this matter. I suspect that won’t change. Software Development
