Amazon has made a really smart move by releasing DevPay. They have in effect created a SaaS (Software as a Service) platform (EC2 / S3 / SimpleDB / ASQS) for others to build SaaS products in. They also provide those SaaS companies (or providers) with a utility mechanism for charging their customers.
It's highly seductive sales story, you can imagine the sort of pitch:
Not only do we minimise your risk and the costs associated with infrastructure start-up and scaling but we also provide you with a simple mechanism for charging your clients. If no-one uses your creation, it costs you nothing and the more people use your service then the more you get paid.
Yes please, I'll buy one .... wow ...... wait. There's a huge gotcha here. Before EC2 / S3 / SimpleDB or DevPay, I was involved in Zimki and we covered the same ground.
Let's say you use DevPay and you decide to take your system out of this environment. Unless DevPay is an open service, then along with any migration costs you are going to have to build a payment service, create a mechanism of charging and then explain this to your customers. That's a lot of pain.
OK, but why would I wish to leave such a wonderful service?
Well the ability to easily leave a service and move to another service is what maintains competition in a market place, thus ensuring that prices for a commodity remain competitive. Now the nightmare scenario for any future SaaS provider is :-
- To have their systems provided on a utility computing cloud.
- To be in competition with other SaaS providers on the same or on different utility computing clouds
- To not be able to move from one cloud to another.
In such a scenario, as a SaaS provider you NEED to enforce lock-in on your customers. If your customers can move services freely (which they will want) then you will face price competition, however since YOU cannot move services freely then your supplier doesn't face price competition.
Eventually all your prices will probably end up matching your suppliers and all your profit would hence be given away in price competition. The Warren Buffet Loom story is a worthy read here.
We considered this scenario for Zimki and the use of a utility billing service to create lock-in. We believed you could even open source everything else and create lock-in with this one little piece. Of course, if you want to create an ecosystem of providers and disrupt a whole industry then you need to open source everything.
Amazon is now that industry.
The last thing to note with a utility charging service, is that it can provide a very useful way of identifying revenue potential of any company using the service. Ideally for the provider of a utility charging service, you want customers of SaaS systems who are billed through your service to be able to sign up to multiple SaaS providers with same account (users would probably argue for the same for reasons of simplicity). This enables the owner of the utility charging service to not only estimate the revenue potential and hence value of the SaaS companies using its service but also cross selling potential. All excellent information for use in a good acquisition strategy.
Even at this seasonal time, be thoughtful of the gifts that others bring .... especially in business.
