The Enterprise System Spectator

Over the past few years, salesforce.com has been gradually morphing itself from an on-demand CRM vendor to a platform for software-as-a-service (SaaS) generally. It started by first allowing extensive customer-specific customization of its CRM applications and integration with legacy or third-party systems. Then it provided a complete development environment, including test capabilities separate from production. Then it opened up its SaaS platform to third-party developers to write complementary applications. This week it announced the next logical step: it is allowing customers to buy access to its platform without buying its CRM application.

Salesforce.com Platform Edition allows customers to take advantage of other applications in its AppExchange marketplace, or, it allows customers to start from scratch and write their own custom applications. Details on Platform Edition are on the salesforce.com website.

The evolution of salesforce.com further enhances software-as-a-service as a viable alternative to traditional on-premise software. The only drawback to this approach I see is that it ties the entire IT infrastructure of the customer to salesforce.com. If you think vendor lock-in is a problem today with traditional vendors, such as Microsoft, Oracle, and SAP, imagine what it will be like when your entire technology stack--from hardware, OS, database, and application--is tied to a single provider.

I'm a big fan of SaaS, but I still haven't figured out how to get around the vendor lock-in problem.
