Diversify or die -- that's the lesson of the era for most any service-oriented company. If you don't want to get plowed under, you'd better find out where else you can go from here.
Salesforce is hardly in danger of getting plowed under, but it isn't waiting around for the plow to arrive either. Today the company added to its product portfolio Salesforce Identity, which it bills as "Identity for the Connected World." Salesforce Identity promises to allow both customers of and employees within a Salesforce-powered company to use any of a number of common identity platforms for "any app, on any device." It also puts Salesforce that much more in competition with Microsoft's Windows Azure-based identity offerings -- or maybe it's the other way around.
Salesforce Identity is Salesforce's proffered solution to what it calls the "identity silo" problem, where users and customers alike are stuck navigating multiple identity frameworks. Enterprise users can't use their Active Directory sign-ons to work with their cache of Google apps, and customers would rather use an existing identity service -- one they might well already be logged in with -- than create entirely new accounts for each app.
Salesforce Identity intends to solve these problems with a ready-made solution -- one, most important, that's not just for Salesforce customers. Aside from being able to sign into Salesforce and all apps built with the platform via a whole mix of credentials, many common open identity standards are also supported (SAML, OAuth, OpenID Connect, SCIM), and enterprises can also set up their own branded log-in portals for their customers.
What's striking is how Salesforce isn't going to restrict this to just its own clients. Salesforce's plan is to allow free use of Identity for existing Salesforce Enterprise and Unlimited customers, and to charge $5 per user per month for access to the service by everyone not using Salesforce. Another $1 per user per month is charged to add the connector for existing identity directories such as Active Directory, though.
