Identity Provider as a Service

The “as-a-service” model has transformed the IT market with its ease in scalability and lower upfront costs. While the Infrastructure-as-a-Service and Software-as-a-Service markets have grown in development and maturity, IT admins can’t help but ask if there is such a thing as an Identity Provider as a Service? The good news is that there is. Called Directory-as-a-Service®, the cloud identity management platform is a cloud identity provider.

The IT landscape at the time was primarily Microsoft Windows based and hosted on-prem. So of course the identity provider would be Windows-based and on-prem as well. Active Directory took the model of direct connect, which means that a system or application couldn’t authenticate unless there was a direct path between the IT resource and the identity provider. At the time, these requirements made a great deal of sense. It also made IT admins feel more secure with the identity provider behind their firewall and within their control.

Then, the IT network started to change. Microsoft Exchange morphed to hosted email solutions such as Google Apps (now G Suite) and Office 365. Data centers turned into cloud infrastructure hosted at AWS and Google Cloud Platform. Web applications became more popular and the wired networks switched to WiFi. All of these changes put tremendous pressure on the on-prem identity provider, Active Directory, but Microsoft wasn’t eager to integrate these new non-Microsoft resources with Active Directory. So, for a long time IT admins had to enlist insecure or expensive solutions to connect users to web-based applications (Read more...)
