What is Cloud IAM?

what is cloud IAM

What is Cloud IAM? In short, it refers to the ability to manage user identities and their access to IT resources from the cloud. Why should cloud IAM be a priority? To answer that question, let’s take a look at the evolution of traditional identity and access management (IAM) solutions and compare them to cloud alternatives.  

Evolution of Identity and Access Management

evolution of directory servicesIAM solutions have been a foundational component of IT infrastructure for many years now. In fact, the modern era of IAM dates back to 1993, when Tim Howes and his colleagues at the University of Michigan introduced the Lightweight Directory Access Protocol (LDAP). LDAP was designed as a lightweight replacement to the Directory Access Protocol (DAP), which was a component of the forerunner directory services standard known as X.500. LDAP worked so well that LDAPv3 would become the internet standard for directory services in 1997, and directly influenced two powerful IAM platforms: OpenLDAP and Microsoft® Active Directory® (AD).

Today, we know that Active Directory has been far more dominant than OpenLDAP in the IAM market. Of course, this is primarily because Microsoft Windows® was effectively the only major enterprise operating system in use in the late 1990s, when both AD and OpenLDAP were introduced. At the time, it was common for all of the systems, applications, files, and networks in an enterprise IT environment to be Windows-based, which gave AD a built-in advantage. In most cases, IT simply implemented AD, and they could basically manage all of the users and IT resources in their environment.

The IT landscape started to change when a wide variety of non-Windows resources were introduced in the mid-2000s. This included Mac® systems, web applications like Google Apps (aka G Suite), Linux® servers at AWS®, Samba file servers and NAS appliances, and a lot more. Even the network itself switched from a wired connection to WiFi. All of these changes and more have rendered legacy solutions like AD (and OpenLDAP) far less effective in the modern enterprise.
