What is Infrastructure-as-a-Service (IaaS)?

The term Infrastructure-as-a-Service (IaaS) refers to a category of IT solution that offers virtual computing services and infrastructure applications from the cloud. Some of the most notable vendors in the IaaS space include AWS®, Azure®, and GCE.

IaaS solutions enable IT organizations to shift various aspects (or the entirety) of their on-prem or collocated data center to the cloud. Thus, eliminating the need to purchase hardware and manage ongoing infrastructure operations in house. With IaaS, IT admins simply purchase the compute, storage, and infrastructure application resources needed to support their specific environment, and the rest operates virtually.

Cloud infrastructure is critical to IT organizations in the modern era. As IT organizations search for ways to move faster and more cost-effectively, eliminating the need to implement and maintain a complicated on-prem network or data center can be a game changer.

The issue with Infrastructure-as-a-Service solutions has historically been that controlling user access to remote devices and applications can be difficult. It traditionally requires a variety of siloed identity management solutions and heavy investment into connecting these remote resources to on-prem identity management infrastructure.

Of course, that is no longer the case now that the JumpCloud® Directory-as-a-Service® platform has come to market.

The Rise of Infrastructure-as-a-Service

Prior to the rise of IaaS in the early-2000s, almost all of IT infrastructure was on-prem (or connected via VPN) and the majority of it was based on the Microsoft® Windows® operating system (OS). This enabled IT admins to leverage Active Directory® (AD), Microsoft’s on-prem identity management platform for Windows-based networks, to manage user access to virtually all of the domain-bound IT resources in a given environment at the time.

While AD was certainly effective at managing old school networks of Windows-based IT resources, the challenge became that IT networks started to shift around the turn of the century as a number of new innovations came to market. Many of these new innovations were not Windows-based and they were delivered “as-a-Service” from the Cloud, as it is known today, which included the concept of (Read more...)
