IaaS and the rise of As-a-Service

blog Friday, February 11, 2022

Nowadays it seems as if every letter of the alphabet has its own "as-a-Service" model. The emergence of these IT service models has been around for some time, however all kinds of related services are slowly getting their own abbreviation.

Infrastructure as-a-Service

Terms like IaaS, PaaS and SaaS are household names within the IT landscape. But have you ever thought about the actual definition of these different terms? Let's explain exactly what an IaaS provider is, in order to understand the related service models. This will make the differences between IaaS, PaaS, or SaaS providers crystal clear.

Given that the IT landscape is always evolving, this blog may not provide a complete picture in the long term. It provides guidance on whether you should choose an IaaS, PaaS or SaaS provider. So that your IT services can be aligned with the right service model. Only when you have a clear picture of what an Infrastructure as a Service provider can offer, can you make a well-considered decision. So you can shift your focus to the core of your organization. And the IT department can seamlessly integrate its knowledge with the provider's expertise.

Very strictly speaking, offering Infrastructure as-a-Service, or IaaS for short, is making fundamental computing resources, like storage and networks available as a service. Generally speaking, this is offered on a fixed price per month. The result is that organizations can develop and run software as they wish. These examples of software include but are not limited to operating systems, applications and data management. The IaaS provider is responsible for the data center facilities including the storage, compute, and network layer. So that the entire infrastructure, or technical backbone of an organization, can be purchased as flexible as possible. Without having to invest in equipment and knowledge yourself.

The IaaS service model

  • Physical machines such as dedicated servers are deployable for necessary computing.
  • Storage, facilitating data archiving, and backups.
  • Network management, including routing, interconnectivity, and uptime guarantee.

Platform as-a-Service

With PaaS, as the name suggests there is a complete platform available in which IT services can be developed and exist. The services developed on such a platform are usually the product of a so-called SaaS provider.

Platform as a Service is a cloud service model that can be described as offering an environment (platform) where software applications can be developed, tested, delivered and managed. The basis is a cloud infrastructure that can be used by the user, usually developers, to quickly implement applications. The advantage is that the user does not have to worry about managing, controlling, or securing the underlying cloud infrastructure. The network, the physical servers, operating systems, or storage are not visible. There is control over the implemented applications and possibly configuration settings for the environment where the application is hosted. PaaS is designed so that you can easily and quickly host mobile apps or web applications, without having to set up and maintain an entire infrastructure for it. In short you only have to deal with application management & data management. 

Software-as-a-Service

When we discuss software as a Service (SaaS), we are generally talking about parties that offer applications (software) that ultimately lean on a cloud infrastructure. Often on a subscription basis. These applications are accessed from, for example, a web browser (such as web-based email), or an application interface. The provider usually does not manage or control the underlying cloud infrastructure. Examples of well-known SaaS providers are Freshworks, Adobe, and Zoom.

With a SaaS company, you (usually) don't have to worry about:

  • Application management
  • Data management
  • Runtime management
  • Middleware
  • Operating system
  • Server Virtualization
  • Server Management
  • Storage Management
  • Network management

The choice between IaaS, PaaS and SaaS

When an organization switches to a service model such as IaaS, PaaS or SaaS, the main reason seems to be moving from capital expenses and towards operational expenses. Or in other words, a fixed cost per month. Ask yourself: where does my knowledge lie as an organization? Then you can use the above to make an informed decision. So that the knowledge of your IT department coexists with the promises of said service model. In addition, another dimension plays a major role, namely where your competition is heading. Gartner predicts that the global market for IaaS will grow to $106.8 billion in 2022. For SaaS and PaaS, that's $145.37 and $71.5 billion respectively (rounded). In short, with a fitting strategy, it can help bring in new partners, cut costs, and give you a competitive advantage.
