In the area of Managed IT Services, there are three primary components that require some form of mandatory and ongoing monitoring and management. These three elements are your Infrastructure, Platform, and Software. Regardless of your industry, these basic building blocks are what forms your IT system foundation and the starting point which falls under Managed IT Services.
Yes, there are. As we continue, we branch out to observe the other subsets of functions and features that seamlessly work hand-in-hand with your main components. These additional Managed IT Service components are as equally important.
Please note: All parts and elements require policies, processes, and procedures. Once instituted, mandatory and continuous enforcement, reporting, and updating are used to monitor, detect, quarantine, and manage your entire network.
As you review the list of additional units below, you may not be aware of the existence of most of them. These are the unseen elements behind the scenes that give you, your staff, or your clients an uninterrupted experience when using your devices or web browsers.
Bear in mind that each item listed below can and will affect your system positively or negatively. The thing to always remember is that continuous monitoring and management is the critical differentiator and what keeps your system healthy.
Also, be aware that technology is always evolving with sweeping advances. What was new, eventually becomes commonplace. What was commonplace, becomes outdated. What becomes outdated, may not transition. So, the obsolete will see a new transition.
For example, Infrastructure, Platform, and Software are also witnessing a transformation. From horizontal deployment to vertical; i.e., from infrastructure on a physical device to infrastructure in the Cloud, or software across a physical platform to software-as-a-service.
So, on the list above, we could also add Infrastructure, but it would then be known as Infrastructure-as-a-Service (IaaS). The same “as-a-Service” would also apply to Platform (PaaS), and Software (SaaS).
Infrastructure – In the fields of IT service management and IT management, each industry relies heavily on the IT infrastructure. The way an IT infrastructure (ITI) is defined comes down to the computer, network hardware, and facilities; all physical elements forming the ITI. This is a stripped-down and basic description of an IT infrastructure.
Platform – A computing platform is an environment in which computer programs run and in which a piece of software gets carried out. The platform might be an operating system or hardware. Computing platforms have different abstraction levels with varying amounts of detail, including runtime libraries, an OS, or computer architecture.
Software – Computer software is, at its base level, instructions that tell the computer how to work, or a collection of data. This is opposite to physical hardware from which the system performs the work and was built. Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.
Now let’s look at how our three components have evolved and transitioned to the Cloud. As a reference point, IaaS, PaaS, and SaaS have become the three main categories of cloud computing services that are also a component of Managed IT Services.
Infrastructure-as-a-Service (IaaS) – This is a form of cloud computing. Over the Internet, IaaS provides virtualized computing resources. IaaS is a Virtual Machine (VM) that doesn’t need to access a network infrastructure on a physical computing device. Within the cloud operating system, there’s room and support for large numbers of VMs. This allows for adding or discontinuing services at any time.
Platform-as-a-Service (PaaS) – This is a category of cloud computing services. PaaS provides a platform allowing users to develop, run, and manage applications. It eliminates the complexity of building and maintaining the infrastructure for the applications. PaaS gets delivered in three ways: 1) public cloud service, 2) private service behind a firewall, 3) software installed on public infrastructure-as-a-service.
Software-as-a-Service (SaaS) – This is a software licensing and delivery model. The software is centrally hosted, licensed, and offered on a monthly or annual basis. SaaS is the standard delivery model for most applications. The strategy of nearly all leading enterprise software companies was to incorporate SaaS. Business applications primarily use this model.
