What does IT Landscape Diagram mean?
What is an IT Landscape, IT Landscape Diagram, IT System, or Technical Diagram? Read the Dragon1 Term Definition.
A new term has entered our organizations in the last ten years. First, just a few, but many large to medium enterprises (LMEs) now have an IT landscape or technical diagram on their premises to manage IT risks. But what exactly is an IT landscape, what does landscape mean, and why do organizations (should) have or use it?
Landscape Definition
An IT Landscape is a Dragon1 architecture drawing, at a physical, logical, or conceptual level, showing the structure and workings of IT and delivery of services in an organization, with its systems, tools and processes.
In more detail, an IT landscape diagram is the visualization of the types of available IT Assets of an organization, i.e. the set of computer software and hardware plus 'connected' things. Arranged in a specific configuration that serves as the current IT Infrastructure to support the business operation of an organization, preferably in an optimal way.
An IT Landscape Diagram presents a technical view of IT and not a functional view. Therefore, the organization's information systems are often not visible or clear in the IT Landscape. Although the diagram may show many parts of the Information Systems.
Example IT Infrastructure Blueprint Diagram
An example visualization of an IT Infrastructure Blueprint is below. You see an overview of the type of assets and the actual assets. Not the concepts, principles, rules, or standards.
IT Legacy and Innovation
As every IT Landscape is created over a period covering different IT Technology ERAs, it is exciting to see the legacy and new IT systems in your IT Landscape. This situation increases the complexity of your IT Landscape and should be managed well. Things can get complicated, especially where the old and new IT systems connect. Create an IT Landscape Diagram to get an overview and use it to manage the risks.
Saving Costs with an IT Landscape Diagram
Two well-known ways of saving costs using an IT Landscape Diagram are:
1. Knowing when the end of life of IT assets will be is important to prevent disinvestments. This means you only replace IT assets when fully worn out and not before the end-of-life date.
2. By standardizing and normalizing your IT assets, the complexity will be reduced, IT issues will decrease, and the necessary IT asset knowledge for IT service management will be reduced, leading to lower costs for your IT Landscape.
IT Landscape vs IT Infrastructure vs IT Architecture
An IT Landscape Diagram shows an overview of all the IT assets of the organization, only with less detail than an IT Infrastructure Diagram. An IT Infrastructure Diagram would show the actual assets, and an IT Landscape is about the type of assets. It is also not an IT Architecture Diagram. An IT Architecture Diagram shows the concepts, principles, norms, standards, and guidelines to which the IT Landscape must or should comply.
An Application Landscape Diagram can be seen as a subset of the IT Landscape Diagram, focusing on applications only.
IT Management using the IT Landscape
IT Management has a lot of benefits from having an IT Landscape available. Below, we mention three common benefits:
- Improving business information management
- Seeing the end of life of applications and other resources, so you know when you can renew or innovate your IT Infrastructure.
- An overview of on-premise source versus outsourcing (SAAS-based) services.
Uncommon but getting more popular is visualizing the IT security measures and other processes in the IT Landscape Diagram. What you do is visualize the process of monitoring and risk management concerning a certain IT asset, like how often a firewall is checked on policy compliance.
Online Real-Time View of the IT Landscape
Today, organizations need to be able to react quickly to situations and issues. With that, the need for an online real-time IT Landscape arises. Dragon1 provides you with the ability to have an online real-time IT Landscape Diagram available.
Why don't all Organizations have an IT Landscape Diagram?
Four reasons often play a role in an organization not having an IT Landscape Diagram and thus spending more time, money, and resources on IT assets than necessary:
- There is not enough knowledge in the form of IT architecture present in the organization
- Organizations are caught up in strategic change, so no one has time to be busy with creating an IT Landscape Diagram
- The IT Landscape is (thought to be) too complicated to be put in a single overview
- The organization does not have all its tactical (business information management) processes. When costs on IT assets are reported, an IT Landscape Diagram is either easy to create or used to calculate the costs.
