Configuration Items or CIs are the building blocks that make up business services. Managing them effectively is a key activity of the Configuration Management process, which looks to make sure these components are accounted for and reliable information on them is available. It lays the groundwork for trustworthy service operations.   

The most widespread practice to do this is by building a Configuration Management Database (CMDB) that sets out your CIs and their relationships. So, join us as we define the full scope of Configuration Items and explain how to manage them effectively on InvGate Insight

Ready to learn more about CIs? Let's get started.


What is a Configuration Item?

The Configuration Management practice has a lot of terminology, so let's start with the basics. ITIL defines a CI as any component which needs to be managed in order to deliver an IT service.

In simpler terms, it can be thought of as any identifiable and manageable element that contributes to the functioning of an organization's IT environment. This can include hardware, software, network equipment, buildings, suppliers, and documentation – that is, anything that can make up part of an IT service.


Asset vs. Configuration Item

Assets and CIs are dealt with in the ITIL framework. They are both key components that must be kept under your radar and help you efficiently manage your IT environment. However,  there are key differences between the two to consider. Let’s take a look.

  • A CI is a building block within an organization's IT infrastructure and includes any components that need to be managed and controlled to ensure the delivery of IT services. The focus of CIs is on their impact on delivering stable IT services and their relationships and dependencies with other CIs throughout an organization. The CMDB stores and manages information about CIs and their relationships.

  • An asset refers to any item that has value to an organization and can contribute to its financial status. The focus of assets is on their monetary value and management and IT Asset Management (ITAM) involves the lifecycle of the financial aspects of assets, such as procurement costs, maintenance, depreciation, and disposal.

Configuration Item types (and subtypes)

We’ve set out the criteria to define what a CI is in each organization, but you might still be wondering what this looks like exactly in real life.  So, some typical CI categories and examples include:

Hardware CIs:

  • Servers (both physical and virtual)
  • Storage devices (disk arrays, storage area networks)
  • IoT devices
  • Network devices (routers, switches, and hubs)
  • Voice equipment (PBXs and IVR systems)
  • Printers and scanners
  • End-user devices (laptops, desktops, mobile devices)

Software CIs:

  • Operating Systems 
  • Business applications such as your Office suite
  • Custom software applications 
  • Software licenses
  • Middleware 
  • Utilities such as system backup tools and anti-virus software

Network CIs:

  • IP addresses and subnets
  • LAN, WAN, and VLAN information
  • Firewalls 
  • Gateways
  • Wireless access points
  • Network bridges
  • Network segments
  • DNS (Domain Name System) configurations 

Documentation CIs:

  • User Manuals
  • Design Specifications
  • Configuration and Installation Guides
  • Network Diagrams
  • Process Documentation
  • SLAs, OLAs, and XLAs

Facility Configuration Items:

  • Data centers, comms rooms, and server rooms
  • HVAC (Heating, Ventilation, and Air Conditioning) Systems
  • Battery and backup systems, for example, UPS details
  • Power Distribution Units (PDUs)
  • Physical security systems

Supplier CIs:

  • Vendor contracts and agreements
  • Supplier information and contact details
  • Information from your supplier and contracts database (if you have one)

Technical service CIs:

  • Internal CIs (i.e., project assets)
  • External CIs (i.e.,  customer agreements) 
  • Interface CIs )i.e., details how an end-to-end service is delivered through APIs and service provider interfaces)

Configuration item attributes

CI attributes are the characteristics that describe and define a specific CI within your IT infrastructure. Attributes provide details about the CI, its specifications, what makes it part of the service provision, and the relationships between them. 

By clearly defining them in a CMDB, you have access to a map of how everything operates and relates with each other in your environment. This provides valuable information to support your IT functions. 

Some common types of CI attributes include:

  • Unique Identifier
  • Name or label of the CI
  • Brief description of the CIs purpose
  • Type, for example, hardware, software, documentation
  • Subtype, for instance. Server, finance application, network documentation
  • Model or version number
  • Support Details
  • Vendor Details
  • Owner
  • Relationship to other CIs and services, for example, parent and child relationships
  • Location (physical and logical)
  • Status
  • Cost and financial information
  • Warranty information
  • Security requirements, if appropriate
  • CI abbreviations or acronyms

Configuration item lifecycle

The CI lifecycle refers to the stages a CI goes through within an organization's IT environment. Effective management ensures that CIs are properly managed, controlled, and maintained throughout their lifecycle in line with corporate requirements. 

The process typically includes the following stages:

  • Planning and design - Identifying the need for a new CI is the main part of the requirements-gathering exercise that kicks off the process.
  • Acquisition and procurement - Procuring or creating the CI according to the design specifications.
  • Identification and registration - Assigning the CI a unique identifier and registering it in the CMDB.
  • In test environment: - Ensuring that it functions as required and meets quality standards.
  • Deployment - Releasing it to the production environment and made available to end users.
  • Early life support - The warranty or settling-in period may include enhancing support levels and response times when a CI has been recently deployed to the live environment.
  • Production environment - Performing the monitoring, management, maintenance, and updates required to keep the CI running effectively and efficiently.
  • Retirement and Disposal - When the CI is no longer needed, the retirement and disposal process involves ensuring any data is removed, redeploying any related software licenses and recycling or disposing any hardware components.

Configuration Item Management

It's time for more terminology! As we mentioned, the best way to stay on top of your practice is to incorporate a robust tool with specific Configuration Management features. 

In this sense, CIs are managed most effectively in a CMDB or CMS environment, so let's take a minute to understand how this works:

  • The CMDB is a database that stores configuration records throughout their lifecycle; which also maintains the relationships between configuration records. In other words, it captures the CIs that makeup IT systems and how they work together to deliver business services.

  • The CMS is a set of tools, data, and information for Service Configuration Management. It can be made up of multiple CMDBs, asset databases, and knowledge information.

A CMDB or CMS is only as good as the data it contains, so it is good practice to create checkpoints within your Configuration Management activities to ensure your CI information is up to date and accurately reflects your IT environment. Some examples include:

  • Ask your service desk analysts to categorize incidents and service requests using the CMDB. They can also update incorrect CI data when logging tickets.
  • Ask support teams to raise changes with the impacted services flagged into the database. 
  • Ask your Change Enablement teams to impact assess change against the service information in the CMDB. You can also request success criteria that support Configuration Management; for example, a change can only be closed off as successful when the service information or CI is updated. 
  • Ask your Release Management teams to deploy releases based on CI information and check for accuracy.
  • Ask your Problem Management team to use the CMDB to support problem and known error analysis.
  • Ask your service catalog teams if the CMDB would be useful in identifying IT services.
  • Work with your security teams to ensure that any security incidents are automatically linked to a CI so they can be managed more effectively.

How to manage CIs on InvGate Insight


So, let’s see how ITAM software can streamline this process. On InvGate Insight, Configuration Items are tracked and managed through the CMDB feature. 

The first thing you have to do is incorporate your CIs into the system. This can take the following formats:

  • Assets: Installing an Agent, through the Network Discovery feature, or by uploading a .csv file.
  • Users: Creating them in Settings >> General >> Users or by integrating the tool with Active Directory or Microsoft Entra ID (formerly Azure Active Directory).
  • Locations: Creating them in Settings >> General >> Locations.
  • Contracts: Creating them in New CI >> Contract >> Assets.

Apart from the individual CIs that make up your environment, you can also map out their relationships by creating Business Applications. These are groups of related CIs that serve a purpose together. InvGate Insight provides you with an intuitive diagram editor to visually represent them on your instance. 

And there you go. In the CMDB section you will find all the relevant information regarding your CIs, including a comprehensive map with statistics and activity information.

In short

Each organization defines its own Configuration Items depending on what they consider necessary to run their IT services successfully. This includes assets, but also locations, users, documentation, suppliers or any other relevant IT information. 

These components are usually managed in the CMDB that maps out the CIs and their relationships to make sure you can keep track of them throughout their lifecycle. But you can’t do this without the right tool that incorporates Configuration Management processes.
