CMDBs, or Configuration Management Databases, are a powerful tool for enhancing IT environments. They allow managers to track and manage the configuration of all devices in an enterprise network. CMDBs provide a single source of truth for device information, which helps improve communication and collaboration among different teams in an organization. CMDBs provide you with a layout of all of your IT assets and show you how they relate to one another, making them indispensable. When used correctly, it allows you to respond rapidly to changes in your business environment and plan your asset lifecycles more easily.
CMDBs also help automate tasks and improve incident response times. However, few CIOs and CTOs are leveraging their full power despite their potential because CMDBs can be complex and expensive to implement.
Below, we explore the benefits of CMDBs and some drawbacks to consider.
Configuration management databases are designed to store an enterprise’s IT infrastructure data. This data can include information about assets, such as hardware and software, and configurations, such as network settings and application versions. CMDBs typically use a relational database management system (RDBMS) to store this data.
Creating a configured database enables companies to obtain the information they need to make better business decisions and execute IT Service Management (ITSM) processes more effectively. Configuration items (CIs) is the term used to describe items tracked in a CMDB.
All configuration information is stored in one location, which leads to a deeper understanding of the CIs and their connections. Impact analysis, root-cause analysis, incident management, change management, and legal compliance are all simple to handle. A CMDB helps system administrators improve their ability to solve problems, react to incidents, develop plans, and improve overall decision-making.
What is the Difference Between a CMDB and IT Asset Management?
Given the similarity in some aspects, it isn’t surprising that many IT professionals confuse CMDBs with IT Asset Management (ITAM) databases. While both systems track data about an organization’s hardware and software, CMDBs focus on configuration data while ITAM tools focus on asset lifecycle data.
CMDB configuration data refers to devices and systems’ specific settings and parameters within an enterprise network. This data can include information about the make, model, and the serial number of a device and its IP address, operating system, and version.
In contrast, IT Asset Management management deals with the physical aspects of IT assets such as location, ownership, and cost. ITAM tools track an asset’s purchase date, warranty information, and depreciation schedule. CMDBs don’t track this type of information, but IT managers can integrate them with ITAM tools to provide a complete picture of an organization’s IT infrastructure.
Characteristics of CMDB Tools
There are five main operations characteristics of a CMDB tool:
- Populating and updating CI data: CMDB tools must be able to collect data from multiple sources within an enterprise network and populate the CMDB with this data. The data can be entered manually, via API integration, or through automated discovery.
- Classifying CI data: These tools use classification schemes to categorize CIs. These schemes help simplify the process of viewing and managing large amounts of data.
- Storing CI data: CI data is stored, accessed, and updated by authorized users.
- CI data visualization, metrics, and analytics dashboard: CMDB tools allow users to view CI data in a variety of formats. Monitoring all CIs, their inter-dependencies, and correlations is essential to maintaining system integrity. It’s easy to notice problems and close gaps in a topological bird’s eye view of the system.
- Access control: CMDB tools offer granular control over who can access CI data and what type of data they can view.
Benefits of CMDBs
Data silos and out-of-date knowledge stymie the decision-making process, so a CMDB seeks to address these flaws. In general, organizations maintain a variety of data sets across several systems and channels, making it nearly impossible to understand what data is most important.
Against this background, the following are the most notable benefits of CMDBs:
- A CMDB can help you manage change by providing a complete view of all CIs and their relationships. This information is essential for planning and executing changes to your IT environment.
- It can improve incident management by providing visibility into the configuration of devices involved in an incident. This information can help you troubleshoot incidents more quickly and resolve them more efficiently.
- A CMDB can help you plan for future growth by providing information about the capacity and utilization of your IT assets. This information can help you decide when to add new assets to your environment and how to utilize existing assets best.
- It can improve compliance with regulatory requirements by providing visibility into the configuration of devices in your environment. This information can help ensure that your devices are configured correctly and meet all relevant compliance requirements.
Are There Any Drawbacks to CMDBs?
Despite the many benefits of CMDBs, there are some drawbacks that you should be aware of:
- Skillset and knowledge: The most common challenge is that CMDB tools require professionals to have the right skillset and knowledge to use them effectively. CMDBs can be difficult to use if you don’t have the right tools or training. But, on the flip side, you need the right expertise to choose the best tool for your needs.
- Complex and expensive: CMDBs can be complex and expensive to implement, especially if you don’t have the internal resources to do it.
- Need ongoing maintenance and continual updates: CMDBs require ongoing maintenance and continual updates to keep them accurate.
- Work culture and commitment: CMDBs require a change in work culture and commitment from everyone in the organization to be successful. According to a recent study by McKinsey, 70% of digital transformation efforts fail due to employee resistance, poor or nonexistent cross-functional collaboration, inadequate management support, and a lack of accountability.
Getting Started with CMDBs
The biggest challenge to getting started with CMDBs is usually the lack of in-house expertise. You must be mindful of the potential knowledge gap. It takes extensive technical experience and expertise to understand CMDBs, and there is often a deep chasm between experienced staff and C-Suite business leaders. In a typical scenario, the CMDB tool(s) quickly becomes a white elephant—dormant, unused, ineffective, and at a great cost.
To get the most out of the CMDB, you’ll need to engage in regular, collaborative discussions with business executives. If IT and corporate collaborate on broader planning rather than just one-off projects, the company can establish a vital and vibrant decision-making database that is available in a visual format so that everyone may see the links across its IT landscape — allowing for greater agility.
Despite the drawbacks, CMDBs offer many benefits that can improve the efficiency of your IT processes. If you’re considering implementing a CMDB, start by evaluating your needs and determining whether a CMDB would be a good fit for your organization.
Once you’ve decided to implement a CMDB, work with an experienced implementation partner who can help you get the most out of your investment.
