Addressing Technical Debt

Technical debt is a term borrowed from the world of software development. It refers to the cost of short-term solutions and compromises made to meet immediate goals, which ultimately result in long-term cost to system maintenance and scalability. Technical debt is not limited to software development, and IT infrastructure technical debt is a growing concern for many organisations. This article explores what IT infrastructure technical debt is and the impact it can have.

What is IT Infrastructure Technical Debt?

IT infrastructure refers to the hardware, software, and network components that enable a business to operate. IT infrastructure technical debt is the accumulation of short-term decisions which do not consider the impact on infrastructure long term. Technical debt can arise when an organization does not keep pace with changes in technology or invest in modernizing IT infrastructure. The accumulation of technical debt over time results in more resources being used to maintain systems and less on improving them. This leads to yet more technical debt.

Technical debt can often be a result of underinvestment in IT infrastructure or neglect of infrastructure maintenance. This often leads to a reliance on outdated technologies and legacy systems that are difficult to maintain and update. As a result, the organization may face operational inefficiencies, security vulnerabilities, and increased maintenance costs.

The Impact of IT Infrastructure Technical Debt on Businesses

IT infrastructure technical debt can have a significant impact on businesses. Here are a few examples:

  • Increased Maintenance Costs: Outdated infrastructure components require more maintenance, which can result in higher costs. Legacy systems often require specialized skills and knowledge to maintain, which can make it difficult and expensive to find qualified personnel to support them.
  • Security Vulnerabilities: Legacy systems often lack the security features of modern systems, and may be more vulnerable to cyberattacks and data breaches. This can result in loss of sensitive data and damage to the organization’s reputation.
  • Inefficient Operations: Outdated infrastructure can result in slower performance and reduced productivity. This can impact customer satisfaction and result in lost business.
  • Reduced Agility: Legacy systems can be difficult to modify or update, which can limit the ability to adapt to changing business requirements. This can result in missed opportunities and reduced competitiveness.

In extreme cases a lack of vendor support, if the vendor still exists, or loss of access to key source components may make it impossible to maintain or secure these systems.

Addressing IT Infrastructure Technical Debt

Addressing IT infrastructure technical debt requires a comprehensive approach that involves both short-term and long-term solutions. Here are a few steps that organizations can take:

  • Conduct an Infrastructure Audit: Conduct a thorough audit of the organization’s IT infrastructure to identify legacy systems and outdated components. Commercial auditing tools can help here, as can some cloud migration services such as Azure Migrate.
  • Prioritize Upgrades: When looking to upgrade infrastructure, many organisations look to upgrade the least critical services first to reduce risk. However, the risk of change needs to be balanced against the risks posed by the technical debt itself. Prioritizing upgrades based on the criticality of the infrastructure component and the potential impact of an outage or failure can be the better approach if the accumulated risk is already high.
  • Invest in Modernization: Update IT infrastructure to ensure that it is scalable, flexible, and can support the organization’s long-term goals. Many organisations are looking at hybrid cloud computing to meet these challenges.
  • Implement Best Practices: Implement best practices for infrastructure management, such as regular maintenance, monitoring, and documentation.

Regular reviews of documentation and key processes are vital to avoid unplanned outages, protect against data loss, and enable swift recovery if required. Monitoring should be appropriate in both breadth and depth of coverage, and generate useful notifications with a high signal-to-noise ratio. If a robust monitoring solution is not already in-place then cloud services can fill the gap, using products like Microsoft Azure Sentinel.


IT infrastructure technical debt can have a significant impact on businesses. Organizations that neglect their IT infrastructure or rely on outdated systems face increased maintenance costs, security vulnerabilities, and reduced agility. Addressing IT challenges in a timely manner helps to control the operational cost of IT infrastructure, reduce the risk of unplanned outages, and improves the success rate of future innovation.
