IT Infrastructure Management: What is it and How Does it Work?

Society relies on many fundamental services and systems to function effectively. Roads and public transport keep people and goods moving. Power grids supply homes and workplaces with electricity. Water and sewage systems provide clean water and sanitation. Broadband and mobile networks bring the online world to us instantly. These components, known more commonly as “infrastructure”, form the basis of everyday life. Take away or neglect one or more of these, and the whole structure is compromised.

IT infrastructure works in much the same way – albeit on a smaller scale. It refers to all the technological components that make up an organisation’s IT environment, including the hardware, software, networks and operating systems which support the delivery of IT-enabled business processes. Without proper management, this infrastructure will become inefficient, leading to downtime, business interruption and lost productivity.

What is IT Infrastructure Management?

IT infrastructure management involves overseeing and optimising the hardware, software and networks that support an organisation’s IT operations. Effective management ensures that business-critical applications remain accessible and reliable, preventing disruptions that could impact productivity and growth. Given the complexity of modern IT systems, infrastructure management is typically divided into three broad categories:

Systems Management

This type of management focuses on ensuring that all servers and operating systems are up to date, secure and compatible with each other to support an organisation’s needs and prevent software conflicts or slowdowns. This includes tasks like software updates, patch management, performance monitoring and configuration management.

Network Management

This type of management involves maintaining a stable, secure and high-performing network for an organisation. It ensures that bandwidth is properly allocated to applications and IT services, and that appropriate security measures are in place to protect against cyber threats. This includes tasks like network performance monitoring, traffic management, security enforcement and access control.

Storage Management

This type of management involves organising data storage systems to ensure that an organisation’s information is available as needed and is stored in a manner that optimises performance and security. This includes tasks such as data backup and recovery, cloud migration, encryption and lifecycle management.

Why is IT Infrastructure Management Important?

If you aren’t already managing your IT infrastructure, chances are you don’t know how your IT environment is really performing until the damage is done. Proactive management means you’ll know when security vulnerabilities need to be patched, when it’s time to upgrade technologies, when cloud resources are being under or over-utilised and more. This way, your organisation can make informed IT decisions before potential issues become critical. Additional benefits include:

• Reduced Costs: By proactively managing your IT infrastructure, your business will be well-placed to avoid costly downtime and data losses, leaving you with more money in your IT budget for more valuable uses.
• Improved Efficiency: Regular monitoring and maintenance keep systems running smoothly, reducing lag and performance issues that can slow down workflows and impact productivity.
• Stronger Security: Proactive threat detection and regular updates help protect your business from cyber attacks, reducing the risk of data breaches and costly security incidents.
• Better Scalability: A well-managed IT infrastructure makes it easier to expand operations, integrate new technologies and support remote or hybrid work without major disruptions.
• Increased Reliability: Preventative maintenance and system monitoring reduce the risk of unexpected failures, ensuring employees and customers can always access the services they need.
• Compliance Assurance: Staying on top of IT management helps businesses meet industry regulations and data protection laws, avoiding legal risks and potential fines.

IT Infrastructure Management vs IT Operations

There’s a term that has become common in IT because both elements work together to ensure service and application delivery: “infrastructure and operations” (I&O). While they complement each other in many ways, they have distinct roles within an organisation’s IT environment.

IT infrastructure management involves designing, upgrading, securing and scaling an organisation’s IT systems to ensure it meets its needs both now and in the future. IT operations, on the other hand, is an umbrella term that covers all the processes involved in the daily running of IT systems and services.

Essentially, IT infrastructure management takes a long-term, strategic approach to maintaining and improving IT systems, while IT operations focuses on keeping everything running smoothly from moment to moment.

Remote IT Infrastructure Management

According to Hewlett Packard: “Remote infrastructure management is the process of monitoring and managing IT infrastructure from a remote location with the ability to perform remedial actions to enable continuous availability.”

Remote IT infrastructure management can be implemented and managed in one of two ways: by an in-house IT team using remote access tools or by outsourcing to a third-party IT service provider. Outsourcing these processes provides businesses with access to specialised expertise without the overhead costs of hiring and training internal staff.

Centralising IT infrastructure management from an off-site location offers several additional benefits, including greater coordination, ease of maintenance, improved system performance, cost savings, quicker response time, reduced risk and increased flexibility. It allows organisations to maintain a high level of control over their IT environment while ensuring systems are monitored around the clock.

IT Infrastructure Manager

An IT infrastructure manager is responsible for the design, implementation, maintenance and eventual decommissioning of an organisation’s IT environment. Each infrastructure manager’s specific tasks can vary depending on company size, industry and infrastructure complexity, but typical responsibilities include:

• Managing IT budgets and costs.
• Coordinating between technical staff and stakeholders.
• Overseeing IT infrastructure and security to maximise availability and data protection.
• Defining, tracking and meeting KPIs.
• Setting strategic direction for IT infrastructure.
• Promoting simplification, standardisation and innovation.
• Maintaining logs, documentation and reports of activity.

To perform this role effectively, IT infrastructure managers require a diverse skill set with extensive experience in system, network and storage management. A background in cloud computing, cyber security, compliance and the ability to predict emerging IT trends is also beneficial, together with a degree in Computer Science, Information Systems, Project Management or a related field.
