What is IT infrastructure?

IT infrastructure is the combination of hardware, software, networks, cloud resources, and people that support and maintain an organization's technology operations. It includes physical components like computers and servers, software applications for productivity and collaboration, secure networks, cloud platforms for flexible data access, and the teams who manage and support these resources.

A strong IT infrastructure helps businesses:

• Securely store and manage data
• Improve employee collaboration and productivity
• Enhance customer experience and service delivery
• Quickly scale operations across global teams

In short, IT infrastructure forms the digital backbone of modern organizations, ensuring seamless operations and reliable growth.

Core components of IT infrastructure

Your business’s IT infrastructure has five key parts. Getting each right sets your global team up to work better, collaborate more easily, and deliver results without friction:

1. Hardware

Hardware includes all the physical tech you rely on daily—laptops, servers, routers, printers, and storage devices. This equipment forms the backbone that supports everything else.

The key to good hardware management? Choose reliable devices suited to your team's actual needs—don’t overspend on complexity you won’t use. Your hardware should also scale easily, so as your business grows, your tech can keep up without constantly needing costly upgrades.

Hardware is the physical equipment your teams use daily:

• Computers and laptops for daily operations and remote collaboration.
• Servers and data storage devices to securely store business-critical information.
• Network equipment (routers, switches) ensures reliable connectivity.
• Peripheral devices like printers or scanners, essential for everyday workflows.

2. Software

Software refers to the programs and apps that keep your business running smoothly.Typically, this includes:

• Operating systems (Windows, macOS) for smooth device performance.
• Collaboration platforms (Slack, Zoom, Microsoft Teams) to help teams work efficiently.
• Productivity and business software (CRM, ERP, accounting systems, Deel’s HR platform) automating repetitive tasks like onboarding or payroll.
• Security software (antivirus, encryption tools) to safeguard your business and customer data.

Good software automates repetitive, low-value tasks like payroll or onboarding paperwork, freeing your team to focus on more strategic work. Choosing user-friendly, integrated software solutions significantly reduces workflow bottlenecks and boosts team productivity—no matter where your employees work.

3. Networks

Networks allow your software and hardware to communicate smoothly, whether your teams sit in one office or span across multiple continents. Networks include:

• Local area networks (LAN) connecting devices within an office.
• Wide-area networks (WAN) or VPNs, securely linking remote offices.
• Wireless networks (Wi-Fi) allowing flexibility for mobile or remote teams.
• Security components like firewalls, intrusion detection (IDS), and data loss prevention (DLP) solutions protecting against cyber threats.

Having a reliable, secure network ensures smooth internal collaboration and communication. It keeps sensitive data protected from cybersecurity threats like phishing or ransomware, which are increasingly common with globally dispersed teams.

4. Cloud services

Cloud services offer storage, software, and computing power delivered through the internet. Instead of hosting everything onsite, you pay only for what you use, scaling resources quickly as your needs evolve. Common cloud models include:

• Software-as-a-Service (SaaS)—apps hosted online (like Deel’s HR tools), accessible from anywhere.
• Infrastructure-as-a-Service (IaaS)—servers and storage hosted remotely, easily scalable as your company grows.
• Platform-as-a-Service (PaaS)—fully managed environments for developers, reducing IT management overhead.
• Function-as-a-Service (FaaS)—serverless computing letting you quickly deploy and run applications without managing underlying infrastructure.

5. IT support teams

Your IT support team is there to make sure your technology actually helps rather than hinders your employees. They handle everything from onboarding new hires and troubleshooting tech issues to maintaining compliance and keeping software up-to-date.

Investing in the right people to manage your IT systems makes all the difference. Prompt, knowledgeable support keeps downtime to a minimum and lets your global workforce feel well-supported, reducing frustration and increasing job satisfaction.

IT support teams typically manage tasks like:

• Employee onboarding and offboarding, ensuring new hires have everything they need on day one and sensitive access is revoked promptly after departures.
• Device lifecycle management, from procurement to secure disposal.
• Security monitoring and compliance, proactively addressing threats and regulatory demands.
• Technical support and troubleshooting, minimizing downtime and frustration for your workforce.

6 steps to build a scalable IT infrastructure

Below are 6 steps that you can follow if you want to build a scalable IT infrastructure for your global team:

1. Assess your current system

Assessing your IT infrastructure components helps you identify vulnerabilities in your system that bad actors can exploit. For example, evaluating your IT infrastructure for compliance with industry standards—such as GDPR, PCI-DSS, and HIPAA—helps you mitigate potential compliance issues.

IT infrastructure assessment helps you determine whether your system can navigate surges or declines in traffic. Similarly, it helps mitigate downtime in your operations, utilize resources efficiently, and identify areas requiring improvements.

As a global team, assessing your IT infrastructure can be capital-intensive and requires a lot of manpower. It involves documenting and evaluating your compliance, security systems, and IT components in different regions for optimal business performance.

2. Implement security measures

Security breaches can lead to data loss, downtime, and disrupt business continuity. This has made a lot of businesses lose money from damaged reputations, hefty fines, and lawsuits. According to Cybersecurity Ventures, the cost of global cybercrime is expected to be $105 trillion annually by 2025.

When you implement solid security measures, your system, data, and IT assets are protected from bad actors. Additionally, you should have measures in place to detect and respond to cyber threats, from phishing attempts to IoT botnets and ransomware attacks.

One way to ensure your security system and sensitive data are secured is to comply with security and privacy standards. Standards such as GDPR, HIPAA, ISO 27001, and PCI-DSS dictate how data can be collected, transferred, and protected.

You can also add an extra layer to your security system by investing in cybersecurity tools, such as firewalls, data encryption, email security, and Backup and Disaster Recovery (BDR). A firewall system, for example, serves as the first line of defense in your security system. It filters your network parameters by blocking out unauthorized users and granting access to legitimate traffic, from co-workers and customers.

Likewise, integrating data encryption solutions into your security system encrypts your data across devices, making it confidential to unauthorized user parties.

As an HR or IT manager overseeing a global team, juggling multiple standards can be a handful. However, Deel has global coverage which ensures international compliance. Our security framework is also packed with data encryption, GDPR compliance, SSL/HTTPS shields, and periodic tests and updates.

3. Centralized IT management system

One of the main challenges businesses encounter with IT infrastructure is data silo. When the same data is stored in different places, it creates redundancy and barriers to efficient team communication and collaboration. This makes it hard for IT and HR managers to keep track of stored data as your business needs grow.

However, a centralized IT management system ensures all your data are stored in one place. This enhances employee communication and collaboration across different departments of your organization. Not only that, it offers real-time visibility into the performance of your IT assets.

With an IT management system like Deel IT, you can eliminate the complexity of managing IT infrastructure in a distributed team. Deel IT’s dashboard offers a unified platform for easily tracking remote devices, software updates, and compliance status. This tool allows HR and IT teams to collaborate seamlessly, reducing device management misunderstandings.

Deel’s Zero-touch deployment enables you to automate setting up devices in a work environment and managing them remotely in a centralized platform. This feature also allows you to automate upgrades for your enrolled devices, which improves your security system and increases fast loading time.

4. Adopt cloud-based solutions

Building a scalable IT infrastructure ensures your system and processes can easily accommodate increased workloads without compromising your business operation's quality, reliability, or security. It also helps you utilize your resources efficiently.

As an organization with a global team, adopting a cloud-based solution allows your employees to easily access data on the cloud anywhere with an internet connection. It also provides flexibility that lets you scale up your storage as your business needs grow.

A fitting example of a cloud-based is Deel’s secure HR document management, which gives you oversight of all files for easy access. It also has a centralized storage feature that lets you monitor who views, edits, and downloads files.

5. Automate your business processes

Automating your business processes with the right tool can improve the overall operational efficiency of your organization.

For example, automating repetitive tasks such as onboarding and offboarding, payroll processing, and password resets can help boost your team's performance.

By automating repetitive tasks, your team can also focus on more important things like employee development opportunities for organizational growth.

6. Make sure your system integrates

An IT integration ensures IT infrastructure works together by ensuring data flows smoothly between departments to support organization efficiency.

When your data and workflow are unified with IT integration, they enhance your decision-making and eliminate silos. This results in improved communication, and streamline your business operation.

Deel integrates seamlessly with various HR and IT software to save employee time and boost efficiency.

Integrating Deel with other IT stacks can help you automate repetitive tasks from creating contracts to syncing timesheets for payouts.

Why is scalable IT infrastructure important for modern companies?

A scalable infrastructure quickly adjusts to business growth by automating repetitive tasks. It enhances operational efficiency and easily adapts to changes in your demands, which lets you optimize resources and workforce efficiently.

Leveraging cloud-based platforms also makes it easier for different departments in your organization to collaborate on projects.

Without a scalable IT infrastructure, your business would have difficulty keeping up with increased customer traffic. During downtimes, customers would have to wait in line before their orders were fulfilled, which would lead to a poor customer experience.

Additionally, businesses without flexible and adaptable infrastructure struggle to navigate increased demand during peak seasons such as holidays. On the other hand, implementing a scalable strategy helps you utilize resources efficiently by ensuring you avoid over-provision during peak seasons and under-provision during off-seasons.

What makes building scalable IT infrastructure so difficult?

Below are some likely challenges you might run into when building a scalable IT infrastructure:

Complex device logistic

To ensure efficient device lifecycle management, there are steps you must follow: procurement, provisioning, maintenance and support, reconfiguration, and delivery. Each step has its challenges, leading to late delivery, bottlenecks, and non-compliance risks.

For example, when one of your managerial staff sends out a work laptop for IT maintenance—and it takes too long to retrieve it—such delay can potentially disrupt your business operation.

Similarly, keeping track of all devices—such as maintaining device lifecycle management and providing round-the-clock IT support—can be difficult to achieve when you have a dispersed workforce.

Compliance risks

Each country has its own set of laws and regulatory standards. This makes it challenging for organizations with a global workforce to navigate varied regulatory requirements across multiple countries.

Similarly, you might also have to deal with security standards that are contradictory. This means the data privacy standards and environmental requirements for decommissioning devices from different regulatory bodies could be different.

For instance, General Data Protection Regulations (GDPR) require businesses to comply with SCCs requirements for cross-border data transfer. In contrast, the California Consumer Privacy Act (CCPA) doesn’t have such restrictions.

IT system fragmentation

Integrating IT systems allows real-time data-sharing and analysis of performance. It also streamlines collaboration and communication among the distributed workforce.

In a fragmented IT environment, data is siloed in different systems, resulting in inaccuracies and inconsistencies. This can hinder strategic planning and data-driven decision-making. Additionally, a fragmented IT system requires higher maintenance costs and additional IT staff to consolidate siloed data in one place.

Your HR and IT team might struggle to collaborate on tasks, such as onboarding, offboarding devices in remote destinations , support, device management, and compliance when you fail to invest in tools that don’t facilitate such integration.

Limited IT visibility

Visibility gives you real-time insight into the performance of your IT infrastructure components. Relying on a system that doesn’t give full visibility makes it difficult to monitor and manage devices remotely. This makes it identify security risks that could disrupt your operations.

With full visibility, your IT and HR team can keep track of the system performance, network traffic, and security alerts in real-time. As an organization with a global team, your IT assets will be managed from a dashboard. Additionally, you will be able to identify potential technical problems and provide immediate support before they disrupt your operations.
