Setting up an IT infrastructure: The most important components and requirements

The most important thing in brief:

The digital performance of a company depends on IT infrastructure. A professional IT infrastructure construction Forms the basis for safety, efficiency and scalability in everyday work. But how can you get a Build IT infrastructureWhich requirements must be considered, and which components play a central role?

In this article, you will get a comprehensive overview of the structured structure of an IT infrastructure, learn the most important phases and learn how a software-based solution such as Docusnap helps to gain transparency and control over your IT landscape.

Setting up an IT infrastructure: Why the structure is essential

In times of hybrid working models, growing security requirements and increasing IT complexity, it is crucial for companies to professionally set up their IT infrastructure. This is the only way to reliably protect data, make processes efficient and meet future requirements flexibly.

However, many companies are facing challenges:

• Lack of overview of existing systems
• No documented dependencies
• Lack of scalability as you grow
• Unclear responsibilities in IT operations

This is where Docusnap comes in: The software supports graphical presentation of the IT infrastructure, at Current situation analysis and with continuous documentation — without the use of additional agents.

The main components — How can the IT infrastructure be set up?

A complete IT infrastructure Usually consists of the following basic components:

1. Hardware components

• Servers (physical or virtual)
• Clients (PCs, laptops, thin clients)
• Network components (routers, switches, firewalls)
• Storage Systems (NAS, SAN)

2nd Software components

• Operating systems (Windows Server, Linux)
• Application software (CRM, ERP, mail server)
• Virtualization platforms (VMware, Hyper-V)

3rd Network infrastructure

• LAN/WAN-Structures
• VPN accesses
• WLAN architecture

4th Security Infrastructure

• Firewall Systems
• Antivirus & Endpoint Protection
• Backup and recovery solutions

5th Cloud & hybrid components

• Use of Public/private clouds
• Interfaces between on-premises and cloud

The best way to get a complete overview of all components is through automated recording and visualization. Docusnap offers exactly these features — Up-to-date, centralized and clear. Agentless inventory allows all relevant hardware and software components as well as network structures to be efficiently recorded — regardless of whether they are servers, workstations, virtual machines, switches, or user rights.

Docusnap automatically creates from this graphical representations Such as network plans, Active Directory structures, or server diagrams that make IT dependencies and relationships visible. In addition, the software generates comprehensive Reports and Analytics, which can be decisive in license management, security reviews or audits, for example.

It doesn't matter What type of IT infrastructure Used in your company: Basically, there are two main forms — the local IT infrastructure And the Cloud Infrastructure.

The five phases of IT infrastructure development

The Establishing an IT infrastructure Ideally takes place in five clearly defined phases:

1. Needs analysis and goal definition

• What are the business requirements?
• Which systems are required?
• Which user groups are accessing when and how?

👉 Support is provided by our Current analysis of the IT infrastructure.

2nd Planning and Architectural Design

• Selection of suitable hardware and software
• Set network topology
• Consider safety requirements

3rd implementation

• Rollout of infrastructure components
• Setting up user and rights structures
• Integration into Existing Systems

4th Documentation and visualization

• Recording of all components in a central platform
• Automated Network Plans and Eligibility Overviews
• Regular updating of IT documentation

5th Operation and optimization

• Monitoring & maintenance
• License and patch management
• Development and scaling

Docusnap supports you in all phases — but especially when moving from planning to operational phase, where transparency, control and compliance are important.

IT infrastructure requirements at a glance

A professional IT infrastructure construction Must meet numerous requirements:

• Disponibilité: Systems must be functional at all times.
• Safety: Protection against unauthorized access and data loss.
• scalability: The infrastructure must be able to grow with you.
• Compliance: Compliance with legal and internal guidelines.
• Transparency: Complete documentation and traceability.

This is the major advantage of a solution like Docusnap, which not only offers inventory, but also automated reports, license management and authorization analyses — always with an eye on the IT infrastructure requirements of IT departments.

Practical example: Setting up an IT infrastructure in a medium-sized company

A medium-sized company with 120 employees was faced with the challenge of reorganizing its established IT infrastructure. The requirements were clear: centralized user and rights management, introduction of home office structures and secure backup systems.

With the help of Docusnap, a Complete as-is analysis , on the basis of which new server structures, firewalls and VPN accesses were introduced. Thanks to the graphical visualization, the project manager was able to keep an eye on all dependencies at all times — and complete the project on time and in a documented manner.

Conclusion: Building a solid IT infrastructure is not a coincidence — it's planning

The Building an IT infrastructure Requires strategic planning, precise implementation and continuous maintenance. Only those who understand and document their IT landscape can work efficiently, securely and compliantly in the long term.

With Docusnap, you have a reliable partner at your side who will help you with the entire IT infrastructure construction supported — from initial analysis to ongoing operation.
