IT Architecture · Solution Design

We build IT infrastructure
tailored to your business

We design secure and efficient IT infrastructure based on analysis of real needs — not what's most expensive or most popular. Technically and cost-optimal solutions, without unnecessary overhead.

Service scope

What does IT solution design involve?

From requirements analysis to complete technical documentation and procurement support. We design infrastructure that works — not one that looks good on paper.

Hardware and system infrastructure architecture

We design IT infrastructure taking into account real needs and business goals. We analyze possible options and develop architecture meeting functional requirements at the network, server, storage, and security level.

Solution selection without overhead

We recommend what you actually need — not what brings us the highest margin. If mid-range meets the requirements, we don't propose enterprise. This approach actually optimizes infrastructure investment costs.

Constraints analysis and optimization

Every company has specific constraints — budget, existing infrastructure, regulations, human resources. We analyze these constraints and select the optimal solution that allows tasks to be performed efficiently in real conditions.

Technical documentation and HLD/LLD

The project ends with complete documentation — High Level Design and Low Level Design, network diagrams, device specifications, security configuration. Documentation sufficient for self-deployment or assigning it to any contractor.

Procurement support

We help verify vendor offers, negotiate purchase terms, and evaluate alternative proposals. We act on your side — independent of any vendor — so you get what you need at a reasonable price.

Security design as an integral part

We design security together with infrastructure — not as an afterthought. Network segmentation, access control, data protection, and business continuity are part of every infrastructure design from the very beginning.

Our approach

We don't sell architecture for its own sake

A typical integrator proposes what brings the highest margin. We propose what best solves your problem — even if it's a simpler and cheaper solution.

Typical integrator approach

"Oversized" architecture

Proposal of the top-tier, most expensive solution — regardless of real needs

Enterprise-grade hardware for a company that needs mid-range
Licenses and modules that no one will ever use
Complex architecture requiring expensive maintenance
Proposal of specific manufacturers because we have partnerships with them
A design that looks impressive but is hard to deploy and manage
Result: you overpay for infrastructure and pay a lot for its maintenance.
VOL System approach

Architecture tailored to needs

Recommendation based on requirements analysis, not on margins and partnerships

Solution selection for real requirements — not "just in case" requirements
Justification for every recommendation — you know why, not just what
Design considering the administrative capabilities of your IT team
Vendor independence — we recommend what's best for you
Architecture that can be maintained without expensive external specialists
Result: you invest as much as you should — no more. Infrastructure serves long.

Design areas

What do we design?

Full range of IT infrastructure — from network perimeter to cloud environments. Security is an integral part of every design, not an option.

LAN / WAN / WLAN Networks

Corporate network architecture — from logical to physical design. Segmentation, redundancy, performance, and security as the foundation of the design.
LAN / WLAN SD-WAN SSE / SASE VPN QoS

Security and perimeter protection

Security architecture design — firewalls, segmentation, access control, protection against external and internal threats.
NGFW NAC IPS/IDS Zero Trust DMZ
Cybersecurity →

Endpoint protection

Design of policies and endpoint protection architecture — laptops, desktops, mobile devices, remote work environments.
EDR / XDR MDM Policies Patch mgmt
Endpoint protection →

Datacenter and server infrastructure

Design of compute and storage infrastructure — local, hybrid, or cloud. High availability, virtualization, and scalability.
Servers Virtualization Storage HA / Klastry HCI

How we design

Four stages from requirements to finished design

A simple process without unnecessary bureaucracy. At every stage you know what's being created and why.

1

Requirements gathering and environment analysis

We talk with your IT team (and management if needed) about business and technical requirements, constraints, existing infrastructure, and development plans. We invest time in understanding the context — so the design responds to real needs, not our assumptions.

2

Option analysis and technology selection

We evaluate available technology options — hardware, software, and cloud — for fit with requirements, TCO costs, administrative capabilities, and long-term support. We recommend with justification, not from a corporate list of preferred vendors.

3

Architecture design (HLD / LLD)

We develop a High Level Design describing the overall architecture and logic of the solution, and a Low Level Design with configuration details, network diagrams, and device specifications. The documentation is sufficient for self-deployment or handing over to a contractor.

4

Procurement and deployment support

We help verify offers, negotiate with vendors, and evaluate alternative proposals. Optionally we take over project deployment with our team — or support your in-house IT team during execution.

For whom

Who benefits from IT solution design?

Infrastructure design is needed whenever you face an important technology decision — and want to make it consciously, not reactively.

IT Director / Head of IT

You need a technical design that meets security, performance, and scalability requirements — and that you'll be able to justify to management. We deliver architecture with justification for every design decision.

CFO (Chief Financial Officer)

Investment in IT infrastructure is often one of the larger expenses. An independent expert's design gives confidence that the proposed budget is justified — and that you're not overpaying for a solution that's not fit for purpose.

Company expanding infrastructure

You're opening a new branch, scaling the network, deploying an ERP system, or moving to the cloud. Each of these changes requires a thought-through design — so the new infrastructure doesn't fail to integrate with the old.

Company after a security audit

The audit identified gaps — now you need a technical design that addresses them. We design security solutions tailored to audit results, budget requirements, and deployment capabilities.

Independent technology consulting

A good infrastructure design costs many times less than a bad purchase.

Errors in IT architecture come to light during deployment or a few years later — always at the worst possible moment. Better to spend time on the design than on redesign.

FAQ

IT solution design questions

IT solution design includes: business and technical requirements analysis, selection of optimal technologies and products, architecture development (HLD and LLD), preparation of technical documentation and diagrams, and procurement and deployment support. The result is a ready-to-execute infrastructure design tailored to needs and budget — with justification for every key design decision.
VOL System is an independent advisor — we design the solution best fitted to client needs, not necessarily the one that brings us the highest margin. We can also help with procurement: verifying offers, negotiating with vendors, and evaluating alternatives. Deployment is handled by our team or we can hand the design over to the client's in-house IT team for execution.
Time depends on complexity and scope. A simple network architecture for a 50-person company is typically 1–2 weeks from gathering requirements to finished design. Complex datacenter projects or production environment migrations can take 4–8 weeks. In the first conversation we can give a realistic schedule for a specific case.
We design the full range of IT infrastructure: LAN/WAN/WLAN networks, security (NGFW, EDR, NAC, IAM), datacenter (servers, storage, virtualization, HA), cloud and hybrid environments, backup and business continuity systems. We treat security as an integral element of every design — not as an optional add-on.
Cost-optimal means we select a solution that meets requirements — without unnecessary overhead. We don't propose enterprise-grade hardware to a company that needs mid-range. We don't sell the most expensive products if cheaper alternatives meet technical and business requirements. Our recommendation always includes justification why a specific solution is appropriate — not just what we recommend.
