IT infrastructure design and deployment

IT infrastructure design starts with your business needs, existing environment and planned growth. We plan server, network, storage and access architecture, migration steps and handover documentation. The solution is based on actual workloads, risks and expected growth.Discuss an infrastructure projectExplore this service

SERVICE ASSESSMENT

Infrastructure project readiness diagnostic

Assess requirements, architecture, deployment and handover systematically. After providing your email, see an answer-based overview, priorities and actions; a PDF will be sent to that address. This is not an independent audit conclusion.

AT A GLANCE

A clear starting point

Who it is for

Businesses building, expanding or redesigning infrastructure around their operational, data and access requirements.

What we need to start

Provide current environment details, application requirements, expected growth and the downtime your operations can tolerate.

What you receive

Receive deployed infrastructure, architecture documentation, acceptance-test results and clearly assigned maintenance responsibilities.

WHO IT IS FOR

IT infrastructure design: what does your business need?

IT infrastructure design plans the future technical environment and responsibilities before equipment is purchased or deployed. A deployment project should end with testing, documentation and a clear handover to support, as well as working equipment.

The project starts with what the business needs to do: which applications employees use, where they connect from, which data matters most and which outages directly stop operations. We assess locations, workstation numbers, expected growth and existing equipment. This becomes a set of architectural requirements, rather than simply a shopping list for new hardware.

We ask for the current environment diagram where available, an equipment and licence inventory, and known problems. Acceptable downtime, access needs and budget limits are discussed separately. Where essential information is missing, gathering it becomes the first task: an architecture based on unverified assumptions would be difficult to justify.

SCOPE

What infrastructure do we design?

The architecture connects networking, computing resources, storage and administrative access. Its diagram should show more than devices: data paths, service dependencies and points whose failure would affect several systems also matter. Scope follows the client’s needs; replacing every part of the environment at once is not a prerequisite for a useful project.

  • Deployment ends with an agreed handover. Everyday support is arranged separately.

What infrastructure do we design?

Network and VPN

The network plan follows workstation locations, device groups and the connections required between sites. Remote access, its users and administrative permissions are documented separately. A VPN must fit the access scenario; creating a tunnel does not replace account and permission management.

Servers and virtualisation

Server and virtualisation planning is based on application workloads, compatibility and recovery needs. Spare capacity is justified by a growth scenario, rather than a promise that the equipment will handle any future load. We also identify dependencies that replacing one server would not resolve.

Storage and backups

Storage planning considers data volume, growth, access-performance needs and the impact of failure. Backup locations and recovery paths are planned separately from everyday storage. Backup scope must identify the protected assets and the checks that will be used to assess recoverability.

  4. Data storageOperational data and the permissions governing access.
  5. Separate backupsPlanned restore points and a route to recover the system.

A simplified relationship between components, not a client network diagram. Included components and access boundaries are established during design.

How are equipment and architecture selected?

We compare what can reasonably be retained with what should be replaced because of support, capacity or risk. Where several options are suitable, we explain their differences: initial investment, licensing and maintenance needs, expansion options and recovery complexity. The lowest purchase price does not necessarily mean the least operational effort.

Equipment and platform choices are tied to testable requirements and compatibility. Before an order is placed, we distinguish deployment work from supplier hardware, paid licences and subsequent maintenance. The client should understand both the consequences of a choice and the assumptions that constrain it.

Veeam backup and recovery capabilities are considered as one part of the infrastructure design; their use depends on the protected systems and licences.

How do we plan changes around business operations?

The migration plan defines the sequence, data-transfer method, cutover point and responsible contacts. With the client, we choose a suitable window, staff communication process and the functions that must be checked before the environment returns to use. Where practical, a limited pilot tests the migration of a selected asset first.

Before starting, we verify backups and the conditions for returning to the previous state. The plan identifies any step after which rollback would require additional data reconciliation. Expected downtime is assessed against application and infrastructure capabilities, with likely operational impact explained before approval.

How we work

Each stage defines the work, your input and the result to check.

01

Assessing requirements and the existing environment

We collect operational, data, access and growth requirements alongside the current environment records. The result is a requirements list with uncertainties that must be resolved before design.

02

Agreeing architecture and options

We prepare the architecture and explain differences between suitable options. The client selects a solution with visibility of its maintenance needs, risks and acceptance checks.

03

Planning equipment and licences

We define the equipment, licences and deployment work required. Compatibility and ownership are checked so purchasing decisions match the approved architecture.

04

Deployment and migration

Deployment and migration follow the agreed sequence and work window. We record changes, check intermediate results and apply the planned rollback conditions if checks fail.

05

Testing, documentation and handover

We run acceptance tests with the client representative and hand over the documentation. Open issues and ongoing maintenance responsibilities are recorded in the handover outcome.

What do you receive after deployment?

After deployment, we provide an updated architecture diagram, equipment and system inventory, addressing records and copies and descriptions of important configurations. Access information is transferred securely and kept separate from the general project report. The records identify where settings are stored, who owns each component and who handles licensing or warranty support.

Acceptance follows predefined tests: required connections, user access, application operation and any recovery checks included in scope. Results are recorded, with outstanding issues assigned an owner and a next action. Switching on a device is not, by itself, sufficient evidence that the whole project is complete.

How is the infrastructure maintained afterwards?

At project completion, the client needs to know who will maintain the infrastructure. We hand over the assets requiring monitoring, recurring maintenance needs and hardware or software support limitations. If an internal team or another provider takes responsibility, the documentation is reviewed with its designated contact.

Deployment and ongoing maintenance are separate scopes. Workstation support may need a managed IT plan, servers an administration plan, and backups explicitly scheduled checks. Ownership of these areas is recorded before the project closes so that components are not left without a responsible maintainer after handover.

Illustrative scenario: opening another business location

A business opens another location that needs access to a shared application and company documents. We first compare where the data resides, which applications must operate locally and what happens if connectivity is lost. Only then do we choose the network, remote-access and local-device approach.

Handover tests cover an employee login, the required application task and the separation of access rights. This is an illustrative design scenario, not a completed client project; the final equipment list would depend on the requirements collected.

FAQ

Frequently asked questions

Deployment is a project with a defined outcome: a new or upgraded environment is planned, prepared and handed over. Support is its ongoing maintenance afterwards. Both services can be coordinated, but their scopes differ.

Yes, if their condition, support status and capabilities suit the project. We first inventory the equipment and assess limitations. Reusing ageing equipment should not automatically be presented as safer or cheaper.

Network segmentation and VPN can form part of an infrastructure project. The solution depends on locations, equipment, user access needs and security requirements. Specific technologies are set out in the technical design.

Backup and recovery architecture can be planned within the project. Storage resources, licences, ongoing maintenance and recovery tests must be identified separately in the proposal.

That depends on the system and its ability to run in parallel. Where cutover requires downtime, it is planned and agreed in advance. A clear test and rollback plan is needed before migration.

The agreed technical documentation is handed over: architecture, equipment inventory, configuration information and test results. Secret credentials are transferred through a separate secure channel rather than included in a public project description.

The cost includes analysis, design, deployment, migration and planned third-party expenses. Equipment, licences, connectivity and long-term support should be itemised so the full investment is clear.

The environment can be handed over to the client’s IT team, or Dev4you.lt support can be agreed. Handover defines responsibilities, documentation and remaining risks. Post-project support must have separately defined terms.
