Infrastructure Services

Is the infrastructure your business runs on current, supported and recoverable?

One team for the servers, hypervisors, networks, firewalls, storage and backup your business runs on, across vendors. We design, deploy, migrate and support those platforms, starting with a fixed-fee assessment.

Our approach

One team for the servers, hypervisors, networks, firewalls, storage and backup your business runs on, across vendors. Kalosys designs, deploys, migrates and supports those platforms, starting with a fixed-fee assessment so every decision is backed by evidence.

Start with your question

Which of these sounds like you?

Your starting point

Server Operating Systems

Most estates mix Windows Server with several Linux distributions, and a few systems are usually past end of support.

You receive

Inventory and lifecycle findings · A recommendation

Timing and scope

Start with a fixed-fee assessment of the platforms in scope.

Six technology areas

The platforms your business runs on

55 platforms across six areas. Each area starts with a fixed-fee assessment.

Support levelsWhat Standard and Conditional mean

Standard

Delivered as part of our standard engagements, with established designs, runbooks and experienced engineers.

Conditional

Supported, subject to a scoping review of version, licensing and vendor support status, confirmed before we commit to the work.
What we hearWhy these decisions come up now

Platforms age out on someone else's schedule

End-of-support dates for operating systems, switches, firewalls and arrays set the timeline.

Licensing is changing

Virtualization licensing changes are pushing many organizations to rethink their hypervisor, usually in phases.

Estates sprawl across vendors

Years of site-by-site growth leave mixed platforms and missing documentation.

Recovery is now a business question

Ransomware turns untested recovery into a business risk.

How we engage

Assess, Build, and Support if you want it

Each step stands on its own. Start with the assessment: it is low risk and produces the evidence needed to scope the work.

  1. 01

    Assess

    Fixed fee. Inventory, health and lifecycle review of the platforms in scope, ending with findings, a recommendation and a fixed-scope proposal. The recommended first step.

  2. 02

    Build

    Fixed scope with milestones. Design, deploy, upgrade or migrate, then validate and hand over with documentation and runbooks.

  3. 03

    Support (optional)

    If you want it: health checks, patching and lifecycle planning, with hardware, procurement and maintenance where needed. Each step stands on its own.

Our commitmentsWhy Kalosys
  • Broad platform coverage: 55 platforms across six technology areas, most delivered as Standard with established designs, runbooks and experienced engineers.
  • Across vendors: we compare options rather than start from one product.
  • Evidence before commitment: every platform decision is backed by inventory, cost and risk evidence.
  • Fixed fees, clear scope: assessments are fixed fee, and builds are fixed scope with milestones.
  • Resilience built in: backup, recovery and security are designed in, with our Business Resilience practice alongside.
  • One place for the work: hardware, procurement and ongoing maintenance as part of the engagement where needed.
Who we work withWhat each leader gets

CIO / CTO

One team across vendors, evidence-backed decisions, fixed fee and fixed scope, and a plan for each end-of-life system.

VP / director of infrastructure

Inventory and lifecycle evidence, an options and cost comparison, and migration without disruption.

IT operations and platform teams

Standard builds and baselines, documentation and runbooks you keep, and less routine work.

CISO / network and security teams

Rule-base clean-up, high availability, immutable backups and tested recovery, with audit and insurance evidence.

Business continuity and IT operations leads

Coverage and recovery-target review, scheduled recovery tests and DR runbooks.

Also from Kalosys

Related practices

Microsoft and AWS platforms have their own practices. Network and storage moves often sit inside a data center migration, and the wider continuity program sits with Business Resilience.
