Virtual Desktop Infrastructure Services
Desktop virtualization planned, built, and operated to hold up under real conditions
TRUSTED BY
Virtual Desktop Infrastructure Services
Calance designs, deploys, migrates, and operates virtual desktop environments for organizations managing a workforce spread across offices, homes, client sites, and personal devices. Endpoint fleets drift from the standard build, patch windows slip, business data accumulates on machines outside direct IT visibility, and support teams spend a disproportionate share of their week rebuilding devices rather than improving services.
Virtual Desktop Infrastructure addresses those pressures by relocating the desktop operating system, the user profile, and business applications into centrally managed infrastructure, then streaming the session to whatever device the user is holding. Organizations working with Calance gain auditable access, predictable logon performance, application compatibility verified before users encounter it, and a consumption model finance can plan against.

Advantages of Virtual Desktop Infrastructure
Reduced endpoint exposure
Business data stays in managed infrastructure rather than scattered across laptops, lowering the consequence of a lost or stolen device.
Faster onboarding and cleaner offboarding
Access is granted and revoked through identity rather than hardware procurement, which matters most for contractors, seasonal staff, and acquisitions.
Consistent application delivery
Applications are published from managed images, removing the version drift that accumulates across a physical fleet.
Continuity during disruption
Users reconnect from another approved device with the session intact, reducing dependence on any single piece of endpoint hardware.
Predictable support effort
Centralized image and patch management replaces device-by-device fixes, freeing help desk capacity for higher-value work.
Decoupled hardware refresh
Compute demand sits in the backend, so endpoint replacement cycles stop being driven by application requirements on the local device.
Virtual Desktop Infrastructure Models
Two decisions shape cost and operational effort more than any other: where the environment runs and how desktops are assigned to users.
How Calance Delivers Virtual Desktop Infrastructure -
Migration sequencing determines how disruptive a transition feels to the business. Moving a full population in one step concentrates risk, so Calance advances through defined stages with clear exit criteria between them.
Assessment and Discovery
- Document personas, concurrency patterns, and full application inventory
- Record network conditions and confirm licensing entitlement well in advance
- Establish which specific users and roles genuinely suit virtual desktops
Architecture and Design
- Agree the deployment model, host pool structure, and assignment approach
- Set session and access policy alongside our cybersecurity services team
- Define profile storage, image standards, and monitoring approach early
Foundation Build
- Establish identity integration, network paths, storage, and management tooling
- Validate the entire infrastructure before any session host gets deployed
- Coordinate closely with your wider IT infrastructure and operations estate
Image Build and Packaging
- Build, harden, and version golden images against the target session model
- Package and thoroughly test business applications before real users arrive
- Document exceptions carefully and agree a clear remediation path for each
Pilot and User Acceptance
- Run real work with a group spanning roles, locations, and connection types
- Collect feedback on sizing, policy, and image behavior under realistic use
- Adjust the full environment carefully before wider release, not just after
Wave Migration and Handover
- Move users in scheduled groups with clear onboarding guidance provided
- Retain a rollback path, supported closely through our IT help desk services
- Transfer monitoring thresholds and runbooks fully into stable steady state
Virtual Desktop Infrastructure Products
Platform selection follows from the estate, not the other way round. Calance remains vendor-neutral during assessment, so the recommendation reflects where your applications, identity, and data already sit.
Licensing entitlement differs meaningfully across these platforms and affects total cost more than most sizing decisions, which is why the entitlement position is verified before any architecture is proposed. Where the estate is Microsoft-centered, our Azure Virtual Desktop infrastructure services cover host pool design and ongoing operation in more depth.
Industries we serve
Healthcare and Genomics
Clinical staff move between units, facilities, and shifts throughout a single day. Virtual desktops keep the same secure session available at every workstation while keeping patient data off local devices.
Legal Services
Attorneys and staff work across offices, courtrooms, and client sites, often on devices IT doesn't fully control. Centralizing the desktop keeps case files and communications inside managed infrastructure.
Financial Services and FinTech
Contractors and distributed teams need access that can be granted and revoked quickly, tying entitlement to identity and supporting the audit trail compliance expects.
Construction and Engineering
Project teams split time between the office, job sites, and partner locations, often on personal or shared devices, and virtual desktops keep access consistent without extending the endpoint footprint IT has to secure.
Manufacturing
Shift-based and shared-workstation environments suit non-persistent desktop pools well, letting operators sign in from any approved terminal without carrying local data between shifts.
Sizing by User Workload Profile-done
Concurrency alone does not size an environment. A hundred concurrent call centre users and a hundred concurrent CAD users place entirely different demands on compute, storage, and network, which is why Calance profiles the user population by workload class before any capacity decision is made.
Why Calance for Virtual Desktop Infrastructure Services - done
Desktop virtualization sits at the intersection of infrastructure, identity, Microsoft platforms, and security. Few providers operate credibly across all four. Calance has delivered in each of those areas for more than two decades, which is what a VDI program actually requires.
Four Practices, One Team
Infrastructure, Microsoft, cybersecurity, and help desk capabilities sit under one accountable partner, so identity, network, image, and support decisions are made together rather than negotiated across separate vendors.
25+ Years of Production Environments
Founded in 2003 and part of the DTS Group, Calance runs infrastructure for enterprises in healthcare, automotive, manufacturing, and financial services, with a 90% client retention rate behind that record.
Vendor-Neutral by Design
Calance holds partnerships across Microsoft, VMware, Citrix, AWS, and Cisco without reselling any single platform, so the platform recommendation reflects your estate rather than a licensing arrangement.
Onshore Leadership, 24/7 Coverage
US-based architects own scope and design decisions while teams across the United States, Canada, and India provide follow-the-sun monitoring, so an environment is supported past business hours from day one.
Frequently Asked Questions
Assessment and design usually run four to eight weeks depending on estate complexity. Migration then proceeds in waves, so total duration reflects user count and application exceptions rather than a fixed project length.
Standard office work generally functions on modest bandwidth, but latency matters more than raw speed. Graphics workloads and video calls need considerably more headroom, which is why connection quality gets tested at actual user locations.
Virtual desktops require an active connection, since the session runs in the datacentre rather than on the device. Roles with frequent offline requirements are usually better served by managed physical devices.
Non-persistent pools allow hosts to be updated in batches while users work on remaining capacity. Persistent desktops require scheduled windows, communicated in advance, with drain modes preventing new sessions on hosts being patched.
Yes. Most platforms provide native clients across these operating systems, plus browser-based access. Peripheral support and screen handling differ by client, so the experience per device type is validated during pilot.
Existing hardware can usually be repurposed, which often extends its useful life considerably. Whether to move to thin clients depends on management overhead, security posture, and where each device sits in its replacement cycle.
Density depends entirely on workload profile, host sizing, and the application mix. Task workers achieve high density on shared hosts, while graphics users may need dedicated resources, so figures come from measurement rather than estimates.
Handover covers image management, provisioning, monitoring thresholds, and escalation procedures, with runbooks documented for the team taking ownership. Depth is scoped to whether your team retains administration or transfers it to Calance.
Departmental deployments are common and often sensible. Starting with a group whose workload clearly suits virtualization builds operational history before wider rollout, and some organizations never extend beyond those roles.
Session hosts require endpoint protection like any other Windows machine, configured for virtual environments to avoid scanning storms across concurrent sessions. Exclusions for profile containers are set during image hardening.
Sessions typically remain active on the host for a configured period, allowing reconnection with work intact. Disconnect and logoff timers are set during design to balance user convenience against capacity consumption.
Multi-monitor configurations are supported across major platforms, though each additional display increases bandwidth consumption and host resource use. Monitor requirements are captured during assessment because they affect both sizing and network planning.
Pilots are strongly recommended. Real users across different roles, locations, and connection types surface sizing and policy issues that no test environment reproduces, and correcting those before wider release avoids disruptive rework.
Some vendors license per device, per user, or per concurrent session, and virtualized delivery can change which model applies. Application licensing is reviewed during inventory, since assumptions here frequently produce unexpected costs.
Effort depends on the operating model agreed at handover. Organizations retaining full administration need dedicated capacity for image and capacity management, while co-managed arrangements transfer that workload while keeping architecture ownership internal.
