CIO / Head of IT

Unblock your cloud strategy without rewriting the business

When one legacy Windows application holds your entire datacentre exit hostage, WebStream delivers browser access with governance — so the program moves forward, not the rewrite debate.

Your Challenges

When the cloud program stalls on one application

Most CIOs aren't blocked by infrastructure — they're blocked by a single line-of-business app that can't be refactored on the timeline the board expects.

Cloud program stalled

ERP, accounting, or industry-specific Windows software remains on-prem while everything else has moved — making datacentre exit impossible to declare complete.

Rewrite too costly

Vendor quotes and internal estimates for replacement or re-platforming run into years and millions — with unacceptable business disruption risk.

Hybrid workforce friction

Remote and office staff need the same access to critical apps, but VPN and RDP create support load and security exceptions your team can't sustain.

Board pressure without a path

Cloud-first mandates and cost-reduction targets need a credible answer for the legacy app — not another "we're evaluating options" quarter.

How WebStream Helps

Move the program forward in weeks, not years

WebStream sits between the browser and your existing Windows application — no rewrite, no replacement project.

Unblock datacentre exit

Lift the blocking application to AWS with browser delivery — so the cloud program can close its last on-prem exception.

Browser access for every user

Staff open the same application from any location — no VPN client, no RDP configuration, no per-device installs.

Governance your security team can approve

Policy control over files, print, clipboard, and session activity — so cloud delivery passes review without blanket RDP exceptions.

Case Vignette

When one client blocked the entire exit

Illustrative scenario — composite anonymised example

“We had moved email, files, and most workloads to the cloud. One ERP client on Windows was the reason we still couldn't close the datacentre.”
Situation
A mid-market organisation with ~400 staff had completed most of its cloud migration. A legacy ERP/accounting Windows client — deeply integrated with payroll and reporting — was the last on-prem holdout. Replacement quotes exceeded budget; RDP was rejected by security.
Approach
IT ran a WebStream PoC on AWS with the existing application unchanged. Browser delivery was tested with finance and payroll teams over three days. Security reviewed file and print policies before wider rollout.
Result
The PoC completed in days, not months. The CIO had a board-ready path to datacentre exit without funding a multi-year rewrite — and hybrid staff accessed the app from browser without VPN tickets.
Typical Applications

Where CIOs deploy WebStream first

Accounting & Finance

Practice management, ledger, and compliance tools that run on Windows and can't be replaced without disrupting month-end close.

ERP

Industry ERP clients and thick-client modules that anchor operational workflows — too critical to refactor on a board timeline.

Government Admin

Legacy administrative systems with long procurement cycles — where cloud delivery must meet strict access and audit requirements.
