Real systems. Real risk.
Modernised without rewrites.

Each of these programmes started with a hard deadline, a complex estate and a question no one wanted to answer: who owns the legacy? Here is how Cloudhouse helped close them.

Guardian Banking · United States

A US state-chartered bank

From 70 servers to over 400 in 14 years, with regulators asking sharper questions every quarter. Configuration management had to mature, fast.

98%+
Compliance reported monthly to the board
100%
VMware ESXi compliance, sustained
4wks
Implementation, end to end

Without Guardian, two to four full-time staff would be managing configurations manually. Instead, the team focuses on Federal Reserve work and strategic compliance.

Alchemy Conglomerate · Singapore

Keppel Group

A greenfield AWS customer, a data centre exit, and a stack of Windows Server 2008 systems blocking the migration plan.

13
Servers packaged: web, app, SQL
$3M
ARR unlocked for AWS via EMP programme
100%
EOS servers decommissioned at cutover

Cloudhouse worked alongside Accenture to package every End-of-Support workload, removing the last technical blocker between Keppel's data centre and AWS.

Alchemy Utilities · United States

A major regional water authority

One of the largest public water utilities in the United States, serving 19 million people across six counties. Operational continuity is non-negotiable.

19M
People served by the network
6
Counties dependent on uptime
$489k
2026 renewal, multi-year footprint

A multi-year Alchemy footprint keeps essential operational technology compatible with modern Windows, without disrupting the systems that move water.

Alchemy Government · United Kingdom

UK Home Office

Border security, immigration and policing rely on systems that cannot be paused for a rewrite. Cloudhouse keeps them running on supported platforms.

5k+
Staff supported by the application estate

Of several long-standing UK government deployments
2026
Renewal completed, programme ongoing

Alongside the Ministry of Justice, DWP, Fife Council, North Tyneside Council and the IPO, the Home Office is part of a long-standing Cloudhouse public sector estate.

Foundry Gaming · United Kingdom

Team17 Wormnet

The matchmaking service behind the global Worms gaming franchise ran on a Debian VM with three tightly coupled services. The team needed to modernise onto AWS-native infrastructure without disrupting live multiplayer.

3
Services containerised: Web, IRCD, MariaDB
ECS
Fargate & AWS RDS, fully native
0
Source code access, zero downtime

Foundry analysed the Debian VM image, packaged the Web and IRCD services as containers on ECS Fargate, and migrated MariaDB to AWS RDS. The Worms player community never noticed the lift.

Alchemy Automotive · United Kingdom

A global automotive manufacturer

Multi-million-pound component testing rigs, all driven by 16-bit testing applications on Windows XP desktops. Replacing the rigs was not on the table. Replacing the desktops was overdue.

16-bit
Apps brought onto modern Windows
£M+
Capital investment in testing rigs preserved
0
Hardware replacement required

Critical testing processes continue uninterrupted, on a fully supported desktop estate. The rigs run for years to come.

Alchemy Safety · United Kingdom

A UK national safety organisation

A risk-averse culture, end-of-support deadlines on every front, and applications spanning Windows 7 desktops with IE 11 and Server 2003 back-ends.

2003
→ 2019/2022 server estate, lifted
7
→ Windows 10 desktops with Edge
0
Application refactoring required

Critical safety systems moved onto supported infrastructure, with the organisation's risk posture intact and the engineering team's focus undisturbed.

Guardian Financial services · United States

Federal Reserve compliance reporting

Detailed evidence, on demand, against US Federal Reserve configuration requirements. The kind of report that used to consume weeks now runs as a routine output.

CIS
Benchmark trend reports for the board
→
Stress and turnaround time reduced
FED
Evidence pack produced as standard output

Guardian turns audit preparation from a quarterly project into a continuous report. The IT team can prove improvement, not just compliance.

Guardian Enterprise IT · Change & release

Closing the loop on change tickets

Change reviewers needed to know exactly what changed, where, and whether it conformed to policy, in time to sign the change off cleanly.

→
Auto-raised incidents on policy breach
→
Out-of-window changes flagged automatically
100%
Audit-trail coverage in change system

Guardian sits inside the change window, watches the device, and writes the result back to the ticket. Approvers spend their time on judgement, not reconciliation.

Alchemy Banking · Cross-border

A data centre exit, accelerated

Multi-tier Windows 2008 applications, web servers, app servers, databases, all pinned to an existing data centre. The cloud provider was selected. The legacy was the blocker.

2008
Server workloads, fully decommissioned
DC
Exit completed on schedule
→
Security and resilience risks closed out

Alchemy isolates the application from the operating environment. The cloud provider gets a clean migration. The risk register loses an entry.

Alchemy Banking · Modernisation programme

A bank's phased modernisation

A large estate of Windows Server 2003 and Windows 7 systems, a finite engineering team, and a board that wanted proof before approving the full programme.

57
Server & desktop applications in scope
POV
Initial proof of value, business case approved
→
Phased delivery, in flight

A small initial engagement made the case. Alchemy is now the bank's preferred mechanism for modernisation, sequenced around the resources it actually has.

Alchemy Banking · Development environment

A bank's VB6 development stack, modernised

The development environment for a critical business application still ran on Windows Server 2003, with VB6 IDE and a stack of legacy plug-ins. The compliance team had run out of patience.

VB6
IDE & plug-ins packaged intact
2003
→ Server 2016, fully supported
0
Disruption to active development

Engineering kept building. The risk register cleared. The bank's compliance posture caught up with its application portfolio.

Guardian IT Services · Cross-border

A global IT services security team

385 nodes inside PCI scope, an incumbent file-integrity monitoring tool the team had outgrown, and an audit calendar that did not allow for a re-implementation gap.

385
Nodes migrated to Guardian for FIM
PCI
Compliance posture maintained throughout
1
Tripwire instance fully decommissioned

Guardian replaced the legacy file-integrity monitoring tool without losing audit coverage. The security team consolidated configuration management and FIM into a single platform.

Foundry VDI · AWS WorkSpaces

Foundry Flow for AWS WorkSpaces

Daily non-persistent VDI rebuilds were stretching past the maintenance window, and IT was rebuilding the same legacy applications every single morning before users logged in.

24/7
VDI availability protected
→
Apps preserved across daily rebuild cycle
0
Application source code changes

Foundry Flow packages the application once, then re-applies it cleanly to every freshly rebuilt WorkSpaces image. The maintenance window stops being a battle.

What now

Three problems. Three answers.

The fastest way to know whether Cloudhouse fits is to start with the problem that hurts most.

Guardian
Guardian

How confident are you in what changed last night?

Configuration drift, audit evidence, CIS benchmarks reported to the board. Continuous visibility of every device, every change, every policy breach.

Alchemy
Alchemy

Stuck on a system that should have moved years ago?

End-of-support deadlines, an audit you cannot fail, a cloud migration stalled at the application layer. Modernise the legacy estate without rewriting a line of code.

Foundry

VMware bills doubling, and rebuilds taking all night?

Move VMs into containers without rewriting the application. Cut infrastructure costs and bring AWS WorkSpaces rebuild cycles back inside the window.
