Cloudhouse Launches Alchemy APS to Free Banks From Legacy Infrastructure Lock-In

8 September 2025

Cloudhouse launches Alchemy APS to help banks decouple critical applications from legacy systems, enabling faster upgrades, improved resilience, and cost savings.

Cloudhouse, the UK company that liberates critical business applications from legacy technology dependencies, today announced the launch of Alchemy APS (Application Packaging and Provisioning), a breakthrough service designed to help banks separate critical applications from outdated infrastructure, enabling faster upgrades, improved resilience, and significant cost avoidance. Banks continue to face mounting pressure from regulators, security threats and the cloud transition agenda, yet many remain locked to legacy operating systems such as Windows Server 2008 or 2012. Traditional migration approaches - reliant on reinstall media, risky reconfiguration, or slow Ansible rebuilds - often stall projects, inflate costs, and increase risk. Cloudhouse Alchemy APS eliminates these barriers by decoupling applications from infrastructure and packaging them into portable, redeployable units. Banks can upgrade from legacy environments (e.g. Windows Server 2008 to 2022) in hours rather than days, without reinstalling or reconfiguring applications. It also means banks can modernise at speed while maintaining compliance, and preparing for the future, without being trapped by legacy technology. “For too long, critical banking applications have been tied to ageing infrastructure, creating bottlenecks for transformation programmes,” said Mat Clothier, CEO at Cloudhouse. “Alchemy APS provides a clean break, allowing banks to modernise faster, provision new environments instantly, and avoid unnecessary costs – all while maintaining resilience and compliance.” Key benefits of Alchemy APS for banks include:

Separation of applications from infrastructure - Apps are packaged and redeployed independent of the OS, avoiding delays caused by legacy dependencies.
Speed and efficiency - Upgrades and migrations reduced to hours; the only dependency is data migration speed.
Automation with flexibility - Step-based system (scan, manifest, package, deploy) enables both automation and human intervention, with packages tailored to server roles such as cards, payments, or core banking.
Resilience and compliance - Work carried out on cloned environments, never production, aligning with financial security standards.
Provisioning and environment flexibility - Beyond migration, banks can spin up test, pre-production, or feature environments instantly to meet project and regulatory deadlines.
Cost avoidance - Prevents unnecessary infrastructure overhauls or middleware spend, with no ongoing licence footprint once packaging is complete.

Cloudhouse is already supporting leading financial institutions, using Alchemy APS to avoid costly middleware upgrades while paving the way for a smooth transition to the cloud. For example, the company recently worked with a leading financial inclusion group operating across seven West African countries, dedicated to supporting micro-entrepreneurs and small businesses. The bank was operating on older versions of the Temenos Core Banking System (e.g., R10, R12 with role-based configurations) and needed to package each role efficiently to achieve infrastructure uplift without breakage. It also required the ability to work without registry entries (e.g., T24 on JBoss) and wanted an alternative that avoided costly upgrades, new modules, refactoring, or the adoption of an entirely new core banking system. With Alchemy APS, Cloudhouse successfully migrated the monolithic legacy versions of Temenos Core Banking to the latest servers across their operating countries, achieving resilience and modernisation without disruption. “Banks are under competing pressures - cloud mandates, regulatory deadlines, security threats and vendor upgrade cycles,” added Clothier. “Alchemy APS ensures they can modernise at speed, maintain compliance, and prepare for the future, without being trapped by legacy technology.”
