Insourced IT Leadership for a Hybrid Cloud Migration

Description

Insourced IT Leadership for a Hybrid Cloud Migration

Sector: Financial Services
Service: IT Resourcing & Cloud Strategy
Objective: Provide a senior IT professional to lead a phased, low-risk hybrid cloud migration, ensuring scalability, resilience, and compliance with Australian regulations.

Context

A mid-sized financial services provider operating across several Australian states needed to modernise its ageing on-premises infrastructure. Increasing demands for scalability, cost efficiency, and faster service delivery were stretching existing systems to breaking point. Any move to the cloud, however, had to meet stringent Australian Prudential Regulation Authority (APRA) and data sovereignty requirements.

The client had trialled private cloud solutions, achieving a 30% reduction in operational workload. However, progressing to a hybrid cloud model was proving challenging due to complex regulatory considerations, integration with legacy applications, and the need to avoid disruption to core banking and customer services.

Approach

123.EXPERT insourced an experienced IT professional with deep expertise in cloud strategy, regulatory compliance, and large-scale migrations. Acting as the client’s interim Cloud Migration Lead, they:

  • Conducted a full workload and data flow analysis, mapping compliance obligations and operational dependencies.

  • Applied a risk-tiering framework to classify workloads by sensitivity and regulatory impact.

  • Directed the Phase 1 migration of low-risk development and testing environments to a public cloud provider with Australian data centres.

  • Designed and oversaw Phase 2, deploying customer-facing services in the public cloud while retaining sensitive back-end systems on private infrastructure, with secure, encrypted integration.

  • Re-platformed critical workloads (Phase 3) to make them cloud-ready, setting clear criteria for future migration under evolving regulations.

Throughout, the insourced leader worked alongside internal IT, compliance, and operations teams, embedding governance and building capability for ongoing cloud adoption.

Impact

With leadership from the 123.EXPERT professional, the client reduced deployment lead times by 50% and infrastructure costs by 20%, while fully meeting APRA and data sovereignty requirements. Internal teams gained practical skills in cloud management and governance, enabling them to continue migration phases independently. The result was a scalable, compliant hybrid cloud environment — and an in-house team better equipped to manage it.
