Legacy Modernisation and Cloud

Define clear modernisation strategies aligned to your priorities

The challenge CIO's face is how to approach legacy modernisation without disrupting the business or introducing new risk.

Entelect works with CIOs and CTOs to define clear modernisation and cloud strategies. We assess your estate, identify value at risk, and design a roadmap aligned to your commercial priorities, regulatory obligations, and risk appetite.

Our Work

Sanlam: Shaping Sanlam's cloud architecture 

Sanlam is modernising key mainframe based assets onto a more flexible, cost-effective technology stack. One of the early focus areas included the capabilities that support the money-out component of their retirement portfolios.

Sanlam's needed to move away from its existing mainframe towards a modern AWS-based architecture that could support future modernisation across the group.

Entelect played a strategic and technical role in shaping the cloud architecture from the outset. The focus was on making the right technology decisions early, with particular emphasis on cost management, cross-group reusability, standardised cloud patterns, and a foundation that could serve as a template for future mainframe modernisation initiatives.

Scale that manages spend: The architecture was designed to scale responsibly, helping avoid unnecessary over-provisioning while supporting future growth.
 
Reusability by design: Entelect helped standardise the cloud setup and architectural patterns with the wider Sanlam group in mind, not only the immediate project. These templates and approaches support phased delivery and reduce the risk associated with a large, big-bang migration from mainframe to cloud.
