Horizon Power has completed a large-scale migration of applications and workloads from its data centres to a private cloud run by Macquarie Cloud Services. The shift to private cloud was for several reasons. The WA government wants agencies and owned companies to have more of a cloud mindset. In parallel, the government has set ambitious targets to reduce whole-of-government carbon emissions, and exiting its data centre was seen as a key way for Horizon Power’s Technology team to do its part. The private cloud choice was also partially for security reasons - Horizon Power has obligations under the Security of Critical Infrastructure or SOCI Act to contend with. Horizon Power is now set up to achieve some future-facing and data-driven ambitions, leveraging other cloud-based services.
