Closing the door to private cloud
On June 30 last year, PwC officially went full tilt into the cloud with a hybrid environment and no longer runs its owns data centres in Sydney and Melbourne.
The environment consists of a private cloud, provided by Telstra, which runs core business systems and represents about half of the firm's workloads. A significant proportion of applications are also running in a secure environment provided by Amazon Web Services, Google, and Microsoft Azure.
"What you get with cloud is resilience and operational stability. It isn't about lifting and shifting workloads, it's about transitioning workloads to a highly automated platform, which removes a lot of the manual tasks," Clune said.
"AWS was the first platform available to us, it was onshore so it met all of our sovereignty requirements, and architecturally, it's a very secure environment," said Clune. "We have closed the door to private cloud; we are using secure cloud platforms that are available to us.
"We also have a strategy specifically for core [apps] that is all about software-as-a-service first - we are not worried about the infrastructure. The lovely thing about Google [Cloud Platform] is we don't worry about growing our infrastructure, we don't do version upgrades of the software - it's all done in the background."
"SaaS for us is our first port of call unless it is differentiating or product that we want to launch to market - those things we will built to differentiate ourselves. But certainly from a wholesale business systems perspective, we will always try and move to software-as-a-service first."
