What we do

Four specialist disciplines

☁️

AWS & Cloud Architecture

Who we are

Hard opinions.
Real scale. No fluff.

CloudScale Consulting is a specialist technology consultancy led by Andrew Baker — Group CIO at Capitec Bank, former Director of Engineering EC2 at AWS, former CTO at ABSA Group. The advice comes from having actually operated these systems at the highest level — and knowing exactly where they break.

We focus on four disciplines where we have genuine depth: AWS architecture, cybersecurity, Zero Trust network access, and rearchitecting large-scale platforms that have hit their limits. If a recommendation hasn't survived contact with production, it doesn't make it here.
