Real-World Australian Implementation

A Parramatta accounting firm (20 employees) implemented multi-cloud architecture in 2021 using SageMaker.

The Challenge: Before 2021, they faced unreliable on-premise infrastructure, manual processes, and limited scalability. Existing approaches were proving inadequate as multi-cloud norm, ai/ml integration, sustainability emerging.

The Solution: They deployed a multi-cloud architecture solution built on SageMaker, taking advantage of 2021’s technological capabilities while working within the constraints of the era.

Implementation Approach:

  • Timeline: 4 months from planning to production
  • Team: 3-person team with external consulting support
  • Technology: SageMaker core platform with ML.NET
  • Budget: 4,000-10,000 setup + 400-1,000/month all-in for first year

The Results:

  • 52% cost reduction
  • 5x deployment acceleration
  • 99.99% availability
  • ROI positive within 7 months

Critical Success Factors:

  1. Realistic Expectations: Understood 2021 technology limitations
  2. Phased Approach: Started small, proved value, then scaled
  3. Training Investment: Allocated $1,500-3,000 for team upskilling
  4. Vendor Partnership: Selected vendor with strong Australian presence

Key Lesson: “Starting with SageMaker in 2021 gave us a solid foundation. While not as advanced as today’s solutions, it was production-ready and met our needs.” — IT Director
