Optimising AWS Costs: The Power of a Well-Architected Review

Are your AWS bills higher than you anticipated, or do you lack clear visibility into your cloud spend?

Cloud computing promises cost savings, but without continuous optimisation, expenses can easily spiral. Many businesses find themselves paying for underutilised resources or inefficient configurations. An AWS Well-Architected Review, with its dedicated Cost Optimisation Pillar, is designed to identify these inefficiencies and provide actionable steps to reduce your AWS bill significantly.

The Cloud Cost Leakage

Common reasons for escalating cloud costs include over-provisioning, neglecting Reserved Instances, inefficient data transfer, and a lack of proper tagging. These hidden costs can erode your cloud ROI and diminish the perceived value of your migration.

How a Well-Architected Review Drives Cost Savings

Focusing on the Cost Optimisation Pillar, an AWS Well-Architected Review helps you:

  • Adopt a Consumption Model: Ensure you’re only paying for what you use and optimising your pricing models.
  • Measure Overall Efficiency: Set up monitoring and cost attribution to gain granular visibility into your spend.
  • Stop Undifferentiated Heavy Lifting: Identify areas where managed services can reduce operational overhead and costs.
  • Analyse and Attribute Expenditure: Understand where your money is going and assign costs to specific teams or projects.
  • Optimise Over Time: Implement continuous optimisation practices to ensure ongoing cost efficiency as your workload evolves.
  • Leverage Hybrid Benefit & Savings Plans: Identify opportunities to use existing licences and commit to usage for substantial discounts.

Maximising Cloud ROI

With cloud spending increasing, businesses are keenly focused on optimising their investment. A Well-Architected Review provides the structured approach needed to achieve significant and sustainable cost reductions.
